N.I.O.S.H. industrial hygiene surveys in 1967 andtl970 yielded- grossly excessive fiber concentrations compared to current and proposed, asbestos standards, and those results were forwarded to the coupany for-appro priate action. Tollowing requests for evaluation and assistance, froa the Texas State Health Department and the local membership of the-Oil. - Chemical and Atonic Workers International Onion, N.I.O.S.H. conducted: a conorehensive industrial hygiene and medical survey during the week of October 26 to 29, 1971.
The survey pointed out major Industrial hygiene deficiencies which included a grossly inadequate ventilation system and poor housekeeping practices. In August 1971, respirators were made mandatory in all areas concomitant with application for variance from the current asbestos standard; however, our survey personnel observed many employee* with loose or unconnected straps. Also, there was no program^or- the fitting and maintenance of respirators. Again personal air scnplic yielded grossly excessive fiber concentrations in all production, finishing, and shipping areas.
N.I.O.S.H. medical questionnaires and examinations for rales and finger clubbing were conducted by our survey team on 63 employees In order to complement the X-rays and pulmonary function tests performed by Dr. George Burst of the East Texas Chest Hospital In August 1971 at the request of the Pittsburgh Coming Corporation. One film was read S3 a pulmonary neoplasm by Dr. Burst, and this diagnosis was confirmed following hospitalization. In addition, several films were read as possible

VEKTI NATION systc-i analysts
An evaluation oE ventilation system problems was mad by Joiut P. Boyle on November 29, 1971-
Tne overall system analysis was based on several different factors of which the following items ware considered:
1. System air handling capacities were evaluated by talcing pitot . traverse data in the major exhaust ducts with an Alnor veloaeter and 18" pitot probe attachment.
2. Capture velocity data was monitored at all hood openings.
3. lack of confinement was determined from comparison of exhaust
air quantities at hood openings versus the amount of air being handled by the system.
4. Housekeeping and uncontrolled dust sources were used as indicators
on the efficiency of the system confinement and ventilation efficiency.
Gross housekeeping violations end other dust sources were recorded by photography.

OBSERVATIONS:

1. System confinement is very poor. Hood air flow for feeder systems No. 1 end No. 2 were found to be 659 cfn where the exhaust duct for this system was handling 2,060 cfm. Ihe same condition was noted at Feeder Unit No. 3 where air flow at the hoods dropped down to 855 cfm from an exhaust air flow capacity of 1,690 cfm. Therefore, actual system leakage accounts for an efficiency of 50% or more.
Conditions noted included the following:
a) The backs from the feeder units had been left off.
b)
3 Cover places to access ports for equipment drives were, missing
or lVij r
*o
c) Inspection openings were broken, and left open.
h" < 4 ^
2. Ventilation control of asbestos fiber dust was practically non existent.
Z LU
a) Capture velocities were not maintained at the feeder hoods.
b) There was considerable spillage of dust from feeder openings (backs, drives, inspection ports, hoppers.)
C.3 o o
,
c) Spillage from the feeder transfer belt system was found to be to
a continuous dust source.
"S'1-
IK*
d) The bag filter unit from the dust collection system discharges
air back into the building. Such a filter can not remove all the fine * *
dust and is a source of personnel exposure.
LU
c.
3. The system air flow is too low to prevent settling out of fibers inside the exhaust ducts. This is a design problem which requires
o z
correction since system pluggage occurs, and then there is a total lack of dust control.

Note: The twelve-inch duct to Builder Units No. 2 and No, 3 was almost plugged at tine of test, such that the duct capacity was greatly reduced.
Observations:
1. Dust in the builder area is confined to the builder machines by a negative pressure. Openings are snail and confinement is good except when exhaust duct pluggage occurs.
2. The ovens at the south end of the builder area are exhausted to the outside. Each unit handles approximately 8,000 cfm. Opening capture velocities are adequate for dust confinement (125 to 300 fpm).'
3. The bag filter unit located just north of the builder machine work area seems to be the principal source of fiber dust contamination in this area. Dust is pulled through the work area by the oven exhaust systems on the south side.
4. Equipment cleaning is a second principal source of dust contamination. Extensive housekeeping is required to minimize such problems;

The small, intermediate and large saws are on one exhaust system with

a bag filter located outside the building. Each saw has a blast gate
for shutting it off when not in use. The exhaust system is used for one^v^'

Observctions:
1. Hood uxliaust quantities approximate the overall air volume being handled by the system. Therefore, system leakage is negligible.
2. Visual observation indicated a lack of ventilation control during part transfer between cutting operations. Better confinement is indicated.
3. Considerable floor contamination occurred during usage of the saw. Cleanup was not made directly after completing the job. Floor contamination is one of the biggest sources of contamination in this area.
A. Floor contamination is blown by pneumatic system.piping vents which discharge under the saw conveyor belt location.

1. Hood exhaust quantities approximate the overall air volume being handled by the system. leakage is negligible.
2. Visual observation indicates a lack of ventilation control during part transfer between cutting operations. Such control is totally lacking when the outside door East of the intermediate saw is opened. The employees open it most of the time.
3. Floor contamination was not cleaned up immediately after use.

Existing Control Pm^mnut
The following information was submitted by Mr. Charles Van Home at a closing conference with J. 2. Boyle and C. R. Holder:
(1) Respirator Program
"All personnel in production areas of the plant are required to wear BMS Approved Respirators, MSA Dustfoe Ultra filter cartridge Type A, which are 99.937, efficient for 0.3 micron particles, dusts, mists, fumes, smokes end extremely fine toxic aerosols and/or radioactive materials."
a) All personnel were noted to be wearing such equipment in production areas.
CO
b) Approximately 30 to 502 of personnel do not wear the respirators properly. This was brought to Mr. Van Home's
CD
attention. He was requested to contact vendors for proper recommendations and to correct this deficiency.
Q_
-
Mr. Van Home stated "vendors will be contacted and your recommendations*',.^
will be followed today. I shall notify my supervisors immediately of
your comment on respirator usage."
.
The immediate potentially serious hazard for production personnel is controlled by respiratory protection.
":L UJ
nf
Mr. Holder asked if e prephysical examination were required for new men. I'--.
Van Home indicated that this practice had been discontinued for the
,'1
past two years. He was advised that under these conditions he would be
unable to determine if the new men were physically able to wear a
VTM.
respirator.
O
o
(2) Possible substitution of material
Question - What progress has been made on coming up with an alternate or substitute material?
Answer - Of course we plan to shut down the plant on January 31, 1972, and the men have already been notified.
The use of mineral wool as an alternate material was researched for
16 - 18 months. Not very good when procedures similar to asbestos operations are used.
A new roll up procedure for mineral wool is no good due to quality and economics.
GG lo970
L^0902d'J
''I
ATTACHMENT #8 Page 2 f 2
A recent cast process for mineral wool shows some promise. The initial cost is high.
Pearlite may be the answer for substitution. It shows some promise.
Mr. Boyle indicated that Pearlite is a silica product.
(3) Product usage by G.S.A.
o </
O' ^
, 1I
Although asbestos fiber is not readily available and Pittsburgh Corning is planning to stop plant operations, it should be noted that GSA has
stockpiled large quantities of asbestos insulation. . It is currently used in many maritime operations.
(4) Shut-down procedure
.
Rework of large inventories of scrap will not be a problem. The percent of scrap in the product is high (25Z) and inventories of scrap are low.
Orders are not being taken now. The schedule is normal.
"*
o
f*
Several men will have to clean equipment after shut-down. (5) Vacuum Cleaner Usage
An industrial vacuum cleaner has been purchased (Billy Goat Unit) and has been in use for one and one-half yeara. The unit comes with special bags. No test has been made to determine th bag collection efficiency.
(6) Medical Program
Dr. Grant is the PPG advisor. Dr. George A. Hurst, who is Director of the East Texas Chest Hospital, has been retained to conduct the plant medical program.
a) Pulmonary function tests and x-rays are required for all personnel with one or more years of experience.
b) Records are available through Mr, Van Home upon request. This information has been given to NIOSH. The data was reviewed by Mr. Boyle
