Types of chemical waste:

There are many types of chemical waste it may include solids, liquids, or gases containing or contaminated with any of the following, like (Acetone, Alcohols, and acetonitrile) flammable Solvents leachate toxic materials (heavy metals, Pesticides).

Name of chemicals in the laboratory:

Some are flammable liquids.

  • Acetone
  • Ethanol
  • Methanol
  • Ether Xylene, toluene
  • Ethyl acetate
  • Alcohol
  • Dimethylformamide
  • Benzene
  • Hexane, Pyridine, Pyrimidine Nitric acid, sodium hydroxide, Acetic acid
  • Con HCL etc.

Chemical waste Compatibility (1)

  1. Mineral acids- Plastic.
  2. Bases Plastic.
  3. Oxidizers – Glass.
  4. Organics (include Acetic acid)- Glass.

Chemical waste computability (2)

Take Special care

Niobic Acid:

  • Reacts with organics heat and gas.
  • Be sure the container is rinsed thoroughly.

Perchloric acid, Organic Peroxide:

  • Highly reactive with organics and organic material (wood) may react with metals.

Hydrofluoric acid:

  • Dissolves glass containers.

Segregate Chemical waste:

  1. Do not mix solids and liquids.
  2. Halogenated and non-halogenated chemicals.
  3. Proper segregation = good chemical hygiene + safe work Place environment.
  4. Chemicals do not store near each other.
Chemical Waste

  • Organics and acids
  • Powered or reactive metals
  • Mercury or silver and ammonium-containing Compounds

Classification of dangerous goods and Substances:

  • Class 1 Explosives
  • Class 2 Gases
  • Class 3 flammable liquids
  • Class 4 flammable solids
  • Class 5 Oxidizing and Organic Peroxides
