MSHA Approves New Dust Monitor
KENTUCKY....
MSHA has approved the use of continuous personal dust monitors. However, their use is not required. The 6.6 pound device a miner would wear into the mine would provide immediate feedback about the dust they're breathing throughout a shift, instead of sampling the air after a shift. MSHA rules requiring a sample averaging exposure over an eight-hour shift have not changed, but the new dust monitors must be able to measure dust levels over a 12-hour period. Officials say MSHA is considering lowering personal dust exposure limits.
