Establishing a safe perimeter around the area is the first crucial action a firefighter should take upon arriving at a munitions fire scene. This step is essential for ensuring the safety of both responders and bystanders. Munitions fires can involve the risk of explosive materials, which can lead to significant hazards such as shrapnel, fireballs, or secondary explosions. By establishing a safe perimeter, firefighters can effectively manage the incident, preventing unauthorized individuals from entering the potentially dangerous area and allowing responders to focus on controlling the situation.

Additionally, establishing a perimeter allows the incident commander to assess the scene and develop an incident action plan while keeping all personnel out of harm's way. This action sets the foundation for all subsequent operations, ensuring a structured approach to mitigating the fire and protecting lives.

Other options, while important components of incident response, do not take precedence in this context. Immediate extinguishing of the fire without assessment can be highly dangerous given the unpredictable nature of explosive materials. Calling for backup, while sometimes necessary, is usually part of the initial assessment rather than the most immediate action. Lastly, assessing wind direction is a critical factor in firefighting tactics, particularly in understanding how the fire may spread, but it should occur after establishing a secure zone.
