Smoke exposure and household questions

Use current advisories for the current event

Health Canada’s wildfire-smoke guidance and the Air Quality Health Index provide public-health information for outdoor smoke conditions. They do not assess residue in a fire-damaged building or authorize entry. Use the current local information rather than an old screenshot of a reading.

For individual symptoms or a personal health concern, contact the appropriate health professional. This site does not diagnose exposure, recommend treatment or determine a personal safe level. Omit medical records and diagnoses from the restoration enquiry.

Clarify the property assessment separately

Ask what building condition or deposited-material question the proposed professional will assess. Professional wildfire assessment guidance and general building-fire restoration have different scope boundaries. A one-line “air test” proposal needs an explanation of its purpose and limits.

A test should identify the decision it informs, the relevant method and how the result will be interpreted. Do not use a household consumer reading or noticeable odour as a general clearance result.

Keep household needs broad in the brief

• State whether occupancy or access is unresolved.
• Describe the property and municipality.
• Ask which qualified expertise is required.
• Discuss personal medical concerns through a suitable health channel.
• Keep authority instructions separate from contractor proposals.

Make a source-control question

Ask whether the concern involves an ongoing outdoor source, affected retained material, equipment or another documented condition. General indoor-air improvements cannot replace addressing the actual source or following specific authority instructions.
