Segregation of Hazardous Waste - Chemical

Segregation of Hazardous Waste - Chemical

All hazardous materials should be stored and transported to prevent spills and uncontrolled reactions. Segregate chemicals by hazard class. Examples of proper segregation are:

  • Segregate acids from bases
  • Segregate oxidizers from organics
  • Segregate cyanides from acids.

Segregation of Incompatible Chemicals
Compatibility is important to consider in the handling, packed, storage, and disposal of chemical waste. Contact between incompatible substances can cause an adverse reaction. Examples of incompatible substances are as follows:

 

Chemical Keep out of contact with:

Acetic Acid

Chromic acid, nitric acid, hydroxyl compounds, ethylene glycol, perchloric acid, peroxides and permanganates

Acetylene

Chlorine, bromine, copper, fluorine, silver and mercury

Alkaline metals (e.g., powdered aluminum, magnesium, sodium, potassium)

Carbon tetrachloride or other chlorinated hydrocarbons, carbon dioxide and water

Ammonia

Mercury, chlorine, calcium hypochlorite, iodine, bromine and hydrofluoric acid

Ammonium nitrate

Special Segregation of Incompatible Chemicals
Dangerously incompatible substances, even in small quantities, should not be stored next to each other on shelves or in such a position that accidental rupture of containers may allow mixing. For example:

Chemical Keep out of contact with:

Chlorine

Acetylene

Chromic acid

Ethyl alcohol

Oxygen (compressed, liquefied)

Propane

Sodium

Chloroform and aqueous solutions

Nitrocellulose (wet, dry)

Phosphorous

Potassium permanganate

Sulfuric acid

Perchloric acid

Acetic acid

Sodium chlorate

Sulfur in bulk

Oxidizing agents are incompatible with reducing agents.
