Standards that regulate safety in the laboratory:
(There are 7)
Bloodborne Pathogen Standard
Formaldehyde Standard
Laboratory Standard
Hazard Communication Standard
Respiratory Protection Standard
Air Contaminants Standard
Personal Protective Equipment Standard
must be placed in all workplaces setting.
how communication works in response to a hazard.
Hazard Communication Standard
non-profit educational organization that sets voluntary consensus standards for all areas of clinical laboratories.
provides excellent general laboratory safety and infection control guidelines.
makes detailed step-by-step laboratory procedures as compared to OSHA.
CLSI
Standard System for the Identification of the Fire Hazards of Materials.

SPECIFIC HAZARD
the temperature wherein a material or reagent evaporates to form an ignition
FLASH POINT
TAKE NOTE LANG:
The lower the flash point, the more dangerous it is. The higher the number, the more dangerous the reagent is
federal agency that carries out mandated public health laws and reporting requirements. more on the workers, instead of the hazard
CDC
The three (3) standards under the CDC
UNIVERSAL PRECAUTIONS
BODY SUBSTANCE ISOLATION GUIDELINES
STANDARD PRECAUTIONS
1987
All are considered possible carriers of bloodborne pathogens.
the wearing of gloves when handling and collecting blood.
wearing face shields
doesn’t include urine and fluids not visibly contaminated with blood
UNIVERSAL PRECAUTIONS
Also protect the mucous membranes from splashes
FACE SHIELDS
are worn to protect the mucous membranes of the mouth, nose, and eyes from splashing of body substances
MASK AND GOGGLES
worn to protect against inhalation of droplets containing microorganisms from infective patients
MASKS
Worn to protect the clothing and skin of health- care workers from contamination by patient body substances and to prevent the transfer of microorganisms out of patient rooms
LABORATORY GOWN
Worn when user is in contact with blood or other potentially infectious materials
GLOVES
Wear __ when the patient interaction is assured of contact with blood or body fluids
PPE
Guidelines in Laboratory Settings:
From standard precautions ( CDC, 1996)
- Handwashing
- Gloves
- Mask, eye protection, face shield
- Gown
- Patient Care Equipment
- Environmental Control
- Linen
- Occupational Health
- Patient Placement
Development of policies regarding laboratory safety Accreditation of Clinical Laboratory
DOH
1996
Combines aspects of Universal Precautions and Body Substance Isolation Guidelines.
Treat all people as if they are infectious (patients)
STANDARD PRECAUTIONS
1987
Considers all body fluids and moist body substances to be potentially infectious.
Does not recommend handwashing after removal of gloves.
BODY SUBSTANCE ISOLATION GUIDELINES
TRANSMISSION-BASED PRECAUTIONS (CDC,1995)
AIRBORNE PRECAUTIONS
DROPLET PRECAUTIONS
CONTACT PRECAUTIONS
when microorganisms remain infective while being carried in the air or on dust particles.
can remain suspended in the air.
can determine through density.
AIRBORNE PRECAUTIONS
when microorganisms can be transmitted on moist particles produced during sneezing and coughing.
capable of travelling short distances.
DROPLET PRECAUTIONS
direct skin-to-skin contact or indirect contact with inanimate objects in patient’s room
CONTACT PRECAUTIONS
Requires all employers to have a written Bloodborne pathogen exposure control plan.

PORTAL OF EXIT
Means of infectious agent to reach a susceptible host
MEANS OR MODE OF TRANSMISSION
Means of an infectious agent to enter a susceptible host
PORTAL OF ENTRY
Patient or other healthcare worker (immunocompromised)
SUSCEPTIBLE HOST
An infection acquired by a patient during a hospital stay.
