Why should fires that start in means of egress be treated with caution?

Fires that start in means of egress should be treated with caution primarily because they often lead to smoke-filled conditions. Means of egress, such as stairwells, hallways, or exits, are crucial pathways for occupants to evacuate safely during an emergency. When a fire occurs in these areas, the smoke can quickly accumulate, creating hazardous conditions for both occupants and responding firefighting personnel. The presence of smoke not only reduces visibility but also poses serious respiratory hazards, complicating evacuation and rescue efforts.

In situations where smoke fills a means of egress, occupants may become disoriented and unable to find their way out, increasing the potential for injury or fatalities. It is essential for firefighters to assess the situation accurately and take appropriate action to manage the fire while ensuring safe access for evacuation. Recognizing the dangers posed by smoke in these critical exit pathways underlines the need for caution when dealing with fires in such locations.
