We’ve teamed up with the Saskatchewan Public Safety Agency (SPSA) and Technical Safety Authority of Saskatchewan (TSASK) to let you know about the crucial need for carbon monoxide (CO) alarms. Why? Because having a working CO alarm in your home could save your life, and the lives of those you love. 

Last year, SaskEnergy responded to over 1,500 CO calls. With a CO alarm, you will have early warning protection against the dangers of the invisible, odourless gas that is often referred to as the "silent killer." 

1. You need them (it’s the law)

“CO alarms are not just a smart choice, but a requirement in Saskatchewan,” says Wayne Rodger, Fire Marshal for the SPSA.

CO alarms are triggered to go off when there is an unusual concentration of CO in the home. In 2022, the Government of Saskatchewan implemented regulations to make CO alarms mandatory in every residence in the province. This includes all residential buildings, houses, apartments, condos, town homes — anywhere that people live, no matter how old or new the building is.

2. They’re available at your local hardware stores

CO alarms are easy to purchase at hardware stores, online, and one even comes included when you book a SaskEnergy Network Home Heating Tune Up. Many models of CO alarms cost around $30 to $40.

3. CO alarms belong on every level of your home

CO alarms should be installed on each level of your home. It is recommended they be placed on any level with fuel burning appliances and outside of sleeping areas. CO alarms should be installed five to 20 feet away from sources of CO such as a furnace, water heater or fireplace. Do not place the unit in dead air spaces where no air circulates, or next to a window or door.

4. They only take a few minutes to install

“Installing a CO alarm is quick, easy and affordable,” says Wayne Rodger, Fire Marshal for the SPSA. “Most models simply plug into an outlet or mount on the wall.”

There are various types of CO alarms. Some have batteries, some are hard-wired, and some can simply plug into a power outlet. Some CO alarms also work as a smoke detector. No matter the type, CO alarms should be installed, maintained and replaced according to the manufacturer’s instructions.

5. They have an expiry date, and need to be replaced

For a CO alarm to be in good working condition, it must not be expired. The expiry date on CO alarms is typically five to seven years. Check your manufacturer's instructions for expiry dates and ensure your CO alarm is up to date.

6. Like fire alarms, CO alarms need to be tested

Just like a fire alarm test, it is recommended to test your CO alarm once a month. It’s important to keep it clear of dust or pet hair. If your CO alarm is battery operated, make sure to replace the batteries as recommended by the manufacturer. 

7. They’re worth a listen

If your CO alarm goes off, stay calm, evacuate your home and call 9-1-1. If you’re experiencing signs and symptoms of CO poisoning, let the operator know and do not re-enter your home until the responders tell you it is safe. If you’re not experiencing symptoms, it’s advised to turn off gas appliances, and open windows and doors to create ventilation. Learn more from TSASK about what to do if your CO alarm goes off.
