Earlier this week, the Ottawa Paramedic Service responded to an industrial business near Hunt Club and Hawthorne after one person had a fall and felt generally unwell. As paramedics entered the building, their carbon monoxide detector immediately alerted them to the presence of carbon monoxide in the environment. Paramedics promptly ordered the evacuation of the business and went door to door through the complex to instruct occupants to immediately evacuate outside. A total of 9 individuals were evacuated
Four patients were assessed and were found to have carbon monoxide in their blood. One had no symptoms and was released at the scene. Three others had symptoms that included nausea, headaches, dizziness and fatigue, all symptoms of carbon monoxide. They were taken to the hospital in stable condition.
The Ottawa Fire Services were called to the scene and confirmed the presence of carbon monoxide in the air. Carbon monoxide is a lethal gas that is colourless and odourless. It is produced by incomplete combustion of fuels, containing carbon.
Since 2023, all paramedic units are equipped with carbon monoxide detectors that will alert paramedics to the presence of this deadly gas in the environment. In this case, the actions of the paramedics prevented further arm to the occupants of this business complex and ensured the prompt treatment of the affected patients.
