The document discusses personal protective equipment (PPE) and safety. It emphasizes that engineering and administrative controls should be used first before PPE. It notes that PPE must be properly selected based on a hazard assessment and worn correctly. The document outlines that training should cover when PPE is necessary, what type is required, how to properly wear and use PPE, limitations, and care and maintenance.

2.  Understand the hierarchy of safety
controls.
 Describe PPE required 100% of the time.
 Understand use and limitations of
commonly used PPE.
 Describe how to clean & store PPE.

4.  Bottom line:
 Hazard Assessment
▪ Exposure Monitoring
 Safety Data Sheets
 Engineering & work practice controls first

Health Effects

10. Adverse Health Effects
→ Adverse effects can range from minor
reversible effects to severe effects which are
irreversible.
Health Effects

11. Type of Health Effects
→ Acute Health Effects happen quickly, usually a
short time after exposure
→ Chronic Health Effects happen slowly over
time.

Routes of Entry

14. How Can Chemical Enter the Body?
Routes of Entry
In order for a chemical to become hazardous
to a person's health, it must first contact or
enter the body and the chemical must have
some biological effect on the body. There are
four primary Routes of Entry.

15. Inhalation
Routes of Entry
Inhalation may be the most common way in
which hazardous materials can enter your
body.
Dust, mist, fumes and vapors can be inhaled
in through your nose or mouth and travel
into your lungs where they can begin to
cause damage and even enter into your
blood stream.

16. Ingestion
Routes of Entry
Chemicals can easily be absorbed through
your digestive system.
This can occur if you have hazardous
materials on your hands while eating or
smoking.
It's also possible to swallow chemicals if food
is left uncovered in areas where there is a risk
of exposure to the chemicals.

17. Absorption
Routes of Entry
Some hazardous materials can also enter
your body by passing through your skin.
The severity of the harm also varies drastically
depending on what type of chemical has
contacted you.
Some hazardous materials will cause your
skin to become very sensitive, while others
may pass directly through the skin and into
the blood stream.

18. Injection
Routes of Entry
Chemicals can enter the body and particularly
the bloodstream through lacerations,
punctures or syringe needles.
