Wildland Urban Interface – Structure Protection

 

The primary consideration of any operation is to assure firefighter and public safety. It is a must to assess potential fire behavior, ingress/egress routes, nature of the threat, hazardous materials, and available water supplies before engaging in the protection of any structure.

Factors that may make an attempt to save a structure too dangerous include:

  • The fire is making a sustained run and there is little or no clearance between the structure and the fuel.
  • The fire behavior is extreme; spot fires are numerous and the spread is outpacing containment.
  • Water supply will not last as long as the threat of the fire.
  • The fire intensity dictates that you leave the fire area immediately.
  • The structure is constructed of wood and has a wood shake roof.
  • The roof of the structure is more than one-quarter involved.
  • There is fire inside of the structure, or windows are broken and there is no way to quickly repair them.
  • You cannot safely remain at the structure because your escape route could become unusable.

When implementing a plan to protect structures, consider the following:

  • Do not enter a burning structure unless you are trained, equipped, and authorized. Firefighter safety and survival is the number one priority.
  • Always stay mobile and wear all personal protective equipment (PPE).
  • Back in equipment to allow for a quick escape.
  • Coil a short, charged line with a fog nozzle on your engine for safety and quick knockdown capability.
  • Don’t make long hose lays.
  • Reserve at least 100 gallons of water in your tank.
  • Check the road system before the fire approaches. Know bridge limits, alternate access routes, and turnarounds for your vehicle and other support vehicles.
  • Determine if residents are home. Leave the inside and outside lights on, regardless of the time of day. Close the garage door.
  • Place the owners’ ladder at a corner of the home on the side with the least fire threat.
  • Coil and charge garden hoses.
  • Check and mark hazardous materials (e.g., Liquefied Propane Gas [LPG] tanks, pesticides, and paint storage.

ETC Equipment Bulletin: 25-004 NEW Aquatic Invasive Species – Golden Mussels

Date: July 29, 2025
Questions?  Please contact:
Equipment Technology Committee
 

The Equipment Technology Committee (ETC) issued Equipment Bulletin: 25-004, notifying the wildland fire community about a newly discovered invasive species and actions to take if found. Golden mussels, a highly invasive species recently identified in California, pose a significant risk to native ecosystems, infrastructure, and fire equipment. These mussels rapidly colonize hard and soft surfaces, including aquatic plants and fire equipment, clogging pipes, fouling motors, disrupting water systems, and impacting native species.

To help prevent their spread, fire personnel must follow the decontamination procedures outlined in the NWCG Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations, PMS 444. Additionally, report any sightings immediately to your Lead Resource Advisor and include clear, close-up photos and location details.

Read the complete ETC Equipment Bulletin: 25-004 to learn more.
