A solid waste exhibits the characteristic of reactivity if a representative sample of the waste has any of the following properties: It is normally unstable and readily undergoes violent change without detonating; It reacts violently with water; It forms potentially explosive mixtures with water; When mixed with water, it generates toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment; It is a cyanide or sulfide bearing waste which, when exposed to pH conditions between 2 and 12.5, can generate toxic gases, vapors, or fumes in a quantity sufficient to present a danger to human health or the environment; It is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement; It is readily capable of detonation or explosive decomposition or reaction at standard temperature and pressure; It is a: Forbidden explosive as defined in 49 CFR §173.54; or Division 1.1, 1.2, or 1.3 explosive as defined in 49 CFR §173.50 and 173.53.
