CHSP Hazard Identification, Risk Assessment & Control 5

Question 1

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?

Accepted Answer

Escalation factor

Answer

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.

Question 2

Which OSHA standard specifically requires healthcare employers to conduct annual exposure determinations and update their Exposure Control Plan?

Accepted Answer

29 CFR 1910.1030 (Bloodborne Pathogens)

Answer

29 CFR 1910.1030 mandates annual review and update of the Exposure Control Plan to reflect changes in tasks, procedures, and available safer devices.

Question 3

A root cause analysis team uses a fishbone (Ishikawa) diagram after a patient fall. The categories typically examined include all of the following EXCEPT:

Accepted Answer

Market share

Answer

Market share is a business metric, not one of the classic 6M fishbone categories (Man, Machine, Method, Material, Measurement, Mother Nature/Environment).

Question 4

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?

Accepted Answer

Health hazard

Answer

The blue (left) section of the NFPA 704 diamond indicates health hazard, rated 0–4 based on the degree of acute health risk.

Question 5

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?

Accepted Answer

Providing anti-fatigue matting at the surgical table

Answer

Anti-fatigue matting is a physical modification to the workstation (engineering control), while rotation schedules, breaks, and training are administrative controls.
