Domain 1: Safety Management 30% of exam
Question 1
A plant's annual records show five new work-related cases treated with sutures, three separate cases requiring injury-related restricted work after the injury day, and twelve first-aid-only cases meeting no other recording criterion. These groups do not overlap. Employees actually worked 400,000 hours and received another 40,000 hours of paid leave. What total recordable case incidence rate should management report, rounded to one decimal place?
Show answer & explanation
Correct answer: A - 4.0
Question 2
An experienced operator intends to stop a conveyor but presses an identical adjacent start button. Video and the operator's account agree that the correct procedure was understood and the wrong button was pressed unintentionally. In human-factors analysis, this action is classified as:
Show answer & explanation
Correct answer: C - A slip in executing the intended action.
Question 3
A manufacturer replaces its zero-reported-injury bonus with recognition for verified hazard corrections. Reporting definitions remain unchanged. Over eight weeks, near-miss reports triple, while injury rates and independent inspection findings show no clear trend. An executive calls the increase evidence that the new approach has made the plant less safe. Which interpretation is supported?
Show answer & explanation
Correct answer: C - Reporting may have improved; the underlying risk trend remains unproven.
Domain 2: Hazard Control Principles 39% of exam
Question 4
At a packing station, employees repeatedly lift 18-kg cartons from floor-level pallets onto a waist-high conveyor. Observations identify forceful lifting and deep bending as the principal exposures. Carton size and production volume cannot change. Which intervention best addresses both exposures at their source?
Show answer & explanation
Correct answer: C - Install a height-adjustable pallet positioner and a suitable mechanical lifting aid.
Question 5
A reactor has two high-pressure shutdown channels controlling separate valves; either valve can stop the feed. Both channels receive their pressure signal from one transmitter. During testing, the transmitter freezes at a low reading and neither channel trips as pressure rises. Which design change would preserve automatic shutdown if that transmitter failed again?
Show answer & explanation
Correct answer: B - Give one shutdown channel an independent pressure-sensing path.
Question 6
An industrial hygienist confirms that OSHA's additive-mixture rule applies to two airborne solvents affecting the same target organ. Representative eight-hour personal results are 30 ppm for solvent A, whose applicable eight-hour limit is 50 ppm, and 30 ppm for solvent B, whose limit is 100 ppm. What does the combined-exposure calculation establish for these measurements?
Show answer & explanation
Correct answer: A - The combined index is 0.90, below the additive-mixture limit.
Question 7
At a U.S. general-industry warehouse, a trained forklift operator must move a stable, secured load along a level aisle. The load is within rated capacity but blocks the forward view. The rearward route is clear, pedestrians are excluded, and reversing presents no additional hazard. How should the operator make the move?
Show answer & explanation
Correct answer: D - Travel with the load trailing, looking in the direction of travel.
Domain 3: Compliance Standards 31% of exam
Question 8
A plastics plant plans entry into a permit-required hopper. Testing shows 20.9% oxygen, no detectable flammable atmosphere, and acceptable concentrations of identified toxic contaminants. An overhead bin can still discharge enough pellets to engulf an entrant. The supervisor proposes ventilation-only alternate entry procedures under federal OSHA 1910.146. Which entry plan is defensible?
Show answer & explanation
Correct answer: D - Isolate the pellet feed and complete the required permit-entry safeguards.
Question 9
A coating department replaces a flammable product with a nonflammable formulation classified as a respiratory sensitizer. Employees have been trained on flammability and irritation, but not sensitization. The supervisor has uploaded the new safety data sheet and proposes waiting until the annual refresher to discuss it. Under federal OSHA Hazard Communication requirements, what is needed before employees begin using the product?
Show answer & explanation
Correct answer: B - Train affected employees on the newly introduced hazard and its protective measures.
Question 10
While engineering controls are being installed, an exposure assessment requires a workplace respiratory protection factor of 20 against a known vapor. The atmosphere is non-IDLH with 20.9% oxygen. A worker achieves a quantitative fit factor of 650 with a negative-pressure full-facepiece air-purifying respirator. Cartridge suitability, change schedule, medical clearance, training, and all other program requirements are satisfied. Under OSHA 1910.134, what do these results establish?
Show answer & explanation
Correct answer: B - The respirator passes fit testing and its assigned protection factor of 50 is adequate.
