Why should fire escape routes be kept free from hazards and doors along the route closed?

Keeping fire escape routes free from hazards and ensuring that doors along those routes are closed is essential for fire containment and safety. In the event of a fire, the primary goal is to prevent the fire from spreading to other areas, which can be accomplished by minimizing potential paths for the fire to travel. Open doors or blockages can create pathways that allow flames and smoke to move into previously safe areas, increasing the risk to those trying to evacuate.

Additionally, maintaining clear escape routes allows for a more orderly and speedy evacuation, ensuring that individuals can exit the building as quickly as possible during an emergency. While better air circulation and access are important considerations, the primary focus during a fire incident is to contain the fire and protect lives by allowing for effective evacuation without obstructions.
