Seven people were taken to Calgary hospitals Thursday afternoon for exposure to carbon monoxide.
Emergency crews were called to a high rise building located at 50 Brentwood Common NW at approximately 2:40pm for reports of two people feeling ill.
CFD spokeswoman Carol Henke said crews had been using a gas pressure washer inside the building’s parkade at the time.
He said crews found CO levels at the entrance to the parkade measuring 50 ppm, but levels climbed to 1,000 ppm once inside.
Calgary EMS says seven adults were assessed at the scene and transported to hospital in non-life threatening condition.
The fire crews checked each of the residential areas of the building and found that no CO was present, so residents were allowed to stay in their units.
The parkade was closed so no one could enter.
The firefighters then used a large fan to ventilate the area.
