Chemical Safety on the Job

2. We use many chemicals We want you to know how to use them safely.
You will learn about:
The Hazards of chemicals.
Our written program.
How chemicals are labeled.
Safe use of chemicals.
Material Safety Data Sheets
Basic procedures for spills.
Who you can ask for more information.

3. Hazards of Chemicals There are 2 basic types of chemical hazards:
Physical Hazards
Health Hazards
The first rule of Chemical safety is… "Know what you are working with and how to protect yourself and others.“

4. Physical Hazards
Chemicals are classified as having Physical Hazards if they are:
Explosive
Compressed Gas
Combustible Liquids
Flammable
Unstable
Water Reactive
Oxidizers

5. Physical Hazards
Some chemicals may be safe by themselves, but become dangerous when in contact with other substances.

6. Chemicals with Physical Hazards
Used only by trained employees.
Stored in a safe manner.
Never mixed with other chemicals unless by an approved procedure.

7. Health Hazards
Chemicals are classified as being a health hazard if they:
Can cause cancer.
Are poisonous (toxic).
Cause harm to your skin, internal organs, or nervous system.
Are corrosive - such as acids.
Cause allergic reactions after repeated exposure.

8. Ways Chemicals can enter the body
Your lungs if you breath fumes, mists or dust.
Your skin if liquid or dust touches or spills on you or splashes in your eyes.
Your mouth if you eat after handling chemicals.
Accidental swallowing of a chemical.

9. Health Effects
Some chemicals affect specific organs such as your kidneys, liver, reproductive or nervous system.

10. Our Written Hazard Communication Program provides
Written information on hazards.
Lists Chemicals we use and their hazards.
System for ensuring chemicals are labeled.
Means to ensure we have an Material Safety Data Sheet (MSDS) for each chemical.

11. Our Written Hazard Communication Program
Lists who is responsible for the program.
Provides chemical specific safety training methods.
Tells you where to find chemical safety information.
You can see a copy of our written program by asking you supervisor.

12. Labeling of Chemicals
Chemical Labels provide information on Identity, Hazards and Safe Use.
All chemical containers are labeled by the manufacturer.
Our company may place additional labels on the containers.

13. Labeling of Chemicals
If chemicals are placed in another container, this new container must have a label placed on it.
All containers must be properly labeled.

14. Uniform Labeling System
Our Company “Uniform Labels” are used to ensure we have one labeling system.
These may be placed on containers when chemicals are delivered to us or chemicals are transferred to other containers.

15. 2 Basic “Uniform Labels”
HMIS - Hazardous Material Identification System
NFPA - National Fire protection Association
Both types must identify the chemical name and hazards

16. Uniform Labels
Pictures may be used to identify hazards and required protection.
This Information may also be on the Manufacturer’s label.

17. HMIS & NFPA labels are very similar
Both use colored boxes to identify specific hazards.
Numbers or codes in the boxes tell you the hazard value - higher number = higher hazard.

18. NFPA & HMIS Label Colors
Red - Fire Hazard
Blue - Health Hazard
Yellow - Reactivity Hazard - explosive, unstable
White - Special Hazards - corrosive, radioactive, water reactive, acid

19. NFPA Label
The purpose of the NFPA 704 labeling system is to provide a way of quickly identifying the various fire related hazardous associated with a particular material. The NFPA 704 "diamond" is commonly found on bulk storage containers, but is also widely used on chemical containers and MSDS sheets.

20. NFPA Flammability Codes
4 Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and that will burn readily. Liquids with a flashpoint below 73ºF and a boiling point below 100ºF.

21. NFPA Flammability Codes
3 Liquids and solid that can be ignited under almost all ambient temperature conditions. Liquids with a flashpoint below 73ºF and a boiling point above 100ºF or liquids with a flashpoint above 73ºF but not exceeding 100ºF and a boiling point below 100ºF.

22. NFPA Flammability Codes
2 Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Liquids with flashpoint above 100ºF but not exceeding 200ºF.

23. NFPA Flammability Codes
1 Materials that must be preheated before ignition can occur. Liquids that have a flashpoint above 200ºF.
0 Materials that will not burn.

24. NFPA Health Hazard Codes
4 Materials that on very short exposure could cause death or major residual injury.
3 Materials that on short exposure could cause serious temporary or residual injury.

25. NFPA Health Hazard Codes
2 Materials that on intense or continued, but not chronic exposure could cause incapacitation or possible residual injury.

26. NFPA Health Hazard Codes
1 Materials that on exposure would cause irritation but only minor residual injury.
0 Materials that on exposure under fire conditions would offer no hazard beyond that of ordinary combustible material.

27. NFPA Reactivity Hazard Codes
4 Materials that in themselves are readily capable of detonation or of explosive decomposition or reaction at normal temperatures and pressures.

28. NFPA Reactivity Hazard Codes
3 Materials that in themselves are capable of detonation or explosive decomposition or reaction but require a strong initiating source or which must be heated under confinement before initiation or which react explosively with water.

29. NFPA Reactivity Hazard Codes
2 Materials that readily undergo violent chemical change at elevated temperatures and pressures or which react violently with water or which may form explosive mixtures with water.

30. NFPA Reactivity Codes
1 Materials that in themselves are normally stable, but which can become unstable at elevated temperatures and pressures.

31. NFPA Reactivity Codes
0 Materials that in themselves are normally stable, even under fire exposure conditions, and which are not reactive with water.

32. NFPA Special Hazard Codes
ACID = Acid Products
ALK = Alkali or Bases
COR = Corrosive Products
OX = Oxidizer
W =Reacts with water
Radioactive

33. What do I do Ff there is no label or I cannot read the label?
STOP - do not use the chemical.
TELL your supervisor.
READ the MSDS and have another label put on the container.

34. Chemicals can be safely used if
You know the hazards and how to protect yourself.
They are used only for approved purposes.
They are stored properly you use the correct personal protective equipment.
You do not eat in areas where chemicals are used.
You wash immediately if you come in contact with chemicals.

35. Chemical Disposal
Each chemical and container must be disposed of properly.
No container is truly "empty" unless properly cleaned.
Follow MSDS requirements for container disposal.
Recycle unused chemicals.
Do not place hazardous chemicals in normal trash receptacles.
Do not pour chemicals into sinks, onto the ground or in storm drains.

36. Safe Storage Store incompatible chemicals in separate areas.
Limit the amount of flammable material to the minimum needed.
Store flammable liquids in approved flammable storage lockers.
Store acids in separate flammable storage lockers.
Do not store chemicals in a refrigerator used for food storage.
Do not store food in refrigerators used for chemical storage.

37. In case of an emergency Implement the proper Emergency Action Plan.
Evacuate people from the area.
Isolate the area- keep other from entering.
Turn off ignition and heat sources.
Only trained employees are permitted to clean up spills.

38. Material Safety Data Sheets (MSDS)
