    Weather's Impact on Fire

    Weather conditions, especially wind and humidity, play a significant role in how quickly and intensely a fire spreads.

    Fire Behavior in Hot Conditions

    Hot, dry conditions create ideal conditions for quick fire spread. Even slightly lower humidity intensifies the fire.

    Peak Fire Danger Time

    The time between 12:00 and 16:00 is typically when fire danger is at its highest.

    Fire's Speed and Convection

    Fires can move faster than a person can run, creating unpredictable air currents and creating spot fires ahead of the main blaze.

    Study Notes

    Weather Considerations

    • Awareness of shifting weather conditions is crucial; local winds and humidity significantly impact fire behavior.
    • Hot, dry conditions can lead to rapid fire spread; even a small decrease in humidity increases fire intensity.
    • Peak fire danger typically occurs between 12:00 and 16:00.
    • Fire can move faster than a person can run and create dangerous convection currents causing erratic behavior and spot fires ahead of the fire front.

    Fuel Characteristics

    • Tulsa's fire fuels are light and burn rapidly, necessitating close monitoring post-fire to eliminate embers from heavier fuels.
    • Mop-up operations focus on preventing embers from igniting new fuel sources.

    Topography Effects

    • Fires burn uphill more quickly than downhill, creating spot fires on the descent.
    • Access challenges arise from rough terrain; companies need to assess fuel, topography, and exposure risks to structures.
    • Important considerations include assessing the location of access roads and natural fire breaks.

    Command Structure

    • Establish a safe command post and divisions quickly; it should remain stationary with potential helicopter access.
    • Command post location is pivotal to facilitate operations regardless of fire direction changes.

    Tactical and Strategic Approaches

    • Brush fires can spread over vast areas; strategic attack positions are critical.
    • Prioritize aggressive action to halt the fire's progress or protect exposures if immediate control isn't viable.
    • Direct water application is the quickest control method; other defensive strategies may be necessary when direct attack isn't feasible.
    • Protect structures and allow the fire to burn to a more manageable location when needed.
    • In water-scarce situations, target burning materials instead of pre-wetting unburned fuel.

    Resource Management

    • Maintain wet conditions for seriously exposed structures.
    • Structural companies should be deployed for exposure protection; grass rigs can remain mobile.
    • Utilize natural fire barriers (sandy washes, roads, trails) during large grass fires.
    • Class A foam is effective for both suppression and exposure protection; use a 1% mixture in direct attacks and higher concentrations for mop-ups.

    Safety and Precautions

    • Back-firing is risky and should be a last resort due to terrain and fire size.
    • Adhere to standard firefighting orders for safety:
      • Stay informed about weather and fire behavior; identify escape routes and safety zones.
      • Maintain clear and prompt communication; ensure instructions are understood.
      • Act aggressively, prioritizing safety at all times.

    Warning Situations

    • Be vigilant for critical situations indicating potential danger, such as unscouted fire areas and unfamiliar terrain conditions.
    • Specific cautions include fighting fires in darkness, not having a clear anchor point, and being unaware of fire behavior influencing factors.

    Critical Firefighting Concepts

    • Approach fires from burned areas (the black).
    • Use appropriate personal protective equipment (PPE).
    • Operate in teams of at least two for safety.
    • Secure enough support early on and utilize a spotter in challenging terrain.
