On January 4th we were paged out to a structure fire at a home in Genola. The fire call started at 3:00am and was minus 5 to minus 10 degrees during the call. Santaquin and Goshen responded to give us a hand on this difficult fire. A search was made along with a interior attack, no one was found inside the home. Structural compromise from fire made interior extinguishment dangerous and firefighters were pulled from the house, which then moved to a defencive mode. The cold temperatures made firefighting hazardous with icing of equipment and roads. It took a total of 6.5 hours to get it under control.
