Sixteen children have been hospitalized after suspected carbon monoxide poisoning at an ice-skating rink in Adelaide. Firefighters were called to the scene and found high levels of chemicals in the air, including carbon monoxide and hydrogen cyanide. Two pieces of machinery, a dehumidifier and an ice resurfacer, are believed to have caused the hazardous situation and have been isolated for testing. The children’s conditions are significant but not life-threatening. SA Health has been contacted for comment.
