General Principals
 No waste down the sink
 Store waste safely
 Do not dilute chemicals for
disposal
 Always label the chemical
waste-name description,
risk assessment number,
key hazards
 Do not mix waste types if
possible
 When in doubt ask
 Waste pathways should be
identified in the risk
assessment before any
waste is generated.

Hazardous Waste
Explosive, flammable liquids/solids, poisonous,
toxic, ecotoxic, infectious substances,
chemicals, clinical wastes; waste oils/water,
hydrocarbons/water mixtures, emulsions;
wastes from the production, formulation and
use of resins, latex, plasticizers,
glues/adhesives; wastes resulting from surface
treatment of metals and plastics copper, zinc,
cadmium, mercury, lead.
Liquids via chemical pathways
Polychlorinated biphenyls (PCBs)
Radioactive waste
At no stage should polychlorinated
biphenyls (PCBs) or other halogenated
compounds be mixed with other waste.
These require special disposal through the

Chemicals-Liquid Segregation
 Small quantities of chemicals may be combined for
waste disposal. (<200ml)
 Large qualities of waste should not be mixed but
stored and disposed of as unmixed waste to make
recycling easier. Chemical labeling rules apply to
waste.
 Waste is removed by the UNSW contractor
