Big Rig Fire Response: Operational Overview and Lessons

Responding to a big rig fire presents unique challenges due to the size of the vehicle, potential hazardous cargo, and complex fire behavior. In this incident, the crew arrives on scene to find a large commercial truck fully involved in fire. Initial actions focus on establishing a safe perimeter, identifying hazards, and deploying appropriate suppression tactics.

Initial Size-Up and Safety Protocols

Upon arrival, the crew conducts a thorough size-up, assessing fire location, intensity, and potential fuel sources. The use of full PPE and SCBA is mandatory given the toxic smoke and risk of sudden fire spread. Command establishes a hot zone and ensures all personnel maintain situational awareness. Apparatus are positioned upwind and uphill where possible to reduce exposure to heat and smoke. Identifying any hazardous materials placards is critical for determining additional risks and required resources.

Fire Suppression and Operational Coordination

The attack crew initiates a coordinated water application, focusing on cooling the fuel tanks and controlling fire spread to surrounding areas. Use of a combination of straight streams and fog patterns helps penetrate the fire while protecting firefighters from radiant heat. Ventilation is limited due to the vehicle's construction but is managed carefully to avoid feeding the fire. Communication between interior and exterior crews ensures efficient water flow and safety monitoring. This incident underscores the importance of rapid risk assessment, proper PPE use, and coordinated tactics when confronting large vehicle fires.

Firefighters operating at big rig fires must remain vigilant for potential explosions, hazardous cargo, and structural collapse of the vehicle. Continuous evaluation and adherence to safety protocols are essential for successful fire suppression and crew safety.
