5. Material Safety Data Sheets: Your Rights
1. Your school and even an employer must have MSDS information available for every hazardous substance you use as part of your job.

6. Material Safety Data Sheets: Your Rights
2. These MSDS sheets must be available to you the entire time you are in the laboratory or workplace.

7. Material Safety Data Sheets: Your Rights
3. If you request to see a copy of an MSDS for a product you use, and your employer cannot provide it after one working day, you may refuse to use that product or work in an area where it is being used.

8. Material Safety Data Sheets: Your Rights

Provide at-a-glance hazard information

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

12. Labeling and Marking Systems NFPA Diamonds
4= Deadly Hazard
3= Serious Hazard
2= Moderate Hazard
1= Slight Hazard
0= Minimal Hazard

13. Flammability 1 2 3 4 Example: water Example: corn oil
There is no fire hazard.
Example: water 1
Material must be pre-heated before ignition can occur.
Example: corn oil 2
Material must be heated for ignition.
Example: diesel fuel oil 3
A flammable liquid or solid which can be readily ignited.
Example: gasoline 4
A flammable vapor or gas which burns readily.
Example: propane gas

14. Health Hazard 1 2 3 4 Example: peanut oil Example: turpentine
There is no health hazard.
Example: peanut oil 1
The substance could cause irritation.
Example: turpentine 2
The substance could cause temporary incapacitation.
Example: ammonia gas 3
The substance could cause serious temporary or irreversible injury.
Example: chlorine gas 4
Material that on very short exposure could cause death or major residual injury.
Example: hydrogen cyanide

15. REACTIVITY 1 2 3 4 Example: liquid nitrogen
Material that in itself is normally stable,.
Example: liquid nitrogen 1
The substance may become unstable at high temperatures.
Example: phosphorus (red or white) 2
The substance is readily capable of non-explosive reaction.
Example: calcium metal 3
The substance may detonate when exposed to heat or an ignition source.
Example: fluorine gas 4
The substance is readily capable of detonation or explosive reaction.
Example: trinitrotoluene (TNT)
