Presented herewith are the results of the environmental hygiene survey conducted June 16, 1977 at the Carrollton PVC Pipe Operations. The following will confirm the discussions with Mr, Walters during the course of my survey.
1. Pipe Assembly Table - The exhaust ventilation slots around the table periphery are in need of cleaning to remove solidified resid ual plastic and glue. The table's air exhaust system must be period ically maintained (once/quarter) to control solvent fumes from the glue-weld compositions. Ventilation measurements made at the time of this survey were below minimum acceptable levels.
2. Salt Baths - The salt baths used for pipe band stretching should be adequately guarded to prevent a fall against the hot surfaces and signs indicating the presence,of hot surfaces should be clearly posted. ;
3. PVC Monitoring - The air pump used for PVC sampling has been repalred, calibrated and returned to Mr. Walters. The unit should have the battery back replaced every two years.
PVC air sampling should be conducted on a quarterly basis for at least 18 months to establish a solid data base. Levels consistently below the action level (0.05 ppm) can permit semi-annual monitoring. All samples (certainly the majority) should be taken In the breathing zone of employees.
Sample analysis should continue to be coordinated through Mr. Gaudreau of this department,
4. Noise - Noise measurements made at the time of this survey are con sistent with past survey results. The Grinding Room should continue to be a mandatory ear protection area. All other areas In the plant have acceptable noise exposure levels.

5. Housekeeping - The Blending Department had substantial accunmulatlon of dust on the floor and surfaces. Weekly housekeeping activi ties (at the least)should be established to pick up fugitive PVC . dust. Other areas of the operation were, except for the.flulng tables, acceptable.
If there are any questions, or if I can be of assistance, please call.

: REPORT SUMMARY
Environmental Health Engineering Service
"This survey was made at the request of Mr. Allan Baker, manager, administrative services, to assist in developing information for use in the plant program to control occupational acroosteolysis (AOL).
"Concentrations of vinyl chloride gas to which reactor building workers may be exposed during normal operations including reactor cleaning were measured and are shown in Table X.
"Measurements at a number of locations were made by a direct reading combustible gas indicator (JW Model SSP) . However, the reactor cleaning operation was sampled by means of an activated charcoal tube worn at the collar by a worker during tnis 14-minute operation. The vinyl chloride concentration was subsequently determined
by gas chromatography.
"Ventilation rates on the reactor exhaust ducts were also measured and are shown in Table II.
"In addition, the toxicology of the raw materials was reviewed as was literature
on the process and on AOL.
OLI 4860
This confirmation report concerns only such conditions and practices as were observed and considered at the time of this call. It is not intended to indicate that any hazards are ade quately controlled nor that the conditions meet the requirements of any applicable federal, state, or local law, regulation, or ordinance.
If you hart any comments or questions con cerning this report, write to G. B. Lenthe, Vice-President, Safety <S- Health Services.
Mr. Allan Baker
--2- February 5, 1973
"The following comments and suggestions are based upon the results of this study:
1. The concentration of vinyl chloride gas to which the reactor cleaner was exposed in reactor E 5 was 30 parts per million (ppm), which is 10 percent of the concentration permitted by regulations of the Occupational Safety and Health Administration (OSHA), 25 percent of the current American Conference of Governmental Industrial Hygienists Threshold Limit Value (measurement number 3, Table 1).
2. 'Spot' measurements at other locations shown in Table I do not represent job locations but do indicate unnecessary contributions of vinyl chloride to the work atmosphere.
3. Local exhaust ventilation should be applied to each reactor as it is filled to prevent displaced vinyl chloride gas being discharged from the hatch (measurement number 2, Table I).
4. Scrap barrels should be equipped with close fitting covers to minimize vinyl chloride gas emission from the scrap (measurement number 4, Table I).
5. Ventilation measurements shown in Table II varied from 315 cubic feet of air per minute (cfm) for reactor F 4 to 700 cfm for reactor F 2.
Ventilation capacities of the reactor exhaust ducts should be equalized so that a standard reactor ventilation time prior to entry for cleaning would result in the same exhaust ventilation effectiveness for each reactor.
6. The requirement for use of gloves by reactor cleaners should be continued, to minimize hand contact with scrap being removed.
7. The periodic examination of reactor cleaning personnel should be continued, including 'medical surveillance for symptons of Raynaud's phenomenon and periodic hand X rays...' (Dinman BD, etal: Occupational Aeroosteolysis: I. An Epidemiological Study. Arch Environ Health, 22: 61-73, 1971.)"
