GREELEY, Colo.—A hockey rink in Greeley was evacuated Saturday due to high levels of carbon monoxide, and more than 30 people who attended a kids’ hockey game there were treated for exposure.
Lt. Curtis Walter of the Union Colony Fire Rescue/Authority said the problem occurred when the rink’s Zamboni and ice edger’s exhaust fumes weren’t properly ventilated.
The maximum carbon monoxide reading in the building was 381 parts per million, he said. The industry standard maximum is 35 ppm.
Arvada Fire Department spokesman Scott Pribble said that after two Arvada teams left the rink, children began exhibiting signs of exposure. The department reported treating 32 people, including players and their family members. Seven of the people were taken elsewhere for treatment.
The Children’s Hospital in Aurora reported treating four hockey players and three spectators; Lutheran Hospital in Wheat Ridge said it treated six hockey players.
Union Colony firefighters also treated a hockey official and coach in Greeley with oxygen for about 30 minutes.
Firefighters ventilated the arena for more than an hour.
