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.
The presence or absence of safety rating(s) does not absolve the reader of responsibility for safety, nor does it constitute a recommendation to do any particular experiment(s). Please review our Terms of Use.
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.
