Craig Fire/Rescue firefighters responded Friday to a report of smoke at Pizza Hut, 1070 W. Victory Way.
Also responding to the call, which came in about 4:45 p.m., were officers with the Craig Police Department and an ambulance crew from The Memorial Hospital in Craig.
Three Pizza Hut employees were transported to TMH, treated and later released, said Jennifer Riley, TMH chief of organizational excellence.
Fire Chief Bill Johnston said Saturday the call stemmed from a complaint by the Pizza Hut employees about a small cooler at the front counter exhibiting blue and orange flames followed by a large puff of smoke.
An investigation of the incident yielded no remnants of flames, Johnston said.
Though it has not been proven, Johnston’s theory is the appliance in question failed, expelled refrigerant, which was inhaled by the employees.
No damage or further injuries were reported.
