What is one of the first actions a supervisor should take upon arrival at a major fire?

The appropriate action for a supervisor upon arrival at a major fire involves ensuring that appropriate notifications have been made to the fire department. This step is crucial as it establishes the basis for an organized response to the incident. Timely notification enables the mobilization of necessary resources to combat the fire effectively and ensures that the fire department can allocate the right personnel and equipment.

Establishing optimal communication channels is vital in emergency situations, as it facilitates coordination between various responding agencies and ensures that all necessary parties are informed about the unfolding situation. This action supports the overall incident command structure, which is essential for managing emergencies effectively.

While ensuring crowd control procedures, conducting site assessments for hazards, and providing first aid are important actions, they typically follow the initial notification to the appropriate emergency services. The priority usually lies in ensuring that specialized resources, such as fire fighters, are deployed to address the immediate threat posed by a major fire.
