Study Notes
Laboratory Safety
- Laboratory workers face various risks depending on their activities and analyses.
- Risk assessment is mandatory for laboratory directors to manage and reduce risks.
- Safety officers assist in identifying potential risks and implementing preventive measures.
- Emergency procedures should be outlined for accidents, injuries, and contamination.
- Records should be maintained for staff exposure to hazards, actions taken, and preventative measures.
Physical Risks in Laboratories
- A study by the Howard Hughes Medical Institute identified common physical risks.
- Personnel contamination and infection are also significant risks, even in high-containment facilities.
- Laboratory equipment is a primary source of potential injury.
- Training on safety procedures for equipment like autoclaves, centrifuges, compressed gas cylinders, and fume hoods is crucial.
- Electrical shock, microwave emissions, and radiation are also hazards.
Compressed Gas Safety
- Proper storage and handling of compressed gases are vital due to their unusual containers and high pressures.
- Cylinders must be chained to the wall to prevent falls.
- Safety caps should always be secured over the valve when moving or taking a gas cylinder out of service.
Sharps Disposal
- Needles, broken glass, and other sharps require careful handling and disposal to prevent infections.
- Needle recapping is discouraged but, if necessary, should be done with a one-handed technique.
- Sharps should be placed in puncture-resistant and leak-proof containers labeled "SHARPS."
- Non-biohazardous sharps should have their biohazard markings defaced before sealing the container.
Laboratory Glass and Plastic Ware Disposal
- Laboratory glass and plastic ware are not considered sharps but require different handling due to their potential to puncture regular waste bags.
- Sturdy cardboard boxes are needed for safe transport of laboratory glass.
- Boxes should be strong, no larger than 40 pounds when full, and not used for sharps, biohazardous materials, liquids, chemical contamination, or chemical containers.
- Contaminated laboratory glass must be decontaminated before disposal.
Chemical Safety
- Exposure to toxic chemicals poses a health and safety threat to laboratory staff.
- Inhalation, skin absorption, and ingestion are the main routes of entry for chemicals.
- Chemicals should be appropriately labeled with common names, concentrations, hazards, and additional information like date received, opened, and expiration.
- Proper storage is essential, separating corrosive, toxic, and reactive chemicals from ignitable substances.
- Radiochemicals require specific benches, covers, dedicated storage areas, and waste containers.
Material Safety Data Sheet (MSDS)
- MSDS is a technical document providing detailed hazard and precautionary information for chemicals.
- Businesses must distribute MSDS to customers for all chemicals they manufacture or distribute.
- Laboratories should follow MSDS guidelines to ensure safe handling and storage of chemicals.
- The MSDS provides information about the product, fire and explosion precautions, toxicology, health effects, personal protective equipment, storage recommendations, leak and spill procedures, waste disposal, and first aid.
Laboratory-Acquired Infections
- Laboratory-acquired infections are common in medical laboratories.
- Aerosols are the primary source of contamination, spreading over long distances.
- Containment systems focus on blocking aerosol diffusion in and outside laboratories.
- Ventilation is crucial for Level 2 laboratories, while higher containment laboratories require continuous inward airflow and absolute filtration of exhausted air.
