CO alarm placement
CO alarms provide warning but do not prevent a faulty fuel appliance from releasing gas.
What to observe
Check alarm age, certification and locations against current Ontario requirements and manufacturer instructions.
A field example
An alarm hidden beside a furnace cannot replace required warning near sleeping areas. Check Toronto Fire Services rules and device instructions, and record the alarm's age and test history.
What the written work should say
Use Toronto Fire Services and Health Canada guidance for placement, testing and replacement; maintain the appliance separately.
Where this task stops
A working alarm is no substitute for professional inspection.
