What this exam covers

Permit Space Entry Roles, Testing, Rescue and Training (1910.146)100%

5 real sample questions

How often must employer-designated rescue personnel practice making permit space rescues?

A. At least once every 12 months

B. At least once every 5 years

C. Only once, during initial training

D. Only after an actual rescue has occurred

Show answer and reasoning

Correct answer: A. At least once every 12 months

B: Far too infrequent for a skill that has to be reliable under pressure.
C: A single training session does not maintain proficiency over years of service.
D: Waiting for a real rescue to be the first practice defeats the purpose of practicing at all.

Source: 1910.146(k)(2)(iv)

What must an entry supervisor do if conditions arise that are not allowed under the entry permit?

A. Terminate entry and cancel the permit

B. Note the deviation in a logbook and allow entry to continue

C. Wait until the end of the shift to address it

D. Delegate the decision to the authorized entrant inside the space

Show answer and reasoning

Correct answer: A. Terminate entry and cancel the permit

B: Logging a problem without stopping entry does not remove the entrant from a hazard that is actively developing.
C: A prohibited condition needs to be addressed immediately, not at shift end.
D: The entrant inside the space is not positioned to make the entry-authorization call; that responsibility stays with the entry supervisor.

Source: 1910.146(j)(3)-(4)

Who is the "entry supervisor" under the permit space standard?

A. The person responsible for determining if acceptable entry conditions exist, authorizing entry, overseeing entry operations, and terminating entry as required

B. Any employee who happens to be closest to the space when work begins

C. The company safety officer, regardless of whether they are present at the site

D. The employee who physically enters the space to perform the work

Show answer and reasoning

Correct answer: A. The person responsible for determining if acceptable entry conditions exist, authorizing entry, overseeing entry operations, and terminating entry as required

B: Proximity does not create the role; someone has to be assigned and accountable for the specific duties in 1910.146(j).
C: The entry supervisor must actually be able to evaluate conditions and act; a title alone does not satisfy the definition if that person is not overseeing the entry.
D: That describes the authorized entrant, a separate role with separate duties.

Source: 1910.146(b): Entry supervisor, definition

Before authorizing entry into a permit space, what must the entry supervisor verify?

A. That all tests specified by the permit have been conducted and that the procedures and equipment specified by the permit are in place

B. That the entrant has at least five years of experience

C. That the space has been entered successfully before without incident

D. That the attendant has signed a liability waiver

Show answer and reasoning

Correct answer: A. That all tests specified by the permit have been conducted and that the procedures and equipment specified by the permit are in place

B: The standard does not set a tenure requirement; it requires training and demonstrated competency.
C: A clean history is not a substitute for verifying current conditions.
D: Not a requirement of the standard.

Source: 1910.146(j)(1)

Where must an attendant be positioned during entry operations?

A. Outside the permit space, for the entire duration of entry operations

B. Inside the permit space alongside the entrant

C. Anywhere on the jobsite, as long as they carry a radio

D. At the site office, monitoring by camera only

Show answer and reasoning

Correct answer: A. Outside the permit space, for the entire duration of entry operations

B: An attendant who enters the space is no longer available to summon help or monitor from safety, and is now exposed to the same hazard.
C: General jobsite presence does not meet the requirement to be positioned to monitor the specific entry.
D: Remote monitoring by camera is not what the standard requires; the attendant has to be positioned to actually monitor and respond.
