Other Business San Luis Obispo, CA – Suspicious fire at commercial building suppressed by sprinkler system December 13, 2015 viking210 The San Luis Obispo City Fire Department is investigating a series of suspicious fires that have occurred over the past couple weeks. Fire crews were on the scene of two fires Friday night and one fire early Saturday morning. All three fires are suspicious in nature, according to the San Luis Obispo City Fire Department. The first incident took place at approximately 8:20 p.m. on Friday, in a commercial building located at 346 Pacific Street. When freighters arrived on scene, they found three burned garbage containers. The building’s sprinkler system was able to suppress most of the fire. But crews still had to overhaul the fire. The San Luis Obispo City Fire Department says there were cigarettes found in the area, which could have caused the fire. However, there are no leads to whether the incident was accidental or on purpose. The second fire took place at approximately 10:30 p.m. on Friday, behind a commercial building located at 3046 Higuera Street. In this fire, a dumpster and the majority of its contents were burned, according to the San Luis Obispo City Fire Department. Crews were on scene for approximately 15 minutes. At 3:08 a.m. on Saturday, San Luis Obispo City firefighters responded to a third fire. This took place behind Fire Station 1, at the end of Round House Street. When firefighters arrived on scene, they found a large cluster of Eucalyptus trees engulfed in flames. The fire burned about 600 square feet of vegetation and took firefighters approximately 30 minutes to extinguish. Bob Bisson, San Luis Obispo City Fire Department Chief, says this particular fire required the use of fire hydrant water. The San Luis Obispo City Fire Department says they’re concerned about the pattern of fires that have occurred in the city. Last weekend, firefighters also battled fires under suspicious circumstances. Investigators are working to determine their cause.
