Wednesday, November 26 2003 - 11:29 PM WIB
In an event unrelated to the pit wall slippage, on November 22, 2003, regrettably two workers were asphyxiated in an underground tunnel conveying ore from the Grasberg mine to mill facilities. A number of other workers reported symptoms. None were injured seriously and all have been released from the company’s medical facilities. The incident occurred when ore from the Grasberg surface mine containing previously unencountered concentrations of elemental sulphur released fumes in the tunnel. The sulphur was located in a four-by-five meter area, in a low grade section in the outer margins of the Grasberg open pit that normally would have been mined as waste. The event did not involve PT FI’s DOZ underground mine. After completion of assessments by PT-FI and the DEMR inspectors, PT-FI has resumed operations in conjunction with taking appropriate preventive actions designed to ensure similar events do not occur in the future.
