What actions should be taken if exit routes are obstructed?

When exit routes are obstructed, notifying the building owner and ensuring that alternative routes are made available is the appropriate course of action. This is crucial because exit routes are essential for the safety of occupants during an emergency; they must remain clear at all times to allow safe evacuation. By informing the building owner, corrective actions can be taken promptly to mitigate risks and restore safe access or provide alternative means of egress.

Ensuring alternative routes are available is important because if primary exits are blocked, occupants need immediate options to escape safely. This aligns with fire safety regulations and practices that prioritize the protection of life in emergency situations.

The other actions, such as closing nearby doors or waiting for the fire department, do not address the immediate concern of obstructed exit routes. Blocking paths until an investigation could lead to increased danger for those needing to evacuate, as it enhances the risk of injury or panic. Therefore, taking proactive measures such as notifying the building owner and ensuring alternative routes are ready is the correct and safest response in such scenarios.
