In the laboratory
- Mark bottles of chemicals with a sticker and provide: name of the substance, date, name of the person responsible.
- Use bottles with a screw-cap whenever possible.
- Don't use recipients meant for comestibles to store chemicals.
- Keep bottles of chemicals as far away from the edge of your workplace as possible.
- Be careful while diluting acids and bases.
- Keep your supply of solvents at a bare minimum.
- Many volatile substances (especially solvents) form explosive mixtures in air, which accumulate on the ground, since they are more dense than air. Avoid open flames and ventilate.
- Glass doesn't belong in the normal trash cans (risk of injury for cleaning personnel).
- Don't carry large glass bottles by the neck or cap, instead hold them at the bottom.
- Don't use force on stuck ground glass joints. Use a piece of wood to gently knock on the joint, or slightly heat it.
