After purchase and delivery, the chemical must be properly and safely used and handled in the lab. When not in use, containers are placed in storage for future application. Once the chemical has been used and is no longer in a form that can be used again, it must be disposed of according to federal, state, and local regulations. Each of these phases carries its own set of safety parameters. Information about these relevant guidelines can be found in the links below.
Chemical safety is closely related to laboratory safety and emergency procedures.
