Study Notes

Hazards in a Clinical Laboratory

Major categories of hazards: chemical, biological, physical, and ergonomic

Chemical Hazards

Examples: corrosive substances, flammable liquids, toxic compounds
Exposure can occur through inhalation, skin absorption, or ingestion

Biological Hazards

Include infectious agents such as bacteria, viruses, fungi, and parasites
Exposure can occur through cuts, puncture wounds, inhalation, or direct contact with infected tissues or bodily fluids
Essential to minimize exposure to minimize risk of infection
Examples of infectious agents: HIV, HBV, HCV, tuberculosis

Physical Hazards

Include electrical hazards, radiation exposure, and physical injuries
Exposure can occur through direct contact or proximity to hazardous equipment or situations

Ergonomic Hazards

Include repetitive strain injuries, musculoskeletal disorders, and eye strain
Exposure can occur through improper lifting, bending, or prolonged computer use

Laboratory Safety

Goal: to minimize risk of injury or illness to laboratory workers
Involves proper handling and disposal of hazardous materials, proper use of personal protective equipment, and adherence to safety protocols
