A quick note from the editor:
These three topics are not separate. In a shared building, an alarm is only useful if your neighbour hears it and the stairs are clear.
Detect — smoke & CO alarms
Notify — every unit hears it
Evacuate — stairs actually work
🧭 What should I do next?
Should I care?
Smoke and CO alarms are only useful if they work as a building system. Missed checks can turn one unit's problem into a shared-stairwell emergency.
Who is affected?
Montreal duplexes, triplexes, rental units, and older shared buildings where one alarm, stair, or exit habit affects more than one household.
What's next?
Run one door-to-door alarm audit and document every missing, expired, unclear, or hard-to-hear device location.
