Fire Protection Sys​tems Trailer Training for Fire Departments​​

In August of 2012, we ​rolled out our fire protection systems trailer to train firefighters throughout the state. The trailer has seven full function fire sprinkler systems including three wet systems, two dry systems, pre-action and deluge systems, a mockup of standpipe system and an addressable fire alarm system. This is hands-on interactive training for Minnesota firefighters. We do not charge for this training. The following are necessary at your fire department.

Space Considerations:
  • The trailer is 20 feet long by 12 feet wide by 9 feet tall (fully set-up)​
  • Indoor space is preferred based on weather considerations but can conduct training outdoors if weather is favorable.
Water Supply – access to one of the following:
  • Fire hydrant
  • 1½ - inch truck fill connection​
  • 120-volt power supply

To schedule the training, contact Deputy State Fire Marshal Roy Kingsley via email with dates you have in mind. ​

Sprinkler saves

The Minnesota State Fire Marshal Division is working with the Minnesota Chapter of the National Fire Sprinkler Association to collect information on sprinkler success stories or "sprinkler saves." Many of these incidents have some interesting facts that cannot be completely captured on standard fire reports.

If your fire department responds on a sprinkler activation that might be of interest to others, we encourage you to fill out this form​ and email it back to the email addresses shown on the form.
