Corrosive Waste
(RCRA Code D002)

Corrosive sign

Corrosive Waste is an aqueous solution with pH less/equal to 2.0 or greater/equal to 12.5, or is a liquid and corrodes steel at a rate greater than 6.35 mm per year at at test temperature of 55 degree Celcius. While "acid" is low pH and "base" is high pH, not all corrosives are acids or bases.

Corrosive are found across a wide variety of chemical families:


  • Halogens (Bromine, Chlorines, Fluorine)

Inorganic Compounds

  • Acids: Hydrocloric, Sulfuric, Nitric, Phosphoric
  • Bases: Sodium and Potassium Hydroxides
  • Others: Hydrogen Peroxide, Hydrazine

Organic Compounds

  • Acetic Acid, Phenol

In case of spills....

For both acids and bases, use sodium bicarbonate i.e. baking soda

For Hydrofluoric acid, use calcium compond

  • Calcium Hydroxide (Slaked Lime)
  • Calcium Oxide (Lime)
  • Calcium Carbonate
  • Forms insoluble CaF2

Personal Protective Equipment (PPE)

  • Lab coat
  • Protective eyeware; usually splash goggles
  • Face Shields for larger volumes
  • Nitrile gloves for most application
  • Rubber/nitrile aprons for acid washing or handling larger volumes
  • Nitrile sleeves for hydrofluoric acid
  • No shorts, halter tops, or open-toed shoes
