METAL/NONMETAL MINE FATALITY - On March 20, 2001, a 38-year-old foreman with 11 years mining experience was fatally injured at a limestone operation. The victim had placed a lit, hand held propane torch inside an enclosed weigh scale sump to thaw an accumulation of ice. After covering the scale with a tarp to retain the heat, he left to find a second torch. When he returned to the scale, he lit the second torch which subsequently ignited an explosive mixture of gases in the scale sump.

 

• Open flame heating devices should not be left unattended.
• Devices with open flame should not be used in confined spaces where oxygen could become depleted.
• Tests for explosive gases should be conducted prior to using any possible ignition source in a confined space.
