Laboratory safety Flashcards
Containment principles, technologies and practices that are implemented to prevent unintentional exposure to biological agents or their inadvertent release.
Laboratory safety
OSHA means
Occupational Safety and Health Administration
Enacted in 1970 – PL 91-596
Occupational Safety and Health Administration (OSHA)
The goal of this federal regulation body is to provide all employees with safe work environment.
OSHA
Provides written manuals that define specific safety policies and procedures for all potential hazards required in laboratories.
OSHA
Provide guidelines for developing these written policies and procedures are provided in several Clinical and Laboratory Standards Institute (CLSI) documents.
OSHA
[3] Primary standards
- Bloodborne pathogens
- Hazard Communication Standard
- Occupational Exposure to Hazardous Chemicals in Laboratories
Applies to all exposure to blood or other POTENTIALLY infectious materials.
Bloodborne pathogens
Mandates development of Control Plan.
Bloodborne pathogens
Proper decontamination and safe handling.
Bloodborne pathogens
HBV vaccine – 10 days before start working.
Bloodborne pathogens
Intended to ensure that hazards of all chemicals used in the workplace have evaluated.
Hazard Communication Standard
Development of SDS – Safety Data Sheet
Hazard Communication Standard
AKA OSHA Lab Standard.
Occupational Exposure to Hazardous Chemicals in Laboratories
Appointment of Chemical Hygiene Officer.
Occupational Exposure to Hazardous Chemicals in Laboratories
Development of Chemical Hygiene Plan.
Occupational Exposure to Hazardous Chemicals in Laboratories
A federal agency that carries out mandated public health laws and reporting requirements.
Center for Disease Control and Prevention (CDC)
Ensure quality healthcare for patients, prevent harm, and improve advocacy.
The Joint Commission (JC)
[3] Standard Precaution and Universal Precaution
- Universal precaution
- Body substance isolation guidelines
- Standard precautions
Formerly National Committee for Clinical Laboratory Standards (NCCLS).
CLSI
All patients are considered to be possible carriers of blood borne pathogens.
[standard and universal precaution]
Universal precaution
Wearing of Personal Protective Equipment when handling/collecting blood and bodily fluids contaminated with blood.
[standard and universal precaution]
Standard precaution
Consider all body fluids and moist body substances to be infectious.
[standard and universal precaution]
BSI guidelines
Combines major features of Universal Precautions and BSI Guidelines.
[standard and universal precaution]
Standard precaution
[7] types of HAZARD
- Biological
- Sharps
- Chemical
- Fire: NFPA
- Electrical
- Radiation
- Ergonomics
Any patient specimen or body substance is considered infectious.
Biologic hazard
Nosocomial Infection.
Biologic hazard
Infection acquired in healthcare.
Nosocomial infection
[3] Different kinds of Nosocomial infection
- Bacteria
- Virus
- Fungi
A continuous link in the transmission of harmful microorganisms between a source and a susceptible host.
Chain of infection
A specialized containment device designed to provide a safe working environment for laboratory personnel and to protect the external environment from exposure to potentially hazardous material.
Biosafety cabinet (BSC)
Process of eliminating or destroying all forms of microbial life, including bacteria, viruses, fungi, and spores.
[sterilization and disinfection]
Sterilization
The goal of this, is to render an object or surface completely free of viable microorganisms that could cause infection or contamination.
[sterilization and disinfection]
Sterilization
Involves the reduction of the number of pathogenic microorganisms on surfaces, instruments, or in the environment to a level that is considered safe for public health.
[sterilization and disinfection]
Disinfection
When exposed to HIV through accidental prick, etc.; within 72 hours
[PEP and PrEP]
PEP
Given only for individuals who have an active
sex life.
[PEP and PrEP]
