Tissues fixed in Formalin
Separate the tissue from the Formalin solution. Tissue remnants dispose into the solid biological waste. Formalin should be disposed off as Chemical Waste.
Carcasses of experimental animals:
Carcasses of experimental animals should not be disposed off as biological waste. Bring the carcasses to the site designated by the Department of Veterinary Resources.
Ethidium Bromide Waste
Ethidium bromide solutions at concentration of less than 1µg/ml are not considered hazardous waste. The ministry of Environmental Protection approved the disposal of such solutions and gels to the regular waste. Any concentrated stock solution has to be disposed as chemical waste, carrying the appropriate Ethidium bromide waste label. These should be placed in the chemical waste area, from where it will be collected by the Safety Unit.
