The Thunder Bay Fire Service is starting it's door-to-door smoke alarm checks again. Chief John Hay says it's part of a 5 year plan to go to every home in the city and make sure there are working smoke alarms on every floor. He says they'll go to homes and ask residents if they want a home inspection and to be educated on smoke detectors. Those inspectors will then help residents who don't have any alarms help them be in compliance with the law. Hay says no charges will be laid if inspectors are welcomed into the home
