Instructor's Notes

3.0 Flammables/Combustibles

Flammables/combustibles vapors ignite easily at room temperature.

Examples include alcohols, esters, ketones, ethers, and pyrophorics.

3.1

Store flammable liquids in Underwriters Listed (UL) or

Factory Mutual (M) safety cans or cabinets.

3.2

Keep away from heat, sun, flame, and spark sources.

3.3

Separate from oxidizers.

3.4

Use only (UL) listed or FM approved "explosion safe" or

"spark-proof" refrigerators for cold storage of flammables.

4.0 Poisons (Toxics)

Poisons are dangerous if inhaled, swallowed, or absorbed through the

skin. Examples include phenol and hydrazine.

4.1

Store according to label directions.

4.2

Separate from other hazard classes.

4.3

Keep tightly sealed.

5.0 Oxidizers

Oxidizers are materials that yield oxygen: react with water, fire,

flammables, and combustibles. Examples include inorganic nitrates,

permanganates, inorganic peroxides, persulfates, and perchlorates.

Oxidizers must be stored in accordance with NFPA 45, Standard on

Fire Protection for Laboratories Using Chemicals and NFPA 430,

Code for the Storage of Liquid and Solid Oxidizers.
