Episode 126 breaks down the core duties of the confined space entry team—entrants, attendants, and supervisors—and how each role contributes to keeping confined space work controlled, compliant, and safe. Dr. Ayers emphasizes that confined space entry is a team activity, and failure in any role increases risk for everyone.
Confined space entry succeeds only when every role understands and performs its duties. Entrants, attendants, and supervisors each serve as a critical layer of protection.
Entrants are the individuals physically entering the space. Their responsibilities include:
Understanding the hazards of the space.
Knowing the signs and symptoms of exposure.
Wearing required PPE and using assigned equipment.
Maintaining communication with the attendant.
Exiting immediately if:
An alarm sounds
Conditions change
They feel symptoms
The attendant orders evacuation
Entrants must never enter without authorization or deviate from the permit conditions.
The attendant is the lifeline for the entrant. Their responsibilities include:
Remaining outside the space at all times.
Maintaining constant communication with entrants.
Monitoring for hazards inside and outside the space.
Preventing unauthorized entry.
Ordering evacuation when conditions become unsafe.
Initiating rescue procedures (but never entering the space themselves).
Knowing how to use rescue equipment and how to contact rescue services.
The attendant must stay focused—no distractions, no multitasking.
The supervisor ensures the entire entry process is safe and compliant:
Verifies the space classification and hazard assessment.
Confirms atmospheric testing is complete and acceptable.
Ensures isolation, ventilation, and controls are in place.
Checks that all team members are trained and competent.
Reviews and signs the entry permit.
Stops the entry if conditions change.
Closes out the permit after the job is complete.
The supervisor is the final checkpoint before anyone enters.
Confined spaces are dynamic—conditions can shift quickly.
Clear role separation prevents confusion during emergencies.
Each role provides a layer of defense against atmospheric hazards, engulfment, entrapment, and other confined space risks.
When roles are blurred or ignored, incidents escalate rapidly.
Confined space entry is a coordinated effort. Entrants, attendants, and supervisors each carry essential responsibilities that protect the entire team. When everyone understands their role and performs it consistently, confined space work becomes predictable, controlled, and far safer.
