Officials are urging Minnesotans to exercise caution using space heaters, after fire destroyed a trailer home Tuesday morning in Rice Lake Township in Saint Louis County. Authorities say the 59-year-old man told them he had been using several space heaters, the circuit breaker tripped and soon after he smelled smoke. The man was able to safely escape with his dog. The sheriff’s office reminds everyone using space heaters not to overload circuits and don’t leave units unattended, even for a minute.
