1. MSDS = Material Safety Data Sheet
The MSDS lists the chemical ingredients of the substance.
Some list only the dangerous chemicals, while others list every ingredient, even if the chemical is not hazardous.
MSDS

2. The Purpose of a MSDS is to tell you….
Material’s Physical Properties
Health Hazard Data
Fire and Explosion Data
Reactivity Data
Spill & Leak Procedures
Special Protection Information & protective gear needed
Special Precautions / How to respond to accidents.
Company Info for phone # of emergency contacts

3. Who Supplies MSDS to Product Users?
All manufacturers of hazardous chemicals are required to provide one of these sheets for all products which they sell

4. Your Employee Rights & Student Rights
Your employer must have an MSDS for every hazardous substance that you use as part of your job
These MSDS’s must be available to you in the workplace
If you request to see a copy of an MSDS for a product you use and it is not provided in 1 working day, then you may refuse to work with the product in the area that it is used
If requested, your employer must provide a personal copy of an MSDS within 15 working days

5. Labeling and Marking Systems
All chemical containers must be labeled
Acceptable systems include
NFPA-704 diamonds (National Fire Protection Agency)
HMIS labels (Hazardous Materials Identification System)
Manufacturer’s original label
Other

6. Labeling and Marking Systems NFPA-704 Diamonds
Color coded &
numerical rating system
Provide at-a-glance hazard information

7. Labeling and Marking Systems NFPA-704 Diamonds
Blue = Health
Red = Flammability
Yellow = Reactivity
White = Special hazard information

8. Labeling and Marking Systems NFPA-704 Diamonds
4= Deadly Hazard
3= Severe Hazard
2= Moderate Hazard
1= Slight Hazard
0= No Hazard

10. HEALTH
4 Deadly: Slightest exposure to this substance would be life threatening. Only specialized protective clothing should be worn.
3 Extreme Danger: Serious injury from exposure to this substance. Do not expose any body surface to these materials. Follow full protective measures.
2 Dangerous: Exposure would be hazardous to health. Protective measures indicated.
1 Slight Hazard: irritation or minor injury would result from exposure to this substance. Protective measures are indicated.
0 No Hazard: exposure to this substance offers no significant risk to health.

11. FLAMMABILITY
4 Very Flammable, volatile or explosive depending on its state: Flash Point below 73ºF & Boiling Point below 100ºF. Extreme caution should be used in handling or storing of these materials.
3 Flammable, volatile or explosive under normal temperature conditions: Flash Point Below 100ºF. Exercise great caution in storage or handling.
2 Moderately heated conditions may ignite this substance: Flash Point Below 200ºF. Caution in handling.
1 Combustible, must be preheated to ignite: Flash Point Above 200ºF. Most combustible solids fit this category.
0 Will Not Burn

12. INSTABILITY
4 May Detonate: capable of detonation or explosion at normal temperatures and pressures. Evacuate area if exposed to heat or fire.
3 Explosive: capable of detonation or explosion by a strong initiating source, such as heat, shock or water. Monitor from behind explosion-resistant barriers.
2 Unstable: violent chemical changes are possible at normal or elevated temperatures and pressures. Potentially violent or explosive reaction may occur when mixed with water. Monitor from a safe distance.
1 Normally Stable: may become unstable at elevated temperatures and pressures or when mixed with water. Approach with caution.
0 Stable: remain stable when exposed to heat, pressure or water.

13. Labeling and Marking Systems HMIS Labels
Designed to go on individual containers of products that don’t have manufacturer’s labels
Same color code /numerical rating system as the NFPA diamonds

14. Labeling and Marking Systems HMIS Labels
Blue = Health
Red = Flammability
Yellow = Reactivity
White = Personal Protective Equipment or special protection information
Indicates numerical
Hazard Rating of 0-4

15. Chemical Hazard Communications
BE SAFE,
NOT SORRY!
