Study Notes
BIOSAFETY Overview
- BIOSAFETY refers to measures and protocols designed to protect humans, animals, and the environment from harmful biological agents, including pathogens and toxins.
BIOSAFETY LEVELS
- BIOSAFETY LEVELS (BSL) are categorized from BSL-1 to BSL-4, with BSL-1 being the lowest risk and BSL-4 representing the highest risk of dangerous pathogens.
- Each BSL level specifies different laboratory practices, safety equipment, and facility design requirements based on the organism's threat level.
Purpose of CONTAINMENT
- CONTAINMENT aims to prevent accidental exposure of laboratory personnel and the environment to potentially hazardous biological materials, ensuring safe handling and storage.
PRIMARY BARRIERS
- PRIMARY BARRIERS include physical barriers such as biological safety cabinets, gloves, and protective clothing that provide initial protection against biohazard exposure during laboratory procedures.
Role of SECONDARY BARRIERS
- SECONDARY BARRIERS are additional measures, such as controlled access to laboratory areas and waste decontamination systems, designed to provide an extra layer of safety and mitigate risks of accidental release into the environment.
BIOSAFETY LEVEL in Medicine
- In Medicine, BIOSAFETY LEVEL refers to the classification of laboratory risk associated with handling infectious agents, guiding safety measures and protocols.
Biological Safety Cabinet Purpose
- A biological safety cabinet protects researchers by maintaining a sterile environment, preventing the escape of aerosols and contaminants during the manipulation of infectious materials.
Personal Protective Equipment (PPE) Function
- PPE serves as a critical line of defense in infection control by providing physical protection against exposure to hazardous substances.
Universal Safety Precautions
- Laboratory personnel consider all specimens potentially infectious for HIV and other bloodborne infections to minimize the risk of transmission and ensure safety measures are uniformly applied.
Recommendations for Handling Specimens
- It is recommended that laboratory personnel use gloves and other protective measures when handling specimens that may come into contact with non-intact skin or mucous membranes to avoid exposure.
Standard Microbial Practices
- A key practice outlined in standard microbial practices for laboratory safety is to wash hands regularly and thoroughly, especially after handling cultures or potentially infectious materials.
Vaccination Against Hepatitis-B
- Laboratory personnel are advised to be vaccinated against Hepatitis-B as a preventive measure against potential exposure to bloodborne pathogens, enhancing their safety and wellbeing.
