Prepare a room for wildfire smoke: a source-based checklist
Use current local information
EPA’s guidance covers preparation for wildfire smoke and indoor air quality. A forecast, a monitor reading and an evacuation order serve different purposes. Start with official local alerts and understand which authority issues instructions for your area. An indoor-air plan does not replace an evacuation instruction or individual advice from a health professional.
A preparation record
| Item | Question before smoke arrives |
|---|---|
| Alerts | Where are official current notices and how will you receive them? |
| Room | Which accessible room can be prepared without creating unsafe heat? |
| Equipment | What does the manufacturer specify for the room and filter? |
| Maintenance | Are replacement filters, power and instructions available? |
| Other sources | Which indoor activities or appliances add pollution? |
| Exit | What is the alternative if staying indoors becomes unsafe? |
Write equipment details rather than assuming any device labelled an air purifier is suitable. Follow current EPA and manufacturer instructions, including limitations of equipment that can produce ozone. A sealed hot room can create another hazard; preparation must consider the actual conditions.
Keep observations distinct from health claims
A fictional household log might record the official alert time, whether equipment was running and an indoor monitor reading with its device name. It should not convert an inexpensive sensor number into a diagnosis or declare the room safe for everyone. Record missing measurements as missing. Changes in outdoor smoke, windows, ventilation and sensor placement can make successive readings hard to compare.
Know when the plan is insufficient
Follow local emergency instructions and obtain appropriate care for health concerns. If power, safe indoor temperature or an accessible location is unavailable, the plan needs an alternative. This worksheet helps organise preparation; it does not assess exposure, guarantee protection or replace current official guidance.
