Which step is part of the fire response sequence in a facility?

The step that is part of the fire response sequence in a facility is to activate the alarm and report the fire. This action is crucial as it ensures that the appropriate emergency services are notified immediately, enabling a prompt response to the situation. Early detection and alarm activation can save lives by allowing occupants to evacuate quickly while also alerting firefighters to the location and nature of the fire.

In a facility, activating the alarm can trigger automatic systems designed to enhance safety, such as fire suppression systems, which can help control the fire even before firefighters arrive. Furthermore, it mobilizes staff members and emergency response teams, ensuring that everyone is aware of the emergency and can take necessary evacuation measures.

The other options, while potentially relevant in a comprehensive fire safety plan, do not constitute primary steps in the immediate fire response sequence. Notifying family members, for instance, may occur later when safety has been secured, and closing the main entrance may not be feasible or practical under urgent circumstances. Using a blanket to apply pressure to the fire may be a technique for small fires but is not a standard response step that applies universally in facility settings.
