Study Notes
Biosafety and Standard Precautions
- Accessible to all employees for ongoing training, conducted annually.
- Exposure Control Plan emphasizes risks associated with bloodborne pathogens.
- Standard Precautions are essential to prevent transmission of infections.
Personal Protective Equipment (PPE)
- PPE includes gloves, fluid-resistant gowns, face shields, and safety goggles to minimize exposure.
- Employer provides necessary PPE and Hepatitis B vaccination.
Engineering Controls and Best Practices
- Engineering controls such as acrylic walls, disinfectants, sharps containers, and needle-free devices reduce exposure.
- Biological Safety Cabinets are critical for safe handling of pathogens.
Safe Work Practices
- Prohibits eating, drinking, or storing food in areas with samples or reagents.
- Regular disinfection of surfaces with a 10% Clorox solution is mandatory.
Incident Response Procedures
- Immediate action for incidents involves flooding wounds with water and cleaning with antiseptics.
- Report all incidents to a supervisor and seek medical help promptly.
Biological Hazards in Laboratories
- Laboratories face risks from various microorganisms, including bacteria, viruses, fungi, and parasites.
- Decontamination methods include sterilization via autoclaves and disinfection using chemicals like Clorox and alcohol.
Types of Precautions
- Body Substance Isolation (BSI) covers all body fluids and moisture.
- Blood Pathogen Standard (BBP) establishes guidelines for occupational exposure to HIV, HBV, and HCV.
Compliance with Regulations
- The need for ongoing hand hygiene, correct disposal of contaminated materials, and wearing appropriate PPE is emphasized by OSHA standards.
- Measures to break the chain of infection include frequent hand sanitization, glove use, and staying updated with immunizations.
Transmission Routes
- Direct contact, airborne, droplet, vehicle, and vector transmission highlighted as common pathways for infections.
Labeling and Safety Symbols
- Biosafety symbols indicate potential health risks, mandating preventive measures by workers.
Historical Development of Safety Regulations
- Timeline from 1970 to 2009 illustrates evolving regulations about infection control, isolation techniques, and the establishment of Standard Precautions.
- Key milestones include the introduction of Universal Precautions in 1985 and the mandatory BBP standard by OSHA in 1991.
Summary of Best Practices
- Emphasis on proper hygiene, the rationale for safty precautions in clinical settings, and absolute prohibition of food and personal activities in areas of potential contamination.
- Importance of keeping hands away from faces and maintaining cleanliness to prevent pathogen spread.
