Two workers say they have been exposed to some sort of vapor cloud while working on a barge along the Kanawha River.
It happened within the hour along the Kanawha River between St. Albans and Institute.
Right now, firefighters tell us they haven't been able to spot anything along the river, but the investigation continues.
Investigators also tell us the two men have been decontaminated and doctors are treating them now.
Firefighters say they believe this is a minor situtation. They've also been in contact with local plants and right now it does not appear anything has leaked from the plants.
