Hayden, Staff Engineer Division Engineer's Office Textile Fibers Division Nemours Building Wilmington, Delaware ENGINEERING STANDARD - ASBESTOS DUST EXPOSURE. MEASUREMENT AND CONTROL Reference: Letter September 15, 1972 to Committee Members Requested comments on tentative Safety Engineering Standard S 4 T are listed below with proposal as written and comment indented. 3.^.1 "Insulation to be removed and discarded should be dampened- prior to and during removal whenever possible." Suggest consideration for rewording with reference to "prior to" as a glazed or painted exterior surface will not absorb moisture. Agree with dampening during removal. 5.1 "Respirators and' masks must be kept clean and sterilized prior to reissue". Suggest consideration for expanding to allow the issuance of respiratory equipment to individuals, to be kept and maintained by them as personal protective items. 6.2.2 "Millipore No. MAWP-037-A0 filter, white, nongridded. | O.b micron pore | Millipore Corporation, Bedford, Mass. 01730" Suggest consideration be given to allow use of No. MAWG-037-A0 filters (gridded) by those who may have a current, plentiful supply on hand.
