What You Need to Know

• The written hazard communication plan, chemical
  inventory, and MSDS for your department are in
  your supervisors office.

Other safety information is on the
world-wide-web. www.safety.uwm.edu/

Chemicals

• Question
• What must every chemical container have?

• Answer
• Label with chemical name
• Include appropriate hazards

7
Container Labels

• All chemicals (including solutions and chemicals
  transferred from their original containers)
  should be labeled with their common names,
  concentrations and hazards.

8
Container Labels

• Additional information such as date received,
  date opened, date of expiration should also be
  recorded.
• Label may also include Proper handling,
  storage, emergency response

9
Material Safety Data Sheets

• Every chemical you work with has a Material
  Safety Data Sheet.

10
Material Safety Data Sheets

• Use the MSDS in addition to the safety
  information on the label.

How do Chemicals Enter Your Body?
Inhalation
Ingestion
Skin Absorption
12
Skin Absorption

• Although skin is an effective barrier for many
  chemicals, it is a common route of exposure
• The toxicity of a chemical depends on the degree
  of absorption that occurs once it penetrates the
  skin.
• Once the skin is penetrated, the chemical enters
  the blood stream and is carried to all parts of
  the body.

Skin Absorption
13
Inhalation

• Inhalation is another route of chemical exposure
• Chemicals in the form of gases, mists, fumes and
  dusts entering through the nose of mouth can be
  absorbed through the mucous membranes of the
  nose, trachea, bronchi and lungs
• Unlike the skin, lung tissue is not a very
  protective barrier against the access of
  chemicals into the body

Inhalation
14
Ingestion

• Ingestion involves chemicals entering the body
  through the mouth. Chemical dusts, particles and
  mists may be inhaled through the mouth and
  swallowed.
• They may also enter through contaminated objects,
  such as hand or food that come in contact with
  the mouth
• This sort of exposure is generally accidental

Ingestion

Routes of Entry

• Routes of Entry for Husky
• Inhalation
• Skin

16
Acute and Chronic

• What is Acute?
• What is Chronic?

17
Acute and Chronic Health Hazards
Acute Acute health effects are characterized by
sudden and severe exposure and rapid absorption
of the substance. Normally, a single large
exposure is involved. Acute health effects are
often reversible. Examples carbon monoxide or
cyanide poisoning. Immediate ACUTE
CHRONIC Many Years Chronic Chronic
health effects are characterized by prolonged or
repeated exposures over many days, months or
years. Symptoms may not be immediately apparent.
Chronic health effects are often irreversible.
Examples lead or mercury poisoning, cancer.
18
Acute and Chronic Health Hazards

• Acute
• Are those whose effects occur immediately or soon
  after you come into contact with them.
• Immediate ACUTE

Many Years CHRONIC Chronic Are
those whose effects take years or decades to
occur after many exposures
19
Toxicity vs. Dose

• Dose is the AMOUNT of something you are
  exposed to or come in contact with.
• Less toxicity the greater the dose you can
  tolerate without ill effects.
• Greater toxicity the less dose you can tolerate
  without becoming sick.

Balance between toxicity and dose
20
Chemical Exposure Eyes

• Use thumb and forefinger to open eyelids to
  ensure effective washing behind eyelids
• Wash from nose out to ear to avoid washing
  chemicals back into eye or into an unaffected eye
• Continue to rinse for 15 minutes

21
Chemical Exposure

• Make sure you know the location of the nearest
  eyewash and safety shower

22
Personal Protective Equipment

• Wear approved Personal Protective Equipment (PPE)
  when handling chemicals
• Your supervisor should have PPE available and can
  assist with selection

23
Gloves

• Butyl
• Cotton
• Latex
• Leather
• Neoprene
• Nitrile
• PVC
• Rubber
• Viton
• Other

Be sure you know which glove is appropriate for
the chemical you are using
24
No Eating, Drinking or Smoking

• No eating, drinking or smoking anywhere chemicals
  are present

25
Hygiene

• Wash your hands thoroughly and frequently
  whenever working with chemicals

26
Hazard Placard

• What are the health hazards?
• What are the fire hazards?
• What are the reactivity hazards?
• Are there any special hazards?

27
Hazard Ratings

• 4 Severe Hazard
• 3 Serious Hazard
• 2 Moderate Hazard
• 1 Slight Hazard
• 0 Minimal Hazard

28
Hazard Placard HMIS System
29
Accident / Injury / Incident Reports

• Complete report within 24 hours of accident or
  injury
• Form must be reviewed and signed by your
  supervisor
• Initiates process for any Workers Compensation
  claim

30
Radioactive Materials

• Follow additional rules as described if you work
  with or work in an area with radiation or
  radioactive material.
