Wildfire Smoke at School: Questions Families Can Ask About Communication and Indoor Spaces

By the Healthy Learning Environments Guide Team

Wildfire smoke at school raises two practical questions for most families: how will the school communicate as conditions change, and what is being done inside the building while smoke is present? This guide turns established federal guidance into specific, non-directive questions families can ask, without requiring anyone to interpret air-quality data themselves.

Publication boundary: This is an independent educational guide. It does not set school policy, inspect buildings, operate air-quality equipment, or replace a school’s own communication and safety plans during a wildfire smoke event. For the broader framework on asking about school building conditions generally, see the Healthy School Environments foundation guide.

What does federal guidance say about wildfire smoke at school?

The U.S. Environmental Protection Agency identifies fine particulate matter, known as PM2.5, as the main health concern in wildfire smoke, and notes it can affect the heart and lungs, particularly for people with existing conditions such as asthma or heart disease. EPA also points out that smoke events can last for days or even weeks, which is why school buildings need an ongoing plan rather than a single one-time response.

EPA’s 2025 best-practices guidance for schools and commercial buildings during wildfire smoke describes four general areas building managers can address: upgrading HVAC filtration, adjusting the building itself to limit smoke entry, using indoor air sensors to track conditions, and managing day-to-day occupant behavior such as keeping doors and windows closed. A related planning framework recommends that buildings maintain a written, building-specific smoke readiness plan covering these same areas. This publication follows the same sourcing standard described in How We Research.

A separate EPA resource on schools as cleaner-air and cooling centers notes that children are especially vulnerable to wildfire smoke because of their size, physiology, and the amount of time they spend outdoors with less control over their own exposure. It also states that public health agencies are typically the key partners schools work with when deciding whether to open or close facilities as community cleaner-air spaces.

What should families ask about school communication during a smoke event?

These questions focus on process, not on the current air quality number, since only the school and local health authorities have full visibility into current building conditions.

• Where will the school post updates when smoke conditions change during the school day — a website, an app, email, or a phone tree?
• Who at the school decides whether recess, outdoor sports, or other outdoor activities are moved indoors or postponed?
• How will families be told if the school is being used as a community cleaner-air space, and what that means for pickup, drop-off, or extended hours?
• Is there a specific contact for families whose children have asthma or another condition that makes smoke exposure more serious?
• How does the school coordinate with local public health officials when smoke is expected to continue for several days?

The right question often depends on how long smoke is expected to last. If smoke is forecast to clear within a few hours, a single check-in question is usually enough. If local officials say smoke will likely continue for more than a day, it’s worth asking specifically whether the school plans to activate a designated cleaner-air space and how families will be notified if that happens.

What should families ask about indoor spaces during a smoke event?

A family does not need to know how an HVAC system works to ask whether one is being maintained for a smoke event. These questions ask the school to describe its own process.

• Has the building’s HVAC system been checked for smoke events, and does it use higher-efficiency filtration during those periods?
• Are there designated indoor spaces set up to have cleaner air during a multi-day smoke event, and how are students directed to them?
• How are entry points such as propped doors or open windows managed to limit smoke coming inside during the school day?
• If the school is being used as a community cleaner-air or cooling center, is that the same space students use, or a separate area?
• Who monitors indoor conditions during an extended smoke event, and how often?

What’s established by federal guidance, and what depends on your specific school?

Established by federal guidance:

• PM2.5 from wildfire smoke is a genuine health concern indoors as well as outdoors.
• Higher-efficiency HVAC filtration, reduced smoke entry points, and indoor air monitoring are all recommended elements of a building smoke-readiness plan.
• Children are considered a higher-risk group for wildfire smoke exposure.
• Public health agencies typically play a role in decisions about opening school buildings as community cleaner-air spaces.

Not established by this guide, and specific to your school:

• Whether your child’s specific school has adopted a written smoke-readiness plan.
• What filtration level is currently installed in your child’s classroom.
• Whether your district has designated buildings as community cleaner-air or cooling centers.
• How quickly your school’s communication system reaches families once conditions change.

This publication cannot answer the second list for any individual school. Those answers come only from that school’s own staff.

How can families track the answers they get?

Keeping a short written record makes it easier to follow up if an answer is unclear or incomplete.

1. Ask the question and write down the exact wording and the date.
2. Record who answered — the staff member or office, not just “the school.”
3. Summarize what was said in a sentence or two.
4. Note any follow-up needed and set a date to check back.

Ask one question at a time when possible. A short, specific message is easier for school staff to route and answer than a long list combined into one email.

When does wildfire smoke call for immediate action?

This publication does not evaluate current air quality or medical symptoms. If a child is having difficulty breathing, chest pain, or other symptoms during a smoke event, that is a medical emergency — contact local emergency services or a healthcare provider right away rather than waiting for a school response. For real-time outdoor air quality, families can check a public monitoring source such as AirNow.gov, but the questions in this guide focus on what a school is doing about that information, not on interpreting the numbers.
