Purpose

This page helps you recognize the life-threatening wildfire risks that kill people most often.

It focuses on what NOT to do, and when to leave early.

Scope

This is guidance for households.

It is not firefighting advice.

Do not stay to “defend” a home unless authorities specifically direct you to shelter and it is clearly safer than evacuation.

Fast Facts That Could Save Your Life

• Wildfires can spread quickly and change direction fast with wind shifts.

• Embers and smoke can threaten you even when the main fire is not nearby.

• Evacuation delays are a major cause of preventable deaths and entrapments.

• Smoke exposure (fine particles / PM2.5) is a serious health risk, especially for children, older adults, pregnant people, and anyone with heart or lung disease.

⚠️ Why Wildfires Are So Dangerous

• Wind-driven change.

• Ember-driven ignition (home ignites even if flames never reach it).

• Toxic smoke and low visibility.

• Infrastructure disruption (power, roads, communications).

• Fast-moving evacuation conditions (traffic, closures, reduced visibility).

The Deadly Mistakes

• Waiting to “see what happens” when conditions are worsening or alerts are issued.

• Driving through smoke, flames, or areas with downed power lines.

• Ignoring evacuation routes and improvising shortcuts.

• Using fans or bringing smoky air inside instead of controlling indoor air.

• Leaving generators, BBQs, or fuel-powered devices in unsafe locations or near openings (carbon monoxide and fire risk).

Who Is Most at Risk

• People in forest interface / grassland interface communities.

• Anyone with limited evacuation routes (one bridge, one highway).

• People who need time to move (children, seniors, disabilities, medical equipment users).

• Homes with heavy combustible materials close to the structure.

Home Buffer Zones (Reducing “Home Ignition” Risk)

Warning

Do not attempt complex construction changes based on a web page.

Follow your local fire authority and local building code requirements.

The core idea:

The closer fuels are to your home, the more likely embers and radiant heat will ignite it.

Common government guidance uses distance “zones” around the home:

• Immediate zone close to the home is treated as a non-combustible / fire-resistant area.

• A wider zone focuses on reducing easily ignited fuels and preventing fire from “laddering” into tree canopies.

Two government examples you can safely reference:

• British Columbia guidance describes a non-combustible zone of 0–1.5 metres around the home and attachments.

• U.S. federal guidance commonly references reducing flammable materials for at least 30 feet around the home.

High-liability note:

We are not listing “how to landscape” steps here.

Use your local wildfire program checklist for exact requirements.

Evacuate Early vs Shelter

Authority Override

If you receive an Evacuation Order, leave.

If you receive an Evacuation Alert, prepare to leave immediately and be ready to go with minutes’ notice.

Evacuate Immediately If

• You are under an evacuation order or told to leave by authorities.

• Fire is approaching and you have time to leave safely.

• Smoke is worsening rapidly and visibility is dropping.

• Your route out may close soon (wind shift, highway closures).

Shelter Only If

• Authorities advise sheltering and evacuation routes are unsafe.

• You can control indoor air quality and heat safely.

Vehicle “Go Now” Readiness (Low-Risk, High-Value)

What NOT to do:

• Do not leave your vehicle low on fuel during wildfire season if you live in a risk area.

Government guidance examples:

• Keep your vehicle fueled so evacuation is not delayed by refuelling.

• If evacuating, keep car windows closed, and follow official routes and closures.

Wildfire Smoke: Protecting Health (What NOT to do)

What NOT to do:

• Do not treat wildfire smoke like “normal campfire smoke.”

• Do not keep windows open during heavy smoke to “air it out.”

• Do not do strenuous outdoor activity during heavy smoke if you have symptoms or are high-risk.

Safer, government-aligned approach:

• Seal windows and doors as advised and reduce indoor smoke entry.

• Use properly sized air filtration if available and monitor official air quality guidance.

• If you must be outdoors in smoke, a well-fitting NIOSH-certified N95 (or equivalent) reduces exposure to PM2.5, but it is not perfect protection.

Wildfire “Leave Fast” Essentials (Household Level)

Goal

Leave with the items that prevent death or medical crisis.

Everything else is secondary.

• IDs and essential documents (waterproof)

• Medications and critical medical supplies

• Phone + power bank

• Keys + wallet

• Water and basic food

• Child / elder essentials

• Pet leash / carrier / food

• Respiratory protection for smoke (N95 or equivalent)
