Which of the following is an example of an engineering control for bloodborne pathogen exposure prevention?
Answer: Safety-engineered needles with retractable shields
Safety-engineered sharps devices are engineering controls because they physically reduce exposure risk through device design rather than relying on worker behavior.
When using the RACE acronym for fire emergency response, what does the 'C' stand for?
Answer: Contain the fire by closing doors
In RACE (Rescue, Alarm, Contain, Extinguish/Evacuate), 'Contain' means closing doors and windows to slow fire spread and protect adjacent areas.
An N95 filtering facepiece respirator provides what minimum filtration efficiency against airborne particles?
Answer: 95%
The 'N95' designation means the respirator filters at least 95% of airborne particles that are not oil-based, as certified by NIOSH.
According to the chain of infection model, which link represents the location where a pathogen normally lives and multiplies?
Answer: Reservoir
The reservoir is the habitat in which an infectious agent normally lives and multiplies (e.g., humans, animals, soil, water, or medical devices).
Under 29 CFR 1910.134, employees required to wear a tight-fitting respirator must pass which evaluation before initial use?
Answer: Medical evaluation and fit test
OSHA's Respiratory Protection Standard requires both a medical evaluation (to ensure the worker can tolerate respirator use) and a fit test (to confirm an adequate seal) before tight-fitting respirators are used.
Which regulatory agency is responsible for approving and certifying respiratory protective equipment used in U.S. workplaces?
Answer: NIOSH
The National Institute for Occupational Safety and Health (NIOSH) tests and certifies all respiratory protective devices used in U.S. occupational settings.
