How do I determine if a chemical is hazardous?

Ask your supervising adult and consult the Material Safety and Data Sheet (MSDS) for the chemical(s) you plan to use. Some MSDS sheets (e.g. Flinn), rank the degree of hazard associated with a chemical. Generally a rating more than 1 should be considered hazardous. It is possible that two or more chemicals ranked 0 or 1 when mixed can react and form a hazardous chemical.
