Every chemical should be treated as though it were dangerous.
- Do not allow any solvent to come into contact with your skin.
- All chemicals should always be clearly labeled with the name of the substance, its concentration, the date it was received, and the name of the person responsible for it.
- Before removing any of the contents from a chemical bottle, read the label twice.
- Never take more chemicals from a bottle than you need for your work.
- Do not put unused chemicals back into their original container.
- Chemicals or other materials should never be taken out of the laboratory.
- Chemicals should never be mixed in sink drains.
- Flammable and volatile chemicals should only be used in a fume hood.
- If a chemical spill occurs, clean it up right away.
Ensure that all chemical waste is disposed of properly.
Chemistry lab safety rules
As chemistry labs are one of the most common types, these basic chemistry lab safety rules are relevant to many scientists, dealing with the safe performance of common activities and tasks in the average chemistry lab:
- Before you start an experiment, make sure you are fully aware of the hazards of the materials you'll be using.
- When refluxing, distilling, or transferring volatile liquids, always exercise extreme caution.
- Always pour chemicals from large containers to smaller ones.
- Never pour chemicals that have been used back into the stock container.
- Never tap flasks that are under vacuum.
- Chemicals should never be mixed, measured, or heated in front of your face.
- Water should not be poured into concentrated acid. Instead, pour acid slowly into water while stirring constantly. In many cases, mixing acid with water is exothermic.
