Shell Oil Company Shell Chemical Company Interoffice Memorandum 73. Ctl SEPTEMBER 7, 1982 FROM: SENIOR INDUSTRIAL HYGIENIST DEER PARK MANUFACTURING COMPLEX TO: R. R. ERICKSON, SUPERINTENDENT, HEALTH & SAFETY F. G. REITZ, MANAGER, SAFETY SOUTH H. L. LEE, MANAGER, SAFETY NORTH DEER PARK MANUFACTURING COMPLEX SUBJECT: PROPOSED DPMC EXPOSURE GUIDELINES The DPMC Industrial Hygiene Exposure Guidelines which we previously discussed are provided for your review (Attachment I). The plan is for this to be widely distributed to Safety Inspectors, TSO's, Supervisors, etc. The basis for this document is Attachment II. A comparison between recom mended levels is made. This document is not to be distributed as is Attachment I. Attachment III highlights those chemicals where an OSHA value has not been adopted/applied. This listing is also for our use only. Thanks, P.J. Snyder PJS/mh Attachments cc: M. T. Walsh PJS Chron ECB Satellite LAM 000425 DPMC-16137 ATTACHMENT I DPMC INDUSTRIAL HYGIENE EXPOSURE GUIDELINES SEPTEMBER 1982 Basis Acceptable levels of employee exposure to chemical substances have been established in recent years by various regulatory and scientific groups. This includes the Occupational Safety and Health Administration, (OSHA); the American Conference of Governmental Industrial Hygienists, (ACGIH); and the National Institute for Occupational Safety and Health (NIOSH). Recommenda tions on acceptable levels of employee exposure for individual chemical substances often vary between these groups due to 1) differences in data interpretation, or 2) a review of new health hazard information not previously considered. Where existing acceptable limits of exposure are determined to be inadequate. Shell may establish a Shell Internal Limit; for example, epichlorohydrin. To provide an updated listing of recommended acceptable limits of employee exposure, the attached summary of "DPMC Exposure Guidelines" was prepared. DPMC Exposure Guidelines represent target control levels for employee protec tion. At the minimum, precautionary workpractices, respiratory protection and where indicated protective clothing should be used to reduce exposure to or below the DPMC Exposure Guideline. For many chemical substances, two guide lines have been set 1) a short term @ 15 minutes and 2) an 8 hour TWA. DPMC Exposure Guidelines reflect reasonably current health hazard and toxi cological information and will be updated annually. DPMC Exposure Guidelines are as strict as those established by OSHA and Incorporate Shell Internal Limits where these have been established. Guidelines have been established for those substances with greater exposure potential or in more frequent use. Respiratory Protection For each DPMC Exposure Guideline listed, the minimum type of respiratory protection recommended for use has been identified. Respirators affording a higher level of protection may be used if determined to be appropriate, e.g. a full-face mask may be used to avoid eye irritation instead of a half facepiece; an air supplied respirator may be used instead of a cartridge respirator, etc. Protective Clothing Certain chemical substances have the capacity to cause a toxic effect by being absorbed through the skin. This may occur with or without any local skin effect (reddening, rash, burn, etc). Of those substances which can be absorbed, the capacity or rate in which absorption will occur may vary signi ficantly (slightly, moderately, readily absorbed). Each chemical substance reported to have this capacity has been identified on the listing of DPMC Exposure Guidelines. It is generally recommended that uncontaminated PVC gloves be used for protection against chemical substances which may be absorbed through the skin. LAM 000426 DPMC-16138 A.C.G.I.H. T.W.A. S.T.E.L.
