What is the correct action if flames are visible outside an exit?

• A. Block the exit
• B. Open the exit
• C. Proceed through that exit
• D. Call for help from outside

Answer: (A)

When flames are visible outside an exit, the immediate goal is to create a barrier between the fire and the space you’re in. Blocking the exit by closing the door, if you can do so safely, reduces the fire’s access to oxygen and slows its spread. This helps keep smoke and heat from rushing into your area and buys time to find a safer route or to wait for rescue. Opening the exit would feed the fire with more oxygen and let smoke surge in, making conditions more dangerous. Proceeding through the exit is not safe because the flames and heat could engulf you. Calling for help from outside is important if you’re trapped, but it doesn’t address the risk posed by an exit that’s compromised; securing the doorway is the best choice to protect the area while help arrives.
