New Martinsville, WV (AP) -- Authorities are trying to figure out how six injured men were exposed to battery acid at an oil and gas drilling rig in New Martinsville.
Five of the men remained hospitalized Thursday, a day after being splashed with liquid and aerosol forms of battery acid at Chesapeake Energy's Procko well 20 miles east of New Martinsville.
Wetzel County Hospital Chief Executive Officer George Couch expects two of the men who suffered skin irritations and respiratory problems to remain in the hospital past Thursday.
Wetzel County Emergency Management Director Ed Sapp says the job site has been decontaminated but remains closed as state Department of Environmental Protection investigators search for clues.
Calls to Chesapeake Energy were not immediately returned Thursday.
