⚠️Fire of Note
What makes a fire a "Fire of Note" and why the BC Wildfire Service highlights certain incidents.
🔥 Active Fire Statuses
Out of Control
A fire that isn't responding to suppression and is expected to spread — the most serious status.
🟡Being Held
A fire that isn't growing beyond its current perimeter under current conditions.
🟢Under Control
A fire surrounded by a maintained perimeter that can't cross it. Safe to leave burning to burn out.
⚫Out
A fire that is extinguished or fully burned out and no longer a threat.
🔬 Sensor Readings & Environmental Metrics
PM2.5 & PM10 Smoke
Fine particulate soot concentrations, laser scattering telemetry, and respiratory health thresholds.
🔥CO₂ & Combustion Gas
Non-dispersive infrared (NDIR) telemetry, combustion completeness, and active fire proximity.
📊Air Quality Index (AQI/AQHI)
Piecewise linear piecewise formulas, multi-pollutant scaling, and spatial sensor triangulation.
🌦️Micro-Climate & Wind
Relative humidity 30%/15% drop thresholds, convective flame tilting, and C-Haines instability.
⚡ Fire Causes
Lightning
How dry lightning starts fires in BC, and why it's the leading natural cause.
🧑🤝🧑Human-Caused
The many ways people start fires — campfires, equipment, industry, arson — and how to prevent them.
❓Under Investigation
Why some fires have no confirmed cause and how investigators determine one.
🌲 Fire Weather & Behaviour Values
Fire Weather Index
The FWI chain — how weather becomes a daily fire danger rating used across Canada.
🔥Fire Behaviour
Rate of spread, flame length, and intensity — how scientists predict how a fire moves.
⚠️Risk Levels
How fire risk and danger are scored and what the levels mean for you.
📏Fire Size & Area
How burned area is measured in hectares and what "small" vs. "complex" really means.
🌫️ Air Quality Classification
Good
Air quality is healthy. A normal day to be outside.
🟡Moderate
Acceptable for most; sensitive groups should take it a little easy.
🟠Unhealthy (Sensitive)
Smoke may affect children, the elderly, and those with heart or lung conditions.
🔴Unhealthy
Everyone may begin to have health effects; reduce time outdoors.
🟣Very Unhealthy
Health alert — everyone should limit outdoor exertion and consider masks/indoor air.
🟤Hazardous
Emergency conditions; avoid outdoor activity entirely.
