How to Prepare for a Wildfire: A Calm Checklist

Wildfire coverage is usually walls of flame and helicopter shots. Useful for ratings, useless for your household. The calm reality is that wildfire readiness is mostly boring, done-in-advance work, built on guidance from Cal Fire, Ready.gov and the Red Cross.

Two ideas carry most of the safety: embers, not the wall of flame, burn down most homes (they blow in and land on roofs, vents and dry leaves), and the people who survive leave early. The firefighting world sums it up as Ready, Set, Go.

The quick version (5-minute scan)

• Defensible space: clear dead leaves and flammable stuff in the first 5 feet around the house.
• Harden the home: clear gutters and roof, screen vents against embers.
• Go-bag ready: documents, meds, chargers, N95s, packed and by the door in fire season.
• Two ways out: know two routes, sign up for local evacuation alerts.
• Leave early: if it feels wrong, go before the order. Once ordered, go immediately.
• Smoke plan: N95/P100 masks and one room you can keep clean-air.

1. Ready — defensible space and a hardened home

Most homes ignite from embers that travel well ahead of the fire. So the highest-value work is denying them fuel:

• 0–5 ft (the ember zone): keep it lean — no bark mulch, firewood, dry plants or doormats against the walls. This strip matters most.
• 5–30 ft: "lean, clean and green" — trim, space out plants, mow, remove dead vegetation.
• The house itself: clear leaves from roof and gutters, screen vents with fine metal mesh, and keep flammables out from under decks.

2. Set — the go-bag and your alerts

During fire season, keep a go-bag packed: IDs and insurance in a waterproof bag, a week of medications, phone chargers and a power bank, N95 masks, water, and a change of clothes. Sign up for your county's emergency alerts, agree a family meeting point, and know two ways out of your area in case one is blocked — see evacuation route planning.

3. Go — leave early, not late

This is the one that saves lives. Wildfires move fast and unpredictably, and roads jam quickly. If you feel unsafe, leave before any official order. Once an evacuation is ordered, go immediately — don't stay to wet the roof or pack more. A clear decision made early beats a frantic one in smoke and traffic. Our stay-or-evacuate guide helps you set the trigger in advance.

4. Smoke is a hazard even far from the flames

Wildfire smoke can make air dangerous hundreds of miles away. Check your local air quality (AQI) on AirNow, and when it's bad:

• Stay indoors, windows and doors closed; run AC on recirculate if you have it.
• A real N95 or P100 respirator helps with particulates — cloth and surgical masks do not.
• Create one clean-air room: close it up and run a HEPA air purifier (or a box-fan filter) — see keeping a room livable.

5. After the fire

• Don't return until officials say it's safe — hotspots and downed lines remain for days.
• Ash is hazardous: wear an N95 and gloves when cleaning, don't let kids play in it.
• Burned slopes bring flash floods and debris flows in the next rains — stay alert if you're downhill of a burn scar.

Wildfire is a "slow then fast" disaster — months to prepare, minutes to act. The prep is calm; the leaving is decisive. Pair this with a plan everyone knows: family emergency plan.

Frequently asked questions

What is defensible space?
A buffer you create around your home by clearing flammable vegetation and debris — most critically the first 5 feet — so embers and flames have less to catch. (Cal Fire)

When should I evacuate during a wildfire?
Early. If you feel unsafe, leave before an official order; once one is issued, go immediately. Wildfires and traffic move fast. (Ready.gov)

Do masks help against wildfire smoke?
A properly fitted N95 or P100 respirator helps filter the fine particles in smoke. Cloth and surgical masks don't. (CDC)
