5 real sample questions

What must lockout and tagout devices be capable of, per the standard?

A. Withstanding the environment to which they are exposed for the maximum period of time that exposure is expected

B. Being removed by hand without a key or combination

C. Changing color when energy is present

D. Transmitting a wireless signal to a central office

Show answer and reasoning

Correct answer: A. Withstanding the environment to which they are exposed for the maximum period of time that exposure is expected

C: Not a requirement of the standard.
D: No such requirement exists in the standard.

Source: 1910.147(c)(5)(ii)(A)

Lockout and tagout devices must be standardized within a facility in at least which of the following?

A. Color, shape, or size

B. Manufacturer only

C. Price point

D. Country of origin

Show answer and reasoning

Correct answer: A. Color, shape, or size

B: Manufacturer alone does not create the visual recognizability the standard is after.
C: Cost has nothing to do with recognizability.
D: Origin is not a factor in the standard's device requirements.

Source: 1910.147(c)(5)(ii)(B)

Who is an "authorized employee" under the lockout/tagout standard?

A. A person who locks out or tags out machines or equipment in order to perform servicing or maintenance

B. Any employee who works in the same building as the equipment

C. A supervisor with hiring and firing authority

D. An employee whose only job is watching a machine run

Show answer and reasoning

Correct answer: A. A person who locks out or tags out machines or equipment in order to perform servicing or maintenance

B: Physical proximity does not create the role; the person has to actually lock out or tag out the equipment.
C: Management authority is not what the definition turns on.
D: Someone who only observes equipment operate, with no servicing role, does not meet this definition. That describes an "affected employee" at most.

Source: 1910.147(b): Authorized employee, definition

Before a machine is turned off to begin servicing, what must the authorized employee know?

A. The type and magnitude of the energy, the hazards of that energy, and the method or means to control it

B. Only the manufacturer's warranty period

C. The machine's original purchase price

D. The names of every previous operator of the machine

Show answer and reasoning

Correct answer: A. The type and magnitude of the energy, the hazards of that energy, and the method or means to control it

B: Warranty terms have no bearing on energy control.
C: Cost information is irrelevant to the hazard being controlled.
D: Operator history does not tell you what energy sources exist or how to isolate them.

Source: 1910.147(d)(1)

How must a machine be turned off before lockout is applied?

A. Using the established shutdown procedure, in an orderly manner that avoids additional or increased hazards

B. By pulling the main breaker without warning, however the machine happens to be operating

C. By waiting for the machine to run out of material and stop on its own

D. By disconnecting only the control panel display

Show answer and reasoning

Correct answer: A. Using the established shutdown procedure, in an orderly manner that avoids additional or increased hazards

B: Cutting power without following the established sequence can create the exact hazard the procedure is designed to avoid.
C: Waiting for a machine to idle out is not a controlled shutdown and does not address stored energy.
D: A display is not an energy isolating device and disconnecting it does not shut down the machine.
