How to Prepare for a Wildfire: Safety and Evacuation Guide

In 2024, the National Interagency Fire Center recorded 64,897 wildfires that burned nearly 8.9 million acres across the United States. In 2025, 18,385 structures were destroyed, with Southern California accounting for a large share of the losses.

Wildfires can occur throughout the year, although the timing and severity of risk vary significantly by region, vegetation, weather, and drought conditions. Millions of Americans live in wildland-urban interface communities, where homes and other development meet or intermingle with fire-prone vegetation.

This guide explains how to prepare for a wildfire, create defensible space, build a fire evacuation plan, protect indoor air quality and prepare for power outages. Backup power can support selected household needs, but it must never delay evacuation or replace official emergency instructions.

Key Takeaways

• Wildfire activity often increases during warmer and drier months in the West, but destructive fires can occur during any season when fuels and weather conditions align.

• Conditions can change quickly. Prepare a go-bag, identify evacuation routes and keep your vehicle ready before a fire threatens the area.

• A cleaner-air room is intended for smoke events when the home is not under an evacuation order or direct fire threat. If authorities tell you to leave, evacuate immediately.

• Public Safety Power Shutoffs and fire-related infrastructure damage may interrupt electricity. Calculate essential loads and prepare backup power before an outage occurs.

• Fuel-burning generators must never be operated inside a home, garage or other enclosed or partially enclosed space. Portable power stations produce no combustion exhaust during operation but must still be kept dry, ventilated and away from heat or fire.

• The BLUETTI Elite 300 provides 3,014.4 Wh of capacity and 2,400 W of rated AC output. Actual runtime depends on measured load, conversion losses, appliance cycling and reserve capacity.

Understanding Wildfire Risk

Longer and More Variable Fire Seasons

Wildfire activity often increases during the warmer and drier months across much of the West. However, regional timing differs, and destructive fires can occur during winter or spring when dry fuels, low humidity and strong winds combine.

The Southeast also experiences significant seasonal wildfire activity, often during dry periods in late winter and spring. Households should follow local fire-weather forecasts rather than relying on one national wildfire season.

Wildland-urban interface communities face two related risks: direct exposure to wildfire and power outages caused by damaged infrastructure or utility-initiated shutoffs during extreme fire weather.

Two Scenarios Every Household Should Plan For

Evacuation: When local authorities issue an evacuation order or recommend early departure for your zone, leave promptly using the designated route. Essential medications, documents, communication equipment and pet supplies should already be packed.

Smoke sheltering: During smoke events without an evacuation order or direct fire threat, residents may need to remain indoors and reduce smoke infiltration. Indoor filtration does not make a home safe from an approaching wildfire.

Before a Wildfire: The Preparation Phase

Create Defensible Space

Defensible-space requirements vary by state, county and community. Follow local fire-code requirements and recommendations from the relevant fire authority.

A widely supported approach includes:

• Immediate zone, approximately 0–5 feet from the structure: Remove combustible mulch, dead vegetation, leaves, firewood and other materials that could ignite from windborne embers. Use non-combustible surfaces where practical.

• Intermediate zone, approximately 5–30 feet: Maintain vegetation, remove dead branches, keep grass short and separate plants to reduce the ability of fire to travel toward the home.

• Extended zone, approximately 30–100 feet or to the property boundary: Reduce continuous fuels, remove ladder fuels and maintain spacing between trees and shrubs according to local guidance.

Clean roofs, gutters, decks and the areas beneath decks regularly. Windborne embers can travel well ahead of the main fire and ignite leaves, mulch, furniture and other combustible materials.

Harden Your Home

• Install ember-resistant vents or approved vent protection where required by local building codes.

• Repair loose, missing or damaged roof materials and seal gaps where embers could enter.

• Use a MERV 13 HVAC filter, or the highest-efficiency filter the system can safely accommodate. Consult the system manufacturer or an HVAC professional if airflow or compatibility is uncertain.

• Consider multi-pane tempered windows and other wildfire-resistant building improvements when renovating.

• Move firewood, lumber, propane cylinders and other combustible materials away from exterior walls in accordance with local regulations.

• Keep the home address visible from the road so emergency personnel can locate the property.

Build Your Go-Bag

Each household member should have a portable go-bag that can be collected quickly. Keep larger equipment, including the Elite 300, as separate vehicle-load items rather than placing them in individual bags.

Include:

• Properly fitting, NIOSH-approved N95 respirators. These can reduce exposure to smoke particles but do not filter hazardous gases, and poor fit or facial hair may reduce protection.

• A portable amount of drinking water and non-perishable food. Store additional emergency water at home and in the vehicle, allowing approximately one gallon per person per day where practical.

• Essential prescription medications and a written medication list. Follow healthcare-provider guidance regarding emergency supplies and temperature-sensitive medicines.

• Copies of identification, insurance records and emergency contacts in a waterproof pouch.

• A battery-powered or hand-crank radio, flashlights and spare batteries.

• Small power banks and charging cables for phones and communication devices.

• Protective clothing, sturdy shoes, gloves and basic first-aid supplies.

• Pet carriers, food, medication and identification records where applicable.

Plan Your Fire Evacuation

• Identify at least two possible evacuation routes, while recognizing that officials may direct residents to a specific route based on current fire conditions.

• Sign up for local emergency alerts and learn the evacuation-zone terminology used by your community.

• Designate an out-of-area contact whom family members can reach if local communications become congested.

• Keep the vehicle fueled and positioned for a prompt departure where safe and permitted.

• Practice loading children, pets, livestock and essential equipment. Evacuating animals or towing a trailer requires additional time and planning.

• Never delay evacuation to retrieve any non-essential equipment.

During a Wildfire: Evacuate or Reduce Smoke Exposure

If Evacuating

• Monitor official alerts closely and leave immediately when instructed. If emergency officials recommend early evacuation for your area, follow that guidance before roads become congested or unsafe.

• Take your go-bags, essential medication, documents, phones and pets. Load larger backup equipment only when it is already accessible and doing so will not delay departure.

• Follow designated evacuation routes and do not take unapproved shortcuts. Roads may be closed because of fire, falling debris, damaged utilities or emergency operations.

• Keep vehicle windows closed and use recirculated air when smoke is present, provided the system is functioning properly.

• Do not enter a road obscured by dense smoke or affected by visible fire unless emergency officials direct you to do so. Turn around when instructed and call 911 if trapped.

• If evacuating with a trailer, RV or livestock, follow the plan practiced in advance and allow additional loading and maneuvering time.

If Remaining Indoors During a Smoke Event

• Remain indoors only when the home is not under evacuation instructions or direct fire threat. A cleaner-air room does not protect occupants from an approaching wildfire.

• Close windows and exterior doors. Use existing weatherstripping where practical and avoid opening doors unnecessarily.

• Set compatible HVAC systems to recirculate rather than bringing in outdoor air. Do not block required combustion-air or ventilation openings.

• Use a portable air cleaner sized for the room. Check its smoke Clean Air Delivery Rate and choose a low- or no-ozone model.

• Operate the air cleaner continuously at the highest tolerable effective speed during poor air quality rather than using an arbitrary on-and-off schedule.

• Avoid activities that increase indoor particles, including smoking, frying food, burning candles and vacuuming without an appropriate HEPA-filtered system.

• Reduce strenuous physical activity and monitor AirNow and local public-health guidance.

After a Wildfire: Returning Safely

Before Re-entering Your Home

• Wait for official clearance from fire or emergency-management authorities. Do not return simply because visible flames have passed.

• Ash and debris from burned structures may contain hazardous chemicals, sharp materials and fine particles. Wear long sleeves, long pants, sturdy boots, gloves and appropriate respiratory protection.

• Inspect the exterior from a safe distance before entering. Look for structural damage, hot spots, smoldering materials, damaged utilities and unstable trees.

• Do not touch or move damaged electrical equipment. Have a qualified electrician inspect systems exposed to fire, heat or water before reconnecting them to utility power.

• Follow local water-utility advisories before drinking, cooking with or otherwise using water after a fire. Boiling does not necessarily remove chemical contamination.

• Do not disturb large quantities of ash or debris without following local cleanup and hazardous-material guidance.

Power and Infrastructure Checks

• Use battery-powered lighting rather than candles inside or near a damaged structure.

• Document damage with photos and video before cleanup when it is safe to do so. Save receipts and records for insurance purposes.

• Be cautious of unlicensed contractors, fraudulent charities and repair scams following a disaster.

• Replace used emergency supplies and review the evacuation plan after the event.

BLUETTI Elite 300 for Wildfire Power Outages

Why Indoor Generator Safety Matters

Fuel-burning generators produce carbon monoxide and must never be operated inside a home, garage, carport or other enclosed or partially enclosed area. Follow current public-health guidance regarding outdoor placement and carbon-monoxide detectors.

The Elite 300 produces no combustion exhaust during operation and is generally quieter than a fuel generator. Never remain in a dangerous area to operate or retrieve backup-power equipment. Evacuation instructions always take priority.

Real-World Runtime for Fire Season Loads

For a basic estimate:

Runtime ≈ usable battery energy ÷ average connected load

Actual runtime will be lower than the theoretical result because of conversion losses, reserve capacity, temperature and changing appliance loads.

Supporting Priority Loads During a Shutoff

The Elite 300 may support selected priority devices during a utility shutoff, but it cannot necessarily run a refrigerator, air cleaner, medication cooler and communication equipment for several days from one charge.

Create a load-priority plan. For example, operate the air cleaner continuously in one occupied room, limit refrigerator door openings and charge communication devices only as needed.

Multi-day support may require additional battery capacity, safe access to grid charging or compatible solar input under suitable conditions.

Medication and Refrigeration Planning

Medication storage requirements vary by product. Follow the manufacturer's instructions and prepare an outage and evacuation plan with a pharmacist or healthcare provider. Use an approved cooler or refrigerator and a temperature monitor where appropriate.

Using the Elite 300 During Evacuation

At approximately 58 lb, the Elite 300 should be treated as separate vehicle equipment rather than an individual go-bag item. Load it only when time, vehicle capacity and conditions allow.

Secure it inside the vehicle so that it cannot shift during travel. Keep it away from direct heat, flames, rain, ash and damaged electrical systems.

At a safe evacuation location, it may support phones, radios, lighting and compatible cooling equipment within its output and capacity limits.

Recharging When Grid Power Is Unavailable

Compatible solar panels may replenish part of the battery during suitable daylight. Recharge time depends on total panel capacity, sunlight, smoke, cloud cover, shade, temperature and system losses.

Wildfire smoke and ash can significantly reduce solar production. Do not rely on a fixed percentage of rated output or use solar as the sole evacuation charging plan.

The Elite 300 accepts up to 1,200W of solar input; panel voltage and current must remain within the Elite 300's input limits. Follow BLUETTI's approved connection guidance before combining panels.

Do not deploy solar panels in an active evacuation area, near fire operations or anywhere they could delay departure.

Wildfire Preparedness Checklist

Conclusion

Wildfire preparedness is not about fear; it is about creating safe options before an emergency. A strong plan combines defensible space, home-hardening measures, reliable alerts, evacuation practice, smoke protection and backup arrangements for essential needs.

Backup power can support communication, filtration, lighting and compatible cooling equipment during a shutoff, but it cannot make an unsafe home suitable for sheltering during an approaching fire.

The BLUETTI Elite 300 may support selected priority devices when loads are calculated and the unit is used safely. It should remain secondary to evacuation orders, fire-safety guidance and household emergency planning.

Prepare early, practice the evacuation plan and follow local emergency instructions when conditions change.

Frequently Asked Questions

How Long Do Wildfire Power Outages Last?

Duration depends on whether the outage results from a utility safety shutoff or physical infrastructure damage. Some outages last hours, while widespread damage may require several days or longer to repair. Follow local utility updates.

Is It Safe to Use a Battery Power Station During a Red Flag Warning?

A battery power station has no fuel-burning engine, but it still produces heat and uses electrical connections. Keep it dry, ventilated and away from flames, excessive heat, ash and damaged equipment. Follow evacuation instructions at all times.

Can the Elite 300 Run an Air Cleaner and Refrigerator Together?

It may support compatible devices if their combined running and startup requirements remain within the output limits. Calculate runtime from the measured average load and allow for conversion losses and battery reserve.

How Can I Recharge During a Multi-Day Smoke Event?

Use an approved AC, solar or vehicle-charging method only when conditions are safe. Smoke, ash, cloud cover and shade may substantially reduce solar output, so do not depend on a fixed daily production estimate.

What Air Cleaner Should I Use for Wildfire Smoke?

Choose a portable air cleaner with a smoke CADR appropriate for the room and select a low- or no-ozone model. For central HVAC systems, use MERV 13 or the highest-efficiency filter the system can safely support.

What Should I Include in a Fire Evacuation Go-Bag?

Include water, food, medication, documents, N95 respirators, flashlights, phone chargers, protective clothing and pet supplies. Keep heavy backup equipment separate and never delay evacuation to retrieve it.
