(C) Safety Management Flashcards
What is the employee responsibility in safety?
Follow all safety rules and regulations; identify potential hazards in daily tasks.
What is the employers responsibility in safety?
Establish safe work practices; provide guidance, information, training, PPE, and medical surveillance; provide and maintain equipment and facilities free of recognized hazards.
Define incident.
A work-related event in which an injury or ill-health (regardless of severity) or fatality occurred or could have occurred.
Define Near Miss (aka close call).
An incident that could have caused serious injury or illness but did not.
What is the most effective to least effective in terms of safety controls?
Elimination > Substitution > Engineering Controls > Administrative Controls > PPE.
Define elimination control.
Removes hazard from workplace.
Define substitution controls.
Replaces hazard with something less hazardous.
Define Engineering Controls.
Physical setups or devices that reduce exposure.
Permanent changes to the work environment and controlling the hazard at the source are considered what type of safety control?
Engineering Controls.
Chemical Fume Hoods, Biological Safety Cabinets, Safe Sharps, Sharps Containers, Sound dampening materials, and adjustable height tables are all examples of what type of safety control?
Engineering Controls.
Define Administrative Controls.
Management strategies to reduce exposure.
Safety policies, chemical hygiene plan, and ergonomics programs are all examples of what type of safety control?
Administrative Controls.
Define Work Practice controls.
Procedures for safety and proper work that are used to reduce that duration, frequency, or intensity of exposure to a hazard.
Hand hygiene and decontamination are examples of what type of safety control?
Work Practice Controls.
___ is considered one of the most important steps in the control of infections.
Hand hygiene.
When should hands be washed?
After removing gloves, before leaving the lab, before and after contact with patients, immediately after accidental contact with blood or OPIM, and before eating.
What are the proper steps of hand washing?
(1) Wet hands with clean running water
(2) Apply soap
(3) Rub hands for 20 seconds
(4) Rinse under running water
(5) Dry hands with clean towel or air dry
(6) Use towel to turn off faucet
Define decontamination.
Removing or neutralizing contaminants on surfaces.
Define sterilization.
Destroys all forms of microbial life, including spores.
Define disinfection.
Destroys many or all pathogenic microorganisms, except bacterial spores, on inanimate objects.
What is the most common decontaminant used in the lab? At what dilution should it be used?
Household bleach; 1:10 dilution (10%).
Define PPE controls.
Protective gear needed to keep workers safe while performing their jobs.
___ is the LAST LINE of defense against exposure if other controls fail.
PPE.
Lab coats, disposable gloves, face shields/goggles, and respirators are all examples of what type of safety control?
PPE controls.
Define biohazardous waste.
Specimens and non-sharps supplies and materials contaminated (saturated) with blood or other potentially infectious materials (OPIM).
Define sharps.
Objects that can penetrate skin, such as needles, scalpels, broken glass, and capillary tubes.
Define contaminated sharps.
Sharps that have or may have blood or OPIM present.
Any facility that produces chemical waste must be registered with the ___.
EPA.
What are the characteristics of an Eye Wash station?
- <10 second walk from any location in the lab
- May be plumbed or self-contained
- Deliver 1.5 L per minute for >15 minutes
- Flow provided to eyes simultaneously
- Protected from airborne contaminants
- Once activated, flow should be hands free
- Tepid temperature
What are the characteristics of a Safety Shower station?
- <10 second walk from any location in the lab
- May be plumbed or self-contained
- Must operate for >15 minutes minimum
- Shower head must have a specific flow rate and pressure
- Produces a specific spray pattern
- Non-obstructed
___ is not considered cosmetic and is acceptable in a laboratory setting.
Hand crème.
Danger signs are to be posted…
where immediate hazard exists and special precautions are necessary.
Caution signs are to be posted…
where potential hazards as a warning against unsafe practices.
What colors are danger signs?
Red, black, and white.
What color are caution signs?
Yellow and black.
What color are safety instruction signs?
Green and white.
Within “clean” areas, removal of ___ and proper hand hygiene prior to entrance is needed.
PPE.
Define contaminated (“dirty”) areas.
The technical work area where all equipment/devices come into direct contact with infectious materials.
