A safety officer discovers that the hospital's oxygen storage room lacks proper ventilation. Using the bow-tie model, where would 'inadequate ventilation' be classified?
Answer: Escalation factor
In the bow-tie model, an escalation factor is a condition that weakens a preventive barrier, making the top event more likely — inadequate ventilation undermines the ventilation control.
Which OSHA standard specifically requires healthcare employers to conduct annual exposure determinations and update their Exposure Control Plan?
Answer: 29 CFR 1910.1030 (Bloodborne Pathogens)
29 CFR 1910.1030 mandates annual review and update of the Exposure Control Plan to reflect changes in tasks, procedures, and available safer devices.
A root cause analysis team uses a fishbone (Ishikawa) diagram after a patient fall. The categories typically examined include all of the following EXCEPT:
Answer: Market share
Market share is a business metric, not one of the classic 6M fishbone categories (Man, Machine, Method, Material, Measurement, Mother Nature/Environment).
A hospital's environmental health and safety department is assessing chemical hazards in the lab using NFPA 704 diamond ratings. What does the BLUE section of the diamond indicate?
Answer: Health hazard
The blue (left) section of the NFPA 704 diamond indicates health hazard, rated 0–4 based on the degree of acute health risk.
When assessing ergonomic hazards for surgical technologists who stand for prolonged periods, which control is an example of an ENGINEERING control rather than an administrative control?
Answer: Providing anti-fatigue matting at the surgical table
Anti-fatigue matting is a physical modification to the workstation (engineering control), while rotation schedules, breaks, and training are administrative controls.
A healthcare safety professional is conducting a quantitative fit test for N95 respirators. Which method measures aerosol concentration inside and outside the mask to calculate a fit factor?
Answer: OSHA ambient aerosol condensation nuclei counter (CNC) method
The OSHA-accepted ambient aerosol CNC method (PortaCount) is a quantitative fit test that measures particle counts inside vs. outside the facepiece to generate a numerical fit factor.
A hospital safety committee wants to reduce the risk of workplace violence in the emergency department. Which approach best exemplifies a COMBINATION of engineering and administrative controls working together?
Answer: Installing panic buttons at triage desks AND training staff on de-escalation techniques
Panic buttons (engineering) paired with de-escalation training (administrative) represent a complementary layered approach addressing both the physical environment and staff behavior.
