====== Ethidium bromide (EtBr) waste ======

Liquids containing EtBr must be treated with activated charcoal and then disposed of down the drain. 

If you use TBE (Tris-Borate-EDTA Buffer, borate is a CMR): 
  * treat it with activated charcoal to eliminate the EtBr, 
  * recover the borate buffer (without charcoal) in a can, 
  * dispose as chemical waste, indicating Borate on the can. 

If you have deposited a can of EtBr waste, please recover it and treat it appropriately.
