APPENDIX C

STORAGE GUIDELINES BY HAZARD CLASS

Instructor's Notes

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.
