(Sample management)

Laboratory waste

Process

Hazardous

Non-Hazardous

Chemical

Physical

Biological

Explosive/flammable

Causes Infections (e.g. pathogens, parasites)

Chemically unstable, reactive/corrosive

Causes cancer, mutations/birth defects

Toxic,damage the ecosystems/natural resources

Non-explosive or non-flammable

Does not cause infections (e.g. pathogens, parasites or their vectors)

Chemically stable, non-reactive or non-corrosive

Does not causes cancer, mutations or birth defects

Non-toxic, No damage to ecosystem/natural resources

Organic

Inorganic

Solvents

Acids, alkalis

Radioactive-eg. Iodine -125 (Radioisotopes used in research experiment )

Infectious- eg.Microbes (bacteria, virus; bodily fluid containing microbes)

Bio-hazard- eg. All bodily fluids are treated as potential hazards

Threat to human health or to the environment

Improves efficiency of using resources (less resources used, less waste generated) recycling methods of waste (if any)

Wastage of resource materials

Overall operational cost

1. Identification

Can be obtained by SDS and GHS

2. Segregation

Proper segregation = good chemical hygiene + safe workplace environment

3.Containment

4. Labeling of Wastes

5. Storage at Holding Area

6. Waste Treatment for Disposal
