🚨 Incident Snapshot
highCarbon monoxide alarm activation
Residential dwelling, fireplace turned on
Single-family home in suburban setting
⚠️ Primary Risk Signals
CO hazard from fireplace
Fireplace malfunction or improper venting
Confirm fireplace operation and chimney draft on arrival
Multi-unit spread via HVAC
If central heating running, CO may distribute throughout home
Check all occupied rooms for occupant symptoms
Occupant exposure
CO is odorless—occupants may be symptomatic (headache, nausea, dizziness)
Prioritize patient assessment if anyone is symptomatic
✔️ Confirm on Arrival
Fireplace status
Check if fireplace is actively running, inspect chimney/damper for blockage or improper venting
Occupant location and symptoms
Locate all occupants, ask about headache, nausea, dizziness, or malaise
CO detector reading
Note alarm level if detector displays ppm; helps rule in/out CO vs nuisance alarm
Chimney/venting integrity
Look for visible damage, loose connections, or blockage in visible ductwork
🧠 Common Causes
Fireplace damper left closed or partially closed
Chimney blockage from debris or bird nesting
Cracked heat exchanger or disconnected flue pipe
Improper fireplace installation or modification
