Attached Is the National Institute of Occupational Health statement of medical screening to detect liver disease and/ or hepatic tumor which may occur after exposure to vinyl chlorides.
Even though this statement is a recommendation from NIOSH to OSHA, It should become our minimum general medical policy for our employees as well as those employees engaged under contractual agreements.
This program should be put Into effect In vinyl chloride act ivities until such time as additional Information is available and/or until modifications are Indicated by qualified medical authority.
The Corporate Safety Department Is currently preparing a similar document for TDA exposure.
Any changes must be approved by the Corporate Safety Department.
Should you concur with this program for vinyl chloride, ail attend ing physicians for the chemical's group should be notified.

MEDICAL SURVEILLANCE - VINYL CHLORIDES
THE FOLLOWING MEDICAL SURVEILLANCE PROGRAM RECOMMENDED BY THE NA TIONAL INSTITUTE OF OCCUPATIONAL SAFETY AND HEALTH WAS ISSUED ON MARCH 22, 1974. THIS DOCUMENT WILL APPLY TO ALL PERSONS INVOLVED IN VINYL CHLORIDE MONOMER PRODUCTION AND POLYMERIZATION INCLUDING THOSE CLERKS AND MANAGEMENT PERSONNEL INVOLVED INDIRECTLY WITH THESE OPERATIONS. THIS WILL NATURALLY INCLUDE THOSE PERSONS EN GAGED IN RESERACH AND DEVELOPMENT WORK.
THE MEDICAL SURVEILLANCE PROGRAM IS RECOMMENDED TO BE APPLIED BOTH AS A PRE-EMPLOYMENT REQUIREMENT AND AS PART OF PERIODIC HEALTH FOL LOW UPS.
1, AT TIME OF INITIAL EMPLOYMENT OR UPON INSTITUTION OF SCREEN ING, A PHYSICAL EXAMINATION SHALL BE PFRFORMED WITH SPECIFIC ATTENTION TO DETECTING .ENLARGEMENT OF LIVER OR SPLEEN BY AB DOMINAL PALPATION.
2. AT TIME OF INITIAL EMPLOYMENT OR UPON INSTITUTION OF SCREENING AND ANNUALLY THEREAFTER, A MEDICAL HISTORY CHECK-LIST SHALL BE COMPLETED BY THE EMPLOYEE. THIS LIST SHALL INCLUDE QUESTIONS CONCERNING;
A. ALCOHOL INTAKE B. PAST HISTORY OF HEPATITIS C. PAST EXPOSURE TO HEPATOTOXIC AGENTS, INCLUDING DRUGS AND
CHEMICALS D. PAST HISTORY OF BLOOD TRANSFUSIONS E. PAST HISTORY OF HOSPITALIZATIONS
COMPLETED MEDICAL CHECK-LISTS SHALL BE REVIEWED BY A PHYSICIAN AND SHOULD BE ACTED UPON AS MEDICALLY INDICATED FOR EACH EMPLOYEE.

3. AT TIME OF INITIAL EMPLOYMENT OR UPON INSTITUTION OF SCREENING, A SERUM SPECIMEN SHALL BE OBTAINED FOR SCREENING WITH RESPECT TO THE FOLLOWING FIVE (5) BIO-CHEMICAL DETERMINATIONS OF LIVER FUNCTION:
A. TOTAL BILIRUBIN B. ALKALINE PHOSPHATASE C. SERUM GLUTAMIC OXALACETIC TRANSAMINASE (SGOT) D. SERUM GLUTAMIC PYRUVIC TRANSAMINASE <SGPT> E. GAMMA GLUTAMYL TRANSPEPTIDASE CGGTP)
ADDITIONAL TESTS THAT MAY OPTIONALLY BE CONSIDERED FOR USE IN SCREENING INCLUDE LACTIC DEHYDROGENASE (LDH>, SERUM PRO TEIN DETERMINATIONS, SERUM PROTEIN ELECTROPHORESIS, AND PLATELET COUNT. LABORATORY ANALYSES SHALL BE PERFORMED IN LABORATORIES ACCREDITED BY THE COLLEGE OF AMERICAN PATHOLO GISTS OR LICENSED IN ACCORDANCE WITH THE PROVISIONS OF THE CLINICAL LABORATORIES IMPROVEMENT ACT OF 1967.
4. IF RESULTS OF LABORATORY SCREENING ARE NORMAL, SCREENING SHALL BE REPEATED ON AN ANNUAL BASIS. (F THE PERSON BEING SCREENED HAS BEEN EMPLOYED DIRECTLY IN VINYL CHLORIDE MONOMER PRODUCTION OR POLYMERIZATION FOR TEN (10) YEARS OR LONGER, SCREENING SHALL BE REPEATED EVERY SIX (6) MONTHS.
5. IF ONE OR MORE LIVER FUNCTION TESTS ARE ABNORMAL, SERUM TESTING SHALL BE REPEATED AS SOON AS POSSIBLE, PREFERABLY WITHIN TWO (2) TO FOUR (4) WEEKS. IF NO ABNORMALITIES ARE PRESENT UPON RESCREEN ING, TESTING SHOULD BE REPEATED IN THREE (3) MONTHS.

6. IF ABNORMALITIES PERSIST ON RESCREEN ING# THE EMPLOYEE SHALL BE REMOVED FROM CONTACT WITH VINYL CHLORIDE MONOMER OPERATIONS AND AN INDIVIDUALIZED MEDICAL WORKUP SHALL BE INSTITUTED. SUG GESTED AS INITIAL STEPS IN MEDICAL WORKUP ARE A OOMPLETE PHYSICAL EXAMINATION AND VARIOUS SPECIAL PROCEDURES SUCH AS HEPATITIS "B" ANTIGEN DETERMINATION AND LIVER SCREENING.
IF LIVER FUNCTION ABNORMALITIES ARE DETERMINED TO BE UNRELATED TO LIVER DISEASE CE.G., ELEVATED ALKALINE PHOSPHATAES IN A YOUNG, PHYSICALLY ACTIVE MAN OR ELEVATED BILIRUBIN IN GILBERT'S SYNDROME) OR TO BE TRANSIENT (E.G., DUE TO RECENT HEPATITIS OR RECENT ALCOHOL INTAKE), THE EMPLOYEE MAY BE PERMITTED TO RETURN TO VINYL CHLORIDE RELATED EMPLOYMENT, SUBJECT TO INDIVIDUAL MEDICAL EVALUATION.
7. IN VIEW OF THE PRELIMINARY RESULTS OF ANIMAL TOXICOLOGY STUDIES, IT IS RECOMMENDED THAT NO WOMAN WHO IS PREGNANT OR EXPECTS TO BE COME PREGNANT SHOULD BE EMPLOYED IN VINYL CHLORIDE MONOMER OPERA TIONS.
NOTE I - AS VINYL CHLORIDE IS STILL UNDER INVESTIGATION BY NIOSH, IT IS ANTI CIPATED THAT THERE MAY BE CHANGES IN THE MEDICAL SURVEILLANCE PROGRAM. THIS DOCUMENT WILL BE UP GRADED AS THE NEED ARISES.
NOTE 2 - THIS DOCUMENT STATES THE MINIMUM REQUIREMENTS. SHOULD ANY ATTENDING ' MEDICAL AUTHORITY DEEM THAT ADDITIONAL WORK MAY BE NECESSARY, THESE RECOMMENDATIONS WILL FORM THE BASE LINE EVALUATION.
NOTE 3 - AS THESE RECOMMENDATIONS COULD APPLY TO ANY KNOWN OR SUSPECTED LIVER DISEASE OR HEPATIC TUMOR PRODUCING AGENT, THEY SHOULD NOT BE RESTRICTED TO VINYL CHLORIDES.
NOTE 4 - ALL CHANGES TO THE RECOMMENDATIONS CONTAINED IN THIS DOCUMENT SHALL BE CLEARED THROUGH THE CORPORATE SAFETY DEPARTMENT,

1. Background. Vinyl chloride (ctaloroethene), Chemical Abstracts Service Registry No. 75015, is a synthetic chantcal made by crychlorination, of ethylene or bp hydrocfalorlpatfon of acetylene, it is the parent compound of a series of thermoplastic resin polymers and co polymers which are widely used for con
tainers, wrapping tissues, electrical In sulation, pipe, conduit and a rartety of other products. Vinyl chloride has been made commercially In this country since 1939 and present production it in excess
of seven billion pounds per year. vinyl chloride (VC) Is a gas at am
bient temperature and pressure and la a chlorinated hydrocarbon which has mod erate liver toxicity. The present standard sets a ceiling value of 509 parts per million (ppm) (29 CTO 1810.93).
On January 23,1974, the Occupational Safety and Health Administration was
informed by the National Institute for Occupational Safety and Health (NIOSH) that the B. P. Ooodrich Chem ical Company reported that deaths of several of Its employees from a rare form
The employees of the B. F. Goodrich Chemical Company who died from angloearcoma of the liver had an average exposure of approximately 19 years to vinyl chloride, at unknown concentra tions, and variable exposures to other
volatile chemicals. (TR 93). Some em ployee* of Union Carbide Company and Goodyear Company are also reported in a prirt-hfari"g comment from NIOSH
dated March 11. 1074. to have had ex posure to vinyl rfitnrui* and to have died from angiosarcoma of the liver. Finally,
autopsies of four deceased employees re vealed that liver angiosarcoma tumors were histologically tndistinguishable from the angiosarcoma tumors observed is n ofmnor Idaltoni's experimental ani mals. It is concluded therefore, that vinyl chloride Is carcinogenic tor hu mans.
We therefore conclude that the present standard for VC should be lowered from a ceiling of 500 ppm to a ceiling of 50 ppm for the following reasons:
