AGREEMENT STATE REPORT - GAUGES CONTAINING Cs-137 DAMAGED IN FIRE
A fire occurred late on 8/22/2001 at the Crompton Corp. facility at Mapleton, IL potentially involving 17 gauges containing from 50 to 1200 mCi of Cs-137. The fire involved Aluminum Alkyl which is used as a catalyst and burns (at 1800 °F) when exposed to air and can explode when exposed to water. This type of fire is typically allowed to burn itself out, but can be contained with dry chemical agents. After the fire was out, the gauges were surveyed for damage and leakage. Seven of the 17 gauges were damaged, but there was no indication of leakage. The damage was mainly to the lead shielding. The 7 gauges were removed and shielded, then shipped to the manufacturer (Ohmart/Vega) for examination. The manufacturers examination found that none of the sealed sources were damaged.
