APPENDIX C

STORAGE GUIDELINES BY HAZARD CLASS

1.0

Caustics

Caustics are materials with pH > 10. Examples include ammonium hydroxide, calcium hydroxide,

and sodium hydroxide.

1.1

Separate from acids.

1.2

Store solutions of inorganic hydroxides in polyethylene containers.

1.3

Store large containers below eye level.

2.0

Acids

Acids are materials with pH < 5. Examples include acetic, chromic, and hydrofluoric.

2.1

Separate from bases and materials that could evolve toxic vapors on contact (i.e., sodium

cyanide).

2.2

Store large bottles low to the ground -- at least below eye level.

2.3

Separate inorganic acids from organic acids (i.e., acetic, oxalic, etc.).

2.4

Separate from active metals (i.e., sodium, potassium).

2.5

Store perchloric and nitric acid as oxidizers.

3.0

Flammables/Combustibles

Flammables/combustibles vapors ignite easily at room temperature. Examples include alcohols,

esters, ketones, ethers, and pyrophorics.
