Sunday marks the start of Fire Prevention Week in Minnesota, and the Duluth Fire Department has some tips on what people should know to help prevent disaster.

Duluth fire officials said if a smoke detector goes off for three or more beeps at a time, that means there is smoke or a fire in the house.

If that's the case, you should evacuate and call 911.

One beep from the smoke alarm every 30 to 60 seconds means to change the battery.

The entire smoke detector needs to be replaced about once every 10 years.

Assistant Chief Brent Consie with Duluth Fire Department said taking these precautions now can help prevent disasters in the future.

"This year with Fire Prevention Week coming up, it's mostly so we can get the message out to kids and students about fire safety in the home and just how to react if smoke detectors go off," Consie said.

Smoke detectors should also accommodate family members with sensory needs.

During the month of October, life safety staff from the fire department will be visiting Duluth schools and going over safety and fire prevention tips.

Minnesota Governor Tim Walz ordered all flags to be flown at half-staff Sunday to honor firefighters and first responders.
