SaskEnergy has issued a cautionary advisory regarding a potential carbon monoxide (CO) threat associated with certain types of air conditioning systems. According to SaskEnergy, some air conditioners that expel indoor air faster than fresh outdoor air can enter may create negative pressure within the home, leading to the possibility of drawing CO back inside from fuel-burning appliances like furnaces, water heaters, and ranges.
Despite the increase in concerns related to this issue, Alana Johnson, SaskEnergy’s director of strategic communications, clarified that the utility is not declaring portable air conditioners as hazardous. Johnson emphasized the importance of understanding the potential risks associated with the operation of portable air conditioners in homes and their impact on indoor air circulation.
Notably, SaskEnergy has observed a rise in calls related to CO concerns linked to the increased availability and usage of portable air conditioning units. The utility highlighted that while using a portable air conditioner may not pose an inherent risk, issues are often observed in residences where such units are used alongside traditional water heaters.
Residents are advised by SaskEnergy to ensure the presence of operational CO alarms in homes, RVs, campers, and cottages. Additionally, opening a window or door slightly while utilizing an air conditioner that expels air outdoors is recommended to promote fresh air circulation.
To mitigate potential risks, SaskEnergy suggests regular inspection of fuel-burning appliances, clearing external exhaust vents of obstructions, and avoiding simultaneous operation of devices that expel indoor air outdoors. Ensuring outdoor units are placed a safe distance from potential CO sources and monitoring signs of inadequate ventilation, such as lingering odors or stuffy air, are also recommended.
Lastly, SaskEnergy underscores the importance of maintaining awareness about CO risks in enclosed spaces and offers additional summertime safety tips, including refraining from starting gasoline-powered equipment indoors and avoiding the indoor use of fuel-burning devices like barbecues and generators. Fire Marshal Ryan Bradley of the Saskatoon Fire Department echoed these sentiments, emphasizing the need for vigilance and the installation of functioning CO alarms as a crucial safety measure.
