This ia exhausted but wa foal that loprovanents oan ba aede base wfalah would rodace tha aaoest of tha exposure. U would suggest that this axhauat ayetae and ancloaure bo atacked to see if It eannot bo adjusted ao that It will ours effectively rnnore the dust froa this operation. There are two operations nere fetch ve wore not able to ssmIo at this tine doe to the feat that these operations wars not in progress. The om la tho slitting saw on tho flatware line and tha other is the un loading of raw natsrial. attached Is a list of reoonsandatlana whleh ve feel would lnprore aondi'-lone at the plant and dacrease the occupational disease exposure free dust. 70 001 0025 J.rtRisua J.
