Neumann College - Chemical Hygiene Plan

Appendix VI

Chemical Storage Compatibility

• Mineral acids, acetic and formic acids should be stored in trays in the designated areas in room 359.  Nitric acid is segregated from other acids. Perchoric acid is considered too dangerous to be in the chemical inventory.

• Bases are stored in trays in the ventilated storage cabinets in room 345.

• Flammable and combustible liquids are stored in the ventilated cabinets in room 345.

• Volatile toxics are stored in the ventilated cabinets in room 345.
