Chemical Hygiene Plan
Section 3.4 - Chemical Waste

G. Storage of Waste Chemicals

Waste Chemicals shall be stored in the same manner and using the same procedures as other chemicals. It may be advantageous to further segregate chemical waste. A typical segregation of waste chemicals would be:

• Acids
• Caustics
• Chlorinated Solvents
• Non-chlorinated Solvents
• Mercury Wastes
• Oxidizing Agents
• PCB Wastes*
• Reactive Chemicals*
• Waste Oil

• Wastes with Heavy Metal Contamination

*Consult with Environmental Health & Safety regarding proper storage and disposal requirements.

These chemicals shall be accumulated in separate containers and need to be isolated from one another to some degree, at least to the extent that spills or leaks would remain isolated from other containers. This is particularly true of acids, bases, and solvents.

Mineral (inorganic) acids, straight-chain fatty acids, and bases should be neutralized by the laboratory generating these wastes. Neutralization procedures may be found in Appendix D - "Neutralization of Spent Acids and Bases."

H. "Bulking" or Mixing of Waste Chemicals

Bulking or mixing of waste chemicals shall not be done without prior approval from OSU HAZMAT. Where permission has been granted by OSU HAZMAT, Standard Operating Procedures, found in Section 8.1 of this manual, are to be used as a guide.

I. Overpacking or "Boxing Up" of Multiple Chemical Containers

Laboratory personnel usually will not be involved in "boxing up" chemical containers inside overpack or boxes for transport, but where permission has been granted by OSU HAZMAT, Standard Operating Procedure will be found in Section 8.1 of this manual.
