Acrylamide in its liquid or powder form is highly toxic by inhalation, skin absorption, and ingestion. It is a reproductive toxin and a carcinogen. Extra precautions must be taken when handling liquid and powder acrylamide. All waste must be disposed of via EH&S as hazardous waste.
Once acrylamide has been polymerized into a gel, it no longer poses a health threat and can safely be disposed of in the regular lab trash.
Ethidium bromide (EtBr) requires extra precautions during use and disposal because of its highly toxic and mutagenic properties.
All EtBr contaminated materials need to be disposed of as hazardous waste via EH&S. All waste containers must have a hazardous waste tag attached to them before hazardous waste is added.
There are three separate waste streams for EtBr:
Disposal of chemical containers depend on its CONTENT, the MATERIAL it is made of and container SIZE.
