COHN Workplace Hazard Identification 5

Question 1

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?

Accepted Answer

Reactive injury trend analysis

Answer

Analyzing OSHA 300 log injury patterns after they have occurred is a reactive approach that identifies hazard clusters through trend analysis of recorded incidents.

Question 2

Which tool specifically uses a checklist methodology to systematically identify hazards associated with individual job tasks in a step-by-step manner?

Accepted Answer

Job Hazard Analysis (JHA)

Answer

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.

Question 3

A worker who handles pesticides daily is found to have cholinesterase levels 30% below their pre-employment baseline. This finding PRIMARILY indicates:

Accepted Answer

Organophosphate or carbamate pesticide absorption

Answer

Organophosphate and carbamate pesticides inhibit cholinesterase enzyme activity; a significant drop from baseline confirms systemic absorption and indicates a biological hazard exposure.

Question 4

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?

Accepted Answer

Exposure determination

Answer

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.

Question 5

Which factor would cause the occupational health nurse to classify a chemical as presenting a HIGHER inhalation hazard, even at a lower air concentration?

Accepted Answer

High vapor pressure and low permissible exposure limit

Answer

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.
