Study Notes

General Biosafety Guidelines

All employees must have access to training on biosafety practices annually.
Employers provide Personal Protective Equipment (PPE) and Hepatitis B Virus (HBV) immunization.
Standard practices include signs to identify risks and utilize specimen handling guides, including containers and sharp containers.

Exposure Control Methods

Standard Precautions protect against exposure to blood and other potentially infectious materials (OPIM).
PPE includes gloves, fluid-resistant gowns, full-face shields, and safety goggles.
Engineering controls minimize exposure through devices like acrylic walls, biological safety cabinets, and needle-free devices.
Safe work practices prohibit eating or drinking in work areas and using disinfectants like 10% Clorox to sanitize surfaces regularly.

Incident Response

Immediate response to incidents includes flooding wounds with water and cleaning with antiseptic.
Report all exposure incidents to a supervisor and seek immediate medical attention.

Biological Hazards

Risks extend beyond bloodborne pathogens to include bacteria, viruses, fungi, and parasites.
Decontamination methods include sterilization (e.g., autoclaves) and disinfection (e.g., using 70-90% alcohol or Clorox).
Antisepsis utilizes chemicals on skin to inhibit microbial growth.

Body Substance Isolation (BSI) and Bloodborne Pathogen (BBP) Standards

BSI focuses on precautions for all body fluids to prevent transmission of infections.
BBP standards emphasize the prevention of occupational exposure to HIV, HBV, and HCV, ideal for healthcare workers.

Key Components of Standard Precautions

Effective hand hygiene should be a regular practice to prevent pathogen spread.
Use correct disposal methods for contaminated materials and appropriate PPE based on fluid exposure.
Ensure mouth, nose, and eye protection with face shields and appropriate gowns.

Safe Practices Required by OSHA

Handwashing is the primary practice to prevent pathogen spread.
Prohibited activities in clinical lab areas include eating, drinking, smoking, or applying cosmetics.
Awareness of means of transmission (direct contact, airborne, droplet, vehicle, vector) is crucial.

Breaking the Chain of Infection

Regular hand sanitization, the use of gloves, current immunizations, and a healthy lifestyle help protect susceptible hosts such as patients and healthcare personnel.

Biosafety Symbol

A distinct symbol indicates risk or danger to health or the environment, emphasizing the necessity for exposure prevention measures.

Evolution of Safety Regulations and Guidelines

The CDC introduced isolation techniques for hospitals in 1970, with revisions through the years to adjust procedures for changing health threats.
The Bloodborne Pathogens Standard was enacted by OSHA in 1991, mandating Universal Precautions.
Significant guidelines from 2000-2009 include improvement acts on needle stick prevention and comprehensive hand hygiene protocols from WHO.

Summary of Historical Regulations

Initial focus on isolation techniques for infectious diseases in health settings expanded over the decades to include universal precautions aimed at protecting healthcare workers from blood and fluids.
