Each waste container bears a hazardous waste label that lists all chemicals in the container. EVERY PERSON using the waste container must neutralize their own waste before adding it to a container or we could have a reaction in the waste bottle causing pressure to build and the waste contents to geyser out of the bottle. o Solid Chemical Waste consists of all solid chemicals.
