Study Notes

ARFF Guidelines Overview

Each aircraft fire requires individual evaluation; strategic guidelines enhance effectiveness.

Approach Considerations

ARFF vehicles must navigate wreckage and obstructions, requiring personnel guidance for positioning.
Positioning criteria include: proximity for effective stream application, upwind orientation for safe escape routes, and maintaining access to other apparatus.
Repositioning may be necessary to optimize attack effectiveness.

Attack Strategies

Engage the fire attack with the wind direction.
Utilize extinguishing agents as soon as within effective range to protect and isolate the aircraft from fuel fire.
Aim to control 90% of fire intensity within one minute, particularly in critical areas adjacent to the fuselage.
Employ short bursts (10-15 seconds) of extinguishing agents for efficiency and to assess effectiveness.
Turret operations focus on knocking down fuel spills; handlines may be necessary for hard-to-reach areas, occupant protection, and preventing interior fire spread.

Rescue Operations

Rescue efforts should commence immediately upon arrival.
Collaborate in teams of at least two for safety.
Prioritize exits in order: normal, emergency, then forced entry.
Transport occupants to safe, breathable environments.

Control Measures

Use foam to cover spill areas and protect the fuselage, preventing fire spread.
Ensure ongoing availability of water and foam supplies to sustain firefighting efforts.
Regularly reapply AFFF, as it can drain off, allowing vapors to escape; use caution to avoid diluting foam with water.

Off-Airport Emergency Protocols

Initiate fire control and EMS as soon as possible; address scene lighting and extrication.
Protect aircraft fuselage from flames; fire can penetrate fuselage in 30-60 seconds.
Use deck guns for rapid water supply; avoid diluting foam with water.

Interior Attack Considerations

Deploy attack lines inside commercial aircraft quickly, ensuring passenger escape is not obstructed.
Large hoses (1½" minimum) may be required, with backup crews ready for personnel protection.
Provide ventilation using fans or fog streams to counteract smoke inhalation risks.

Security and Scene Safety

Police should secure the incident scene, which is treated as a crime scene initially.
Limit personnel access to preserve evidence; ensure proper command protocols are adhered to.
Disconnect batteries to reduce electrical hazards while working at the scene.

Aircraft Hazards Awareness

Oxygen cylinders, high-pressure lines, and flammable liquids present significant risks.
Cutting into aircraft should focus on areas around windows and doors; use care when using saws due to potential arcing.
Maintain a consistent foam blanket on flammable liquids to suppress ignition.

Fire Investigation Protocol

Document all actions taken at the scene for investigative purposes.
Do not remove items from the crash site until investigators authorize it, as investigations are critical for future safety improvements.

Communication and Coordination

Notify essential personnel and units in the call list during emergencies.
Station 51 ARFF Units may not attend off-airport incidents but can provide technical assistance.
Car 822 must be informed to liaise with FAA for oversight and coordination.
