What should I know when employed in a laboratory?
Consider blood and body fluids from all patients as infective. Refer to Routine Practices for preventing transmission of bloodborne infectious diseases.
Report immediately suspect fluid exposure, or a needlestick or sharp injury to a designated person or health care professional.
Please also see the OSH Answers document HIV/AIDS in the Workplace for more information.

Change gloves after processing specimen.
Wear gowns while working with potentially infectious material.
Wear masks and protective eye wear:
- if mucous membrane contact is likely

What precautions should I follow when working with needles and sharps?
- Use needles only when there is no alternative. Consider needles and sharp instruments as being infected.

- Do not recap, bend, break or remove needles by hand from disposable syringes or otherwise handle after use.
When should I decontaminate laboratory materials and surfaces?
Laboratory surfaces should be decontaminated:
- After a spill of blood or body fluid. Disinfect with a medical grade disinfectant.
