Different countries, states, localities, and institutions have different, often stringent, laws governing hazardous waste disposal. Failure to follow these laws can result in expensive cleanups, fines, and getting your ass fired. Check with your enviromental safety officer for a complete list of rules and a long boring lecture on how to properly dispose of hazardous waste. Usually this requires specially labeled containers and scheduled pickups. However, most of the rules can be generalized under a few guidelines which should always be kept in mind when dealing with chemical waste.
These materials should be disposed of in properly labeled liquid waste bottles.
Consult a list of chemical incompatibilities before adding a chemical to a waste bottle. Some incompatabilities are:
Chemicals which are reactive or pyrophoric can not be simply disposed of and must be quenched.
Some chemials are not particularly hazardous, but have unplesant odors. These should be destroyed before placing them in waste containers exposed to the laboratory enviroment. Some examples are:
When left exposed to the atmosphere for long periods of time, some chemicals form peroxides which can detonate when disturbed. Stocks of these chemicals should be periodiclly rotated. Some peroxide forming materials are:
