How should you respond if your SCBA fails to deliver air during an escape route?

• A. Stop and call for assistance; exit to a safe route using available backups and notify command.
• B. Continue to move toward the location of the incident.
• C. Remove the regulator and breathe ambient air.
• D. Wait for instructions without moving.

Answer: (D)

When the SCBA stops delivering air, the priority is to stop and manage the emergency immediately. You don’t want to push further into a space without breathable air. Instead, call for assistance, use any backup air sources or a buddy if available, and move to a known safe exit while notifying command so rescue can be coordinated. This preserves the remaining air you have, reduces exposure to the hazard by getting you out of the danger zone, and gets help on the scene quickly. Continuing toward the incident is dangerous because there’s no guaranteed supply of breathable air. Removing the regulator to breathe ambient air is not safe in an IDLH environment, since the air in that space may be contaminated. Waiting for instructions without moving wastes precious time and can leave you trapped.
