Emergency Management Tips and Reminders
While we have been extremely fortunate concerning the risk for wildfire to date, things could change rapidly with dry, hot weather. Now is the time to inventory your home environment to see what wildfire risks you can mitigate. To that extent, the following information was taken from the National Fire Protection Agency on wildfire preparedness. Additional information about the wildfires and the Firewise program can be found at the NFPA website: https://www.nfpa.org/Public-Education/Fire-causes-and-risks/Wildfire/Preparing-homes-for-wildfire
1. HOME IGNITION ZONES: To increase your home’s chance of surviving a wildfire, choose fire-resistant building materials and limit the amount of flammable vegetation in the three home ignition zones. The zones include the Immediate Zone: (0 to 5 feet around the house), the Intermediate Zone (5 to 30 feet), and the Extended Zone (30 to 100 feet).
2. LANDSCAPING AND MAINTENANCE: To reduce ember ignitions and fire spread, trim branches that overhang the home, porch, and deck and prune branches of large trees up to 6 to 10 feet (depending on their height) from the ground. Remove plants containing resins, oils, and waxes. Use crushed stone or gravel instead of flammable mulches in the Immediate Zone (0 to 5 feet around the house). Keep your landscape in good condition.
3. ROOFING AND VENTS: Class A fire-rated roofing products, such as composite shingles, metal, concrete, and clay tiles, offer the best protection. Inspect shingles or roof tiles and replace or repair those that are loose or missing to prevent ember penetration. Box in eaves, but provide ventilation to prevent condensation and mildew. Roof and attic vents should be screened to prevent ember entry.
4. DECKS AND PORCHES: Never store flammable materials underneath decks or porches. Remove dead vegetation and debris from under decks and porches and between deck board joints.
5. SIDING AND WINDOWS: Embers can collect in small nooks and crannies and ignite combustible materials; radiant heat from flames can crack windows. Use fire-resistant siding such as brick, fibercement, plaster, or stucco, and use dual-pane tempered glass windows.
6. EMERGENCY RESPONDER ACCESS: Ensure your home and neighborhood have legible and clearly marked street names and numbers. Driveways should be at least 12 feet wide with a vertical clearance of 15 feet for emergency vehicle access.
7. FINAL THOUGHTS:
Information concerning face coverings and other protective actions can be found on the Whatcom County Health Department Website.
