0400-12-01-.02(3)(d) Characteristic of Reactivity [40 CFR 261.23]

1. A solid waste exhibits the characteristic of reactivity if a representative sample of
the waste has any of the following properties:

(i) It is normally unstable and readily undergoes violent change without
detonating.

(ii) It reacts violently with water.

(iii) It forms potentially explosive mixtures with water.

(iv) 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.

(v) 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.

(vi) It is capable of detonation or explosive reaction if it is subjected to a strong
initiating source or if heated under confinement.

(vii) It is readily capable of detonation or explosive decomposition or reaction at
standard temperature and pressure.

(viii) It is a forbidden explosive as defined in 49 CFR 173.54, or is a Division
1.1, 1.2 or 1.3 explosive as defined in 49 CFR 173.50 and 173.53.

2. A solid waste that exhibits the characteristic of reactivity has the Hazardous
Waste Code of D003.
