Other - Retail, Retail Ohotoks, AB, Canada – Fire at mattress store extinguished by sprinkler system August 12, 2018 viking210 A small mattress fire in the local Sleep Country store last night was contained thanks to an indoor sprinkler system. Okotoks Fire Chief, Ken Thevenot, says they were called in a timely fashion thanks to a witness who saw the mattress ignite inside the store. “There was a person on scene that witnessed the fire on a mattress in the Sleep Country business,” he said. He says they were called out around 9 p.m., and when crews arrived on scene the indoor sprinkler system had mostly extinguished the small fire. “When crews arrived, they did see the sprinkler system was activated and the fire was extinguished from those systems. We entered the building, cleared out the smoke and checked the hot spots, and it appeared to be a non-suspicious fire,” said Thevenot. The Okotoks Fire Department is investigating the cause as of today, as there is a possibility it was caused by a short in the store’s track lighting, however, the investigation to determine the cause is indefinite. The Sleep Country store is closed until further notice, and we’ll update the story as it progresses.
