Biological and Physical Health Hazards

Biological Hazards

Biological hazards include bacteria, viruses, fungi, and other living organisms that can cause acute and chronic infections by entering the body either directly or through breaks in the skin.

Biological hazards are common in laboratories and clinics.

Occupations that deal with plants or animals or their products or with food and food processing may expose workers to biological hazards. Laboratory and medical personnel also can be exposed to biological hazards. Any occupations that result in contact with bodily fluids pose a risk to workers from biological hazards.

In occupations where animals are involved, biological hazards are dealt with by preventing and controlling diseases in the animal population as well as properly caring for and handling infected animals. Also, effective personal hygiene, particularly proper attention to minor cuts and scratches especially on the hands and forearms, helps keep worker risks to a minimum.

Workers who can be exposed to biological hazards should practice proper personal hygiene, particularly hand washing. Hospitals should provide ventilation, personal protective equipment, infectious waste disposal systems, and appropriate controls including isolation in instances of particularly contagious diseases such as tuberculosis.
