The OSHA Process Safety Management (PSM) standard (29 CFR 1910.119) applies to facilities that use highly hazardous chemicals above threshold quantities. Which element does the PSM standard specifically require to identify workplace hazards?
Answer: Process hazard analysis
OSHA PSM requires process hazard analysis (PHA) as one of its 14 elements to systematically identify, evaluate, and control hazards associated with highly hazardous chemical processes.
Which early indicator would MOST alert the occupational health nurse to a potential musculoskeletal hazard in a warehouse operation?
Answer: Workers self-reporting discomfort during end-of-shift symptom surveys
End-of-shift symptom surveys capture early musculoskeletal discomfort before injuries occur, providing the earliest and most actionable signal of ergonomic hazards.
An industrial hygienist's sampling shows that workers' 8-hour TWA benzene exposure is 0.4 ppm. OSHA's action level for benzene is 0.5 ppm. What should the occupational health nurse recommend?
Answer: Monitor exposure levels and conduct medical surveillance
Although currently below the action level, the close proximity warrants continued exposure monitoring and consideration of medical surveillance, as levels can fluctuate above 0.5 ppm.
Which component of a Safety Data Sheet (SDS) is MOST useful for identifying acute health hazards associated with a chemical?
Answer: Section 2 – Hazard(s) identification
SDS Section 2 provides the GHS hazard classification, signal words, hazard statements, and pictograms that directly describe acute and chronic health hazards.
A construction site occupational health nurse observes workers cutting concrete without wet methods or respiratory protection. Which hazard does this PRIMARILY represent?
Answer: Crystalline silica inhalation hazard
Dry cutting of concrete generates respirable crystalline silica dust, which can cause silicosis, lung cancer, and COPD, representing the primary hazard in this scenario.
When an occupational health nurse conducts a worksite walk-through, which observation is MOST indicative of an uncontrolled chemical hazard?
Answer: Unlabeled containers stored near an emergency eyewash station
Unlabeled containers violate OSHA's Hazard Communication Standard and prevent workers from identifying chemical hazards, constituting a direct uncontrolled hazard.
Which radiation hazard is MOST commonly encountered by healthcare occupational health nurses in hospital settings?
Answer: Ionizing radiation from diagnostic imaging equipment
Ionizing radiation from X-ray, fluoroscopy, and nuclear medicine equipment is the most prevalent radiation hazard in healthcare settings requiring occupational health monitoring.
