INTRODUCTION The survey was conducted at the request of Betsy Leff,
C.S.P., American Home Assurance Co.f San Francisco, CA. On September 19, 1983, a walk-through survey of J-M
Manufacturing Co., Inc., Denison facility, was conducted to acquaint the survey team with production activity of the Transite (asbestos-cement/A/C) pipe. Polyvinyl Chloride (PVC) Shop, Injection Mold, Permastran and Cool Core, and Permaloc-Lining & Temp-Tite areas. Exposure potentials to airborne asbestos fiber, vinylchloride monomer (VCM) , respirable silica dust, solvent vapors, carbon monoxide (CO), total particulates and noise were investigated and a sampling strategy developed.
Assistance was provided by Mr. Jim T. Armstrong of J-M Manufacturing Co., Inc., so that previously sampled locations bearing J-M sample designations were included in the survey along with additional locations or job descriptions as prescribed by Health Science Associates, in accordance with good Industrial Hygiene practice.
Actual monitoring occurred during the day shift, Monday through Friday, beginning September 20, 1983 and ending October 7, 1933, inclusive.
At the time of the survey, many of the infrequently used lathes in the Transite area were not in operation. However, additional sampling equipment was kept in reserve and was used to monitor the operation of such equipment

when put into service; Thus, in some instances, sampling periods of less than 8-hours represent the entire duration of operation and, hence, all the exposure potentials for the given operation.
Transite area personnel were sampled for airborne asbestos fiber and respirable silica (SiC^) dust. PVC assembly moulders, located within the transite production area, were also monitored for exposure to solvent vapors consisting of tetrahydrofuran (THF) and ethyl acetate (E/A) .
Vinyl chloride monomer (VCM) monitoring was conducted wherever the possibility of work in proximity to heated PVC, by either hot extrusion, molding, or belling operations, were noted. Accordingly, PVC, permaloc, permastran, and injection molding area personnel were monitored.
Solvent vapor sampling for methyl ethyl ketone (MEK), acetone (AC) , and methylene chloride (MeC^) in the permastran area was done.
Personal noise dosimetry measurements were obtained for all areas of the facility, including maintenance personnel.
Total particulate sampling of mezzanine level batching operations in the PVC and injection molding areas was also accomplished during normal full shift activity.
Long term (duration) carbon monoxide (CO) monitoring of transite area power truck drivers was done during normal work activity.

OPERATIONS WEEK_ONE_
Begining on Tuesday, September 20, 1983, personnel in forming and finishing classifications in the transite area were sampled for airborne asbestos fiber exposure during normal work activity.
Some equipment did not operate, however. Therefore, samples could not be obtained for the ten foot pipe machine (10' P/M) crew, and the tracer and sample lathe operators. Noise dosimetry was accomplished for the operators as. well. Notable exposures and the associated products are explained in the results section. WEEK_TW0_
Crew members sampled during week one were resampled for total respirable particulates (respirable silica dust) during full shift activity.
Solvent vapor monitoring for PVC assembly moulders using PVC 1969 Green Glue (containing tetrahydrofuran (THF)) and ethyl acetate (E/A) as the solvent for cementing of PVC joints and elbows occured at this time.
This location was situated within the transite production area.
Permaloc personnel monitoring for vinyl chloride mono mer (VCM) and noise at all operating lines was conducted. Area VCM was also conducted to establish what levels, if any, were emanating from the source, i.e., directly over the hot

extrusion end of extrusion machine no. 2.
In the same manner, PVC shop personnel were monitored
and area sampling was conducted. Operators were assigned
to all machines. This was an assignment change instituted
recently. Thus, in some .cases, the J-M sample numbers do
not apply.
.
Sampling of week two occurred from September 26th
to the 30th, 1983.
WEEK_THREE_
During the final week of sampling, all remaining
areas, permastran and cool core, injection molding, permaloc-
lining and temp-tite operations were sampled for VCM and
noise. Batching operations at PVC and injection mold mezzan
ine levels were sampled for total particulates as well.
Personal noise dosimetry was conducted for maintenance
employees at this time. Sampling began October 3, 1983, and concluded on October
7, 1983.
METHODS
Personal and area air samples were collected by the use
of portable battery operated sampling pumps connected by
tubing to the appropriate collecting media. Air flow rates
were established by means of a bubble buret method calibrated
field rotameter immediately before, during, and immediately
after the sampling period.
D 002353

Employee breathing zone sampling was achieved by
mounting the collection media on the employee's collar and
the sampling pumps at waist level.
All samples were analyzed in HSA's AIHA accredited
laboratory (except for direct reading DrSger tubes used for
CO monitoring).

Noise dosimtery was accomplished with the use of GenRad
model 1954 audiodosimeters. These were set on the operating
range of 80-130 dBA at an exchange rate of 5 dB. The A-weighting
characteristics of these units meet the specifications of ANSI
SI.4-1971, Type 2 devices. Each unit was calibrated prior
.
to each use.
STANDARDS
Occupational exposure standards for airborne contamin
ants as 8-hour time weighted averages (8-hr. TWA) which is
based upon a 40-hour work week.
Some contaminants have short term exposure limits
(STEL) or ceiling limits (C).
The Code of Federal Regulations (29 CFR) part 1910 is
the source of these standards. They are derived from ACGIH
(American Conference of Governmental Industrial Hygienist) ,
ANSI (American National Standards Institute) and NIOSH
(National Institute for Occupational Safety and Health) re
commendations .

Fourty-eight (48) countable samples were taken and no exposure exceeded the 2.0 f/cc TWA-PEL. Only one sample if. exceeded 0.5 f/cc. This level is significant in considera tion of the proposed new standard of 0.5 f/cc (TWA-PEL). Additionaly, 13 samples (27% of the total) exceeded .1 f/cc, and may be of future significance.

UPL NOj_ 2 Hydrotester This operator, K. Hanna (No. 18) occasionally used a
hand held rasp (file) to remove high spots on the outer diameter of both classes of transite pipe (12" and 14"). The residue was brushed off by hand or blown off, thus result ing in airborne asbestos fiber. Interestingly, this job classification is described as a wet-end (WE) area.
Pie_Machine_ (/M) _Crew Members The primary source of exposure at this location is the
build-up of residual material which has escaped the wet-rolling manufacturing stage. This build up was noted to be ubiquitous to the 13' P/M area, and can be loosened during vibration of the machine. These classifications were also previously designated as WE areas. PVC Assembly__Moulders
Manufacturing tasks of this job classification include the assembly of transite couplings as well as plastics products.
At the time of this sampling, transite short heavy tap 12" class 150-200 couplings were being finished by installation of a rubber bushing (ring) into the coupling. The fitting, however, was aided by dry scraping or sanding of the coupling, which can release airborne asbestos fiber. Small. Coupling_Cut-Off_Saw_0erator
Cutting activity involving 13* transite pipe into 7" sections of class 150 resulted in a build-up of shavings beneath the pipe which is not locally exhausted. The local exhaust
D 002361
Page 13
above the pipe, at the cutting area appeared to work well.
However, during loading/unloading of the cut transite
material, dust was generated.
Coupling_Tester
Although couplings were wiped clean with a damp sponge.
the transferring from pallets to the testing unit disturbed
settled dust.
Quality Control JQC)_Crush_Tester
Fiber release may have occurred during the crush testing
of 1 * sections of transite pipe in the testing laboratory.
Additionally, bulk fiber and blends were checked by this
operator.
2-Fork_Truck_Driyer
Exposure most likely resulted from handling of finished
product at the mono saw area.
Mn_Saw_0erator
5" class all sewer pipe 45elbows were run during sampl
ing. Exposure resulted from dust generated by the cutting bit
and dust observed inside the saw housing room. A 3M 9920 Dust/
Fume/Mist respirator was worn upon entry in the room. Thus,
protection for part of the sampling period was afforded.
Respirable-Silica Xsi2)_Dust
Thirty (30) total respirable particulate samples resulted
in low levels of respirable silica exposures except for one.
Only one sample (No. 2222) , placed upon M. Bartley (MOA lathe
operator) on 9/26/83 exceeded it's calculated PEL. The level
D 002362
Page 14
of 0.5 mg/m3 exceeded the calculated PEL of 0.39 mg/m3. Lathing activity at this MOA lathe was unique when compared
with the other lathes. Full pipe length OD lathing was done here. Thereby, greater quantity of dust material was expected. However, observation suggested that this dust was finer in character as well. Vinyl Chioride_Monomer_-_All_Areas
The results in Tables V through VIII indicated non-detetable levels of VCM for both personal and source exposures (<0.2 ppm) . Tta_l Part_iculates_-_Batchin2 Operators
Batching operators R. Price (No. 2108), PVC area, and K. Wingfield (No. 2229), Injection Molding Area are receiving less than 15% and less than 2%, respectively, of the PEL of 15 rrtg/m^ for nuisance dusts.
Additionally, the stabilizer component (liquid Butyl Tin) which comprises 1.3%.by weight of the total batch is added via an enclosed feed system. In view of the total particulate exposures and the small amount of tin in the mix, it is unlikely that exposure to the tin would exceed allowable limits. Carbon_Monox_ide
Personal exposures ranged from 7.2% to 19.5% of allowable for a time weighted average. Instantaneous readings indicated that short-term peak concentrations were present in locales immediately after propane powered equipment had operated in the area. There levels ranged from 0 to 10 parts per million.
D 002363
So 1vent_Vapors - All. Areas
The solvent vapor results reported in Tables III and IV
were unremarkable in that no result approached any respective
PEL, even when additive effects are considered.
One methylene chloride result for T. Beck, permastran
winder operator (sample No. P-1) was 42.6 ppm (8.5% of TWA-PEL)
this was the highest percent of allowable detected.
Noise
.
Personal noise dosimetry results are of primary concern
as this was the area of greatest non-compliance with respect
to 29 CFR 1910.95.
Thirty-nine (39) of a total of eighty-two (82) samples
(47.5%) equalled or exceeded the 90 dBA TWA-PEL.
By areas, the breakdown is as follows:

It would be prudent to include all job classifications in a hearing conservation program. Encouraging the use of ear plugs or muffs and enforcing their use should be an element of this program, as inconsistancies in the wearing of hearing protection were noted in several areas of the facility.

RECOMMENDATIONS Asbestos
1) Dry filing and sanding procedures should be discon tinued, as fiber release has been demonstrated by this activity. Wet methods should be investigated.
2) Improved maintenance with regard to the 13* pipe machine with attention to the removal of built-up fibrous material should be undertaken.
3) Ventilation surveys should be conducted at the small coupling saw and mono saws to determine the effective ness of the local exhaust systems.
4) Review methods of fiber sample collection and testing for Quality Control personnel. Respiratory protection may be needed during the actual collection and test- ing. Sample-No. 38 includes this activity. The fiber sample collection work should be separately sampled next time for assessment of peak exposure potentials.
5) Improved control of scrap and residual material present at coupling tester, mono saw, small coupling saw and 13' P/M should help bring exposure levels down. A regular program of housekeeping throughout the shift is advisable.
6) Annual monitoring should be continued.
D 002365
Page 17
Respixabl.e_Silj.ca. Dust_
1) Resampling of the MOA lathe operator should be done to confirm the level obtained in this survey.
2) Overall, sampling results did not indicate any levels of concern with regard to respirable silica dust. Monitoring on a comprehensive scale does not neejj
to be repeated, as long as changes in processes or
materials are not made.
Totaj Partjculates_
1) Batching operations, as sampled, did not result
in high exposure levels. Resampling may be conducted
if a greatly increased workload or alternate materials
are used.
Vinyj Chloride_Monomer
1) As long as the PVC received from suppliers has no
more free monomer in it than was present during this
survey there is no further need for VCM air sampling. ^
Solvent Vaor
1} If working conditions, equipment, practices and mat
erials did not change, there is no further need to
sample the use of the various solvents during pro
duction activity. Since employee
r
^ted that vapors are "increased"
during hot weather, sampling should be done to assess
the levels encountered during the hot weather.
D 002366
Page 1S
Cajljijon_Monoxide
1) No changes appear necessary at this time.
Noise 1)
The feasibility of engineering control of noise needs
to be assessed.
2) The hearing conservation program must include, as a
minimum, the following elements.
A) Periodic monitoring. B) Baseline and annual audiograms.
C) Hearing protectors; supply and enforcement of use.
D) Training.
E) Recordkeeping.
