Carbon Monoxide Hazards
NEVER use a generator in enclosed or partially-enclosed spaces. Generators can produce high levels of CO2 very quickly. When you use a portable generator, remember that you cannot smell or see CO2. Even if you can’t smell exhaust fumes, you may still be exposed to CO2.
If you start to feel sick, dizzy, or weak while using a generator, get to fresh air RIGHT AWAY. DO NOT DELAY. The CO2 from generators can rapidly lead to full incapacitation and death.
If you experience serious symptoms, get medical attention immediately. Inform medical staff that CO2 poisoning is suspected. If you experienced symptoms while indoors, have someone call the fire brigade to determine when it is safe to re-enter the building.
Follow these safety tips to protect against CO poisoning:
NEVER use a generator indoors, including in homes, garages, cellars, garden sheds, and other enclosed or partially-enclosed areas, even with ventilation. Opening doors and windows or using fans will not prevent CO2 build-up in the home.
Follow the instructions that come with your generator. Locate the unit outdoors and away from doors, windows, and vents that could allow CO2 to come indoors.
Install battery-operated CO2 alarms or plug-in CO2 alarms with battery back-up in your home, according to the manufacturers installation instructions. The CO2 alarms should be certified to the requirements of the latest safety standards for CO alarms.
Test your CO2 alarms frequently and replace flat batteries.
