Fire Wise

 

 

 

This Multi-Agency National Fire Plan Implementation grant deals with developing local community partnerships for educational opportunities directed towards fire prevention. The highlight of the project is to develop a "Fire Wise Training Trunk" for K-12 education. POCD also partnered with local Fire Districts on preparing a grant proposal to purchase wild fire fighting equipment and install several Dry Hydrants in the more populated areas of the county to increase their response efforts.

Background

Towns and cities are spreading as more and more people move into the countryside. If you live in forest or rangeland, you are part of the growing wildlife/urban interface- where the human environment meets the wild. Fire has been, and will continue to be, a natural part of that environment. Fires can be very destructive, destroy homes and place firefighters at risk. Residents of forested and rangeland areas should view wildfires as common natural occurances-and prepare accordingly..

Two types of wildfire are important to homeowners:

1. Surface fires burn surface litter and plants, shrubs and small trees. This type of fire kills many seedlings, but usually causes minimal damage to mature trees and larger shrubs. Young spruce, fir and hemlock have low fire resistance and can be extremely damaged. Historically, many such areas now occupied by homes had ground fires every 5-15 years

2. Crown fires move through the canopy of a stand of trees, burning from tree crown to tree crown. They can also occur in large stands of sagebrush. These are the most destructive wildfires and kill mature trees, shrubs and move over large areas in short periods of time. Surface fires often become crown fires in stands with a high percentage of spruce, fir and hemlock. These crowns often reach the forest floor and can act as ladders for flames to move higher into the canopy. Crown fires historically occur less frequently than surface fires but are more likely if fire has been suppressed for many years. Fuel accumulates and stands become denser. Prescribed burns and timber harvesting can decrease the fuel load, but these activities are often limited near urban areas.

WILDFIRE PROTECTION DEFENSE

Several steps can be taken to prepare for wildfires and to protect your property against destruction:

Landscaping

The most effective way to increase the protection of your home from wildfire is by creating defensible spaces. Defensible space involves creating increasing resistance to fire in concentric zones around structures (such as your home). A minimum distance of 100-150 feet around your home needs defensible space.

Figure 1 below illustrates these zones.

Zone 1: Moist and trim
Low-growing plants which resist catching fire and provide little fuel are used.
Turf, perennials, annuals and ground cover form a greenbelt that is regularly watered to eliminate dry plant litter. Individual shrubs and trees may be included but must be located at least 10 feet away from the house.
Zone 2: Low and sparse
Slow-growing and drought -resistant shrubs and groundcovers are used to keep fire near ground level. Native vegetation can be retained if it is low, does not accumulate dry, flammable material and is irrigated.
Zone 3: High and clean
Native trees or shrubs are thinned and dry debris on the ground is removed. Overgrowth needs to be removed and trees pruned every 3 to 5 years.
Zone 4: Natural area
Native plants are selectively thinned. If possible, highly flammable vegetation is removed and replaced with less fire-prone species.

Steep slopes or windswept areas need greater defense distance. (see Figure 2 below)

Remember:

All plants will burn if there is enough heat and other conditions are right.

The condition of the plant is more important than the species. The same species may be fire-resistant in some cases and combustible in others depending on its access to water.

Plants that ignite readily and burn intensely (also known as pyrophytes or fire-prone plants) typically share certain characteristics:

  • Water-stressed
  • Accumulate fine, twiggy, dry or dead material
  • Have leaves and wood containing volatile waxes, fats, terpenes or oils
  • Aromatic (crushed leaves have strong odors)
  • Gummy, resinous sap with a strong odor
  • Blade-leaf or needle-leaf evergreens
  • Stiff, leathery, small or fine, lacy leaves
  • Loose or papery bark
  • Flame (not smolder) when preheated and ignited with a match

Fire-resistive plants share these characteristics:

  • High moisture content in leaves
  • Drought tolerant
  • Little or no seasonal accumulation of dead vegetation
  • Low volume of total vegetation
  • Non-resinous woody material
  • Open, loose branching
  • Slow growing

Landscape Maintenance

Regular pruning, mowing, raking and debris removal reduces potential fuel accumulation. The less accumulated plant debris, the slower a fire will spread. Reduce wildfire hazards by:

  • Clean debris from roof and yard several times a year.
  • Remove grassy fuels for 30 feet around all dwellings.
  • Remove highly flammable brush from around each home for not less than 100 feet.
  • Do your best to improve the health and vigor of trees and shrubs around homesites.
  • Don't plant shrubs at the base of structures.
  • Keep tree branches at least 15 feet away from utility lines, chimneys and stove pipes (which should be covered by screens.
  • Store firewood 30-100 feet away from any structure and keep a defensible space around the pile.
  • Remove dead shrubs and trees.
  • Trim shrubs growing 100 feet and further from each house into individual plants.
  • Eliminate "ladder fuel" configurations in vegetation.
  • Prune the base of tree crownds 6 to 15 from the ground.
  • Cut branches that span between tree crowns to 10 feet or more apart.
  • Prune all dead tree branches.

Roads and Signs

Vehicles from firefighting agencies must have adequate access to your property. Your property should be clearly marked with a non-flammable sign in numbers and letters at least 4 inches high on a contrasting background. There should be two ways to access your property in case one route is closed off. Roads should be wide enough for two-way traffic, with vegetation cleared 10 feet from along roadsides and driveways. If a two-way road is not possible, turnouts should be constructed.

Fire equipment has difficulty negotiating excessively steep roads or sharp turns. Bridges should be strong enough to support fire equipment and the water they carry (at least 34,000 pounds or 170 tons) and be identified as being so. If access to your site leads to a cul-de-sac, an adequate turn around radius is needed. A minimum of 50 feet is suggested.

Emergency Water Supplies

If you don't have enough water to fight a fire, consider developing an emergency water supply such as an additional well, pond, cistern, swimming pool or tank. 25,000 gallons of water should be available for emergency backup. Make sure water supplies are clearly marked and accessible to fire trucks. Leave at least 16 feet of access to a water source. Get a gas-powered generator to provide power to the pump of a well which is used as the water source in case you lose electrical service.

Building Materials

If you have not built yet, try to place structures on flat ground and avoid draws. Use fire resistant materials whenever possible such as tile or fiberglass roofing materials and brick or stucco walls.Line the undersides of decks and porches with a nonflammable material. Double pane windows and protective shutters or window treatments will help insulate the inside of the house from the heat of a fire, lessening the chance of the interior becoming overheated and igniting. Make sure the chimneys are screened and build covers for any openings in the attic and basement. If possible have power lines buried to protect them from fire and to prevent the ignition of vegetation. If lines are not buried, make sure trees and branches are trimmed 10 to 15 feet away from lines. 

Fire Safe Inside

The inside of your home should also be firesafe:

  • Know your fire protection district and post the phone number by all telephones.
  • Install smoke detectors and replace batteries twice a year (when you change the time in the spring and fall).
  • Consider installing and indoor sprinkler system.
  • Locate several fire extinguishers throughout the house and garage. Have them serviced yearly to make sure they are fully charged. Know how they work and which types work on which types of fires.
  • Clean chimneys before cold weather sets in and as needed as creosote builds up. Some fire departments offer free use of a chimney brush.
  • Establish and escape plan and practice fire drills with your family.
  • Place all important documents and valuables in a fire-safe box and keep it in an accessible location.
  • Pre-plan and emergency community fire procedure with neighbors.
  • Prepare a fire kit. Include 3 days food and water, shovel, rake, hoe, bucket, sprinkler, hose, a ladder long enough to reach the roof, and protective clothing such as goggles, gloves, a long-sleeved shirt, pants and boots.

STEPS FOR EVACUATION WHEN A WILDFIRE THREATENS

In the event of a wildfire, call 911 or your fire protection district. Click here for a local resource list. Put valuables and pets in the car, park in the direction of escape, and leave the key in the ignition. If there is time take the following steps:

  1. Wear protective clothing
  2. Close up the house and disconnect electric garage door openers.
  3. Cover attic and basement vents.
  4. Fill all available containers with water.
  5. Put up a ladder to the roof opposite the approaching fire and put a sprinkler on the roof.
  6. Get the emergency generator ready to run the pump in the well.
  7. Shut off the gas supply.
  8. Turn on all indoor and outdoor lights to make your house easier for firefighters to find in the dark.
  9. Take down flammable window treatments; close nonflammable window treatments such as metal blinds.
  10. Arrange temporary housing at the home of a friend or relative who is outside the threatened area.
