What should personnel do if they encounter smoke while escaping?

Staying low to the ground and covering the mouth and nose is the recommended action to take if personnel encounter smoke while escaping. Smoke rises due to its heat, creating a cleaner and safer atmosphere closer to the ground. By remaining low, individuals are less likely to breathe in toxic smoke and fumes that can cause disorientation or unconsciousness. Covering their mouths and noses with a cloth or other material can also help filter out some of the harmful particles in the smoke, providing a better chance of maintaining clear airways until they can escape to safety.

Running quickly to the exit may not be advisable in the presence of smoke, as the urgency can lead to panic and poor decision-making. Waving arms to signal for help is less effective when immediate action for survival is required, and relying on others might not be wise given the urgency of the escape. Covering heads and yelling is also not effective for personal safety; it does not address the critical need to avoid inhaling smoke or protect the respiratory system during an escape.
