In its fire safety message, Greater Sudbury Fire Services advises all residents to develop and practise a home fire escape plan.
“In case a fire starts, everyone must know two ways out of every room, if possible,” said Greater Sudbury Fire Services in a news release. “Get out and stay out. Don't try to save possessions. Go directly to your meeting place outside.”
