DENVER (KDVR) — A FedEx delivery truck on its way to Wyoming is stuck on an Interstate 25 ramp in Thornton Monday morning after one of its deliveries started leaking hydrochloric acid, police said.
The I-25 southbound on-ramp at 84th Avenue, as well as 84th Avenue itself, was closed while responders worked to neutralize and clean up the acid, Thornton Fire Department Deputy Chief of Operations Ernie Anderson told FOX31’s Kasia Kerridge. Thornton police said both have since reopened.
Anderson said the FedEx driver noticed the leak at around 2 a.m. Monday as he was on the way from the warehouse to Wyoming.
“The spill at this point seems to be relatively small,” Anderson said. “We don’t have any product running down the road surface or anything, this seems to be contained in the trailer.”
There were five 300-gallon totes of hydrochloric acid, and about 50-75 gallons leaked out.
Anderson said a hazmat team was working on making entry to figure out what the exact problem is, but he expected the process to take several hours.
“They will make entry using hazmat suits; they’ll make entry into the truck, put their eyes on it, identify what the problem is and then relay that information back to the hazmat command side of it to come up with a plan on how to deal with this,” Anderson said. “It will be a process of neutralizing the acid so it becomes more of a non-reactive PH.”
