Safety Rating system for experiments. Important: This is a somewhat arbitrary rating system and is not meant to be a substitute for good judgment and lab experience. The ratings given are not absolute; certain factors can modify them either way. Some experiments are by nature more variable than others.
Low degree of overall hazard (toxicity, corrosiveness, flammability, etc), but accidents are still possible; you must still have basic lab skills.
Moderate hazards. Chemistry experience required.
Pronounced to Severe hazards.
Most severe hazards.
