There are three types of chemicals in the lab I was working; organic solvent, inorganic acid and organic acid. Because organic solvents are unstable and flammable, they are stored in the closed cabinet, which are away from heat and sunlight. Compared to organic solvent, inorganic and organic acids are stable. Thus, they are stored in a clear container and in see-through closet. Also, you should not store chemicals, which reacts to each other, together. Storing chemicals in proper containers and cabinets are essential for lab safety. Whenever you are working with a secondary container, be sure to label.
Never pour chemicals to sink. Chemicals must be drained to waste containers. In a solvent waste container, drain organic solvent and organic acid wastes. In an acid waste container, drain inorganic acid waste. If you are unsure about the chemical’s category, use an empty container and label it.
MSDS (Material Safety Data Sheet)
In MSDS, chemical properties, guidelines for handling, and emergency guidelines for every chemical in the lab are recorded. Before working with a new chemical, make sure that you read MSDS for particular chemical to work with it confidently and safely. In a case of an emergency, such as spill on the floor or on a person, supply emergency personnel with the MSDS of the spilled chemical.
