SUPERIOR, Wis. -

It’s Fire Prevention Week, and fire departments are working to educate people on how to stay safe.

This year’s Fire Prevention Week theme is, Don’t Wait, Check the Date! The campaign calls for people to replace smoke alarms every 10 years. To find out how old your smoke alarm is, look at the date of manufacture on the back of the alarm. If it was made more than 10 years ago, it’s time to get a new one.

"Smoke Detectors depending on what kind of features and stuff, can rage from around 12 dollars, to all the way up to about 50 dollars," said Superior Fire Department Battalion Chief Steve Edwards.

The city of Superior Fire department also encourages people to change their CO detectors that are over 5 to 7 years old.
