Study Notes
Types of Hazards in the Laboratory
- Laboratory hazards can be categorized into different types: biological, chemical, radiation, electrical, fire, sharps and ergonomic.
Biological Hazard
- A biological hazard is a pathogen (disease-producing agent) that can be transmitted through various routes.
- Routes of transmission include direct contact (touching, biting, sexual intercourse), indirect contact (airborne, vector-borne, vehicle-borne (fomites, dust), and vertical transmission.
- Disposal of biological hazards requires specialized containers with a biohazard symbol.
- Decontamination methods vary by institution and can include incineration or autoclaving.
Sharps Hazard
- A sharps hazard includes needles, lancets, and broken glasswares.
Chemical Hazard
- A chemical hazard can be a solid, liquid or gas that can harm those exposed to it.
Radiation Hazard
- Radioactive materials are a hazard in clinical labs when performing procedures that use radioisotopes.
Electrical Hazard
- Electrical hazards can cause electric shock, burns, and fire.
Fire Hazard
- Any actions, materials, or conditions that might increase the size or severity of a fire, or that might cause a fire to start, are considered fire hazards.
- The acronym RACE (Rescue, Alarm, Contain, Extinguish or Evacuate) can be used to remember the steps to take in the event of a fire.
- The acronym PASS (Pull the pin, Aim, Squeeze, Sweep) are steps to remember when using a fire extinguisher.
Ergonomic Hazard
- Ergonomic hazards are a collection of injuries involving the musculoskeletal and/or nervous systems resulting from long-term repetitive twisting, bending, lifting, or maintaining static postures for extended periods.
