62-year-old Anthony Towers from Newport is being treated for extensive burns at Maine Medical Center in Portland. 50-year-old Lee Gustin of Cambridge and 36-year-old Clarence Rider from Pittsfield were treated at Sabasticook Hospital in Pittsfield after they complained of respiratory issues, said authorities. Towers was taken to Portland in a Lifeflight helicopter.

Public Safety Spokesmen, Stephen McCausland said, Towers and Rider were working on top of an empty 86 foot tall silo used to store sulfur. A spark set off the explosion as Towers was cleaning out dust and sulfur from the silo with a shovel. Towers' clothing caught fire, and Rider extinguished the fire on his clothing. Both men used a ladder to climb to the ground where Gustin, who was on the ground, assisted them. Investigators are looking into what caused the spark.
