- When should I evacuate if there's a wildfire nearby?
- As soon as you feel threatened or a voluntary evacuation is suggested — don't wait for a mandatory order. Wildfires move fast and unpredictably with the wind, and roads jam or get cut off once everyone leaves at the same time. Leaving early means clear roads and a calm departure; leaving late can mean gridlock or a blocked route with fire closing in. If you're on the fence, that hesitation is your signal to go now.
- What is defensible space and how much do I need?
- Defensible space is the buffer of cleared, low-flammability area around your home that slows a fire and gives it less fuel to reach the structure — and gives firefighters room to work. CAL FIRE and NFPA guidance points to at least 30 feet: clear dry grass, dead leaves, gutter debris, and woodpiles, and trim low branches. The closest five feet matter most, so keep that zone as bare and non-combustible as possible. It's one of the biggest factors in whether a home survives.
- Do I need a special mask for wildfire smoke?
- Yes — a well-fitting N95 respirator is what actually filters the fine smoke particles that harm your lungs, and for most people that's enough. NIOSH rates an N95 to catch about 95% of those particles. If you want more margin — or a mask you can reuse season after season — a reusable P100 like the GVS Elipse filters even finer, at least 99.97%, though it's an upgrade rather than a requirement. Cloth masks, surgical masks, and bandanas don't block these particles and give a false sense of safety. The mask has to seal against your face to work, which is why most won't fit small children well; for kids, the better protection is staying indoors with clean, filtered air. Keep a few N95s in your kit through fire season.
- How do I keep my indoor air clean during heavy smoke?
- Close all the windows and doors, set your AC or HVAC to recirculate (so it isn't pulling smoky outdoor air in), and run a HEPA air purifier in the room where you spend the most time. Avoid anything that adds particles indoors — no candles, frying, or vacuuming. A simple box-fan-and-furnace-filter setup can stand in for a purifier in a pinch. Keep doing this until the outdoor air-quality reading returns to a healthy range.
- Is it safe to stay home and defend my house from a wildfire?
- For almost everyone, no — leave early instead. Staying to defend a home against wildfire is extremely dangerous, requires real training, equipment, and water supply, and the conditions (heat, smoke, embers, sudden wind shifts) overwhelm people fast. Your life is not worth a structure, and homes that survive usually do so because of defensible space and ember-resistant construction done beforehand, not someone standing there with a hose. Prepare the home, then get yourself and your household out.
