Module 2: Laboratory Safety Flashcards
Six major categories of hazards
biological hazard chemical hazard electrical hazard fire hazard physical hazard ergonomic hazard
Enacted by the US congress and became basis for many countries in to providing all employees including laboratory personnel a safe work environment
Occupational safety and Health Act
The governing body responsible for ensuring and monitoring the implementation of the
standards set by the OSH Act
Occupational Safety and Health Administrtion
Key elements for safe operation of a clinical laboratory
- formal safety program
- documented policies
- identification kf hazards
- recognition of relevant safety areas of concern
Key important safety items in the laboratory
- proper clothing
- gloves
- eye protection
- eye washer or face washer
- chemical fume hood
Hazards that include all pathogen or disease-causing microorganisms
Biological hazards
Principle of Universal Precaution
treat all blood and blood contaminated sample as potentially infectious, but not pther bodily fluids not visibly contaminated
Principle of Standard precaution
Minimum practice applied to all patient care regardless of status of the patient including, hand hydpgiene, PPPE, cough etiquette, sharps safety, sterile instruments etc
