A paper mill located in a highly industrialized section of Columbia, South Carolina, stores large amounts of liquid chlorine. On May 15, 2000 at 13:00, a reckless forklift operator breaks open a pipe. About 500 gallons of liquid chlorine spray out in a fine mist, and evaporate within about 10 minutes. The chlorine is normally stored at a temperature of -30F. The paper mills single-storied office building is located about 1,000 yards directly downwind of the accident. The building is surrounded by bushes and trees. Since the weather for the past few days has been cool, most people in the building have kept their windows closed. At the time of the spill, the sky was completely overcast, the air temperature was 70F and the wind was from 360 at 10 knots, measured at a height of 10 meters. The relative humidity was 67 percent. The safety officer at the paper mill has recommended chlorines IDLH of 10 ppm as the LOC for this chemical. Use ALOHA to predict the indoor concentration of chlorine within the paper mills office building.
