Is it Characteristic?
Does the waste exhibit any of the following properties? If YES – it is hazardous waste.
Is it Ignitable?
- Liquids which have a flash point of less than 140°F (60.5°C)
- Flammable solids
- Flammable compressed gases
- Oxidizers/Peroxides
Is it Corrosive?
- pH ≤ 2
- Inorganic acids - digestion wastes, acid baths
- Organic acids - HPLC liquids, (formic, glacial acetic, trifluoroacetic)
- pH ≥ 12.5
- Bases/Alkalines - base baths
- hydroxides, lysis buffers
Is it Reactive?
- Compounds that are normally unstable and readily undergo violent change without detonation (diethyl zinc, organometallic substances)
- Compounds that react violently with water to liberate flammable or corrosive gases (anhydrous metal salts, alkali metals, metal hydrides, silanes)
- Cyanide and sulfides which can generate toxic gases, vapors, or fumes
- Compounds capable of detonation or explosion, either when initiated or due to decomposition or reaction at STP
