*7 2-0.1 INTEROFFICE MEMORANDUM NOVEMBER 13, 1989 FROM: W. B. AUSTIN - SR. INDUSTRIAL HYGIENIST, HEALTH AND SAFETY, DEER PARK MANUFACTURING COMPLEX TO: MSDS BOOK HOLDERS SUBJECT: DPMC EXPOSURE GUIDELINES Attached is a revised copy of the 1987 "DPMC Exposure Guideline". Revisions included changes to permissible exposure limits per the new OSHA AIR CONTAMINANTS RULE, (29 CFR 1910.1000) which became effective September 1, 1989. Most of the changes OSHA made were related to adopting limits from the 1987-88 ACGIH, American Conference of Governmental Industrial Hygienists Threshold Limit Values. The majority of the DPMC Exposure Guidelines represent ACGIH TLV(s), which are published annually, consequently only a few of the exposure limits were affected. The substances for which exposure limits have been changed are indicated by an asterik. If you have any questions concerning revisions to exposure limits, please call me at 7374. Additional copies of "DPMC Exposure Guidelines" can be ordered from Marilyn Dickson, ext. 7335. cc: Health & Safety Staff WBA Chron HSB Satellite CHBT18931701 - 0001.0.0 LAM 013676 DPMC-14966 DPMC EXPOSURE GUIDELINE CHBT8710301 PREPARED BY THE INDUSTRIAL HYGIENE DEPARTMENT NOVEMBER 1989 LAM 013677 DPMC-14967 DPMC INDUSTRIAL HYGIENE EXPOSURE GUIDELINES NOVEMBER 1989 Basis Acceptable levels of employee exposure to chemical substances have been estab lished in recent years by various regulatory and scientific groups. This in cludes 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). Recommendations 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 0 15 minutes and 2) an 8 hour TWA. DPMC Exposure Guidelines reflect reasonably current health hazard and toxico logical 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. CHBT8710301 LAM 013678 DPMC-14968 A.C.G.I.H.
