MOOSE, Wyo. \u2013 Multiple Fire, EMS, and law enforcement units from both Jackson Hole and Grand Teton National Park (GTNP) responded Wednesday to a report of a structure fire at Dornan's in Moose.\r\n\r\nThe initial 911 call at 5:52 pm reported a fire at 12170 Dornan Road in the Chuckwagon kitchen and possibly the attic. The fire occurred during a large dinner event at the location, reported to involve several hundred people. The location is a private commercial inholding within Grand Teton NP.\r\n\r\nGTNP Engine 1 from Moose arrived at 6:04 pm to find a single-story structure with smoke coming from doors and eves. Bystanders reported that all occupants had been evacuated and that the fire had started in a commercial kitchen. Prior to the arrival of emergency units, staff had applied multiple fire extinguishers to the fire and had been successful in suppressing the majority of the fire.\r\n\r\nEngine 1 and JH Fire\/EMS Engine 11 from Jackson made entry into the structure and worked to ensure that fire had not established itself in the attic and roof system. Once fire suppression efforts were accomplished, efforts were taken to minimize the impacts on the event.\r\n\r\nNo injuries to the public or emergency responders were sustained. The structure itself sustained fire damage to kitchen equipment with accompanying smoke damage in some portions of the building.\r\n\r\nJackson Hole Fire\/EMS Fire Marshal Kathy Clay investigated the fire\u2019s area of origin and is expected to have a final report available soon.\r\n\r\nThe event is a good reminder of the value of fire extinguishers. Make sure you have fire extinguishers in your home and business. Check them regularly to make sure they are functional. And, finally, make sure you know how to use them.\r\n\r\n\r\n\r\nFire extinguishers can be helpful for a small fire. As you prepare to utilize a fire extinguisher, consider:\r\n\r\n \tHave I alerted others in the building of the fire?\r\n \tHas someone called 911?\r\n \tIs the fire small and contained in a single object (like a box or a trashcan)?\r\n \tWill I be safe from the fire\u2019s toxic smoke?\r\n \tWill I have a clear escape route?\r\n\r\nIf you\u2019re unsure about whether or not it\u2019s safe to deploy a fire extinguisher, alert others, leave the building, and call 911.\r\n\r\nWhen operating a fire extinguisher, remember the acronym PASS:\r\n\r\n \tPull the pin. Hold the extinguisher with the nozzle pointing away from you and release the locking mechanism.\r\n \tAim low at the base of the fire.\r\n \tSqueeze the lever.\r\n \tSweep the nozzle from side-to-side.
