April 14, 2022 – Determined Ontarians won’t let a chilly spring evening keep them confined to indoor socializing. On the contrary, a mug of hot cocoa on a moonlit patio could very well set the scene for a romantic first date on a brisk spring night.

As families and friends flock to backyard and restaurant patios to celebrate the arrival of spring, Technical Standards and Safety Authority (TSSA) is teaming up with the Ontario Association of Fire Chiefs (OAFC), Ontario Municipal Fire Prevention Officers Association (OMFPOA), Canadian Propane Association (CPA), and Ontario Restaurant Hotel & Motel Association (ORHMA) to raise awareness of patio heater safety practices. Knowing how to use patio heaters and open-flame appliances properly helps keep outdoor gatherers safe from the dangers of fire and carbon monoxide (CO) poisoning.

Know the risks

The risks of fire and CO poisoning aren’t limited to indoor areas. CO is produced by all devices that burn fuel, like patio heaters, and deadly CO gas can accumulate in any environment with limited air movement.

It is important to ensure that areas where patio heaters are located are well ventilated and verify that smoke and CO alarms located inside nearby shelters and buildings are working properly.

Patio heaters, both portable and fixed, and open-flame units are designed for outdoor use only in open areas away from combustible materials. If used inside a tent or other enclosure or near flammable tablecloths or paper products, outdoor heating devices pose serious safety risks.

Fixed fuel-fired appliances, including fire pits, fireplaces and tabletop units, present additional fire hazards caused by open flames. These units must be installed by a TSSA-certified technician.

Heating device safety rules of thumb

When using patio heaters to make outdoor gatherings more enjoyable, keep these safety rules of top of mind.

  • Ensure outdoor heaters are positioned on a stable surface so they won’t get knocked over.
  • Never leave patio heaters unattended.
  • Pay particular attention when children or intoxicated individuals are in the vicinity.
  • Keep fire extinguishers easily accessible.
  • Never move a portable heater while the flame is lit and make sure the fuel supply is properly shut off and the unit is cool before relocating.

Safety responsibility

It is important to note that this equipment should not simply be pulled out of storage and turned on each year, without being properly inspected and maintained as per the manufacturer’s instructions. Ultimately, owners and operators of outdoor patios and dining areas are responsible for the safe installation, operation, and maintenance of their patio heating units. They must abide by all safety and maintenance instructions outlined in the operating manual for their heating appliances and ensure they understand how to safely operate the heating units and properly handle propane cylinders.

“While fire has associated telltale warning signs, CO is known as The Silent Killer because it is undetectable by smell, sight and taste. In fact, CO is a leading cause of accidental poisonings in Ontario. As such, it is of the utmost importance the patio heaters are situated in well ventilated areas, and CO alarms are installed close by and in good functioning condition.”

“Outdoor heating equipment is a great way to enjoy the fresh air – just make sure it’s air you’re breathing and not carbon monoxide from the fuel-burning appliance. All fuel-burning appliances produce a colourless, odorless, tasteless gas called carbon monoxide, which can be deadly to living creatures. When using heating equipment, make sure you follow all of the manufacturer’s directions and only use them in properly ventilated locations.”
Deputy Chief Rob Grimwood
President, Ontario Association of Fire Chiefs

“Outdoor heating devices are great tools that provide temporary warmth when used according to the manufacturer’s instructions. Improperly used devices can lead to the risk of fire and carbon monoxide poisoning. When using these devices, ensure that they are kept away from combustible materials and used in well-ventilated areas.”
Vince Giovannini
President, Ontario Municipal Fire Prevention Officers Association

“It is exciting to see Ontario’s many restaurant outdoor patios start opening, creating vibrancy across the many communities. It is vital to follow the proper maintenance and operating standards of patio heaters to ensure these operate safely and are placed in the appropriate locations. Safety supports great patio experiences for all to enjoy.”
