Characteristic Hazardous Waste

Ignitability

  • Liquid : Flash point of less than 140ºF or an aqueous solution containing 25% or more alcohol
    • Examples include acetone, methanol, turpentine, mineral spirits
  • Solid : Capable causing fire through friction, absorption of moisture or spontaneous chemical changes
    • Examples include sodium metal, white/red phosphorus
  • Gas : If the compressed gas meets the criteria in 40 CFR 261.21
    • Examples include acetylene and hydrogen
  • Oxidizer : If the material is an oxidizer (a compound that donates oxygen to a fire and increases its rate), it meets the Ignitability criteria
    • Examples include potassium nitrate, ammonium nitrate, potassium permanganate

Corrosivity

  • Aqueous liquids that are less than or equal to pH 2.5, or greater than or equal to pH 12.5 and all liquids that fail the Steel Corrosivity test are considered hazardous
    • Examples include concentrated acids (such as hydrochloric acid) and bases (such as sodium hydroxide)

Reactivity

  • A waste exhibits the characteristic of reactivity if it has any of the following properties:
    • Reacts violently with water
    • Forms potentially explosive mixtures with water
    • Generates toxic gases/fumes/vapors upon contact with water
    • Contains cyanide or sulfides that could generate toxic gases when exposed to certain pH conditions
    • Capable of detonate if heated under confinement or strongly initiated
    • Readily capable of detonation, explosive decomposition or reaction at standard temperature and pressure

Toxicity

  • If the waste contains the below listed contaminants at the concentration equal or in excess of the stated regulatory limits:
