Characterisitc Waste Codes
The majority of Hazardous Waste generated at Tennessee Tech. meet the criteria for Ignitability, Corrosivity, Reactivity, or Toxicity defined in TDEC Rule 1200-01-11-.02(3)(a-e) [40 CFR Part 261 Subpart C] making them a “Characteristic” Waste unless they are otherwise “listed” in the F, K, P, or U lists.
D001-Ignitability
A waste exhibits the Ignitability characteristic if it:
- Is a liquid, other than an aqueous solution containing less than 24 percent alcohol by volume and has flash point less than 60° C (140° F), (i.e. ether, tetrahydrofuran, mineral spirits, etc.)
- Is not a liquid and is capable, under standard temperature and pressure, of causing fire through friction, absorption of moisture or spontaneous chemical changes and, when ignited, burns so vigorously and persistently that it creates a hazard (i.e. sodium metal, aluminum carbide, sodium hydride, etc.),
- Is an ignitable compressed gas (i.e. hydrogen, acetylene, propane, etc.)
- Is an oxidizer or organic peroxide as determined by the United States Department of Transportation (DOT) 49 CFR 173.151 and 49 CFR 173.151a (i.e. ammonium nitrate, magnesium perchlorate,Benzoyl peroxide, etc.)
D002-Corrosivity
A waste exhibits the Corrosivity characteristic if it:
- Is aqueous and has a pH less than or equal to 2 or greater than or equal
to 12.5, - It is a liquid and corrodes steel at a rate greater than 6.35 mm
(0.250 inch) per year.
D003- Reactivity
A waste exhibits the Reactivity characteristic if it:
- Is normally unstable and readily undergoes violent change without detonating,
- Reacts violently with water,
- 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. - 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,
- Is capable of detonation or explosive reaction if it is subjected to a strong initiating source or if heated under confinement,
- Is readily capable of detonation or explosive decomposition or reaction at
standard temperature and pressure, - Is a forbidden explosive as defined in 49 CFR 173.51, or a Class A explosive as defined in 49 CFR 173.53 or a Class B explosive as defined in 49 CFR 173.88 (as those Federal regulations exist on the effective dateof these Rules).
