An occupational health nurse reviewing OSHA 300 logs notices a cluster of hand lacerations in one production department over three months. This is an example of which hazard identification approach?
Answer: Reactive injury trend analysis
Analyzing OSHA 300 log injury patterns after they have occurred is a reactive approach that identifies hazard clusters through trend analysis of recorded incidents.
Which tool specifically uses a checklist methodology to systematically identify hazards associated with individual job tasks in a step-by-step manner?
Answer: Job Hazard Analysis (JHA)
A Job Hazard Analysis breaks each job into sequential steps and identifies potential hazards and controls for each step, providing a structured task-level hazard identification method.
A worker who handles pesticides daily is found to have cholinesterase levels 30% below their pre-employment baseline. This finding PRIMARILY indicates:
Answer: Organophosphate or carbamate pesticide absorption
Organophosphate and carbamate pesticides inhibit cholinesterase enzyme activity; a significant drop from baseline confirms systemic absorption and indicates a biological hazard exposure.
Under OSHA's Bloodborne Pathogen Standard (29 CFR 1910.1030), which workplace evaluation method is required to identify and document tasks that involve exposure to blood or OPIM?
Answer: Exposure determination
OSHA's Bloodborne Pathogen Standard requires employers to perform an exposure determination, identifying all job classifications and tasks with reasonably anticipated exposure to blood or OPIM.
Which factor would cause the occupational health nurse to classify a chemical as presenting a HIGHER inhalation hazard, even at a lower air concentration?
Answer: High vapor pressure and low permissible exposure limit
A chemical with high vapor pressure readily evaporates to create airborne concentrations, while a low PEL means even small concentrations are hazardous, together indicating a high inhalation hazard.
During a facility audit, an occupational health nurse identifies that flammable liquids are stored in standard metal cabinets rather than approved flammable storage cabinets. This represents which category of hazard?
Answer: Physical hazard – fire and explosion
Improper storage of flammable liquids creates a fire and explosion physical hazard; OSHA and NFPA standards require approved flammable liquid storage cabinets to contain vapors and withstand fire.
The occupational health nurse is assessing heat stress hazards in an outdoor construction site. Which environmental measurement is MOST useful for calculating the Wet Bulb Globe Temperature (WBGT) index?
Answer: Air temperature, humidity, radiant heat, and air movement
WBGT integrates natural wet bulb temperature (humidity/evaporation), globe temperature (radiant heat), and dry bulb temperature (air temperature) to provide a comprehensive heat stress index.
