Rescue Operations - Phase 1: Pre-Entry

Because a successful rescue is based on proper planning, the first phase in an entry-required rescue is critical. All hazards and potential scenarios should be considered before entering the confined space in order to protect the rescuer and ensure a safe recovery of the victim.

The pre-entry steps listed below can be performed by a rescuer with awareness level training.

• Initiate the Incident Management System (IMS).
• Isolate the scene and deny entry to prevent further danger to victim(s), personnel, and bystanders. Initiate procedures for implementing site control and scene management.
• Size up the situation:
• Rescue vs. recovery
• Cause of incident
• Function being performed in the confined space
• Nature of injury or problem
• Number of victims
• Specific victim information
• Location of victim(s)
• Location of alternate entry and access points
• Permit-required or non-permit required space
• Initiate contact and establish communication with the victim(s).
• Obtain a copy of the confined space permit and, if possible, any blueprints or drawings of the confined space. Also obtain any Safety Data Sheets (SDS).
• Begin filling out the Fire Department Confined Space Entry Permit.
• Identify any possible or potential hazards and take appropriate steps to eliminate or minimize them. Ensure Lockout-tagout is done.
• Perform atmospheric monitoring for oxygen content, flammable gases and vapors, and toxic air contaminants. Continue to test periodically.
• Set up primary and secondary air supply systems that are ready to become operational.
