September 22, 1976 "Calidria" Asbestos Answering letter date Subject Material Safety Data Sheet Suggested revisions in the asbestos Material Safety Data Sheet are attached. An annotated copy of Mr. Raeburn's suggestions is also attached for convenient reference. Basically, Mr. Raeburn's recommendations have been followed with occasional minor editorial revisions except as follows: 1. Instead of deleting the respirator use table entirely, it has been updated to fit the current regulations and specific references to products have been removed. Acceptable pro ducts are referenced to NI OSH approval. This will change from time to time but will not affect the validity of this sheet. I think it will be to our advantage to show in a simple way what type of respirators are acceptable for the various concentration ranges. 2. The idea that contaminated protective clothing should not be removed from the plant premises has been added to "OTHER PROTECTIVE EQUIPMENT". 3. The "no smoking" concept is added under VIII SPECIAL PRE CAUTIONS. H. B.

Thurber Metals Division 38th Floor 1 Re: Metals Division - Material Safety Data Sheet - CALIDRIA Asbestos Dear Mr. Thurber: At Bob Fusaro's request, I have reviewed die Material Safety. Data Sheet dated Septerrber 1, 1972 for Chrysotile Asbestos, as sold by Union Carbide. I have the following cements: 1. Under the heading "TRADE FAMES," the term "Calidria" refers to a traderark. I suggest that this 'trademark be set in all capital letters, without quotation ranks. ^ u ^ 2. Under the heading 'HAZARDOUS HvORZDIEOrrS," the words 'Hot Applicable" should be deleted and the following words substituted therefor: Asbestos contains no hazardous ingredients. However, die material itself can be hazardous under certain conditions. (See V below.) . a \> 3. Under the heading 1 HEALTH HAZARD DATA," "PERMISSIBIiE DhCSURE TO AIR30RNE CONCENTRATION," the present language should be deleted and the following language substituted therefor: - *rc r'Jy Effective/July 1, 1976,- the following exposure .a-* limits Under the Occupational Safety and Health ' 'i . . Act of 1970 shall apply: w < tycx The 8-hour time-weighted average airborne concen- tration^of asbestos fibers to which any crployee may be exposed shall not exceed 2 fibers, longer A/-A/*' c* *~*jC than 5 micrometers per cubic centimeter of air, as r* determined by die membrane filter mediod at 400-450 X magnification (4 millimeter objective) phase contrast illumination.

Under the heading "EMERGENCY AND FIRST AID PROCEDURES," the existing language should be deleted and the following language, substituted therefor: No acute toxicity. Use respirator if airborne asbestos, fibers concentration exceeds OSHA limits. ci.K 4. The disclaimer statement at the bottom of the Safety Data Sheet should be set in upper case bold type. O.K 5. Under the heading "SPECIAL PROTECTION FORMATION,'' "OTHER PROTECTIVE EQUIPMENT,'' the words "time weighted average or" should be deleted. Ihe sentence will then read as follows: fin* >2 If*ceiling concentration limit$ s^e exceeded, , clothing providing whole body covering shall be supplied and its use required. c. ' w''7", ^ />t> . The chart which is printed under the heading "RESPIRATORY PROTECTION" and the accoraanying footnotes should be deleted from the \ Material Safety Data Sheet. This information is subject to frequent \ change and the Data Sheet is therefore subject to going out of date. ! JTne following sentence should be inserted under .the heading "RESPIRATORY PROTECTION": Proper selection of respirators shall be made according to the guidance of American National "Standard Practices for Respiratory Protection Z 88.2-1969, and any subsequent regulations on the selection of respirators enacted by the National Institute for Occupational Safety and Health (NIOSH). 6. Under the heading "SPECLAL PRECAUTIONS," the first sentence should be modified to read "If ceiling concentration limits are not exceeded..." and the last sentence should be modified to read "Wnen exposure limits may be exceeded..." If you have any questions about the above comments, I will be pleased to discuss this natter further. Also, I can review the new Safety Data Sheet in proof form before it is finally printed, if you wish. Very truly yours, CFR:bl cc: J. V. Murray R. F. X. Fusaro/File
