WARNING! Before you pour two different chemicals into your hazardous waste container YOU MUST CHECK TO MAKE SURE THAT THE WASTES ARE COMPATIBLE!!
There have been a number of laboratory accidents and explosions at colleges and universities in recent years that involved the mixing of incompatible chemicals that have resulted in personal injury and physical destruction. Some of these incidences occurred during experimental use while many other incidents involved the improper mixing of hazardous wastes.
Don’t Know? Don’t Do It! ASK if you are unsure if chemical wastes can be combined!
