eesc MEMORANDUM ASBESTOS GUIDELINES CLARIFICATION October 27, 1972 The recently circulated Group I guideline on the OSHA asbestos standard has resulted in requests for clarification of the statement regarding the manda tory use of Type C respirators during demolition or removal of asbestos insula tion or covering. It is the opinion of the Group I Safety Office that this type work can be performed without respirator protection providing proper and careful monitor ing proves that an exposure hazard does not exist. Two of our plants have determined that the level on small outdoor removal jobs has been below the ,, 5-fiber TLV where care in removal, wetting down, and immediate cleanup were observed. It is emphasized that monitoring must be continued and records maintained to assure that a hazard does not develop. Different conditions such as a large demolition job or an inside job would have to be monitored and judged accordingly.
