Biological HazardsBiological Hazards

y These include bacteria, viruses, fungi, and other living organisms that cancause acute and chronic infections by entering the body either directly orthrough breaks in the skin. Occupations that deal with plants or animals ortheir products or with food and food processing may expose workers tobiological hazards. Laboratory and medical personnel also can be exposedto biological hazards. Any occupations that result in contact with bodilyfluids pose a risk to workers from biological hazards. In occupations where

animals are involved, biological hazards are dealt with by preventing andcontrolling diseases in the animal population as well as properly caring forand handling infected animals. Also, effective personal hygiene,particularly proper attention to minor cuts and scratches especially on thehands and forearms, helps keep worker risks to a minimum. Inoccupations where there is potential exposure to biological hazards,workers should practice proper personal hygiene, particularly hand

washing. Hospitals should provide proper ventilation, proper personalprotective equipment such as gloves and respirators, adequate infectiouswaste disposal systems, and appropriate controls including isolation ininstances of particularly contagious diseases such as tuberculosis.
