  (PPE)

  you are required to wear.

5
What are Hazardous Materials?

• Hazardous Materials are chemicals that pose a
  health risk for
• People
• Our living environment
• Hazardous Materials are NOT
• Infectious waste
• Biological materials

6
The Three Forms of Chemicals

• Chemicals come in 3 forms
• Liquids
• Solids
• Gases
• Each department has a Chemical Inventory.
• Your Manager / Safety Coordinator will assist
• you in identifying
• The chemicals you may use at work
• Required Personal Protective Equipment (PPE)

7
Hazards

• Not all chemicals are
• harmful. It depends on
• whether they can cause
• harm when in use.
• The two types of
• hazards are
• Health
• Physical

8
Health Hazards

• Health hazards produce a
• direct effect on your health.
• Upon entering the body, the chemicals can be
  absorbed into the cells and blood stream.
• They may also cause damage to the cells upon
  actual contact to skin, eyes, or mucous
  membranes.

9
Routes of Entry

• There are four routes of entry into the human
• body by chemicals. These are

Ingestion (swallowing)
Inhalation (breathing in)
Injection (through sharp objects)
Absorption (through the skin)
10
Physical Hazards
Physical Hazards have an indirect effect on your
health. These chemicals cause physical reactions
that result in physical damage to our bodies.
Examples of physical hazards are

• Flammables
• Reactives
• Explosives

11
Effects of Chemical Exposure

• Acute exposures have an immediate effect.
• Exposure usually does not last a long time
  because pain or other symptoms cause us to react
• The effect can last a lifetime, e.g. corrosive
  burns
• Examples acid on skin or eye
• Chronic exposures have an effect over time.
• May result from one large exposure or many
  smaller exposures
• Examples Agents causing cancer or genetic changes

12
Exposure Prevention
Reduce a harmful chemical effect by

• Limiting Exposure
• Limit amount of time using chemicals.
• Use Personal Protective Equipment
• (PPE). It prevents the chemical from entering
  the body.
• Following safe work practices
• Use the correct chemicals.
• Follow procedures.
• Learning the hazards of the chemicals
• Read the Material Safety Data Sheet (MSDS).
• Read the label.

13
What are Material Safety Data Sheets (MSDS)?

• MSDS are written safety information on the
  chemical produced by the manufacturer.
• They contain information on safe use including
• Proper Personal Protective Equipment or PPE
• Exposure Limitations
• Health and Physical Hazards
• Spill response
• First Aid procedures
• Chemical components
• Find them on Providences Intranet. They are
  listed by location (department) and chemical name.

14
MSDS on the Intranet
MSDS are listed by Name Location

• MSDS is one of the Key Links on the Intranets
  Homepage.

15
Labeling

• All chemicals are labeled by the manufacturer.
• If a label contains the words
• Danger
• Caution
• Warning
• ... then the container holds a hazardous
  chemical.
• Do NOT deface or cover the original container
  label.
• Do NOT reuse the container.
• Dispose of the original container when it is
  empty.

16
Secondary Labels
If a chemical is transferred from an original
container to a new container, the new container
must be correctly labeled.

• Use a Providence approved
• secondary label.
• Include the chemical name
• List hazards
• Place a color in the in the Stop sign to indicate
  the degree of danger. Red is high hazard. Yellow
  is moderately hazardous and Green is low hazard.

17
Personal Protective Equipment (PPE)
Personal Protective Equipment (PPE) puts a
barrier between the human body and the hazardous
chemical.

• PPE is specialized to the task.
• PPE includes
• Gloves
• Goggles
• Safety Glasses
• Respirators
• PPE use is NOT optional. When indicated by the
  procedure, it must be worn.

18
Chemical Storage

• Store chemicals in an appropriate
• location by hazard class,
• not by alphabetical order.
• Flammables should be stored
• in a non-flammable storage
• container
• Do NOT store chemicals
• and food in the same place

19
Chemical Spills

• Small or medium spills can be cleaned up by the
  person using the chemical, if the employee
• Has been trained on how to cleanup the type of
  spill
• Knows the proper procedures for cleanup
• In the hospital, call a Code Orange for spills
  needing further assistance from outside the
  department. In the Satellites, a private vendor
  cleans-up/ disposes of large spills.

20
Chemical Waste

• Dispose of all waste in an appropriate manner.
• Deface the label when product container is empty
  and ready for disposal.
• Triple rinse empty containers before disposing in
  trash.
• Do NOT reuse empty chemical containers for other
  uses.
• Follow guidelines for any remaining waste.
• Do not pour hazardous chemicals down the sink
  without checking with your Manager or Safety
  Department Coordinator.
• Contact the Safety Department for proper disposal
  of chemical spill cleanup material.

21
Training

• Employees must be trained on
• Hazards and health effects of the
  chemicals they use
• Location of these chemicals MSDS
• Proper fit of some forms of PPE,
• e.g., N95 Masks
• Proper use of PPE
• Proper chemical waste disposal
• Secondary labeling
• Please talk with your supervisor
• or Safety Coordinator if you have
• any questions.

22
Key Point Summary

• Know whats on the Chemical Inventory for your
  area.
• It should be updated annually

  retail store. MSDS may not be available.
• Know how to access MSDS information (notebook or
  Intranet)
• Always use the right PPE. Report any broken /
  missing PPE.
• Follow all manufacturer instructions on safe use.
• Do not deface manufacturer labels. Use Providence
  labels on secondary containers.
• Store chemicals in designated locations.
• Store by hazard category, not by alphabetical
  order.
