"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 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 September 1, 1972 for Chrysotile Asbestos, as sold by Union Carbide. I have the following cements: ' 1. Under the heading "TRADE KAMES," the term "Calidria" refers to a trademark. I suggest that this 'trademark be set in all capital letters, without quotation narks. ' 2. Under the heading 'HAZARDOUS INGREDIENTS," the words 'Not 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 1' 3. Under the heading "HEALTH HAZARD DATA," "PERMISSIBLE EXPOSURE TO AIRBORNE CONCENTRATION," the present language should be deleted and the following language substituted therefor: .

The heading "EFFECTS OF OVEREXPOSURE" should be modified to read "EFFECTS OF EXPOSURE" and die existing language should be deleted and the following language substituted therefor: . CAUTION: Breathing asbestos may cause serious , bodily harm. . . . 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. #.K ' 4. The disclaimer statenent at the bottom of the Safety Data Sheet should be set in upper case bold type. O.K 5. Under the heading "SPECIAL PROTECTION INFORMATION,1' "OTHER PROTECTIVE EQUIE4ENT," the words "time weighted average or" should be deleted. The sentence will then read as follows: .

The chart which is printed under the heading "RESPIRATORY ~\ PROTECTION" and the accompanying 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. 1 The following sentence should be inserted under .the heading "RESPIRATORY J PROTECTION": / : Proper selection of respirators shall be made according to the guidance of American National _C 0' "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). i JV 6. Under the heading "SPECIAL 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 "When exposure limits may be exceeded..." If you have any questions about the above comments, I will be pleased to discuss this matter further. Also, I can review the new Safety Data Sheet in proof form before it is finally printed, if you wish. CFR:bl cc: J. V. Murray R. F.

INTERVIEWED: Mr. Kanno, Deputy Manager, Tile Production Section Mr. Tajima ' A considerable number of broken bags were found among total 2,250 bags SG-100 delivered under order B-11930. Called upon the factory to check into the problem. Situation: *1 ' Of 2,250 bags, 49 {-1 >Hl.-Tsgs) were found broken, the asbestos powder from such bags flying around and piling up on the container floor. During palletizing operation some more broke and how many more get broken during onward handling was unknown. Problems: . 1. Decreased work efficiency - difficulty in palletization 2. Dusting problem - exposure to asbestos dust (how to dispose of broken bags) Nittobo's request: 1. Nittobo no longer accepts PE bags, so future delivery be made in paper bags. 2. Unbroken bags be replaced with rigid ones for the delivery made today. ' 3. Broken bags be returned to the shipper. Countermeasures: For the request 2 above, replacement is impossible at this moment, and improvement appears difficult for the next order because of the time limit. (The manager Mr. Tsuda said the situation calls for a discount of at least 5 or over, for the drop in the work efficiency much disturbed the production manager.) Tomoe will telex UCC for improvement, and based upon its reply will negot$.tjg 7 UCC 007421 with Nittobo. We will comply with request 3 above. 2- - UCC 007422 A2 07
