WARRICK CO., Ind. (WFIE) - We’re learning the liquid that spilled, blocking traffic for several hours on SR 66 was not classified as hazardous waste, according to ORG Chemical Group.
ORG officials said the spilled material was residue from chemical processing with a similar risk as household bleach. The chemical had a high p-h value and had to be washed off to avoid reddening of the skin
ORG said the tanker trailer was over-pressurized and a safety device released six gallons of material.
All lanes of SR 66 between Epworth and Grimm Road are now open.
The spill sent four people to the hospital.
State police say several drivers pulled over after noticing a substance that spilled on their vehicles. They tried to remove it from their windshields. A state trooper responded and then fire crews before discovering the bleach-like substance could be harmful to those who came in contact with it.
State police say a trooper and three other drivers were taken from the scene to St. Vincent for precautionary measures. ISP says at least three vehicles were contaminated by the leak.
A hazmat team with Ohio Township Fire Department decontaminated the three drivers and the trooper before the were taken to the hospital where officials said they received another decontamination wash just to be safe.
Officials say none of the individuals who came into contact with the hazardous material suffered burns or injuries.
“We don’t deal with Hazmat situations very often and we take them very, very seriously because we know a lot of people could be injured very, very quickly. We had to shut down the highway to ensure everyone was safe," said ISP Sgt. Todd Ringle.
The Evansville Fire Dept. says the substance was identified as a non-dangerous byproduct.
Authorities tell us the truck was from Time Dedicated Carriers of Rockport.
ISP says they are still trying to determine what caused the leak. If you drove through the chemical spill Monday morning and have questions or concerns, you can call Chem Group at 812-305-8476.
