DAYTON — UPDATE @ 6:40 p.m
A liquid nitrogen leak that led Hazmat crews to respond to a Dayton business has been resolved and the roads are back open.
Dayton fire crews were called around 5 p.m. to a report of a white vapor cloud coming from the back of a semi at Airgas Priority Nitrogen, 3440 Needmore Road.
The liquid nitrogen, which turned into a vapor as it escaped its insulated tank, posed no risk of explosion or fire, Dayton District Fire Chief David Wright said.
“The issue with the liquid nitrogen is that it displaces oxygen so if we end up with a large pool of that we could have a very oxygen-deficient environment, could be very very hazardous to people’s health,” he said.
Nitrogen escapes through a release valve in the tank naturally, but Wright said it appeared to be “a substantial leak.” The tank was filled this afternoon, but it’s not clear how much leaked from it.
Nitrogen is naturally found in the air, and crews were monitoring the air quality, Wright said.
A Hazmat crew was called tonight to a liquid nitrogen leak at Airgas Priority Nitrogen.
Dayton fire crews responded around 5:10 p.m. to the industrial incident at 3440 Needmore Road to a report that a semi was leaking gas on the property.
According to reports, the semi was leaking liquid nitrogen from a rear valve.
A portion of Needmore Road is blocked to traffic in the area of the business, roads nearby also are closed.
