PIQUA — A chemical spill near downtown Piqua necessitated the closing of a portion of North Main Street on Tuesday.
A box truck carrying hazardous material stopped at the downtown Shell gas station around 9 a.m. when it was reported that something was spilling from the back of the vehicle.
Investigators from the Piqua Fire Department arrived at the scene and contacted the EPA.
It is believed that possibly 20-25 gallons of the chemical P500 (Permacel) Foaming Agent Concentrate spilled onto the concrete at the gas station.
According to the material safety data sheets for the products, P500 is used as a foaming and curing agent for Core-fill 500 resin. It is classified as a corrosive material.
The MSD sheets list the potential human effects as: “This product may be harmful if swallowed. May cause nausea, vomiting, abdominal discomfort and burns.”
The EPA arrived on the scene at 11:20 a.m. and proceeded to neutralize the chemical.
Captain Vince Ashcraft said that that chemical was pretty mild, compared to many.
North Main Street was re-opened to traffic by early afternoon.
