As you will notice, three of the lathes were found to be over the maximum average anno spheric concentration of contaminants to which workers maybe exposed for on eight-hour working lay without injury tc health. It is obvious that a safety hazard does exist in these areas. Presently, action is being token to correct the deficiencies of the dust collecting system by installing more adequate means of collection at these lathes, however, in is thought that sore remedial action should be taken in the interim until such time as she situation, has been corrected. As a temporary expedient, to eliminate the health hazard, it is recommended that the operators working on these specific pieces of equipment be requested to wear respirators until such tine as adequate collection facilities can be installed. It is also recommended that the operators be informed of the situation so that they will have a better understanding for the need of a respirator in an attempt to educate the operators and gain their acceptance as to their use. cc: J. .j.
