PADUCAH, Ky. (LEX 18) — Four people are recovering from their injuries after an explosion at a Dippin' Dots production facility in Paducah.
The explosion happened on Friday just before 9 p.m. at a plant on Charter Oak Drive.
Officials said there was a nitrogen leak before the explosion, but it is unknown if that caused the explosion.
Liquid nitrogen is used at the facility to freeze Dippin' Dots ice cream.
The extent of the damage to the building is not known yet, because employees were not allowed to go back inside on Friday night.
That is due to low oxygen levels in the building.
