CYANAMID COMPANY NEW JERSEY 07470 AREA CODE 701 831-1234 VDc/v/ July 13, 1977 Mr. W. R. Hoopes Organic Chemical Division W. R. Grace and Co. 55 Hayden Avenue Lexington, MA 02173 Dear Ron: Although not a work practice subcommittee member, I recom mend that Tennessee Eastman's proposed additions not be included in the work practice guidelines. The peroxide formation problem is covered adequately under Training 4 along with flammability and polymerization. In case you have not seen the NIOSH request for information on Vinyls in the Federal Register, I attach a copy. I sug gest that we send them the work practices guidelines if this has not already been done. Sincerely, WVA:lh w. V. Andresen Director, Occupational Environmental Services cc: J. T. Seawell MCA 1825 Connecticut Ave., Washington, DC 20009 N.W. '^eb Bell P.P.G. 1 Gateway Center Pittsburgh, PA 15222 received JUL 15 1977 Environmental Affairs
