C-8 SAHPLIN6 PROJECT PA6E 3 OF 41
In response to the Summary of 1995 C-8 Blood Testing (Playtis, 1995) results, and subsequent 1996 Industrial Hygiene Follow-up Report (Playtis, 1996), an extensive sampling campaign for C-8 In air and on surfaces (wipe testing) was conducted In Teflon* areas. Areas/jobs that exhibited higher or lower than normal C-8 blood levels were studied In the follow-up report. Sampling priorities for this study were assigned based on the results of the follow-up. The Investigation was conducted by Environmental Lab LSE Jennifer Michols under the supervision of IH Lab Technician Becky Dines.

C-8 IN AIR HONITORIMB
Sample locations, results and any conduslons/pathsforward that were determined are attached {attachment 1). Sampling was conducted using either the Oupont Alpha 2 or P200A pumps with flows set in the range of 200niL/if)in, +/-5iaL/m1n. Sampling media used was conditioned Tenax* sorbent tubes supplied by the TefTon* lab. Analysis was conducted by Teflon* Lab personnel per method WM3627. Six sets of
sampled tubes (206 samples total), along with sample blanks, were
analyzed approximately every two weeks. Set 4, analyzed August 5, 199.7, was found to have a high value
for the blank sample submitted. Upon investigation by Jennifer
Nichols and Chemist Steve Peck, It was found that approximately half
of set 4 (including the blank sample) had been contaminated by an impure reagent. For this report, the amount of contaminant In the blank sample will be deducted from each contaminated sample and shown
In ( ). After the deduction, a number of samples still exhibited
levels worth noting.
It The majority of the air samples were taken In PEP and Horoopolyroer
Control Rooms where a considerable amount of the employee time is spent. Additional monitoring was conducted on roof HVAC units (at the Intake) that supplied these control rooms. Because a possible route for C-8 exposure could be through the HVAC units, an Investigation into these units was conducted and Is attached (attachment 2). The focus was placed on the B-162 units because of their close proximity to the C-8 emissions stack located on B-124 (figure 1). Depending on prevailing wind patterns or weather conditions. was observed that the emission from this stack looped down onto B-162. Weather
it conditions are summarized with the results (attachment 1); for more
detail and observations see notebook S149 R located in Environmental Lab. B-3. The Monomer Control Room was added to the sampling 11st
although was not originally a concern, because it has a roof intake
that Is elosfr to the C-8 emission stack. Additional samples were taken on the C-8 Recovery Operator while
changtpg HVAC filters, in the FP&D wax room, FP&D Oryer Operators
while cleaning the dryers, B-162 smoking area, and the FEP #3 slab drop while In use. Locations were chosen because of information from the industrial hygiene report, or from pathsforward from previous sampling not as extensive as this campaign.

C-8 SURFACE WIPE SAMPLING
Sample locations, results, and eonclusions/pathsforward determined are attached (attachment 3). Sampling was conducted using one to three SKC Smear Tabs per location, the -solvent used on the tabs was reagent quality methanol; reagent used in the analysis. A sampling template was cut to the size of 100cni(2). Sampling techniques were adapted from OSHA's 'Sampling for Surface Contamination Guidelines'. Pink latex rubber gloves topped with a new
pair ofdear latex gloves per each sampled area were used to prevent
cross contamination between locations.
Forty-seven samples -- samples) and 16 from FEP --
31 from Homopolymers (includes roof along with a blank sample were submitted
If for analysis. Analysis was conducted by Teflon* Lab personnel using
method WW3627. A recovery study was set up on Pyrex* dishes and
aluminum lab pans. Results indicate that as concentrations increase,
the percent recovery decreases (figure 3). Many factors (such as
evaporation, size of smear tab, dry time) may contribute to this.

future wipe sampling campaigns are conducted and time
permits, this should be considered in a pathforward*
The locations chosen for the wipe sampling were coordinated with locations chosen for the air samples. Control rooms (excluding FEP's previous oven and extruder control rooms which were in the process of removal), and the areas that surround the control rooms, were sampled. Additional locations included lunch/breakrooas, a lounge, a smoking area, an office area. warehouses and roof locations. The roof locations were also chosen to coordinate with the air samples and so
that as little weather conditions as possible would have affected them
(figure 2), Because of shutdown (non-routine work and extensive equipment replacement) sampling locations were limited to those which
still exhibited surface 'dirtiness'* The type of material sampled was
noted (along with results on attachment 3) and more detail with location sketches can be found in notebook 5149 R located in the Environmental Lab. B-3.
Developing a limit, or concern level, for the dermal dose (amount absorbed through the skin) is not feasible due to the many variables involved. These include; amount of C-8 per a surface area, amount of area the skin is exposed to during a shift, fraction of C-8 that would be absorbed into the skin, and the fraction of C-8 that would be
picked up from the surface. Calculating an estimated dermal dose could give a result that might deviate from a true value by several degrees. Therefore, this study is designed to identify and compare surface areas that have more residua! C-8 than others.

SUMMARYOF PATHFORWARDITEMS
* ADDITIONAL SAMPLING IS NEEDED ON C-8 RECOVERYOPERATOR(08PM) WHILE CHANGING FILTERS. THE FOUR SAMPLES TAKEN WERE ON THE
SAMEOPERATOR. EACHAREANAS OPERATORSWHO CHANGEFILTERS.
TESTING ADDITIONAL PERSONNEL/FILTERCOMBINATIONSRECOMMENDED.
* SOMEAREAS HAD A FEW HIGH RESULTS WHILE MIXED IN WITH LOW RESULTS. ADDITIONAL SAMPLING IN THOSE AREAS IS NEEDED. THEY INCLUDE:
GRANULARPOLYKETTLE CONTROL ROOM (TTP060)
FINE POWDERFINISHING (DRYER)CONTROL ROOM (TTF031)
FEP POLYKETTLE CO^ROL ROOM(TCP2I5)-1ow priority
* IN THE PAST, THE WAXROOM(TTFOZ8) HAS SHOWNHIGH RESULTS. THIS IS CONFIRMED IN THAT EIGHT OF THE NINE SAMPLES IN THIS STUDY WERE OVER THE ACTION LEVEL. ADMINISTRATIVE CONTROLSARE SUGGESTEDON AMOUNTOF TIME SPENT INSIDE THE ROOM. RENEWFREQUENCYFOR ROUTINE
SAMPLING.
* THE SLAB DROP (TCP237) IS A DIFFICULT SAMPLE TO GET DUE TO ITS
LIMITED OPERATION. IT HAD BEEN TARGETED IN THE PAST AS A TROUBLE
AREA AND THESE RESULTS CONFIRM THERE IS APPRECIABLE LEVELS. IT WAS
BROUGHTTO OUR ATTENTION THAT THE BEST TIME TO SAMPLETHIS LOCATION
WOULDBE WHENTHE PRODUCTS100 OR S200 ARE RUNNING AS THEY ARE FINE
POWDEREDAND RUN FAST. CONDITIONS.
ADDITIONAL SAMPLING IS. NEEDEDDURING THESE
* THE B-162 SECOND LEVEL SMOKING AREA (TM0048) SHOWEDCONSISTENT VALUES CLOSE TO THE ACTION LEVEL (0.28 MPB) INDICATING THE
NECESSITY TO FIND AN ALTERNATE SMOKING AREA.
* ONE CONCERN IS THE FINE POWDERFINISHING DRYER OPERATOR(08PI)
U. WHILE CLEANING THE DRYERS. ONE RESULT WAS HIGH (2.4 MPB) WHILE
CLEANING DRYER f3. DRYER #3 CONTAINED A BELT (SHOULDMINIMIZE
EXPOSURE.R) ATHER THAN THE PAPER USED ON DRYER
SINCE SHUTDOWN.
BOTH DRYERS NOWCONTAIN THE BELT. INCIDENT REPORT, FDL970015. FOR THE HIGH RESULT INDICATED MECHANICAL INTEGRITY MAY HAVE BEEN
RESPONSIBLE. THIS WAS THE ONLY SAMPLE TAKEN ON THE f3 DRYER,
THEREFOREFOLLOW-UP SAMPLES ON THIS UNIT SHOULD BE DONE. A HIGH
PRIORITY IS PLACED ON THIS FOLLOW-UP.
* THE ROOF SAMPLES DEMONSTRATEA NEED FOR BETTER CONTROLSON THE C-8 STACK EMISSIONS AND/ORLIMITING THE TIME SPENT (WITHOUTA RESPIRATOR) OM THE ROOF. LOCATIONS CLOSEST TO THE STACK SHOWED LOWER LEVELS THAN THOSE TO THE SOUTH (FIGURE 4) DEMONSTRATINGA LOOPING EFFECT OF THE EMISSION. AS STATED BEFORE, ON SEVERAL OCCASIONS WHEN I WAS ON THE ROOF I WITNESSED THE EMISSION LOOPING EFFECT (DEPENDINGON THE WEATHER). FOLLOW-UP SAMPLING
CAMPAIGN SUGGESTEDAFTER REMEOIATION.

INCLUDED THE JOB 90/50 PACKOlfT BY THE NET FINISH OPERATOR. THIS PRODUCT IS INFREQUENTLPYRODUCEDMAKING SAMPLESDIFFICULT TO 6ET. FUTURESAMPLES FOR C-8 AND NUISANCEBUST ARE NEEDED. * SPECIAL ATTENTION SHOULDBE PAID TO THE AREA WHEREFRESH C-8 IS STORED (OUTSIDEOF THE GRANULARPOLYKETTLECONTROLR06H). IN THE DEC. 18, 1996 MEMORANDUM(FOLLOWUP TO BLOODTESTING) IT WAS CONCLUDEDTHAT THERE WASNO DRIP PAN UNDERTHE TANK'S SP160T AND ONE SHOULD BE PLACED THERE IMMEDIATELY. BURINS AIR SAMPLING THERE HAS A BUCKETCOLLECTIN6 THE DRIP. DURING N1PE SAMPLIN6 THE BUCKET WASNO LONGERTHERE AND WET C-8 WAS DRIPPING AND ACCUMULATINGON THE FLOOR. THIS IS A HIGH TRAFFIC AREA AND IT WOULDBE EASY TO TRACK DRIED C-8 INTO OFFICES, CONTROLBOONS. ETC. NOT ONLY IS THE CATCH BUCKETVERY IMPORTANT, BUT IT IS RECOMMENDEDTO FIX THE SP160T TO REMEDIATETHE DRIP.

C-8 SAMPLIH6 PROJECT PAGE 36 OP 41 WIPE SAMPLING COHCLUSIOHS/PATHSFORMARD
Homopolymers exhibited higher residual C-8 levels than FEP overall. Wipe samples were collected well into shutdown. Once Teflon* is up and running for a while, selecting a few locations sampled in this
project to see how it would compare is recommended.
Setting a routine frequency for wipe sampling is not necessary.
