Wildfire Smoke and Safety Awareness Tips

Wildfire Safety and Smoke Awareness
Protect Yourself and Others from Wildfire Smoke

Each year, wildfires threaten people living near wild land areas or using recreational facilities in wilderness areas. Wildfire smoke can affect your health. When wildfires burn in your area, they produce smoke that may reach your community. Smoke from wildfires is a mixture of gases and fine particles from burning trees and other plant materials. Smoke can hurt your eyes, irritate your respiratory system, and worsen chronic heart and lung diseases.

Who is at greatest risk from wildfire smoke?

· People who have heart or lung diseases, like congestive heart failure, angina, chronic obstructive pulmonary disease (including emphysema), or asthma, are at higher risk from wildfire smoke. In general, people with these conditions are at higher risk of having health problems than healthy people.

· Older adults are more likely to be affected by smoke. This may be due to their increased risk of heart and lung diseases.

· Children are more likely to be affected by health threats from smoke. Children’s airways are still developing and they breathe more air per pound of body weight than adults. In addition, children often spend more time outdoors engaged in activity and play.

What are some of the symptoms related to wildfire smoke?
  • Eye, nose and/or throat irritation–runny eyes and/or nose.
  • Coughing, sore throat.
  • Trouble breathing or tightness of the chest, which may be symptoms of a health emergency.
  • The onset of symptoms related to pre-existing respiratory ailments like asthma or emphysema.
  • Especially following days or weeks of smoke exposure, increased short-term likelihood of getting a cold or having similar symptoms of less effective immune responses.
  • If symptoms persist or are severe, contact your primary health care provider.

Take steps to decrease your risk from wildfire smoke.

· Check local air quality reports. Listen and watch for news or health warnings about smoke. Find out if your community provides reports about the U.S. Environmental Protection Agency’s Air Quality Index (AQI). In addition, pay attention to public health messages about taking safety measures. The table below shows how the system is applied:

Air Quality Category
(AQI)
24-Hr PM2.5
(µg/m3)1
1-Hr PM2.5
(µg/m3)2
Visibility
(miles)3
Good 0.0 – 22.0 0.0 – 40.0 10 or more miles
Moderate 15.5 – 40.4 40.1 – 80.0 5-10 miles
Sensitive Groups 40.5 – 65.4 80.1 – 175.0 3-5 miles
Unhealthy 65.5 – 150.4 175.0 – 300.0 1.5 – 3 miles
Very Unhealthy 150.5 – 250.4 300.1 – 500.0 1. – 1.5 miles
Hazardous ≥250.5 ≥500.1 ≤1 mile

AQI Key:
Good: 0-50
Moderate: 51-100
Unhealthy (for Sensitive Groups): 101-150
Unhealthy: 151-200
Very Unhealthy: 201-250
Hazardous: 251-300

· Consult local visibility guides if they are available. Some communities have monitors that measure the amount of particles that are in the air. In the western part of the United States, some states and communities provide guidelines to help people determine if there are high levels of particulates in the air by how far they can see.

· Keep indoor air as clean as possible if you are advised to stay indoors. Keep windows and doors closed. Run an air conditioner if you have one, but keep the fresh-air intake closed and the filter clean to prevent outdoor smoke from getting inside. If you do not have an air conditioner and it is too warm to stay inside with the windows closed, seek shelter in a designated evacuation center or away from the affected area.

·

Avoid activities that increase indoor pollution. Burning candles, fireplaces, or gas stoves can increase indoor pollution. Vacuuming stirs up particles already inside your home, contributing to indoor pollution. Smoking also puts even more pollution into the air.

· Prevent wildfires from starting. Prepare, build, maintain and extinguish campfires safely. Comply with local regulations if you plan to burn trash or debris. Check with your local fire department to be sure the weather is safe enough for burning.

· Follow the advice of your doctor or other healthcare provider about medicines and about your respiratory management plan if you have asthma or another lung disease. Consider evacuating the area if you are having trouble breathing. Call for further advice if your symptoms worsen.

· Do not rely on dust masks for protection. Paper “comfort” or “dust” masks commonly found at hardware stores are designed to trap large particles, such as sawdust. These masks will not protect your lungs from the small particles found in wildfire smoke.

· Evacuate from the path of wildfires. Listen to the news to learn about current evacuation orders. Follow the instructions of local officials about when and where to evacuate. Take only essential items with you. Follow designated evacuation routes—others may be blocked—and expect heavy traffic.

What are the known chemical components of smoke from wildfires?

  • Particulate matter – coarse visible and fine invisible particles including soot and ash that can reach deep into the lungs and may contain irritating and cancer-causing compounds.
  • Polynuclear aromatic hydrocarbons – a class of organic compounds found on the particulate matter from forest fires, wood stoves, and fireplaces, some of which may be carcinogenic with extended exposure.
  • Carbon monoxide – a colorless, odorless, toxic gas produced in highest amounts from smoldering forest fires. Firefighters working near the fire are at greatest risk for high doses of carbon monoxide. Areas even a few hundred yards downwind of the fire experiencing high particulate smoke levels typically do not have high levels of carbon monoxide. Signs of high carbon monoxide levels in the blood include headaches, dizziness, nausea, and decreased mental functioning.
  • Aldehydes – compounds that are extremely irritating to the eyes and mucous membranes of the mouth and nose. Some like formaldehyde are carcinogenic, while others like acrolein can injure lung tissue.
  • Volatile organic compounds – strong irritants, some of which are carcinogenic.
  • And many other chemical components…

Wildfire Safety Tips – Are You Prepared?

The wildfires potential is extreme in our area. The Little Bear fire burning near Ruidoso has devastated homes, cabins and produced lots of smoke covering eastern NM. Additionally with the wind and heat there is a very real danger of wildfire.

Wildfires often begin unnoticed. They spread quickly, igniting grass, brush, trees, and homes. Reduce your risk by preparing now – before wildfire strikes. Meet with your family to decide what to do and where to go if wildfires threaten your area. Follow the steps listed below to protect your family, home, and property.

Practice Wildfire Safety

People start most wildfires …find out how you can promote and practice wildfire safety.

  • Contact your local fire department, health department, Bureau of Land Management or forestry office for information on fire laws.
  • Make sure that fire vehicles can get to your home. Clearly mark all driveway entrances and display your name and address.
  • Report hazardous conditions that could cause a wildfire.
  • Teach children about fire safety. Keep matches out of their reach.
  • Post fire emergency telephone numbers.
  • Ensure adequate accessibility by large fire vehicles to your property.
  • Plan several escape routes away from your home – by car and by foot.
  • Talk to your neighbors about wildfire safety. Plan how the neighborhood could work together after a wildfire. Make a list of your neighbors’ skills such as medical or technical. Consider how you could help neighbors who have special needs such as elderly or disabled persons. Make plans to take care of children who may be on their own if parents can’t get home.

Before Wildfire Threatens

Design and landscape your home with wildfire safety in mind. Select materials and plants that can help contain fire rather than fuel it. Use fire-resistant or noncombustible materials on the roof and exterior structure of the dwelling, or treat wood or combustible material used in roofs, siding, decking, or trim with fire-retardant chemicals evaluated by a nationally recognized laboratory, such as Underwriters Laboratories (UL). Plant fire-resistant shrubs and trees. For example, hardwood trees are less flammable than pine, evergreen, eucalyptus or fir trees.

Your best resource for proper planning is www.firewise.org which has outstanding information used daily by residents, property owners, fire departments, community planners, builders, public policy officials, water authorities, architects and others to assure safety from fire – it really works. Firewise workshops are offered for free all across the Nation in communities large and small and free Firewise materials can be obtained easily by anyone interested.

Create a 30- to 100-foot safety zone around your home

Within this area, you can take steps to reduce potential exposure to flames and radiant heat. Homes built in pine forests should have a minimum safety zone of 100 feet. If your home sits on a steep slope, standard protective measures may not suffice. Contact your local fire department or forestry office for additional information.

Create a 30-foot safety zone around the house.
Keep the volume of vegetation in this zone to a minimum. If you live on a hill, extend the zone on the downhill side. Fire spreads rapidly uphill. The steeper the slope, the more open space you will need to protect your home. Swimming pools and patios can be a safety zone and stone walls can act as heat shields and deflect flames. In this zone, you should also do the following:

  • Remove vines from the walls of the house.
  • Move shrubs and other landscaping away from the sides of the house.
  • Prune branches and shrubs within 15 feet of chimneys and stove pipes.
  • Remove tree limbs within 15 feet of the ground.
  • Thin a 15-foot space between tree crowns.
  • Replace highly flammable vegetation such as pine, eucalyptus, junipers and fir trees with lower growing, less flammable species. Check with your local fire department or garden store for suggestions.
  • Replace vegetation that has living or dead branches from the ground-level up (these act as ladder fuels for the approaching fire).
  • Cut the lawn often keeping the grass at a maximum of 2 inches. Watch grass and other vegetation near the driveway, a source of ignition from automobile exhaust systems.
  • Clear the area of leaves, brush, evergreen cones, dead limbs and fallen trees.

Create a second zone at least 100 feet around the house.
This zone should begin about 30 feet from the house and extend to at least 100 feet. In this zone, reduce or replace as much of the most flammable vegetation as possible. If you live on a hill, you may need to extend the zone for several hundred feet to provide the desired level of safety.

Clear all combustibles within 30 feet of any structure.

  • Install electrical lines underground, if possible
  • Ask the power company to clear branches from power lines.
  • Avoid using bark and wood chip mulch
  • Stack firewood 100 feet away and uphill from any structure.
  • Store combustible or flammable materials in approved safety containers and keep them away from the house.
  • Keep the gas grill and propane tank at least 15 feet from any structure. Clear an area 15 feet around the grill. Place a 1/4 inch mesh screen over the grill. Always use the grill cautiously but refrain from using it all during high risk times.

Review your homeowner’s insurance policy and also prepare/update a list of your home’s contents.

Protect your home

Remove debris from under sun decks and porches.
Any porch, balcony or overhang with exposed space underneath is fuel for an approaching fire. Overhangs ignite easily by flying embers and by the heat and fire that get trapped underneath. If vegetation is allowed to grow underneath or if the space is used for storage, the hazard is increased significantly. Clear leaves, trash and other combustible materials away from underneath sun decks and porches. Extend 1/2-inch mesh screen from all overhangs down to the ground. Enclose wooden stilts with non-combustible material such as concrete, brick, rock, stucco or metal. Use non-combustible patio furniture and covers. If you’re planning a porch or sun deck, use non-combustible or fire-resistant materials. If possible, build the structure to the ground so that there is no space underneath.

Enclose eaves and overhangs.
Like porches and balconies, eaves trap the heat rising along the exterior siding. Enclose all eaves to reduce the hazard.

Cover house vents with wire mesh.
Any attic vent, soffit vent, louver or other opening can allow embers and flaming debris to enter a home and ignite it. Cover all openings with 1/4 inch or smaller corrosion-resistant wire mesh. If you’re designing louvers, place them in the vertical wall rather than the soffit of the overhang.

Install spark arrestors in chimneys and stovepipes.
Chimneys create a hazard when embers escape through the top. To prevent this, install spark arrestors on all chimneys, stovepipes and vents for fuel-burning heaters. Use spark arrestors made of 12-gauge welded or woven wire mesh screen with openings 1/2 inch across. Ask your fire department for exact specifications. If you’re building a chimney, use non-combustible materials and make sure the top of the chimney is at least two feet higher than any obstruction within 10 feet of the chimney. Keep the chimney clean.

Use fire resistant siding.
Use fire resistant materials in the siding of your home, such as stucco, metal, brick, cement shingles, concrete and rock. You can treat wood siding with UL-approved fire retardant chemicals, but the treatment and protection are not permanent.

Choose safety glass for windows and sliding glass doors.
Windows allow radiated heat to pass through and ignite combustible materials inside. The larger the pane of glass, the more vulnerable it is to fire. Dual- or triple-pane thermal glass, and fire resistant shutters or drapes, help reduce the wildfire risk. You can also install non-combustible awnings to shield windows and use shatter-resistant glazing such as tempered or wireglass.

Other safety measures to consider at the time of construction or remodeling.

  • Choose locations wisely; canyon and slope locations increase the risk of exposure to wild land fires.
  • Use fire-resistant materials when building, renovating, or retrofitting structures.
  • Avoid designs that include wooden decks and patios.
  • Use non-combustible materials for the roof.
  • The roof is especially vulnerable in a wildfire. Embers and flaming debris can travel great distances, land on your roof and start a new fire. Avoid flammable roofing materials such as wood, shake and shingle. Materials that are more fire resistant include single ply membranes, fiberglass shingles, slate, metal, clay and concrete tile. Clear gutters of leaves and debris.
  • Inspect chimneys at least twice a year. Clean them at least once a year. Keep the dampers in good working order. Equip chimneys and stovepipes with a spark arrester that meets the requirements of National Fire Protection Association Standard 211. (Contact your local fire department for exact specifications.)
  • Use 1/8-inch mesh screen beneath porches, decks, floor areas, and the home itself. Also, screen openings to floors, roof and attic.
  • Install a dual-sensor smoke alarm on each level of your home, especially near bedrooms; test monthly and change the batteries at least once each year.
  • Teach each family member how to use a fire extinguisher (ABC type) and show them where it’s kept.
  • Keep handy household items that can be used as fire tools: a rake, axe, handsaw or chain saw, bucket and shovel.
  • Keep a ladder that will reach the roof.
  • Consider installing protective shutters or heavy fire-resistant drapes.

Plan your water needs

  • Identify and maintain an adequate outside water source such as a small pond, cistern, well, swimming pool, or hydrant.
  • Have a garden hose that is long enough to reach any area of the home and other structures on the property.
  • Install freeze-proof exterior water outlets on at least two sides of the home and near other structures on the property. Install additional outlets at least 50 feet from the home.
  • Consider obtaining a portable gasoline powered pump in case electrical power is cut off.

When Wildfire Threatens

If you are warned that a wildfire is threatening your area, listen to your battery-operated radio for reports and evacuation information. Follow the instructions of local officials.

  • Back your car into the garage or park it in an open space facing the direction of escape. Shut doors and roll up windows. Leave the key in the ignition. Close garage windows and doors, but leave them unlocked. Disconnect automatic garage door openers.
  • Confine pets to one room. Make plans to care for your pets in case you must evacuate.
  • Arrange temporary housing at a friend or relative’s home outside the threatened area.

If advised to evacuate, do so immediately

  • Wear protective clothing – sturdy shoes, cotton or woolen clothing, long pants, a long-sleeved shirt, gloves, and a handkerchief to protect your face.
  • Take your Disaster Supplies Kit.
  • Lock your home.
  • Tell someone when you left and where you are going.
  • Choose a route away from fire hazards. Watch for changes in the speed and direction of fire and smoke.

If you’re sure you have time, take steps to protect your home

Inside:

  • Close windows, vents, doors, blinds, or noncombustible window coverings and heavy drapes. Remove lightweight curtains.
  • Shut off all utilities if possible, including bottled gas.
  • Open fireplace damper. Close fireplace screens.
  • Move flammable furniture into the center of the home away from windows and sliding glass doors.
  • Turn on a light in each room to increase the visibility of your home in heavy smoke.

Outside:

  • Seal attic and ground vents with precut noncombustible coverings.
  • Turn off propane tanks.
  • Place combustible patio furniture inside.
  • Connect the garden hose to outside taps.
  • Set up a portable gasoline-powered pump.
  • Place lawn sprinklers on the roof and near aboveground fuel tanks. Wetting the roof may help if it is shake-shingled.
  • Wet or remove shrubs within 15 feet of the home.
  • Gather fire tools.

Emergency Supplies

When wildfire threatens, you won’t have time to shop or search for supplies. Assemble a Disaster Supplies Kit with items you may need if advised to evacuate. Store these supplies in sturdy, easy-to-carry containers such as backpacks, duffle bags, or trash containers.

Include:

  • A three-day supply of water (one gallon per person per day) and food that won’t spoil.
  • One change of clothing and footwear per person and one blanket or sleeping bag per person.
  • A first aid kit that includes your family’s prescription medications.
  • Emergency tools including a battery-powered radio, flashlight, and plenty of extra batteries.
  • An extra set of car keys and a credit card, cash, or traveler’s checks.
  • Sanitation supplies.
  • Special items for infant, elderly, or disabled family members.
  • An extra pair of eye-glasses.
  • Keep important family documents in a waterproof container. Assemble a smaller version of your kit to keep in the trunk of your car.

Create a Family Disaster Plan

Wildfire and other types of disasters – hurricane, flood, tornado, earthquake, hazardous materials spill, winter storm – can strike quickly and without warning. You can cope with disaster by preparing in advance and working together. Meet with your family to create a disaster plan. To get started…

Contact your local Emergency Management Agency or your local American Red Cross chapter

  • Find out about the hazards in your community.
  • Ask how you would be warned.
  • Find out how to prepare for each type of disaster.

Meet with your family

  • Discuss the types of disasters that could occur.
  • Explain how to prepare and respond to each type of disaster.
  • Discuss where to go and what to bring if advised to evacuate.
  • Practice what you have discussed.

Plan how your family will stay in contact if separated by disaster

  • Pick two meeting places:
    1. a place a safe distance from your home in case of a home fire.
    2. a place outside your neighborhood in case you can’t return home.
  • Choose an out-of-state friend as a “check-in contact” for everyone to call.

Complete these steps

  • Post emergency telephone numbers by every phone.
  • Show responsible family members how and when to shut off water, gas, and electricity at main switches.
  • Contact your local fire department to learn about home fire hazards.
  • Learn first aid and CPR. Contact me for the next class March 18, 2011 or your local American Red Cross chapter for information and training.

What to do After a Wildfire

  • Check the roof immediately. Put out any roof fires, sparks or embers. Check the attic for hidden burning sparks.
  • If you have a fire, get your neighbors to help fight it.
  • The water you put into your pool or hot tub and other containers will come in handy now. If the power is out, try connecting a hose to the outlet on your water heater.
  • For several hours after the fire, maintain a “fire watch.” Re-check for smoke and sparks throughout the house.

Practice and review these steps!
