Explosion fears remain as N. Carolina fertilizer plant burns

An uncontrolled fire at a fertilizer plant has continued to burn in North Carolina. Fire officials in the city of Winston-Salem said the potential for an explosion had not gone down early Wednesday. Thousands of evacuated residents are still barred from going home. Bobby Wade is a division chief for the city's fire department. He said the burning down of the fire  will be a slow process. He could not say when people can return to their homes. The fire is at the Winston Weaver Company fertilizer plant on the north side of the city of about 250,000 people. The blaze began Monday night. An estimated 500 tons of combustible ammonium nitrate were housed at the plant.
