REDDING, Calif. -

A large fire had erupted in Redding in a latex product tank at a plant in the area of Highway 273 and Girvan Road in Redding.

All roads are back open as of 3:05 p.m. with the exception of Pit Road, south of Girvan Road.

We can confirm that there has been one hospitalization as a result of burns from the fire.

Officials were advising that smoke from the fire could be hazardous to breathe. The smoke is currently being blown in a westerly direction.

There were voluntary evacuations a half-mile west of Pit Road due to wind blowing west and possible inhalation of fumes.

Redding Fire Dept. said that the plant was doing a maintenance operation on one of the tanks called a "torch operation". Redding Fire informed us that it was a normal procedure but when workers emptied the tank, they did not account for the dried up liquid left behind.

This residue became the flammable material which caused the cylindrical tank to catch fire.

In an effort to put out the fire, the workers first used a fire extinguisher. When this proved ineffective, a second worker grabbed a water hose, causing a chemical reaction.
