When a fire alarm or smoke detector sounds in a healthcare building, what should a worker do first?

When a fire alarm or smoke detector sounds in a healthcare building, the immediate priority should be to ensure that the environment is as safe as possible for patients and staff. Closing all doors helps to contain the fire and smoke, preventing them from spreading rapidly. This creates a barrier that can protect those who may not be able to evacuate quickly, such as patients who are bed-bound or in critical care.

By closing doors, staff members can effectively limit the spread of the fire and buy valuable time for everyone to get to safety. In a healthcare setting, where the safety of vulnerable populations is paramount, this action is critical in maintaining control over the emergency situation until professional responders can arrive.

Reinforcing this action, other options would not be the immediate priority during an initial fire alarm. For instance, while evacuation is essential, it comes after ensuring that doors are closed. Turning off electrical equipment or calling the fire department should also occur after securing the area. Therefore, closing all doors is the most logical and protective first step.
