The Air Quality office now has home carbon monoxide alarms available for the Grand Portage community. These alarms detect dangerous levels of carbon monoxide, a colorless and odorless gas that causes thousands of deaths each year. These are battery powered alarms similar to smoke detectors and should be placed near the bedrooms of the home. These detectors are required in all new construction but many older homes lack them and this could be deadly. I also have equipment to test your appliances and check for carbon monoxide production.
