Industrialhygiene Survey Centerville Plant, April 29, 1976
BUSINESS CONFIDENTIAL --------------------------------
Dear Mr. Bleliskl:
An Industrial hygiene survey was conducted at Centerville on
April 29, 1976. Air samples were collected and analyzed for vinyl
chloride monomer or total dust content, l&e results of these samples
are shown In the attached tables of data.
lfce lateness of this report Is due partially to the time required
to obtain analytical results and partially to an exceptionally heavy
travel schedule the past two weeks. I regret the delay.
The air sample collected on the person of the PVC Blender Operator
did contain enough vinyl chloride monomer that It could be detected
by the existing analytical technique. The 0.08 ppm, representing the
exposure of this employee over five hours and three minutes of his work
shift, representsthe first positive result this office has ever obtained
on any employee at Centerville. This probably relates to the fact that
this la the longest term single air sample collected to date on any of
these employees. However, this result Is still well below even the
existing action level for VCM in workroom air.

The air sample*, collected this time os the person of the Powdering-
Machine Operator, gave a time-weighted average concentration of 17.7
milligrams of potato starch per cubic meter of workroom air over the
k hours and 50 minutes duration of these samples. This result Is above
even the present standard for a nuisance-type dust. This 06H& standard
is considered as too high for any dust exposure both by the American
Conference of Governmental Industrial Hygienists and by this office.
The appearance of this Powdering Roam reflected this unusually high
Concentration of airborne starch. There was much settled dust visible
on all horizontal surfaces. This operation must be tightened to better
contain the starch powder.
While no air samples were collected this time in the FVC Extrusion
Room, it was observed that the Ho. U Extrusion Machine was masking
rather heavily. The existing exhaust ventilation system was unable to
handle this anoke, and it did accwulate in this area.
Experience would indicate that such smoke probably consisted mainly
of water vapor and vaporized plasticizer material, and that it would
not be highly toxic. However, this is not a normal operating conditi n,
and such equipment must be repaired as quickly as possible.
The solvent odor was very strong in the Frin|ii% Press Roam. This
would suggest that the exhaust ventilation system might need cleaning
to restore it to peak efficiency*
I greatly appreciate the many courtesies extended to me during my
visit. If I can be of further assistance, please let me know.
Very truly yours,
EGB/eg Enc.

Dear Mr. Blackwell:
An industrial hygiene survey was nade at Ottawa on February 25-26,
1976. file lateness in this report is due to an extended delay in getting
analytical results from the laboratory. The results for vinyl chloride
and dust are shown on the attached tables.
With regards to vinyl chloride it is recosnended that the Banbury
operator on line 5 be rechecked since the level found was essentially
at the Unit. In the silo area leakage was noted at the covers, and
doors were open so that exhaust ventilation patterns were not noraal.
The other locations checked were well below the Unit for vAnyl chloride.
Ousts in the vinyl production areas were quite noticeable and house
keeping could be considerably improved. The Units for total dust are
based on the cristoballte content of the filler materials such as Silver
Frost. It Is expected that additional sampling will be performed go
ascertain better exposure evaluation to lead and tin duat in air since we
were not able to use the data obtained on this survey.
In other plant areas, there were sene noise problems noted and current

practices to reduce overall noise levels should be continued since it is probable that 85 dBA will be the limit before the year is out*
la extruder areas, if reduced ventilation rates are considered, it should be pointed out that ozone generated tram, treating could be a problem. Also, exhaust gases frem a process area should not be exhausted to another work area.
the possible use of catalytic converters on fork trucks to reduce carbon monoxide in building areas was also discussed.
The probable restriction of use of various chrome containing compounds as colorants for various products was also discussed. If adequate control were possible, these materials continued to be need.
Thanking your., for thecourtesies extended, we remain Very truly yours,

^ Operating problens were present during this stapling period and very little Material was processed.
The Unit for total dusts in this area would be 1.7 ag/M^ based on erlstobalite content.
The Halt for tin is 0.10 ag/M^ and for lead 0.15 ag/M^. All of these staples were analysed for lead and tin, but due to apparent laboratory problens, they are not being reported.
