What should occupants do if the exit stair becomes impassable due to smoke?

The most effective response for occupants when faced with an impassable exit stair due to smoke is to return to their office to defend in place. This approach prioritizes safety by allowing occupants to remain in a location that they can secure against smoke and fire, using available resources such as damp cloths to seal gaps and closing doors to prevent smoke from entering.

In situations where the exit route is compromised, returning to a known safe area can often provide more protection than risking exposure to smoke and fire in an alternative route or moving upwards. This strategy is also in line with emergency response protocols, which emphasize that individuals should find a safe refuge and wait for assistance from emergency responders who are trained to navigate hazardous environments.

Choosing this option supports tenants in minimizing their risk and ensuring that well-meaning decisions do not inadvertently lead them into greater danger.
