Fire crews were dispatched Friday afternoon to a chemical spill at a Salt Lake City plant.

A hazardous materials team spent several hours at the Thatcher Chemical plant, 1900 W. Fortune Road (1800 West), after a chemical spill sent an orange-yellow cloud from the facility's scrubber system, according to the Salt Lake City Fire Department.

Crews responded at about 2 p.m. and found a spill of about 550 gallons of a highly acidic mixture of calcium nitrate, calcium nitrite and an unidentified third product. Company workers used caustic soda to neutralize the spill prior to dumping it into a holding tank. Firefighters reported the spill was contained within the plant's building but some gases did escape from the scrubbers. No injuries were reported.

According to its Web site, Thatcher Chemical manufactures industrial chemicals and photo chemicals.
