5Workplace Safety Program
- In accordance to University policy and North
Carolina General Statute Article 63, each state
agency must have a written Health and Safety
program with clearly stated goals or objectives
that promote safe and healthful working
conditions. The Environment, Health and Safety
manual along with other specific manuals, such as
Radiation Safety Manual, Laboratory Safety
Manual, and Biological Safety manual serves as
the University's written Health and Safety
program. These manuals provide University
employees with the necessary guidance in
maintaining a safe work environment. Each of
these manuals can be viewed in more detail by
selecting "Manuals" from the EHS web site. - Other elements of the Workplace Safety program
include - Conduct new employee training to help with the
identification of and correction of hazards, - Review workplace incidents and develop ways to
eliminate or minimize hazards, and - Employee input through safety committees
6Workplace Safety Program
- UNC's health and safety committees perform
workplace inspections, review injury and illness
records, make advisory recommendations to the
administration, and perform other functions
determined by the State Personnel Commission. The
Workplace Safety Committees report through the
following structure - UNC employees should contact EHS or any committee
member regarding safety concerns.
7Workplace Safety Program
- If you are interested in serving on one of the
committees please feel free to contact the EHS
office at (919) 962-5507.
8Fire Safety Program
- UNC's Fire Safety program is based on NFPA 101
Life Safety Code, N.C. Fire Prevention Code, and
OSHA 1910 Subpart E. Your understanding and
contribution to Fire Safety is the key to an
effective fire protection program for the
University. Regularly inspecting your area for - electrical hazards
- storage in hallways
- blocked exit ways
- adequate lighting of exits
- general housekeeping
- can prevent a fire from occurring and provide
employees with a safe passage in the event of a
fire.
9Fire Safety Program
- If a fire or other emergency occurs in your
building, employees must know two Means of Egress
(exit). OSHA defines Means of Egress as "A
continuous and unobstructed way of exit travel
from any point in a building or structure to a
public way." The three main components of Means
of Egress are - The way of Exit Access
- The exit
- The way of Exit Discharge
10Fire Safety Program
Exit Access is the area in which an employee uses
as their means of exiting to an exit.
Exit Discharge is the exit from a building to a
public way.
Exit is the protected way of travel to the exit
discharge.
11Fire Safety Program
- The Department of EHS has prepared a general
Emergency Action Plan for the University to
follow. An Emergency Action Plan is "a plan for
the workplace describing what procedures the
employers and employees must take to ensure
employee's safety from fire and other
emergencies" (1910.35j). The plan includes - posting of planned evacuation routes
- procedures to follow in the event of a fire or
emergency - procedures to account for employees after
evacuation - procedures for employees who remain to operate
critical equipment in an emergency
12Fire Safety Program
- Posting of Planned Evacuation Routes - Building
evacuation procedure for your department should
be posted on the office bulletin board and at all
elevators. Employees should know at least two
evacuation routes for their designated work area
and any area that they frequent often. Employees
are encouraged to evaluate the building
evacuation areas daily to ensure that there are
no obstructions. If obstructions are found,
please report it to the EHS immediately at (919)
962-5507.
13Fire Safety Program
- Procedures to Follow - If a fire emergency was to
occur in your workplace, it is vital that you be
prepared to react. The acronym RACE provides the
basic steps of the Emergency Action Plan to
follow - Remove or rescue individuals in immediate danger
- Activate the alarm by pulling the fire pull
station located in the corridors and calling 911. - Confine the fire by closing windows, vents and
doors - Evacuate to safe area (know the evacuation routes
for your areas).
14Fire Safety Program
- Procedures to Account for Employees The
University has designated an Emergency
Coordinator(s) for all occupied buildings. Each
Emergency Coordinator (EC) is responsible for
assisting in the safe and orderly emergency
evacuation of employees. In preparation for an
emergency, the EC completes an information card
that includes - evacuation monitors' names
- employee names and phone numbers occupying
building - location of employees needing assistance
- rooms containing hazardous material,
- and equipment needing special attention.
15Fire Safety Program
- In an emergency, each Emergency Coordinator is
responsible for the following in accordance with
the University Emergency Plan - Sweep through assigned area to alert occupants
that an evacuation is in process. - Assist building occupants needing special
assistance - Report to the University Emergency Command Sector
with emergency information card - Advise emergency personnel regarding building
contents - Account for all employees by meeting building
occupants at the assembly area - Advise building occupants regarding situation and
when re-entry is permitted - Advise Facilities Services personnel in cleanup
operations.
16Fire Safety Program
- To extinguish a fire requires proper
identification of the type of fire extinguisher
to use. There are four classes of extinguishers
to choose from. - Currently University buildings are equipped with
Type ABC fire extinguishers, except in computer
labs or mechanical rooms with have CO2
extinguishers.
17Fire Safety Program
- Only University employees working in healthcare,
emergency response, and/or whose job requires
them to use a fire extinguisher are required to
receive annual hands on fire extinguisher
training. EHS Fire Safety section conducts annual
classes in different locations on campus. For
other employees it is beneficial to know how a
fire extinguisher is used. Remembering the
acronym PASS will assist in the proper use of a
fire extinguisher. - Pull the pin between the handles.
- Aim the nozzle at the base of the fire.
- Squeeze the handles together.
- Sweep the extinguisher from side to side at the
base of the fire.
18Fire Safety Program
- A few fire safety reminders
- Everyone is responsible for keeping the work area
safe from fires. - Review your evacuation routes to ensure that
exits and passageways are unobstructed. - Practice good general housekeeping.
- Store flammable liquids and combustible material
properly. - Report any fire hazards or other safety concerns
immediately to the department of Environment,
Health and Safety at (919) 962-5507.
19Workers Compensation Program
- Workers' Compensation benefits are available to
any University employee (whether full-time,
part-time, temporary) who suffers disability
through accident or illness arising out of, and
in the scope of, his or her employment, according
to the North Carolina Workers' Compensation Act.
20Workers Compensation Program
- The benefits provided to University Employees
include medical and leave. Medical benefits
include all authorized medical services such as
physician visit, prescriptions, physical therapy,
rehabilitation, etc. Leave benefits are provided
to employees when an authorized medical provider
places an employee out work.
21Workers Compensation Program
- If you receive an injury or occupational illness,
go directly to the University Employee
Occupational Health Clinic (UEOHC) located at 145
N. Medical Drive. The UEOHC is open from 830 am
to 430 pm Monday thru Friday, except holidays. - For after hours needlestick/human blood or body
fluid exposures, please call UEOHC at 966-9119.
The UEOHC line will automatically forward your
call to Healthlink in order to gather the
appropriate information and put you in contact
with the Family Practice physician covering the
needlestick hotline. For all other after-hour
work related injuries that require immediate
medical care, go directly to the UNC Emergency
Department. If immediate medical care is not
needed, then please report to the UEOHC the
following day. - For a life-threatening injury or illness, go
directly to the Emergency Department located in
the Neurosciences Hospital on Manning Drive.
22Workers Compensation Program
- If you experienced an on-the-job injury or
illness, you are to report the incident
immediately to your supervisor no matter how
minor. Once the injury is reported, an incident
investigation will occur to determine the cause
of the incident and corrective action taken to
prevent the incident from reoccurring. Please
note Failure to report an injury could result in
the denial of your claim.
23Workers Compensation Program
- For further information concerning University
policies on workplace injuries and illnesses,
refer to the "Workers' Compensation" pages on the
EHS web site.
24Hazard Communication Program
- The OSHA Hazard Communication standard
(1910.1200) requires that employees be informed
of the hazards of chemicals that they may work
with or are present in their work area. The four
elements of this program are - Labeling
- Hazardous Chemical Inventories
- MSDS
- Training
- Each of these elements will be reviewed in more
detail.
25Hazard Communication Program
- All containers of hazardous chemical must be
labeled with at least three items - the name of the chemical,
- any hazard warnings associated with the product
and, - the name and address of the manufacturer.
- The name of the chemical must be spelled out
completely, no molecular formulas are allowed.
26Hazard Communication Program
- All departments must maintain a current Chemical
Inventory List that is reviewed and updated at
least annually. - Example HAZARDOUS MATERIALS INVENTORY
27Hazard Communication Program
- Material Safety Data Sheets must be accessible 24
hours a day. MSDSs are prepared and distributed
by the chemical manufacturer or distributor to
provide important information concerning the
chemical in question. MSDSs contain the identity
of the chemical, the manufacturer's name, address
and phone number and information regarding the
physical and chemical characteristics of the
chemical such as toxicity, flammability,
corrosively physical and health hazards such as
exposure hazards exposure limits precautions
and controls and emergency and first aid
treatment for exposures. A MSDS must be available
for every chemical on the department's Chemical
Inventory List.
28Hazard Communication Program
- All University employees who work with chemicals
or have chemicals in their workplace are required
to have hazardous materials' training initially
upon employment and when any new chemical are
introduced in their workplace thereafter. - The Supervisor of employees who will be working
with hazardous material will provide more
in-depth training. - The training will cover
- the proper use,
- handling, and
- personal protective equipment
- required for the safe handling of all hazardous
chemicals. This training is mandatory for all
employees handling hazardous materials.
29Hazard Communication Program
- EHS is available to assist any department,
supervisor, and/or employees with information
concerning the University's Hazard Communication
Program, Material Safety Data Sheets, etc. Please
feel free to contact EHS at (919) 962-5507.
30Clinical Safety Program
- The clinical safety program at UNC is designed to
promote environments that are free of hazards
specific to clinical environments. Clinical
environments are classified as areas such as
healthcare facilities, laboratories that are
dealing with blood or bodily fluids, or any other
facility that is dealing with procedures that
involve hazardous materials and biological
agents. These areas need special attention to
hazards to protect both the employees and the
patients.
31Clinical Safety Issues
- In the clinic environment safety issues arise
that are specific to personnel working in a
healthcare facility. All University healthcare
workers are expected to conduct their daily
activities in such a way that they do not expose
themselves or others to potential injury, such
as - Needlestick or sharp injuries
- Back injuries
- Chemical exposures
- Slips and falls
32Needlesticks or Sharp Injuries
- Needlesticks or sharp injuries are instances
where an employee was exposed to a needle or
other sharp tool or object, and were injured.
These injuries normally break the skin and expose
the employee to blood or other bodily fluids. - Certain measures may be taken to reduce exposure.
These measures include using appropriate
engineering controls and using proper personal
protective equipment (PPE).
33Needlesticks or Sharp Injuries, cont.
- Engineering controls are used to isolate or
remove the bloodborne pathogens hazards from the
workplace. Examples may include but are not
limited to sharps disposal containers,
self-sheathing needles, and safer medical
devices, such as sharps with engineered sharps
injury protectors and needleless systems.
Personal Protective Equipment (PPE) is
specialized clothing or equipment worn by an
employee for protection of a hazard.
34Lifting Techniques
- Proper lifting techniques are also important in
clinic environments. An employee should maintain
good body posture, use safe body mechanics (bend
at the hips and knees, not at the waist), and
assess the situation of a patient before lifting
or transferring a patient. - An employee may also use lifting devices to aid
them in achieving proper lifting techniques. In
the healthcare facilities, there are devices
which aid employees when lifting a patient.
35Chemical Exposures
- Following appropriate procedures when exposed to
chemicals or other hazardous materials is
necessary for preventing incidents. Hazardous
materials are those substances that are
potentially hazardous to your safety and health.
Employees may encounter many hazardous materials
that are classified as health and/or physical
hazards. - A health hazard is anything that causes acute or
chronic health effects. A physical hazard is any
chemical that is flammable, an oxidizer, or
corrosive..
36Chemical Exposures, cont.
- Examples of hazardous materials in the clinic
environment include infectious waste, flammable
liquids and gases, toxic chemicals, radioactive
materials, cancer causing (carcinogens) chemicals
and drugs, and compressed gas cylinders. - All departments using hazardous chemicals are
responsible for determining if a less hazardous
chemical may be substituted. The unsafe handling
of hazardous materials can have an impact on
ambulatory care or hospital operations.
Appropriate precautions should always be used in
handling hazardous materials..
37Slips and Falls
- Another example of incidents that are common in
the clinic environment is slips and falls.
Employees should be aware of their surroundings
and should pay particular attention to areas
where there could be potential moisture on the
floor or walking surface that might cause them to
slip or fall.
38Needlestick Safety and Prevention Act
- The Needlestick Safety and Prevention Act became
law in 2000. This law revised the Bloodborne
Pathogens Standard (29 CFR 1910.1030) to include
safer medical devices, such as sharps with
engineered sharps injury protections and
needleless systems, as examples of engineering
controls designed to eliminate or minimize
occupational exposure to bloodborne pathogens
through needlesticks and other percutaneous
exposures.
39Requirements
- Requirements of the needlestick safety and
prevention act include - Review and update exposure control plans to
reflect changes in technology that eliminate or
reduce such exposure, - Document the consideration and implementation of
appropriate commercially available, safer medical
devices that eliminate or reduce exposure, - Maintain a sharps injury log, noting the type and
brand of device used, where the injury occurred,
and an explanation of the incident, - Seek input on such engineering and work practice
controls from the affected healthcare workers.
40Needlestick Safety and Prevention at UNC
- UNC makes every attempt to ensure safety for all
employees who are exposed to needles and other
sharps. Needlesticks are one of the most common
incidents in the workplace. UNC and
UNC-Healthcare have formed a Needlestick Task
force that convenes twice a year to examine and
evaluate techniques and protocols to stay abreast
of innovative technologies to decrease the number
of needlestick occurrences. In addition, members
of the Occupational Health/Clinical Safety
Committee also address needlestick safety and
prevention.
41Latex Exposure
- A recently recognized work place hazard for some
healthcare workers is latex exposure. For some
individuals exposure to latex products, such as
powdered latex exam gloves, can cause a mild to
severe allergic reaction.
42Latex Allergy Prevention
- To prevent latex allergies do the following
- Use non-latex gloves for activities that are
likely to involve contact with infectious
substances - If you choose latex gloves, use powder-free
gloves - When using gloves, do not use oil-based hand
cream or lotions - Recognize the symptoms of latex allergy
- Always wash hands after removing gloves
43Latex Allergy
- If you believe that you may have a latex allergy,
you should notify your supervisor and contact the
University Employee Occupational Health Clinic
(UEOHC) for evaluation at (919) 966-9119.
Additional information regarding potential
hazards associated with latex exposure is also
available by contacting the UEOHC.
44Disaster Plan Manuals
- The UNC Department of Environment, Health and
Safety, UNC Hospitals and some specific
departments have Disaster Plan Manuals that
provide all employees with a written resource to
accomplish an effective response to disaster
events. The UNC EHS plan can be found at EHS's
online manual. - The Director-on-Call and the Disaster Commander
will assess the need for personnel, supplies, and
equipment. In addition, all departments need to
have an internal plan on what to do during a
disaster.
45If a Disaster Occurs
- If a disaster occurs which compromises the
utilities of the facility, it should be reported
to the Facilities Services Division (919)
962-3456 in University buildings and Plant
Engineering (919) 966-4484 in Hospital buildings.
46ID Badges
- It is imperative that employees wear their ID
badges at all times. These badges will include
emergency code announcements and steps to take in
the event a code is called. ID badges are also an
essential part of the health and safety system
due to security issues.
47Hazard Assessment and Equipment Selection
- The department in consultation with the
Department of Environment Health and Safety will
assess the workplace to determine if hazards are
present, or likely to be present, and requires
the use of Personal Protective Equipment (PPE).
If such hazards are present, or likely to be
present, the University will - Select and have each affected employee use the
types of PPE that will protect the affected
employee from the hazards identified in the
hazard assessment.
48Hazard Assessment and Equipment Selection, cont.
- Communicate selection decisions to each employee
- Select PPE that properly fits each affected
employee - Verify that the required workplace hazard
assessment has been performed through a written
certification that identifies the workplace
evaluated, the person certifying that the
evaluation has been performed, and the dates of
the hazard assessment.
49Hazard Assessment and Equipment Selection, con't.
- Employees working in a clinical facility must
wear proper personal protective equipment. An
assessment should be conducted to determine
proper personal protective equipment. Below you
will find an example of a hazard assessment for
employees working in a healthcare environment.
Also, remember to always use standard precautions
as all patients are potentially infectious.
50Personal Protective Equipment (PPE)
- Personal Protective Equipment should be
- Inspected before and after each use
- Used where there is occupational exposure
- Used appropriately
- Used only when its integrity is insured
- Accessible
- Removed when contaminated and prior to leaving
the work area
51PPE Training
- The University will provide training to each
employee who is required to use PPE. Each
affected employee shall demonstrate an
understanding of the training and the ability to
use PPE properly, before being allowed to perform
work requiring the use of PPE. The training
program must verify that each affected employee
has received and understood the required training
through a written certification that contains the
name of each trained employee, the dates of
training, and that identifies the subject of the
certification.
52PPE Training, cont.
- Each employee is to be trained to know at least
the following - when PPE is necessary
- what PPE is necessary
- how to properly don (put on), doff (take off),
adjust, and wear PPE - the limitations of the PPE
- the proper care, maintenance, useful life and
disposal of the PPE
53PPE Training, con't.
- The training program must verify that each
affected employee has received and understood the
required training through a written certification
that contains the name of each trained employee,
the dates of training, and that identifies the
subject of the certification. Click this link for
a certification form for Personal Protective
Equipment.
54Training and Medical Surveillance Program
- OSHA and JCAHO regulations require that all
employees who have duties in or are located in a
healthcare facility receive medical surveillance
and attend additional safety training.
55Medical Surveillance
- All healthcare employees are required to complete
a one-time immunization review through the UEOHC.
The immunization review consists of - A record of 2 Measles, 2 Mumps, and 2 Rubella
(disease or vaccine for all) OR titers for all OR
a record of 1 Tdap (Tetanus, diptheria, acellular
pretusis) - A record of the Hepatitis B series (for those
exposed to blood or bodily fluids) - Verbal response for Varicella (Chicken Pox)
- Verbal response for Latex Allergy
- Annual Tuberculosis Screening
56Medical Surveillance, cont.
- Annually thereafter, employees are to complete a
Tuberculosis Screening through the UEOHC. UNC
Environment, Health and Safety will notify
employees who need to renew his/her TB screening
via campus mail the month that it is up for
renewal. Department representatives will also
receive monthly compliance reports stating the
current status of their employees.
57Training
- Employees who are classified as working in a
clinic environment are required to complete
annual training on JCAHO/General Safety,
Tuberculosis, and Bloodborne Pathogens for those
who are potentially exposed to blood or other
bodily fluid. These training requirements can be
completed either by utilizing EHS's online
self-study units or by attending instructor led
classes which are held every month. For more
details, select the training section on the EHS
Website.
58Bloodborne Pathogen Introduction
- On December 6, 1991, the Occupational Safety and
Health Administration (OSHA) published their
standard for occupational exposure to bloodborne
pathogens in the Federal Register 1910.1030,
which can be found at the following website
www.osha.gov. A component of this standard
requires the employer to provide annual education
regarding the occupational hazard of bloodborne
pathogens. There are 14 required components of
this education all of which are incorporated in
this study module.
59Bloodborne Pathogen Intro., cont.
- These components are listed in the Federal
Register 1910.1030. It is important to remember
that OSHA standards are federal law and
compliance is mandatory. However, it is more
important to recognize that this standard was
established to help protect the healthcare worker
from the serious workplace hazard of bloodborne
pathogens.
60Bloodborne Pathogens
- Bloodborne Pathogens are pathogenic
microorganisms that are present in human blood or
other potentially infectious materials (OPIM) and
can cause disease in humans. These pathogens
include but are not limited to - Human Immunodeficiency Virus (HIV)
- Hepatitis B (HBV)
- Hepatitis C (HCV)
- Non A, non B Hepatitis
- Syphilis
- Malaria
61Other Potentially Infectious Material (OPIM)
- OPIMs are body fluids, unfixed tissues or organs,
and tissue that may cause disease in humans.
Listed below are some examples - cerebrospinal fluid
- synovial fluid
- pleural fluid
- amniotic fluid
62Other Potentially Infectious Material (OPIM),
cont.
- pericardial fluid
- unfixed tissue or body organs other than intact
skin - blood, organs, and tissue from experimental
animals infected with HIV or HBV - peritoneal fluid
- semen
- vaginal secretions
- any body fluid contaminated with blood saliva in
dental procedures - body fluids in emergency situations that cannot
be recognized
63Epidemiology of HIV
- Bloodborne Pathogens are pathogenic
microorganisms that are Human Immunodeficiency
Virus (HIV) is the virus that causes AIDS. This
virus is passed from one person to another
through blood-to-blood and sexual contact. In
addition, infected pregnant women can pass HIV to
their baby during pregnancy or delivery, as well
as through breast-feeding. People with HIV have
what is called HIV infection. Most of these
people will develop AIDS as a result of their HIV
infection. - According to the CDC, as of 2002, approximately
65 million people worldwide have been infected
with HIV. At the end of 2002, an estimated 42
million people worldwide were living with HIV
infection or AIDS. In the United States, through
December 2001, a total of 816,149 cases of AIDS
had been reported to the CDC.
64HIV and AIDS Current Trends
- According to current trends, these certain
populations are at a greater risk of contracting
HIV/AIDS - Injecting-drug users
- Women
- Blacks
- Hispanics
- Adolescents/young adults
- Persons who are involved heterosexually with a
partner at risk or known to have the infection or
AIDS.
65Clinical Manifestation of HIV Infection
The spectrum of HIV infection ranges from an
asymptomatic state to severe immunodeficiency and
associated opportunistic infections, neoplasms,
and other conditions. Initial infection can be
followed by an acute flu-like illness. Features
include
- rash
- malaise
- sore throat
- headache
- fever
- lymphadenopathy
- sweats
- myalgia
- arthralgia
66Clinical Manifestation of HIV Infection, cont.
- The natural history can vary considerably. The
risk of disease progression increases with the
duration of the infection. Most cohort studies
show that less than 5 of HIV infected adults
develop AIDS within 2 years of infection. Without
therapy approximately. 20-25 develop AIDS within
2 years of infection and 50 within 10 years.
67Epidemiology of Hepatitis B Virus
- Acute viral hepatitis, first reported in 1833, is
a common and sometimes serious viral infection of
the liver leading to inflammation and necrosis.
There are at least five distinct viral agents
that cause acute viral hepatitis - HAV
- HBV
- HDV (delta)
- HCV
- HEV (an externally transmitted non A, non B
hepatitis agent) - As of 2001, the United States had 78,000 cases of
Hepatitis B reported to the CDC.
68Clinical Manifestation of HIV Infection
- The clinical presentation of acute HBV ranges
from asymptomatic, subclinical illness to
fulminant hepatic failure. The disease has a long
incubation period from 30 to 180 days. Initial
symptoms are nonspecific, typically include
- rash
- polyarthritis
- last 3-10 days
- onset of jaundice or dark urine
- severe acute liver failure
- elevations of ALT and AST
- last 3-10 days
- onset of jaundice or dark urine
- severe acute liver failure
- elevations of ALT and AST
69Hepatitis B Vaccine
- The Hepatitis B vaccine is given as a series of
three injections. It produces a high antibody
titer in over 90 of the recipients under the age
of 40-50 years. Certain factors such as older
age, obesity, heavy smoking, and immunologic
impairments can result in lower antibody titers. - Hepatitis B is offered to all UNC Employees who
have reasonably anticipated exposure to blood or
other potentially infectious material. The
Hepatitis B vaccine is given to these employees
to try and reduce the risk of seroconversions due
to a Hepatitis B exposure. It is given at the
UEOHC (919-966-9119). If you decline, you must
sign a declination form, however if you desire it
at a later time, you may receive it then.
70Epidemiology of Hepatitis C Virus
- Hepatitis C (HCV) is a viral infection of the
liver. Hepatitis C is a major cause of acute
hepatitis and chronic liver disease, including
cirrhosis and liver cancer. Globally an estimated
170 million persons are chronically infected with
HCV and 3 to 4 million persons are newly infected
each year.
71Clinical Manifestation of Hepatitis C Virus
- 80 of the persons infected with Hepatitis C have
no signs or symptoms. Those that have symptoms
and signs, may exhibit the following
- Jaundice
- Fatigue
- Dark Urine
- Abdominal Pain
- Loss of Appetite
- Nausea
Chronic infections occur in 75-85 of infected
persons. Chronic liver disease occurs in 70 of
infected persons. Hepatitis C is the leading
indication for liver transplants. There is no
vaccine for Hepatitis C. Employees who acquire
HCV occupationally or suspect an exposure
incident, should contact the University Employee
Occupational Health Clinic (966-9119).
72Transmission
- In the occupational setting transmission of
bloodborne pathogens is by needlestick/sharp
injuries, mucous membrane and non-intact skin
exposure to contaminated blood/OPIM. In general,
HIV and hepatitis B virus are transmitted via the
following routes - sexual contact
- sharing HIV or HBV contaminated needles or
syringes - from mother to unborn child
73Transmission, con't.
- Hepatitis C is spread primarily by direct contact
with human blood. The major causes of HCV
infection include - Unscreened blood transfusions
- Re-use of needles and syringes
- Injecting drug users
- From infected mother to baby during birth
- Sharps exposures or Needlesticks
74Rule of Threes
- Not all the bloodborne pathogens carry the same
risk of occupational acquisition. Frequency in
patient population, environmental viability of
the virus, and viral load all impact your risk of
acquiring infection, if exposed. The following
table demonstrates infection risk from a
percutaneous exposure to HBV, HCV, and HIV.
75Exposure Control Plan
- UNC has two exposure control plans available to
all employees. One is for the UNC Healthcare
System and is available at www.unchealthcare.org
and the other you may call the Department of
Environment, Health and Safety at (919) 962-5507
to receive a copy or visit ehs.unc.edu. The
Exposure Control Plan contains a list of all job
categories that have occupational risk to
bloodborne pathogens. It also outlines management
of employee exposures and methods to prevent
exposure in the workplace. A copy of the OSHA
standard can be referenced directly behind the
Exposure Control Plan. Every employee should be
familiar with the Exposure Control Plan and the
OSHA standard.
76Standard Precautions
- Standard Precautions is a method of infection
control in which all human blood and other
potentially infectious materials (OPIM) are
treated as known to be infectious. Standard
Precautions apply to blood, all body fluids,
secretions, and excretions (except sweat),
non-intact skin, and mucous membranes. They are
essential in reducing occupational acquisition of
bloodborne pathogens. This means treating every
patient as if they were infected with bloodborne
pathogens, such as HIV or HBV. It also means that
healthcare workers use personal protective
equipment to prevent direct contact with blood or
body fluids. Standard precautions is the best
method that healthcare workers can use to protect
themselves from occupational acquisition.
77Personal Protective Equipment
- Personal Protective Equipment (PPE) is
specialized clothing and equipment worn by
employees for protection against a hazard, such
as blood or other potentially infectious
materials. This equipment should be readily
available and is provided to the employee at no
cost. - The employees should never put themselves at risk
by not using appropriate PPE and should be
removed after use. The employees should take care
not to contaminate the skin. Soiled gowns,
gloves, etc should be disposed of in a Biohazard
Container immediately after use. Hands should
always be washed thoroughly after removal of PPE.
78Engineering Controls
- Engineering controls are used to isolate or
remove the bloodborne pathogen hazards from the
workplace (e.g. sharps disposal containers,
self-sheathing needles, and safer medical
devices). Employers are required to provide
engineering controls that have been demonstrated
to significantly reduce occupational hazard.
79Administrative Controls
- Administrative controls are used to reduce the
likelihood of exposure by altering the manner in
which a task in performed. Some examples include
needles not being recapped, specimens transported
in secondary container. It could also be
displayed by sharps being immediately disposed in
a sharps container. Healthcare workers are
responsible for carefully disposing of all
sharps.
80Transporting Specimens to the Laboratory
- When transporting specimens, they should not be
hand carried to the lab. Specimens must be
transported in a secondary container displaying a
BIOHAZARD label. The primary specimen container
and accompanying tags and/or labels must be
contaminant free.
81Universal Biohazard Sign
- Universal Biohazard Signs are used to alert
employees that containers, specimen
refrigerators, or secondary containers used to
transport specimens may contain infectious
materials. Individual tubes need not be labeled.
Secondary containers used for manually
transporting specimens must display the BIOHAZARD
sign. Equipment that may have internal
contamination that cannot be accessed for
decontamination should also be tagged with a
BIOHAZARD label. Biohazard signs alert
maintenance and medical engineering employees to
use precaution.
82Contaminated Equipment
- Equipment such as blood pressure cuffs and
stethoscopes must be cleaned if contaminated with
blood or other potentially infectious materials.
An EPA approved disinfectant detergent (i.e.
Vesphene) or a 110 or 1100 dilution of bleach
and water should be used.
83Disposing of Medical Waste
- Regulated medical waste is infectious waste that
is to be disposed of according to rules
established by the North Carolina Solid and
Hazardous Waste Management Branch. Regulated
medical waste includes full Sharp Containers,
microbiological cultures, pathology specimens,
and gt20ml of blood products which includes
Blood, serum, plasma, emulsified human tissue,
spinal fluid, pleural and peritoneal fluid. - Medical waste must be disposed in a container
labeled with the BIOHAZARD label. Certain items
are required to be incinerated and are referred
to as regulated medical waste. Blood in
quantities of greater than 20ml per unit
container is defined as regulated medical waste.
84Disposing of Regulated Waste
- When transporting specimens, they should not be
hand carried to the lab. Specimens must be
transported in a secondary container displaying a
BIOHAZARD label. The primary specimen container
and accompanying tags and/or labels must be
contaminant free.
85Disposal of Medical Waste
- Bandages, dental floss, vacutainer tubes, and
bags do not require incineration or autoclaving
are to be disposed in white trash bags labeled
with the BIOHAZARD SIGN. It is important to
remember that bags are not puncture-proof and
sharps are always to be disposed in designated
sharps containers, not in trash bags.
86Wet, Contaminated Laundry
- Wet contaminated laundry is laundry that is
soiled with blood or other potentially infectious
materials and presents a reasonable likelihood to
soak through or leak from the bag. This laundry
should not be sorted or handled any more than
necessary for disposal. It should be disposed in
fluid resistant linen bags and should be doubled
bagged when necessary to prevent leaking.
87Dermatitis of the Hands
- Some employees may develop dermatitis of the
hands. This puts the employee at greater risk of
infection with bloodborne pathogens. All
employees who develop or suspect that they may
have dermatitis of the hands, should be seen at
the University Employee Occupational Health
Clinic. This process will provide evaluation and
treatment prior to work involving exposure to
blood, to help minimize the risk of infection
with bloodborne pathogens.
88Latex Allergy
- Latex gloves have proven effective in preventing
transmission of many infectious diseases,
however, for some healthcare workers, exposure to
latex may result in allergic reactions. This
reaction is to certain proteins in latex rubber.
The amount of latex exposure needed to produce
sensitization or reaction is unknown. - Symptoms may occur within minutes of exposure or
may take several hours to appear depending on the
individual. They may include skin redness,
hives, itching, respiratory symptoms such as
runny nose, itchy eyes, scratchy throat, and
asthma. If an employee has a latex allergy or
suspects they have had any reaction to latex,
they should report the incident to the University
Employee Occupational Health Clinic.
89Protection From Latex Allergy
- There are certain precautions employees can take
to protect themselves from a latex allergy. Use
non-latex gloves for activities that are not
likely to involve contact with infectious
materials. Appropriate barrier protection is
necessary when handling infectious materials, so
if you choose latex gloves, use powder-free
gloves with reduced protein content. When wearing
latex gloves, do not use oil-based hand creams or
lotions. After removing latex gloves, wash hands
with a mild soap and dry thoroughly. Frequently
clean areas and equipment contaminated with latex
dust. Learn to recognize the symptoms and
procedures for preventing latex allergy.
90Exposure Incidents
- Exposure incidents are events in which there has
been a - percutaneous injury involving a potentially
contaminated needle or other sharp - splash of blood or other potentially infectious
materials to the eyes, mouth, or mucous membranes
- blood or other potentially infectious materials
contacting broken skin - At UNC in 2002, there were 72 exposure incidents
reported. Two of the source patients were HIV
positive, three were HBV positive, and five were
HCV positive. There were no seroconversions as a
result of exposure to HIV, HBV, or HCV positive
blood.
91Steps to Take in the Event of Exposure
- In the event of an exposure, employees should
- Immediately wash the exposed area with soap and
water. If the eyes are involved, irrigate with
tap water. - Notify your supervisor and complete an incident
report - Go to the University Employees Occupational
Health Clinic, calling ahead (919-966-9119) to
alert them of the exposure. - If the exposure occurs after regular working
hours or on weekends, call Health Link
(919-966-9119) to be instructed on steps
necessary for further treatment.
92Occupational Health Clinic Evaluation
- The University Employee Occupational Health
Clinic (UEOHC) staff will evaluate your exposure
incident. The evaluation may include testing your
blood and the source patients' blood for HIV,
HBV, and HCV. This test is only conducted with
the employees consent and is kept confidential.
After the results are known, UEOHC will provide
the employee with written evaluation and
recommendations regarding the treatment of
exposure. In some cases a combination therapy for
HIV exposure may be considered.
93Tuberculosis Introduction
- Healthcare facilities present an environment
where tuberculosis may be transmitted at an
increased rate. Patients with active disease may
expose other patients, some of whom are highly
susceptible for contracting TB due to immune
deficiencies. The high risk for transmission of
TB in healthcare facilities presents an
occupational health hazard for employees who work
in healthcare facilities. In 1990 and 1991, CDC
received 13 reports of outbreaks of MDR-TB in
hospitals and prisons. These outbreaks resulted
in the disease being spread to healthcare
workers.
94OSHA Requirements
- OSHA does not have specific regulations
concerning the control of tuberculosis
infections. However, OSHA has stated that it will
cite healthcare facilities, under the General
Duty Clause of the OSHA Act, for non-conformance
to published CDC guidelines for TB control. These
guidelines require that healthcare employees
receive annual training in TB and infection
control. Successful completion of this training
module will satisfy those requirements.
95Current Trends of TB
- After decades of decline, the number of cases of
active tuberculosis has been on the increase
since the mid 1980s. This increase and the
concern for occupational exposure for healthcare
workers has been attributed to - HIV epidemic. Individuals who are HIV positive,
or have other immune deficient conditions, have a
greater risk of developing active TB disease if
infected. - Immigration. Foreign-born individuals have come
from countries with high prevalence of TB, such
as Asia, Africa, the Caribbean, and Latin
America. These individuals may also live in
medically under served areas within the U.S.,
which further contributes to the increased risk
for TB transmission.
96Current Trends of TB, cont.
- Transmission in high-risk environments.
Transmission of tuberculosis accelerates in
environments where there are - persons with active TB, and
- persons with a higher risk for progression from
latent TB to active disease. - Such environments include homeless shelters,
prisons, nursing homes, and hospitals. - Drug Resistance. Multi-drug-resistant
tuberculosis (MDR-TB) refers to strains of M.
tuberculosis that are resistant to isoniazid and
rifampin, two drugs used to treat TB. Patients
who become infected with these strains of TB take
longer to recover and remain infectious for a
longer period, thus, potentially infecting more
people.
97Current Trends of TB, con't.
- Exposure incidents are events in which there has
been a - percutaneous injury involving a potentially
contaminated needle or other sharp - splash of blood or other potentially infectious
materials to the eyes, mouth, or mucous membranes
- blood or other potentially infectious materials
contacting broken skin - At UNC in 2002, there were 72 exposure incidents
reported. Two of the source patients were HIV
positive, three were HBV positive, and five were
HCV positive. There were no seroconversions as a
result of exposure to HIV, HBV, or HCV positive
blood.
98Decline in TB Cases
- The decline in cases during 1992-1997 can be
- attributed to the following six factors
- improved laboratory methods to allow prompt
identification on M. tuberculosis - broader use of drug-susceptibility testing
- expanded use of preventive therapy in high-risk
groups - decreased transmission of M. tuberculosis in
congregative settings (e.g. hospitals,
correctional facilities)
99Decline in TB Cases, cont.
- improved follow-up of persons with TB initially
reported to the health department - increased federal resources for state and local
TB-control efforts. - In North Carolina the number of cases remains
stable at approximately 600 cases per year. Less
than 1 of TB cases that have occurred in North
Carolina have been MDR-TB. At UNC Hospitals,
there are approximately 25 cases of TB out of
27,000 admitted patients each year.
100Transmission of TB
- M. tuberculosis is carried in airborne particles,
or droplet nuclei, generated when a person with
pulmonary or laryngeal TB coughs or sneezes.
Infection occurs when a susceptible person
inhales droplet nuclei containing M. tuberculosis
bacilli, which reach the alveoli of the lungs.
Within 2-10 weeks after initial infection the
immune response limits further spread of tubercle
bacilli however, some of the bacilli remain
dormant and viable for many years. This is known
as latent TB infection.
101Transmission of TB, cont.
- For a small proportion of infected persons
(usually lt1 ), initial infection readily
progresses to clinical illness, or active
disease. For 5 - 10, illness develops after an
interval of months, years, or decades, when the
bacteria begin to replicate and produce disease.
Progression to active disease is more likely in
persons with medical conditions that result in
immune deficiencies, the elderly, and those less
than 4 years of age. The risk for progression to
active disease is markedly increased for persons
with HIV infection.
102Transmission of TB, con't.
- TB infection occurs after prolonged exposure to
someone who has the infectious form of TB. A
person has a 50 chance of becoming infected if
they spend 8 hours a day for 6 months with a
person with the active form of TB. - The site of initial infection is usually the
alveoli of the lungs where macrophages ingest the
inhaled bacilli. The body's T-cells are
stimulated and a cell-mediated or delayed
hypersensitivity occurs. - The T-cells stimulate specialized cells that kill
the bacilli and wall off infected macrophages,
producing grayish capsules called tubercles.
Further multiplication of the TB bacilli are
usually confined here. In an immunodeficient
individual the TB bacilli may break out of the
tubercle and lead to the active form of the
disease.
103Infection Routes and Symptoms
- For individuals with active TB, the bacilli will
spread from the lungs to other parts of the body
usually the lymph nodes. In 15 of the active TB
cases, bacilli will infect other sites in the
body such as the skin, bones, and reproductive or
urinary systems. - Symptoms of the disease include weight loss,
fever, night sweats and anorexia. If the disease
is allowed to progress, large cavities may form
in the lungs, encompassing the bronchi. Symptoms
also include a persistent (lasting at least three
weeks) cough with production of bloody sputum.
104Diagnosis of TB
- Persons exhibiting the symptoms and suspected of
having TB, should be referred for a complete
medical evaluation, which should include a
medical history, physical examination, a Mantoux
tuberculin skin test, a chest radiograph, and
appropriate bacteriologic or histological
examinations.
105Tuberculin Skin Test
- The Mantoux or tuberculin skin test is used for
screening individuals who are at high risk for
developing tuberculosis, such as persons exposed
to infectious individuals. The tuberculin skin
test is the only method of diagnosing TB
infection before the infection has progressed to
the active disease. A person who becomes infected
with TB will show a positive reaction in 2 to 10
weeks. - The Mantoux test is performed by injecting 5
units of purified protein derivative (PPD)
intradermally into the volar or dorsal surface of
the forearm. If the person is infected a
characteristic welt will form.
106Tuberculin Skin Test, cont
- This welt consists of hardening in the form of a
raised bump where the PPD was placed and may be
red in color. The diameter of the induration is
measured to determine infection status. - The reaction to the Mantoux test should be read
by a trained healthcare worker 48 to 72 hours
after the injection. A negative reaction must be
read within 72 hours or the Mantoux test must be
repeated.
107Classification of Tuberculin Reaction
- There are three different classifications of
Tuberculin reactions. These vary based upon the
factors listed below - gt5 mm is positive for known or suspected HIV
patients, close contacts of persons with
infectious TB, persons with chest x-rays
suggestive of previous TB, and IV drug abusers. - gt10 mm - persons not listed above but are known
to be of populations at increased risk for having
TB. - gt15 mm is positive in persons with no known risk
factors.
108 Anergy
- Anergy occurs when the delayed hypersensitivity
reaction to the PPD test is absent or decreased
in individuals who are immunodeficient, i.e.
individuals with HIV, persons with severe febrile
illness, measles or Hodgkin's disease or those on
immunosuppressive drugs. Approximately one third
of patients with HIV infection and 60 of those
with AIDS may have skin reactions of lt5mm even
though they are infected with TB. - Individuals previously infected with TB may also
show a positive PPD test. A person's exposure
history and chest x-ray are also used to
determine infection, however a positive
bacteriologic culture is needed to confirm
diagnosis. Sputum collected for culture can be
produced by having the patient cough deeply so as
to ensure mucous is collected from diseased lung
tissue.
109Treatment of TB
- Tuberculosis disease can be effectively treated
using antibiotic therapy. Isoniazid and rifampin
are generally used, with pyrazinamide given for
the first two months. Ethambutol is added when
drug resistant bacilli are suspected. The length
of therapy and combination of antibiotics is
decided by the physician, based upon organism
antibiotic sensitivity, signs of improvement, and
patient compliance. - While on therapy, patients are monitored for side
effects that may be caused by the antibiotics.
Isoniazid (INH) has caused liver toxicity in some
patients. This occurrence is rare for people
under the age of 35, but has a somewhat greater
incidence for people over 35. Liver function
should be monitored in patients receiving
treatment with INH. Patients who are taking
ethambutol should be monitored for potential
visual changes.
110Treatment of TB, con't.
- It is especially important that patients complete
the prescribed drug therapy regimen in order to
effectively kill all bacilli. Drug-resistance can
develop when medications are taken incorrectly by
either skipping doses or not taking the
medication for the prescribed amount of time. - Directly Observed Therapy or DOT is used when it
is suspected that patients may not comply with
the prescribed treatment. DOT is accomplished by
designating a person to observe the patient
swallow each dose of medication.
111Preventive Therapy
- Individuals with positive PPD test results should
be evaluated for preventive therapy if they - are recent converters
- have close contact with TB patients
- have an immune deficient medical condition
- are HIV positive
- use IV drugs
- are lt35 years of age.
- Studies have shown that preventive therapy with
INH will reduce the risk of active TB by
approximately 70. Currently, INH taken by mouth
for 6 to 12 months is the recommended treatment
for preventive therapy.
112Infection Control
- The main goal of an infection control program is
to detect TB disease early and to isolate and
promptly treat persons who have TB. The infection
control program of any healthcare facility should
involve three types of controls administrative
controls isolation facilities and procedures
personal respiratory protection. - Administrative controls include risk assessment
development of TB infection-control plan
assignment of infection-control responsibilities
early identification, isolation, and treatment of
suspected cases.
113Risk Assessment
- At UNC, the TB Infection-Control Plan requires
that each healthcare facility and clinic area
must complete a risk assessment so that
appropriate infection control interventions can
be developed based on actual risk of TB
transmission. - The level of risk is based on
- the number or estimated number of TB infectious
patients admitted to each area - number of personnel PPD conversions
- and potential for patient transmission.
114Assignment of Responsibility
- The clinic director of each UNC facility is
responsible for assigning healthcare personnel to
implement infection control responsibilities.
115Early Identification of TB
- Early identification and isolation of patients
with TB is necessary to prevent TB transmission
among patients and personnel. Healthcare workers
who first come in contact with patients should be
trained to ask questions which will help identify
patients with active TB. Designated healthcare
professionals will evaluate patients immediately
so as to minimize time spent in waiting areas.
116TB Precautions for UNC Clinics
- TB precautions will be instituted for patients
suspected of having TB. Patients are instructed
to - wait in separate areas, apart from other
patients - wear surgical masks
- cover their mouths with facial tissues when
coughing or sneezing. - Persons suspected of having TB are referred to
either the Pulmonary Clinic or the Infectious
Disease Clinic where isolation facilities are
available for managing these patients. HIV
patients are sent to the Infectious Disease
Clinic.
117Isolation Facilities
- Patients with active TB are placed in isolation.
Engineering controls are used in each isolation
room to prevent the spread and reduce the
concentration of infectious droplet nuclei in the
air. - Isolation rooms are equipped with at least 6 air
exchanges per hour sufficient air distribution
within the room directional airflow from hallway
to room and direct exhaust of room air to
outside.
118Isolation Procedures
- Patients placed in TB isolation will be
instructed in procedures to prevent TB
transmission, and the reasons for their being
placed in isolation. - The door to the room must always be kept closed.
Healthcare workers will be instructed to wear
respirators. Patients who hav
