Study Notes
Hazard Identification
- Essential signs in laboratories alert personnel to hazards and emergencies.
- Specific emergencies include fires and chemical spills that pose risks.
Safety Equipment
- Clinical laboratories must have safety showers, eyewash stations, and fire extinguishers.
- Equipment must undergo periodic testing and inspection for functionality.
- Mechanical pipetting devices are mandated for liquid manipulation to minimize risks.
Biological Safety
- Strict precautions are necessary when transporting and processing samples and body fluids.
- Personal protective equipment (PPE) like gloves, gowns, and face shields must be worn to prevent splashes.
- Specimens must be capped during centrifugation to avoid spills.
Spill Management
- Immediate cleanup procedures for any blood or potentially infectious material spills:
- Wear appropriate PPE.
- Use mechanical devices for broken glass or sharp objects.
- Absorb spills using proper materials such as towels or gauze pads.
- Clean and disinfect spill sites with approved disinfectants (e.g., 10% bleach).
- Dispose of materials in appropriate biohazard containers.
OSHA Standards
- OSHA mandates a written Exposure Control Plan to mitigate bloodborne pathogen risks.
- Categories of exposure:
- Category I: Daily exposure.
- Category II: Regular exposure.
- Category III: No exposure.
- Hepatitis B vaccinations must be offered at no cost to personnel in Categories I and II.
- Biological safety cabinets are crucial for handling infectious materials safely.
Toxic Chemical Safety
- OSHA's Hazard Communication Standard aims to reduce workplace chemically-related illnesses.
- Requirements include developing hazard communication programs and maintaining an inventory of hazardous substances.
- Employers must periodically update chemical inventories and communicate hazards effectively.
Chemical Communication
- Communication methods include labeling containers and posting hazard warnings.
- Training and informing employees about the employer’s chemical safety responsibilities are required.
- Material Safety Data Sheets (MSDS) must be available on site and detail each chemical's properties and effects.
NFPA Labeling System
- NFPA color-coded labeling system:
- Red: Flammability hazards.
- Blue: Health hazards.
- Yellow: Reactivity levels.
- White: Special considerations.
Laboratory Safety Rules
- Constant alertness is crucial for self-protection in laboratories.
- Staying informed and following instructions enhance safety.
Psychology of Safety
- Effective hazard control is vital for safe laboratory operations.
- Safety is achieved through:
- Common sense application.
- A safety-focused mindset.
- Good personal behavior and housekeeping.
- Continual refinement of laboratory techniques.
Accident Prevention
- Inexperience, neglecting known risks, carelessness, and fatigue can lead to accidents.
- Preventive strategies include:
- Conducting annual safety reviews.
- Performing safety drills.
- Fostering a culture of safety awareness.
Safety Awareness in Healthcare
- Healthcare organizations prioritize infection protection for employees against HBV and HIV.
- The CDC introduced Universal Precautions in 1987 for infection control.
- Blood and body fluid precautions are recommended for all patients, regardless of infection status.
- All blood and body fluids are treated as potentially infectious to ensure maximum safety.
