Study Notes
Occupational Safety and Health Act (OSHA)
- Enacted in 1970 to ensure a safe work environment for all employees.
- Compliance checked through on-site inspections by state or federal agencies.
- Establishes safety standards applicable to clinical laboratories.
Bloodborne Pathogens
- OSHA mandates “Universal Precautions” for managing exposure to bloodborne pathogens.
- All blood and body fluids are considered potentially infectious.
- Requires an Exposure Control Plan to be documented in writing.
- Key pathogens include HIV, HBV, and HCV.
Exposure Categories
- Category 1: Daily exposure to blood and body fluids.
- Category 2: Regular exposure to blood and body fluids.
- Category 3: No exposure to blood and body fluids.
- Hepatitis B vaccination must be provided to personnel in Categories 1 and 2 at no cost.
Risk Reduction Measures
- Use engineering controls (e.g., work shields, pipeting devices) to minimize exposure risks.
- Personal protective equipment (PPE) must be provided by employers at no cost.
- Important PPE examples include gloves, masks, and gowns.
Good Work Practices
- Handwashing is critical before and after lab activities.
- Avoid mouth pipetting and consuming food or drink in the lab area.
- Needles should not be recapped, bent, or broken after use.
- Clean spills immediately with a 1:10 bleach solution and regularly clean workspace surfaces.
Biological Safety Cabinets
- Essential for safe manipulation of infectious materials.
- Must monitor airflow to prevent aerosol transmission of pathogens.
- Direct airflow design reduces exposure risk to lab personnel.
Hazardous Chemicals
- OSHA’s “Right to Know” standard grants employees access to information about hazardous chemicals.
- Chemical inventories and Material Safety Data Sheets (MSDS) must be maintained for all chemicals used.
- MSDS provide essential information on chemical risks and first aid measures.
Chemical Storage and Hygiene
- Chemicals should be stored according to National Fire Protection Association guidelines.
- Flammable solvents should be secured in flame cabinets.
- A Chemical Hygiene Plan outlines procedures for spills and requires adequate training.
Chemical Spills Response
- Contain spills, evacuate the area, and use emergency resources (eye wash, shower).
- Access MSDS and notify a supervisor following a spill.
Waste Disposal
- Hazardous waste can pose health or environmental threats when mishandled.
- Infectious and medical waste require special handling and labeling with biohazard symbols.
- Sharps containers must be puncture-proof and leak-proof.
Radiation Safety
- Caution and restricted access are essential around radioactive materials.
- Regular monitoring of equipment and employee exposure is necessary.
- Proper training on the safe handling of radioisotopes is mandated.
Fire Safety
- Fire requires a fuel source, ignition, oxygen, and a reaction chain.
- Fires classified into Classes A, B, C, and D based on their fuel types.
- Fire extinguishers should match the type of fire; NEVER use water on flammable or electrical fires.
Electrical Safety
- Lock out/tag out procedures must be followed for malfunctioning equipment.
- Report electrical shocks, replacing all frayed electrical wires and plugs.
- Emergency actions should prioritize safe disconnection of shocked individuals.
Other Hazards
- Cryogenic materials require specialized containers for safe handling under low temperatures.
