5 real sample questions

What is the overall purpose of 29 CFR 1910.212, the machine guarding standard?

A. To require replacement of all machines older than ten years

B. To protect operators and other employees from hazards such as those created by the point of operation, ingoing nip points, rotating parts, and flying chips and sparks

C. To require that all machines be operated only at night when fewer employees are present

D. To require every machine to be inspected by the fire department before use

Show answer and reasoning

Correct answer: B. To protect operators and other employees from hazards such as those created by the point of operation, ingoing nip points, rotating parts, and flying chips and sparks

A: The standard is hazard-based, not tied to a machine's age; it does not mandate replacing older equipment on a schedule.
C: The standard has no requirement dictating what shift or time of day machines may be operated.
D: Fire department pre-inspection of machinery is not a requirement of this standard.

Under the general requirements for machine guards, where should a guard be attached whenever possible?

A. To the machine itself

B. To the ceiling above the machine

C. To an adjacent, unrelated piece of equipment

D. To the employee's workstation chair

Show answer and reasoning

Correct answer: A. To the machine itself

B: Mounting a guard to the ceiling would not reliably keep it positioned relative to the hazard the way attachment to the machine does.
C: Attaching a guard to unrelated equipment would not consistently protect against the specific machine's hazard.
D: A guard mounted to a chair would not stay in position relative to the hazard as the operator moves.

Source: 29 CFR 1910.212(a)(2)

A machine guard, by design, must not:

A. Be made of metal

B. Itself create an additional hazard, such as a new pinch point or sharp edge

C. Be removable for maintenance

D. Cost more than the machine it protects

Show answer and reasoning

Correct answer: B. Itself create an additional hazard, such as a new pinch point or sharp edge

A: Guards are commonly made of metal or other durable materials; material choice alone is not the concern addressed by this requirement.
C: Guards may be designed to be removed for authorized maintenance; that is not what the "does not create a hazard" requirement addresses.
D: The standard does not set a cost ceiling relative to the machine's price.

Source: 29 CFR 1910.212(a)(2)

Which of the following is listed in the standard as an example of a machine guarding method?

A. Posting a warning sign near the machine with no physical barrier

B. Barrier guards, two-hand tripping devices, and electronic safety devices

C. Requiring employees to wear gloves at all times regardless of the hazard

D. Relying solely on verbal reminders from a supervisor

Show answer and reasoning

Correct answer: B. Barrier guards, two-hand tripping devices, and electronic safety devices

A: A sign alone, without a physical or engineering control, does not satisfy the guarding requirement.
C: Gloves are a form of personal protective equipment and are not, by themselves, one of the machine guarding methods described in this standard, and can be inappropriate or hazardous near certain moving parts.
D: Verbal reminders are administrative and do not constitute the physical or engineering guarding methods the standard describes.

Source: 29 CFR 1910.212(a)(1)

A two-hand tripping device is a guarding method that works by:

A. Requiring the operator to activate two separate controls simultaneously, keeping both hands out of the danger zone while the machine cycles

B. Allowing the operator to run the machine using only one hand while the other rests on the material

C. Automatically shutting off the machine at the end of each shift

D. Sounding an alarm without stopping or preventing machine motion

Show answer and reasoning

Correct answer: A. Requiring the operator to activate two separate controls simultaneously, keeping both hands out of the danger zone while the machine cycles

B: A two-hand device specifically requires both hands engaged on the controls; allowing one hand near the material would defeat its protective purpose.
C: A shift-end shutoff is a scheduling function, not how a two-hand tripping device protects the operator during operation.
D: An alarm alone, without preventing hand access to the danger zone, is not what a two-hand tripping device does.
