Which of the following should be managed as chemically hazardous Laboratory Waste?: A. Solid and liquid chemicals from lab processes B. Contaminated lab trash C. Clean broken glassware D. Unwanted stock chemicals E. Non-returnable gas cylinders F. Nitrile gloves with no visible contamination G. Rinse water from cleaning empty chemical containers H. A, B, D, E and G

The chemically hazardous Laboratory Waste should be managed as follows:

A. Solid and liquid chemicals from lab processes: These are chemically hazardous wastes as they may contain harmful substances. They should be disposed of according to the specific disposal procedures for each type of chemical.

B. Contaminated lab trash: This is also chemically hazardous waste. Any trash that has come into contact with chemicals can potentially be harmful and should be disposed of properly.

C. Clean broken glassware: This is not chemically hazardous waste. However, it can be physically hazardous and should be disposed of in a sharps container.

D. Unwanted stock chemicals: These are chemically hazardous wastes. Unwanted or expired chemicals can pose a risk to health and the environment and should be disposed of properly.

E. Non-returnable gas cylinders: These can be chemically hazardous waste if they contain any residual gas. They should be handled and disposed of according to the specific procedures for each type of gas.

F. Nitrile gloves with no visible contamination: These are not chemically hazardous waste. However, they are still waste and should be disposed of in a regular trash bin.

G. Rinse water from cleaning empty chemical containers: This can be chemically hazardous waste if the containers held harmful chemicals. The rinse water could contain traces of these chemicals and should be treated as hazardous waste.

H. A, B, D, E and G: This option includes all of the chemically hazardous wastes listed above. Therefore, it is the correct answer.
