DOVER -- A chemical spill in Tuscarawas County has been cleared and Interstate 77 has been reopened to regular traffic.
Lanes of I-77 in both directions had been closed since mid-morning after the spill was reported at Dover Chemical at 9:20 a.m.
The highway reopened at 2 p.m. and residents were given the all-clear a short time later.
The spill started inside a reactor at the plant. Hazardous materials teams had to use oil to slowly cool the reactor before containing the spill. Water could not be used since it could have started a fire.
The spill created a vapor cloud that was blamed for two injuries. Officials say two drivers passing by the plant were treated for respiratory problems at the hospital.
Two different chemicals were involved in the spill.
One is Dipropylene glycol which is said to have a low toxicity in small doses. It is used as a solvent in industrial applications and is also used in perfumes as well as skin and body products.
The other is Triphenyl phosphite. It is used as a stabilizer in many chemical compounds such as paint or rubber.
The chemicals can cause your skin, eyes, throat, and lungs to burn. Federal guidelines advise that a person who has these symptoms to see a doctor.
No evacuations were ordered but people were advised during the spill to stay indoors with their windows shut and their air conditioners off.
