What is a critical action to take when a fire alarm goes off?

When a fire alarm goes off, immediately beginning to evacuate is critical because the primary objective in such a situation is to ensure the safety of all individuals present. Fires can spread rapidly, and waiting for instructions or checking for the source of the fire can put lives at risk.

Evacuating promptly allows individuals to exit the building safely before conditions become dangerous. It is vital to know the designated evacuation routes and to follow established safety protocols. This action minimizes the potential for injury and ensures that emergency responders can access the scene without encountering individuals who may still be in hazardous areas. The focus should always be on facilitating a safe exit rather than trying to identify the source of the alarm or waiting for additional guidance.
