7.3 PRCS Entry Roles: Entrant, Attendant, Entry Supervisor & Permit System

7.3 PRCS Entry Roles: Entrant, Attendant, Entry Supervisor & Permit System

Overview of Defined Entry Roles (29 CFR 1910.146(h), (i), (j))

OSHA's Permit-Required Confined Space standard establishes clear division of responsibilities to ensure safe entry operations. The standard defines three distinct roles: Authorized Entrant, Attendant, and Entry Supervisor. Each individual participating in a permit space entry must be trained and proficient in their assigned duties.

---

1. Authorized Entrant (29 CFR 1910.146(h))

An Authorized Entrant is an employee who is authorized by the employer to enter a permit space. Entrants are exposed directly to the internal space environment.

Core Responsibilities of Authorized Entrants

• Know Space Hazards: Understand the hazards that may be faced during entry, including information on the mode, signs or symptoms, and consequences of exposure.
• Properly Use Equipment: Correctly operate testing, monitoring, ventilating, lighting, communication, personal protective (PPE), ladders, and retrieval equipment.
• Maintain Communication: Communicate with the attendant as necessary to enable the attendant to monitor entrant status and enable the attendant to alert entrants of the need to evacuate.
• Alert the Attendant: Immediately notify the attendant whenever the entrant recognizes any warning sign or symptom of exposure to a dangerous situation, or detects a prohibited condition.
• Evacuate Immediately: Exit the permit space as quickly as possible whenever:
  1. An order to evacuate is given by the attendant or entry supervisor.
  2. The entrant recognizes any warning sign or symptom of exposure.
  3. An automatic evacuation alarm triggers (e.g., continuous multi-gas monitor alarm).

2. Authorized Attendant (29 CFR 1910.146(i))

An Attendant is an individual stationed outside one or more permit spaces who monitors the authorized entrants and performs all attendant's duties assigned in the employer's permit space program.

+---------------------------------------------------------------------------------+
|                       THE ATTENDANT's ABSOLUTE MANDATE                          |
+---------------------------------------------------------------------------------+
|  1. REMAIN STATIONED OUTSIDE THE PERMIT SPACE AT ALL TIMES DURING ENTRY.        |
|  2. NEVER ENTER THE SPACE TO PERFORM RESCUE UNDER ANY CIRCUMSTANCES             |
|     (Unless properly relieved by another trained attendant AND executing       |
|      non-entry retrieval or authorized dual-role rescue protocol).              |
|  3. MAINTAIN CONTINUOUS COUNT AND IDENTIFICATION OF ALL ENTRANTS.              |
|  4. ORDER IMMEDIATE EVACUATION UPON DETECTING PROHIBITED CONDITIONS.            |
+---------------------------------------------------------------------------------+

Core Responsibilities of Attendants

• Continuous Stationing: Remains outside the permit space portal during entry operations until relieved by another qualified attendant.
• Entrant Count & Identification: Maintains an accurate count of authorized entrants in the permit space and ensures that the permit accurately identifies who is inside.
• Communication & Monitoring: Communicates with entrants as necessary to monitor status; monitors activities inside and outside the space to determine if it remains safe.
• Order Evacuation: Orders entrants to evacuate the permit space immediately under any of the following conditions:
  • Detection of a prohibited condition.
  • Detection of behavioral changes or symptoms of hazard exposure in an entrant.
  • Detection of a situation outside the space that could endanger entrants (e.g., generator exhaust fumes blowing into ventilation intake).
  • If the attendant cannot effectively perform all assigned duties.
• Summon Rescue: Summons rescue and other emergency services as soon as the attendant determines that entrants need assistance to escape.
• Perform Non-Entry Rescue: Operates mechanical retrieval winches to pull entrants out during emergencies.
• No Distracting Duties: Performs no duties that might interfere with the attendant's primary duty to monitor and protect entrants.

3. Entry Supervisor (29 CFR 1910.146(j))

The Entry Supervisor is the person (such as a foreman, crew chief, or safety manager) responsible for determining if acceptable entry conditions are present, authorizing entry, overseeing entry operations, and terminating entry as required.

Core Responsibilities of Entry Supervisors

• Verify Permit & Tests: Knows space hazards; verifies that appropriate entries have been made on the permit, that all tests specified by the permit have been conducted, and that all procedures/equipment are in place before signing.
• Authorize Entry: Signs the entry permit to authorize entry to begin.
• Verify Rescue Services: Determines that rescue services are available and that the means for summoning them are operational.
• Maintain Acceptable Entry Conditions: Removes unauthorized individuals who attempt to enter or who enter the permit space.
• Terminate Entry & Cancel Permit: Cancels the permit when entry operations are completed or when a prohibited condition arises.

The Entry Permit System (29 CFR 1910.146(f))

The Entry Permit is a written or printed document provided by the employer to allow and control entry into a permit space. Under 1910.146(f), the permit must document 14 mandatory content items:

1. Permit space to be entered and location.
2. Purpose of the entry.
3. Date and authorized duration of the permit.
4. Names of authorized entrants.
5. Names of current attendants.
6. Name and signature of the entry supervisor.
7. Hazards of the permit space to be entered.
8. Measures used to isolate the space and eliminate/control hazards (LOTO, ventilation, blinding).
9. Acceptable entry conditions.
10. Results of initial and periodic atmospheric tests (accompanied by names of testers and test times).
11. Rescue and emergency services that can be summoned and contact methods.
12. Communication procedures used by entrants and attendants.
13. Equipment required (PPE, testing, alarm, rescue, lighting).
14. Any other necessary information or additional permits (e.g., Hot Work Permit).

Posting and Cancellation Requirements

• Posting: The completed permit must be posted at the entry portal or made equally available to all entrants before entry begins.
• Cancellation: The entry supervisor must cancel the permit when entry operations are completed OR when a prohibited condition arises in or near the space.
• 1-Year Record Retention Rule (1910.146(e)(6)): The employer must retain each canceled entry permit for at least 1 year after cancellation. 1910.146(d)(14) then requires the employer to review the permit-space program using those retained permits within 1 year after each entry, revising the program as necessary. Keep the split straight: (e)(6) = retention; (d)(14) = annual program review.
