(NEW YORK) — Spectators at a racetrack in Indiana were sickened by a sulfur dioxide leak on Saturday.
As many as 18 people were admitted to a local hospital, complaining of irritable breathing and burning skin.
The small, dirt track was evacuated and the event was shut down.
Authorities say the chemical was sulfur dioxide and they blame a neighboring facility owned by the Hydrite Chemical Company.
Terre Haute Fire Battalion Chief Joe Swan said, “We believe Hydrite’s got everything shot down and there’s no leaks at this time.”
