30CHAPTER 1 REVIEW and DISCUSSION
- If OSHA went away, what would companies do?
- Do Unions do much for Safety and Health anymore?
- What other regulation or movement have an impact
on safety and health besides OSHA? - What is next in the safety and health field?
- Review Questions
- 1. How did workplace tragedies affect the safety
movement? - 2. Explain the three Es of safety and how does
it apply to safety in the field? - Key Terms
- Assumption of Risk, Contributory Negligence,
Fellow Servant Rule
31Chapter 2 Accidents and their Effects
- According to National Safety Council
- During a 10 minute speech -- 2 persons will be
killed and about 170 will suffer a disabling
injury, costing 2,800,000. - On the average -- 11 accidental deaths and 1,030
disabling injuries every hour. - Occupationally 14 deaths a day
- Are Deaths at Work going up or down?
32DIRECT AND INDIRECT COSTS OF ACCIDENTS
- Direct Costs
- Lost wages
- Medical Expenses
- Insurance premiums administration
- Property damage
- Indirect Costs (Hidden and/or Uninsured Costs)
- Production loss
- Job -retraining
- Downtime and decreased production
- Costs of investigators time
- Overtime wages resulting from incident
33COSTS OF ACCIDENTS
- spent responding to accidents are that
could have been reinvested in technology,
research, facility upgrades etc. - Proactive vs. Reactive
- Why should WE prevent accidents?
- Economic reasons
- Moral reasons
- Legal reasons
34WORK-RELATEDNESS AND LOST TIME
- Not all accidents are work-related
- Bureau of Labor Statistics (BLS) website provides
work-related death/injury statistics - Lost time due to work injuries accounts for
approximately 35,000,000 hours/year! - Work-related fatalities and lost time injuries
must be recorded for OSHA and BLS. - INCIDENT RATE ?
- IR No. recordable injuries / illness X
200,000 - Total no. hrs worked by employees/year
35WORK INJURIES BY ACCIDENT TYPE
- from which the accident resulted, such as
- OVEREXERTION
- IMPACT INJURIES ( STRUCK-BY OR CAUGHT BETWEEN)
- FALLS
- According to the latest BLS report, what are the
two leading types of injuries?
36DEATH RATES BY INDUSTRY
- Agencies/ organizations which collect statistics
on fatalities include - 1. BLS - Bureau of Labor Statistics
- 2. NSC - National Safety Council
- 3. National Center for Health Statistics
- SIC codes - Standard Industry Classification
37PARTS OF BODY INJURED
- Important to keep records on the parts of the
body injured. Why? - Most frequent injured body parts include
- 1. Back
- 2. Legs and fingers
- 3. Arms
- 4. Trunk
- 5. Hands
38REPETITIVE STRESS INJURIES
- RSI - Repetitive Stress Injuries is a broad term
which includes injuries resulting from cumulative
trauma to the soft tissues - MSD - Musculoskeletal Disorders
- CTS - Carpal Tunnel Syndrome - common repetitive
stress injury to the wrist which effects the
median nerve.
39ESTIMATING COSTS OF ACCIDENTS
- Safety professionals must show COSTS of accidents
are greater than the COSTS of prevention. WHY? -
CBA - Look at both the INSURED AND UNINSURED (direct
and indirect) costs - Calculate the costs
- HOW DO YOU GET THE NUMBERS?
40CHAPTER 2 REVIEW AND DISCUSSION
- How does Lawsuits affect the reasons to increase
the safety? - If Company A has a IR of .7 and Company B has a
IR of 5.6, does that mean the Company A has a
better safety program? - Why is Company Cs IR of 2.5 better than
Companys D 1.3? - Review
- 1. What are some direct and indirect costs?
- 2. Why is it important for the Safety
Professional to estimate accident costs? - 3. How are incident rates calculated?
- Define the following ACRONYMS
- BLS, NSC, OSHA, MSD, SIC
41Chapter 3 THEORIES OF ACCIDENT CAUSATION
- DOMINO THEORY
- HUMAN FACTORS THEORY
- ACCIDENT INCIDENT
- SYSTEMS THEORY
- COMBINATION THEORY
- DRUGS, ALCOHOL, AND DEPRESSION
- MANAGEMENT FAILURE
42THE DOMINO THEORY
- 1920s - Herbert Heinrich, Travelers Insurance
- 88 caused by UNSAFE ACTS
- 10 caused by UNSAFE CONDITIONS
- 2 UNAVOIDABLE
- This has been proven false in many other
theories.
43HEINRICHS AXIOMS
- 1. Injuries result from series of factors, one is
the accident itself. - 2. Accident occurs only from an unsafe act by a
person and/or hazardous condition. - 3. Most accidents result from unsafe behavior.
- 4. Unsafe act does not always immediately result
in accident. - 5. Reason for unsafe act can guide correction
44AXIOMS CONT
- 6. Severity of accident is fortuitous and
accident is preventable - 7. Best accident prevention best quality
production techniques - 8. Management should assume responsibility for
safety. - 9. Supervisor is key in prevention
- 10. Accidents have direct and indirect costs.
455 DOMINOS
- 5 FACTORS in sequence lead to accident
- 1. Ancestry and social environment
- 2. Fault of person
- 3. Unsafe act/ Hazardous condition
- 4. Accident
- 5. Injury
46DOMINO THEORY - 2 POINTS
- 1. Injuries are caused by the action of preceding
factors - 2. The removal of the central factor (unsafe act
or hazardous condition) negates the action of the
preceding factors, thereby preventing accidents
and injuries. - How do you use this model to prevent accidents?
47HUMAN FACTORS THEORY
- Attributes accidents to chain of events
ultimately caused by human error. - 1. Overload
- Environmental factors
- Internal factors
- Situational factors
- 2. Inappropriate response
- 3. Inappropriate activities
48ACCIDENT/INCIDENT THEORY
- An extension of H.F. Theory
- Developed by Dan Petersen
- New elements ie. ergonomic traps
- Conscious or unconscious decision to err
- Causal relationship between management decision,
management behavior and safety. - MULTIPLE CAUSES
49SYSTEMS THEORY
- A system is a group of interrelated components
that interact together to form a whole. - Likelihood of an accident determined by how these
components interact. - Interacting components
- Machine
- Person
- Environment
50RISK DECISIONS
- 1. JOB REQUIREMENTS
- 2. WORKER ABILITY LIMITATION
- 3. GAIN IF TASK IS ACCOMPLISHED
- 4. LOSS IF ATTEMPTED TASK FAILS
- 5. LOSS IF TASK IS NOT ATTEMPTED
- What is you HAD to do a job that is extremely
high hazard?
51COMBINATION THEORY
- Cause of accident cannot be determined by one
model of theory - Combines parts of several different theory models
- Avoid the tendency to apply one model to all
accidents.
52OUTSIDE FACTORS
- Drugs, Alcohol, Depression, Family Issues
- Intent
- Management Failures
- How do each of these factors affect accident
theory?
53CHAPTER 3 REVIEW AND DISCUSSION
- How does the worker deal with POOR management?
- How does failure of management fit in the domino
theory or multiple cause theory? - REVIEW
- 1. List the 5 dominos in the Domino Theory of
Accident Causation. - 2. What is the main premise of the Domino Theory?
- 3. What is the main premise of the Multiple Cause
Theory?
54Chapter 4 - OSHAct, Standards and Liability
- OSHAct Rationale
- Mission and Purpose
- Coverage
- OSHA Standards
- Recordkeeping Reporting
- Workplace Inspections
- Citations and Penalties
- State OSHA Programs
- OSHAs Services
- Employer and Employee Rights Responsibilities
- OSHA Standards
55Rationale for OSHAct
- A comprehensive, uniform law was needed to help
reduce work-related injuries, illnesses and
deaths. - Average of 14,000 deaths per year
- 2.5 million disabled workers from accidents each
year - 300,000 new cases of occupational disease each
year. - The OSHAct is contained in Title 29 of the Code
of Federal Regulations ( 29 CFR) - General Industry - Parts 1900 1910
- Construction - Part 1926
- Maritime - Part 1915
56OSHActs Purpose
- To assure so far as possible every working man
and women in the nation safe and healthful
working conditions and preserve our human
resources.
57OSHAs Mission Purpose
- Reduce workplace hazards
- Implement new safety health programs
- Improve existing H S programs
- Establish rights of employers and employees
regarding workplace safety health - Monitor job-related illnesses injuries
58OSHAs Mission Purpose
- Establish training programs to increase safety
health professionals improve competency - Establish mandatory workplace safety and health
standards - Provide for state-level programs
- Monitor evaluate statelevel programs
59OSHAct Coverage
- Covers employers in all 50 States , District of
Columbia, Puerto Rico, and all other U.S.
Territories. - If employer has 1 employee, it must comply with
applicable sections of the Act. - Sometimes this is very confusing -- Reporting VS.
Coverage.
60Exemptions
- Self-employed
- Family farms that employ immediate members of
family - Federal agencies covered by other federal
statutes - State and local governments
- Coal mines (MSHA)
61OSHA Standards
- Some standards apply to specific types of
employers ie. Process Safety Management
(Vertical) - Some standards apply to all employers (with some
exemptions) ie. Hazcom (Horizontal) - Horizontal and Vertical
- Performance and Specification
- General Duty Clause requires that employers
provide a workplace that is free from hazards
that are likely to harm employees. - When is the General Duty Clause used? Public Law
5(a)1
62OSHA Standards
- Most OSHA standards came from consensus standards
ie. NFPA and ANSI - Requests also come from other federal agencies,
standard setting agencies or labor organizations
and private citizens. - Standing committee or Ad Hoc Committees
- NACOSH- National Advisory Committee on OSH
- NIOSH National Institute for OSH
63Standards vs. Regulations
- OSHA issues both standards and regulations
- Standards address specific hazards ie. Confined
spaces - Regulations can be generic in some cases or more
specific in others. - Regulations do NOT apply to specific hazards and
do NOT require the rigorous review process that
the standards go through
64OSHA Standards
- OSHA can adopt, amend or revise standards
- First must publish a Notice of Proposed
Rulemaking in the Federal Register - Next, OSHA conducts a public hearing ( if one is
requested) comments are voiced - After comment period and public hearing, final
amended text of standard is published in the
Federal Register with explanations.
65Code of Federal Regulations
- Title 29 contains all standards assigned to OSHA
- Title 29 is divided into several PARTS
- PART 1910 General Industry Standards
- PART 1926 Construction Industry
- PART 1915 Maritime
- Part 1910 consists of 21 SUBPARTS
- Subparts are denoted by uppercase letters
- PARTS are also divided into SECTIONS ie. 29 CFR
1910.1200 Hazard Communications
66Code of Federal Regulations
- The SECTIONS are divided into 4 levels of
SUBSECTIONS - 29 CFR 1910.1200 (a) (1) ( iv) (C
- 1st level lower case alphabet
- 2nd level Arabic numerals
- 3rd level Lower case Roman numeral
- 4th level Uppercase letters
67Temporary Emergency Standards
- OSHA is empowered to issue a TES as an interim
measure until a permanent standard can be
developed. - OSHA must determine
- Workers are in imminent danger to a hazard which
is not covered by existing standard - ETS must be published in the Federal Register
68TEMPORARY VARIANCE
- If employer is not able to comply with a new
standard by its enforcement date, employers may
file for a TEMPORARY VARIANCE - Temporary variance can be granted up to a maximum
of ONE YEAR AND - The employer must demonstrate they are making
effort to comply.
69PERMANENT VARIANCE
- Employers may apply for PERMANENT VARIANCE if
they can demonstrate that they already EXCEED the
requirements of the new standard. - Employees must be informed and allowed to have a
hearing - OSHA has the authority to award or deny.
70OTHER VARIANCES
- EXPERIMENTAL VARIANCE May be awarded to an
employer participating in OSHA sponsored
experiments to test effectiveness of new health
and safety procedures. - Variances may also be awarded when in the best
interest of the countrys national defense.
71RECORDKEEPING AND REPORTING
- 29 CFR 1904 provides OSHAs requirement for
injury/illness occupational recordkeeping. - Recent changes have been made to improve this
process. - OSHA log and summary form 200 changed to form 300
- OSHA form 101 changed to form 301
72RECORDKEEPING REPORTING
- OSHA requires reporting injury/illness resulting
in one of more of the following - Death of 1 or more workers
- One or more days away from work
- Restricted duty or transfer to another job
- Loss of consciousness
- Medical treatment beyond first aid
73RECORDKEEPING EXCEPTIONS
- Employers with 10 or fewer employees (full or
part-time in any combination) - Employers in the following categories
- Real Estate
- Finance
- Retail trade
- Insurance
- Some SICs are exempt except for fatalities or 5
or more hospitalizations
74EMPLOYEE INFORMATION
- OSHAct requires employees to be informed of
specific items. - OSHA Poster 2203 explains rights and
responsibilities - Summaries of all variances
- Copies of citations
- OSHA Log and Summary of Injuries and Illnesses
(300 Form) post February 1 to April 30 annually. - Employee access to medical and exposure
monitoring records.
75OSHA Inspections and Enforcement
- Inspections
- Imminent danger situations
- Fatal accidents

have been reasonable foreseen.
77CHAPTER 4 REVIEW and DISCUSSION
- What are the problems, issues with OSHAct and
OSHA? - Why do some employers still not comply with OSHA?
- Why do employers spend time trying to find
loopholes instead of just correcting the problem?
- Why are there so many companies that fail to
report all of the accidents? - What are companies worried about OSHA or
Lawsuits? - REVIEW

78Chapter 5 - Workers Compensation
- Form of social insurance No fault insurance
- Prior to WC the English Common Law allowed
recovery only when the employer was solely
negligent and only after suits were brought for
damages. - Today, most state require WC as the exclusion
remedy for job-related injuries. - All 50 states have WC laws.
- OSHA Recordkeeping VS. WC
79Workers Compensation - Common Elements
- Victims receive prompt, reasonable and certain
income and medical benefits without litigation. - Negligence and fault are immaterial NO FAULT
INSURANCE - Appeals process exists to resolve disputes
- Benefits are predetermined.
- The system includes rehabilitation
- Enforcement penalties apply to employers who do
not pay benefits.
80Common Elements cont
- Objectives of WC
- Replacement of Income
- Rehabilitation of the injured employee
- Prevention of Accidents (Lower Premiums)
- Cost Allocation (Spread cost out)
- Most states set max benefit at 2/3 of the state
average wages, but some use 100 - Benefits are tax free.
81State WC Funds
- Insurance Companies owned and operated by the
state. - In Texas this is called The Texas Workers
Compensation Insurance Facility. - Covers employers who are unable to get private
insurance. - Type of State Fund
- Monopolistic - State is the only insurer
- Competitive - State sells insurance alongside
the private carriers - Texas is a competitive state fund.
- Self-Insurance
- Self-insurance allows the company to manage its
own cases and cash flow rather than contributing
to an outside company with the associated cost
burden to do it. - Texas allows self-insurance.
82Benefits
- Income benefits - Lifetime loss 75 of avg.
weekly wage for life. - Medical benefits
- Vocational rehab
- Death benefits - Not more than 2500 burial, 75
of the deceased average weekly wage.
83Disability Classifications
- Permanent Total - 100 disabling such as spinal
cord injury - Temporary Total - back surgery with full
recovery - Permanent Partial - amputation which cannot
fully recover from - Temporary Partial - broken leg allows to perform
only partial duties
84Texas WC Benefits
- Temporary - 104 weeks of benefits
- Impairment - Permanent damage - 300 weeks of
benefits - Supplemental - Permanent damage benefits after
impairment - 401 weeks of benefits
85Other elements of Texas WC
- must notify employer within 30 days of injury or
knowing about an illness. - must file a claim for compensation within 1 year
- Insurer not liable for an injury if the person is
in a state of intoxication or using a controlled
substance. - This is why there are drug tests after injuries.
