Correct answer: D. Piping

The word "schedule" is how pipe is classified. A schedule number describes the thickness of the pipe wall: as the schedule goes up, so does the wall thickness, while the outside diameter of a standard pipe is held constant. That is why thicker-walled options such as Schedule 80 or Schedule 120 (available in PVC or steel) are chosen for higher fluid pressures. Schedule 40 is simply one of the more common wall thicknesses. Note that electrical conductors are rated by "gauge," not by schedule.

Correct answer: B. Overloaded circuit

Every conductor and component in a circuit is rated to carry only so much current safely. Pull more than that — by stacking too many devices onto one circuit or by running a single tool that draws excessive current — and the wiring heats up. Enough heat can start a fire, and if insulation melts, arcing may follow, sometimes hidden inside a wall. That is the hazard of an overloaded circuit. By contrast, a GFCI watches for an imbalance between the hot and neutral conductors; a leakage (ground fault) current trips it off, guarding the worker against shock. Exposed electrical parts describe live wiring or components left accessible, such as when a panel cover is missing. Improper grounding means a system that is not correctly grounded, allowing metal on motors or appliances to become energized because stray voltage has no safe path away.

Correct answer: B. EMR > 1.0

An EMR expresses how a company's workers' compensation history stacks up against peer companies in the same industry and state, and insurers plug it into the premium calculation. Because a claim record worse than the peer average signals greater-than-average risk, that company lands above 1.0 and pays a higher premium. An EMR of exactly 1.0 marks a company sitting right at the industry average, while a figure under 1.0 reflects a better-than-average record and a lower, less-risky premium. The rate itself draws on claims from the three years prior to the most recent one — a 2018 EMR, for instance, uses 2014 through 2016 rather than 2017.

Correct answer: B. The material is caustic

Any reading above 7 on the pH scale places a material in the basic, or caustic, range. Many caustics are indeed toxic, yet when they are unbuffered the body copes with them fairly readily because they dilute so easily.

Correct answer: C. 13.33 mrem/h

The inverse square law says I₂ = I₁ × (d₁² / d₂²). Plugging in the numbers gives I₂ = 120 × (2² / 6²) = 120 × (4 / 36) ≈ 13.33 mrem/h, which is the correct answer. The 20.00 mrem/h choice comes from scaling by the plain distance ratio instead of its square. The 40.00 mrem/h figure represents a miscalculation that undercounts how much distance cuts the dose. The 60.00 mrem/h option results from simply halving the reading rather than squaring the distance ratio.

Correct answer: B. 20 feet or more

Once a trench reaches 20 feet or deeper, its protective system can no longer rely on a standard tabulated design — a registered professional engineer must design it, as spelled out in 29 CFR 1926.652(b) and (c).

Correct answer: B. Developing task procedures

Task analysis breaks a job into discrete steps so that hazards, required actions, and controls can be pinned down. You do that by observing the work as it actually happens, by taking measurements that quantify exposures or ergonomic loads, and by reading the applicable policies to see how the written rules compare with practice. Writing the task procedures is not one of these methods — it is a product that comes after the analysis, because the hazards and control gaps the analysis surfaces are what shape the procedures you then create or revise. Observing reveals real workflow, human factors, and departures from documented guidance. Measuring supplies objective data on the environmental or ergonomic conditions driving risk. Reviewing the relevant policies exposes gaps between what the documents require and what workers actually do.

Correct answer: B. 785 ft/min

Surface velocity — the linear speed at the wheel's rim — equals the circumference times the rotational speed. Using C = πd with a 6-inch diameter gives 3.14 × 6 = 18.84 inches; dividing by 12 converts that to 1.57 feet per revolution. Multiply 1.57 feet by 500 rpm and you get 785 ft/min, the figure a safety professional would compare against the manufacturer's rated limits. The 78.5 ft/sec answer stems from a botched unit conversion (785 ft/min is really about 13.1 ft/sec, not 78.5). The 39.2 ft/sec choice overstates the speed by dividing incorrectly rather than by 60 to reach seconds. The 392.5 ft/min value is exactly half of the right answer, which happens if the diameter or the rpm gets mistakenly cut in two during the math.

Correct answer: D. Workers removing the wheel guard

Product literature covers the hazards tied to using a tool the way it was meant to be used. What it often cannot anticipate are the behavioral hazards workers create by modifying the equipment — and stripping off the wheel guard is a prime example. That guard exists to shield the operator from flying fragments if the wheel bursts and to steer sparks and debris away. Take it off for better sightlines or access and you have defeated a key engineering control, sharply raising the odds of deep cuts, amputation, or a fatal wheel failure. A safety professional has to keep in mind that rule-breaking and human factors generate risks the manufacturer never spelled out. Mounting a wheel that does not fit the grinder is, by contrast, something manuals address head-on: they list compatible wheel types, sizes, and speed ratings precisely because a mismatch can wreck the wheel. Running an ungrounded extension cord is likewise a well-documented electrical hazard, since makers routinely warn about damaged cords and missing grounds that invite shock or fire. Kickback, too, is a recognized operating hazard — literature commonly describes the sudden reactive force when a wheel binds and offers grip and positioning guidance to counter it.

Correct answer: C. 4

Standing still, the 220-pound worker already feels 1 G, since weight is gravity acting on mass. To find the extra G's produced by arresting the fall, subtract the worker's weight from the arresting force: 1,100 − 220 = 880 pounds of additional force. Because 1 G corresponds to 220 pounds here, 880 ÷ 220 = 4 additional G's.
