Sections covered on the exam: Domain 2 · Program Management, Domain 4 · Emergency Management, Domain 3 · Risk Management.
Question 1 · Domain 2 · Program Management
Answer: D. Relocate the air-handling equipment to a ground-level mechanical room
Relocating the equipment to grade avoids the fall hazard entirely, the top level of the Prevention through Design hierarchy. Roof anchors still rely on workers using personal fall arrest correctly, a warning line is a lower-order administrative barrier that leaves the edge exposed, and a written plan with training is purely administrative. PtD favors decisions that keep the hazard out of the workplace over controls that manage exposure to it.
Question 2 · Domain 2 · Program Management
Answer: B. 4,800 lb
A uniform 60 in crate has its load center at 60 ÷ 2 = 30 in. Allowable ≈ 6,000 × (24 ÷ 30) = 4,800 lb. Inverting the ratio (30 ÷ 24) gives 7,500 lb, which would overload the truck. Using the full 60 in length as the load center gives 2,400 lb. Assuming the rated 6,000 lb applies ignores the longer load center. The manufacturer's capacity plate or load chart governs in practice.
Question 3 · Domain 4 · Emergency Management
Answer: B. Consultation and participation of non-managerial workers
ISO 45001 has an explicit leadership requirement for consultation and participation of workers, specifically including non-managerial workers in determining hazards, controls and the hierarchy of controls applied. The other options are genuine requirements, but scope definition, outsourcing control and management review are not what this practice violates.
Question 4 · Domain 3 · Risk Management
Answer: D. $52,500
Manual premium = (2,500,000 ÷ 100) × 8.40 = 25,000 × 8.40 = $210,000. Modified premium = 210,000 × 1.25 = $262,500. The added cost (debit) = 262,500 − 210,000 = $52,500. $262,500 is the total modified premium, not the increase. $210,000 is the manual premium. $21,000 results from misplacing the per-$100 conversion by a factor of ten.
Question 5 · Domain 2 · Program Management
| Period | Duration | Concentration |
|---|---|---|
| 1 | 2 h | 120 ppm |
| 2 | 3 h | 60 ppm |
| 3 | 2 h | 40 ppm |
| 4 | 1 h | 0 ppm (no exposure, documented) |
Answer: C. 62.5 ppm
TWA = Σ(C × t) ÷ 8 h = (120 × 2 + 60 × 3 + 40 × 2 + 0 × 1) ÷ 8 = 500 ÷ 8 = 62.5 ppm. The unsampled final hour is a documented zero exposure and still counts in the 8-hour denominator. Dividing by the 7 sampled hours gives 71.4 ppm; averaging the three concentrations without time weighting gives 73.3 ppm.
Question 6 · Domain 2 · Program Management
Answer: B. Specify a water-based coating that meets the same performance requirements
Substituting a water-based coating removes most of the flammable vapor and much of the inhalation hazard at the source, ranking above engineering controls in the PtD hierarchy. Explosion-proof equipment and LEL interlocks are engineering controls that manage a flammable atmosphere that still exists. Supplied-air respirators are PPE, the least effective tier. Substitution should be verified to avoid introducing a new hazard such as an isocyanate hardener.
Question 7 · Domain 2 · Program Management
Answer: A. Harness and short lanyard attached to the platform's designated anchor
In boom-supported lifts, workers must be tied off to the boom or basket at the manufacturer's designated anchorage, ideally in a restraint configuration that prevents ejection from the platform. Tying off to an adjacent structure can pull the worker out if the lift moves. Body belts are not permitted for fall arrest and the guardrail is not an approved anchorage. Guardrails alone are inadequate for boom lifts because of catapult and ejection hazards.
Question 8 · Domain 4 · Emergency Management
Answer: C. Rate aspects against defined criteria such as severity and legal duties
ISO 14001 requires the organization to identify aspects and their impacts from a life-cycle perspective and to determine significance using established criteria, which typically include severity, probability, compliance obligations and the concerns of interested parties. Limiting to permitted aspects misses unregulated impacts, choosing by cost defeats the purpose, and labeling everything significant prevents prioritization.
Question 9 · Domain 3 · Risk Management
Answer: C. Sprinklers are loss reduction; the smoking ban and hot work permits are loss prevention
Loss prevention reduces the frequency of loss by keeping the event from occurring, as smoking bans and hot work permits control ignition sources. Loss reduction reduces the severity of losses that do occur; sprinklers do not prevent ignition but limit fire spread and damage. Reversing the labels confuses frequency with severity. Premium credits are a benefit of risk control, not a transfer of risk to another party.
Question 10 · Domain 2 · Program Management
Answer: C. About 94.5 dBA
Decibels add logarithmically: L = 10 log(10^8.8 + 10^8.8 + 10^9.2) = 10 log(6.31 × 10⁸ + 6.31 × 10⁸ + 15.85 × 10⁸) = 10 log(2.85 × 10⁹) = 94.5 dBA. Two equal 88 dBA sources combine to 91 dBA; adding 92 dBA yields about 94.5 dBA. Arithmetic averaging gives 89.3 dBA, taking the loudest source alone gives 92 dBA, and arithmetic addition gives 268 dBA.
