The alarm connected to the sprinkler water flow sounded, but only on the second floor, resulting in that floors occupants evacuating the building. The first floor alarm did not sound due to a malfunctioned, and firefighters found occupants still in their rooms on that level.

Burnsville, MN

A sprinkler head protecting the apartment kitchen of an elderly woman quickly stopped a stove top fire. This fast suppression was especially timely because it occurred in one of five apartments in the assisted care living facility that housed memory loss patients. This apartment wing section was separated from the rest of the building a a corridor door, but unknown to building or fire resources; all apartment doors had been removed to better observe the residents. The fire occurred when a portable radio ignited that was placed on a stove burner that was unintentionally turned on. Thick black smoke made its was to the corridor and adjacent apartment units, then the sprinkler activation stopped the fire. A facility staff member suffered smoke inhalation in the attempt of removing residents, but when firefighters entered the area it was reasonable clear. The water flow was shut down limiting the water damage to the apartment carpet and a small section of the corridor floor. The stove and sink area received minor fire damage. Doors have been re-installed and alarm and evacuation procedures evaluated and changed. The effective coverage of the sidewall sprinkler was especially noted.

La Crescent, MN

August 20, 2001

Fire damaged a portion of a company that makes wooden building trusses, but was controlled before it could do major damage. Flames and smoke could be seen in a shed on the business' west side when firefighters arrived, but a sprinkler system and the fire department's new foam truck quickly extinguished the fire.  According to the La Crescent Fire Marshal, "It wasn't very much damage considering what it could have been.  It's basically a lumber yard and it's not uncommon to lose a lot in a situation like that.  Any business that doesn't know whether to put in a sprinkler system should look at this."

Minnetonka, MN

July 6, 1999 

An automatic fire sprinkler system had recently been installed in a multi-tenant office/warehouse building on Opportunity Court in Minnetonka.  Prior to leaving for the weekend, the sprinkler contractor filled the system with water and added 200 lbs. of air pressure (this is common industry practice to check for leaks over an extended period of time).  The main sprinkler control valve was then shut off as the system was not yet connected to a central station monitoring alarm.

On Tuesday, July 6 Minnetonka Fire Inspector Phil Minnell arrived at the building to witness the final acceptance test for this newly installed system.  Once there, he and the sprinkler contractor found two sprinkler heads leaking.  Upon closed examination, and in speaking with the tenant, it was discovered that a fire had occurred over the weekend in a piece of machinery that had ignited an adjacent workbench and plastic garbage can. The fire had been extinguished by the two sprinklers discharging the water that was in the pipes for the acceptance test.  Damage was minimal and even the water damage was insignificant.  Inspector Minnell advised that the damage was so minimal that it was difficult to discover that there had been a fire.

Rochester, MN

December 15, 2001

An early morning fire in a 150 bed nursing facility was extinguished by a single sprinkler head. The fire was restricted to on small corner of a kitchen.  Rochester Fire responded to the incident.

It appears someone set a plastic cup rack on top of a large commercial toaster.  Incoming staff turned on the toaster and left for other duties.  The heated toaster melted the cup rack generating enough smoke and heat to blacken the corner and ceiling overhead, which activated the sprinkler.  There were no witnesses to the event.  The building is operating normally.

  • Police investigating a reported car alarm at Northern Imports determined that the alarm was really coming from Monte's Sports Bar.  Smoke was showing from the roof when the Spring Lake Fire Department arrived at 3:15 am. The first due engine laid 2 hose lines and entered through the back door of the building.  Finding no fire in the kitchen area, they entered the bar.  There they found one activated sprinkler head with water flowing and a smoldering fire behind the bar which had been controlled and nearly extinguished by the single activated head.  Damage was estimated at $50,000.00, but the save was $450,000. Investigators determined that the fire was caused by improper disposal of smoking material which smoldered in a garbage can until it ignited in the middle of the night.

Stillwater, MN

After discovering a fire out of control in their kitchen, residents of a Stillwater townhouse evacuated and called 911 at 2:20 am, March 28, 2002. Stillwater Fire responded and requested mutual aid from Bayport Fire.

Upon arrival of the first engine at 2:28 am, water from just one residential sprinkler head extinguished the fire.  If not for the fire sprinkler system, the fire would have grown and spread rapidly before firefighter's arrival.  Firefighters and residents in all of the attached townhouses would have been endangered more, and damage from fire, smoke and water would have been substantially worse.  Feasibly, all of the attached townhouses could have been damaged or destroyed by fire and smoke.

Because of the sprinkler system, total damage from fire, smoke and water is estimated at $4,000, and residents were not displaced from any dwelling unit in the building, including the one that burned.  The quick response of the sprinkler proved again the value of such systems.
