Study Notes
Risk Identification in Laboratories
- Laboratory workers face varied risks based on specific activities and analyses.
- Risk assessment is crucial for laboratory directors to ensure employee safety.
- Collaboration with safety officers assists in identifying potential hazards and implementing preventive measures.
- Development of safety procedures is essential for managing accidents, injuries, and contamination incidents.
- Maintain comprehensive records of staff exposures to hazards and actions taken to reduce future risks.
- A study by Howard Hughes Medical Institute highlighted physical risks and ongoing contamination and infection threats, including SARS-related laboratory-acquired infections.
Equipment and Safety Training
- Laboratory equipment carries significant injury risks, necessitating specific safety training.
- Key equipment requiring safety precautions includes autoclaves, centrifuges, compressed gas cylinders, and fume hoods.
- Risks of electrical shock, microwave exposure, or radiation arise from improper use or maintenance of lab instruments.
- Compressed gas storage requires careful handling; cylinders should be secured and safety caps used during transport.
Handling and Disposal of Sharps
- Proper handling and disposal of needles, broken glass, and sharp objects are crucial for preventing infection risks.
- Avoid recapping needles; if necessary, employ a specific safety technique.
- Dispose of sharps in puncture-resistant containers clearly labeled "SHARPS."
- Non-biohazardous sharps containers must have BIOHAZARD markings removed before sealing.
- Transport laboratory glass in sturdy boxes; contaminated glass must be decontaminated before disposal.
Chemical Exposure Risks
- Toxic chemical exposure can occur through inhalation, skin absorption, and ingestion, with inhalation being the primary route.
- Rapid absorption of solvents poses serious health risks.
- Skin condition can influence absorption rates; systemic poisoning may result from exposure.
- Accidental ingestion often occurs due to poor laboratory hygiene practices.
- Chemical labels must include common names, concentrations, hazard information, and dates of receipt/opening/expiration.
- Store hazardous chemicals appropriately; corrosive and toxic chemicals in ventilated areas, and flammables in secure cabinets.
Storage and Handling of Radioactive Materials
- Radioactive materials require special precautions and dedicated workbenches for safe use.
- Specific storage areas are necessary, employing protective materials such as plexiglass or lead.
Material Safety Data Sheets (MSDS)
- MSDS provide crucial safety and hazard information for chemicals, including product details, fire/explosion risks, toxicology, PPE recommendations, and waste disposal guidelines.
- MSDS must be easily accessible to employees and positioned near areas where hazardous materials are used.
Containment Systems in Laboratories
- Laboratory-acquired infections, primarily from aerosols, are prevalent in diagnostic settings.
- Containment systems are designed to prevent the diffusion of aerosols within and outside laboratory environments.
- Level 2 containment laboratories require adequate ventilation, whereas higher-level labs need continuous inward airflow and air filtration for safety.
