New carbon monoxide (CO) alarm requirements under the Ontario Fire Code come into effect on January 1, according to local and provincial fire services.
These changes, introduced by the Ontario Fire Marshal, are designed to strengthen protection against carbon monoxide.
Carbon monoxide is an invisible, odorless, tasteless gas created when fuels, such as propane, gasoline, natural gas, heating oil or wood, do not burn completely in appliances like furnaces, fireplaces, hot water heaters, gas stoves and generators. Exposures to CO can cause headaches, dizziness, nausea, and in severe cases, can be fatal, said an advisory from Ajax Fire and Emergency Services to residents, landlords and building owners.
To prevent exposure to carbon monoxide, make sure fuel burning appliances are inspected annually by a professional. It is also important that venting for the exhaust is kept clear and unobstructed from snow, ice and other debris.
Under the updated Ontario Fire Code:
- Carbon monoxide alarms must be installed on every storey of a dwelling unit.
- In multi-unit residential buildings, CO alarm requirements apply to individual units based on the presence of fuel-burning appliances or attached garages and may also apply to public corridors served by fuel-fired equipment.
- CO alarms may be hardwired, plug-in, or battery operated, as long as they meet recognized safety standards.
Building owners and landlords are responsible for ensuring alarms are installed and maintained; residents and tenants must report any issues with alarms.
“Carbon monoxide can become life-threatening in minutes, and the danger is often impossible to detect without a CO alarm. The new province-wide requirements significantly improve early warning and will help save lives. We encourage all residents to review their home now and ensure CO alarms are installed on every level, adjacent to each sleeping area and are in proper working order.” said Melissa Balson, Public Educator, Ajax Fire and Emergency Services.
AFES Tips
- Test carbon monoxide alarms monthly.
- Plug-in or hardwired carbon monoxide alarms will not operate during a power outage unless there is a battery back-up. Ensure that batteries are replaced in accordance with the manufacturer’s instructions.
- Replace CO alarms at the end of their service life, as listed by the manufacturer.
- Have fuel-burning appliances inspected annually by a qualified technician.
- Keep exhaust vents, chimneys, and outdoor intakes clear of snow, ice and debris.
- Never use generators, barbecues, or portable fuel-burning heaters indoors or in garages.
- Never idle a vehicle inside an attached garage, even with the door open.
