Precautions

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 commestibles 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

  • 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.
