Wildfire smoke and heat: practical steps for Pacific Northwest households and communities
The Pacific Northwest faces shifting wildfire patterns and periods of intense heat and smoke that affect health, infrastructure, and outdoor life. Preparing homes, protecting vulnerable people, and supporting landscape-scale solutions can reduce risk and keep communities resilient.
Protect indoor air and health
– Monitor air quality: Use national and local air quality maps and public health advisories to decide when to limit outdoor activity.
Many local health departments and environmental agencies offer up-to-date alerts.
– Create clean-air spaces: Run central HVAC with clean filters, and use portable HEPA air purifiers in bedrooms and main living areas. Close windows and doors when outdoor smoke is heavy.
– Masks and vulnerable groups: N95 or equivalent respirators filter fine particles and are recommended for outdoor exposure when smoke is dense. Children, older adults, pregnant people, and those with respiratory or heart conditions are especially at risk; keep them indoors during poor air quality episodes.
– Limit strenuous outdoor exercise during smoke events to reduce inhalation of fine particles.
Make homes ember-resistant and easy to evacuate
– Defensible space: Keep a 5–30 foot zone around structures lean, clean, and green—remove dead vegetation, prune lower branches, and maintain a tidy roof and gutters. Ember intrusion is a common cause of home ignition.
– Ember-proofing: Install ember-resistant vents, seal gaps in eaves and wall intersections, and use fire-resistant siding and roofing where possible.
– Evacuation readiness: Assemble a grab-and-go kit with key documents, medications, water, masks, pet supplies, and basic tools. Keep vehicles fueled and establish multiple evacuation routes with household members.
Landscape and forest management matters
– Support prescribed burns and thinning: Carefully planned low-intensity burns and mechanical thinning reduce hazardous fuels and restore healthier forest structure.
These practices mimic natural processes and lower the risk of extreme wildfires.
– Native, fire-resistant landscaping: Select plants with higher moisture content and low resin or oil.
Maintain irrigation where feasible and avoid placing flammable wooden decks adjacent to dense shrubs.
– Community planning: Encourage fuel breaks around neighborhoods, community chipping days, and coordinated vegetation management with local fire districts and landowners.
Community actions and policy
– Cooling and clean-air centers: Cities and counties can expand cooling shelters and clean-air spaces to support people without reliable home climate control during heat waves and smoke episodes.
– Equity-focused support: Prioritize resources for low-income and rural communities that face barriers to retrofits, air purifiers, and timely information.
– Tribal and scientific collaboration: Work with tribal nations and researchers to integrate traditional burning practices, ecological knowledge, and the best available science into management plans.
Daily habits and long-term resilience
– Adjust outdoor schedules: Move activities to times with better air quality, and postpone outdoor events when smoke is forecast.
– Health plans: Discuss inhaler use and asthma action plans with healthcare providers, and know when to seek medical attention for smoke-related symptoms.
– Stay informed and engaged: Participate in local emergency planning, support funding for forest health and home hardening programs, and join neighborhood preparedness efforts.
Practical, community-centered approaches—combining household preparedness, landscape stewardship, and equitable policy—help the Pacific Northwest weather smoke and heat while protecting health, homes, and the environment. Start with small steps at home and plug into local programs to build wider resilience.
