Hotel / Restaurant, Restaurant Madison, WI – Restaurant kitchen fire kept in check by sprinkler system until fire crews arrived April 8, 2019 viking210 An east Madison restaurant sustained significant damage in an early morning fire Friday, officials said. The Madison Fire Department said the fire at Sumo Steakhouse and Sushi Bar on Parkside Drive was kept in check overnight by an automatic fire sprinkler. According to the report, it’s unknown how long the fire had been burning before a passerby called 911 at 2:30 a.m. to report smoke in the area. A crew went to the roof of the restaurant and entered the building through a hatch, officials said. That’s when they discovered light smoke coming from a kitchen vent. Firefighters pulled an attack line and proceeded to the kitchen, where an automatic sprinkler was holding a fire at bay, according to the report. Crews extinguished the remainder of the kitchen fire. Meanwhile, firefighters found fire in the kitchen exhaust system and were able to put it out it with a water can extinguisher. Fire officials said the kitchen suffered significant damage, but without the automatic sprinkler holding the fire in place while nobody was around to report the fire, it is believed the entire building would have been consumed by fire. Public Health Madison-Dane County was notified of the incident. The fire department said the cause of the fire is under investigation.
