Dear Ms, Gerard:
,
On May 31, June 1. end June 3 an industrial hygiene survey was conducted
at the Dayton plant oy this writer with the assistance of Bob Prim, industrial Hygienist, and Dan Bentley, Engineer. Sampling at the Tipp City plant was completed July 26, 1983 and will be the subject of a separate report.
Sampling and analytics!I methods used are discussed in .A ttachment 1.

These values represent exposures only under the conditions and production levels found during this survey and may vary considerably under other conditions, particularly in the winter months.
Caution must also be used in applying respirable "nuisance dust" standards
tosarne of the chemicals which are handled by the compounders for which little,
if any, toxicological information is available. Of concern specifically arc the
powdered preservatives and fungicides used, for which sampling methods are not

Of more immediate 'concern is the lob report of approximately 1-3% Iremolitc asbestos in a bulk sample of talc (Code 22) which was in use during the survey. The respirable dust values cannot be used to project asbestos exposure levels. Asbestos monitoring must be conducted in accordance with the OSHA regulation 29 CFR ISL0.10D1, (Attachment 3).
Due to the lack of local exhaust ventilation for compounding areas and due to the extreme health hazard posed by asbestos exposure, it is recommended that use of this particular tale: b e e lim in a te d .A s we understand the situation, ; . there are several., suppliers. oT Code"22, most -of'- Who. state'-Pi-m aterial safety data sheets that the tnlc is non-fibrous. According to our conversation during the Tipp City survey, the talc in question was supplied by VnndorbiJl. The inb reports an approximate i 25% accuracy in determining the asbestos content of a tale bulk sample by polarized light staining microscopy. The ehomisl slated that the manufacturers generally are not using the criteria of a 3:1 Icnglh-lodiamrter ratio in determining asbestos content, and thus their reports oT asbestos content are generally lower.
If use of Ihc Vunderbilt tnlc continues, initial monitoring of employee exposure is required by the current OSUA asbestos standard. The Director of the Occupational Safety and Health Administration recently described the 2.0 fibers per cubic centimeter permissible exposure limit (t'KlJ ns "insufficient to prevent cflneer, nt least in some cases." lie projected that revision of the PHI. and issuance of n final rule should be completed later this year (1983).
. .. . .In the. interim and . until .initial monitqnng- results urn. .available,- i t is recommended D in t, in n re ris / where .the asbestos-containing '.tnlc-.'is in//use. employee use of respirators approved for protection against toxic dust including asbcslos (not the 3.M 8710) become mandatory and (hat strict housekeeping practices for dust control be Implemented. Dry sweeping of dust containing asbestos is prohibited. Clean-up methods include wot methods which prevent reintroinmenl of the dust after the water hos evaporated nr high-cfficicncy filtered- vacuum systems. (Attachment f for .illustration purposes only) .
It is also recommended that since asbestos had been used to a much larger extent in the past, an effort be made to identify those employees who incurred exposure nnd to place them in a medical surveillance program. Such a program would include an annual or semi-annual physical examination, pulmonary function testing and chest X-rays. Implementation of such a progrnnt may lead to curly detection, and thus' early treatm ent, for asbestos-rein led disease, perhaps reducing the suffering nnd costs now associated with asbestosis and cancer. Yon may wish to contact the.Kettering Lob of. the University of Cincinnati College, of Medicine, the (tit. Sirinf School of .Medicine in New York, or the National Institute for Occupational Safety nnd Health (NIOS1I) In ' Cincinnati. Ohio, for ' information concerning a medical surveillance program.

The following paragraphs regarding asbestos have been summarized from
several resources. Much additional information is-available-through contacting
our Resource Center in Columbus, Ohio, a l l . (800) 232-3045.

:

"VV;T, ....... ' '
Asbestosis is a progressive restrictive pulmonary fibrosis associated with inhalation of asbestos fibers. Malignancies related to the inhalation and possibly ingestion of asbestos fibers by epidemiological studies include carcinomas of the lung, mesotheliomas of the pleurs and peritoneum, and noplasmes of other sites.
Asbestos has a synergistic effect with cigarette smoking in producing CBrcinoma of the lung. Asbestos workers who arc smokers have over 30 times the risk of non-exposed non-smokers of contracting lung cancer.
Although respirator use is now considered voluntary in the compounding
area, a physical exam to determine if an employee is capable of wearing a
respirator is standard practice. Such a determination is required by the 1980
ANSI standard Z-88.2 paragraph 3.5.3 ond is referenced Irt the OSHA standard 29
CFK 1910.13-1. In regard to your question on OSHA enforcement activity on this
m atter, the Industrial Hygiene Department of the OSHA Cincinnati Area Office

generally cited without documentation of overexpesures,'however the situation
would be evaluated on a cose^-by-case basis with factors such as working-force
age, smoking history, history of cardiovascular disease, heal stress, and past
exposure to toxic chemicals considered. -
/
.
. Regardless o f Federal policy in; enforcing .or not-cniprcingithis standard;, the determination by a physician that an employee should not suffer additional cardiovascular or pulmonary stress or experience other physical problems before he or she is given a respirator to wear is important in protecting worker health and possibly in reducing future occupational disease claims. Such an exam also provides an excellent opportunity to review selection, fitting, cleaning and
storage practices included in a respiratory protection program.
The nature of some of the materials handled in the Dayton plant presents the opportunity for th e ; development of dermatitis. It was. ..observed that cleaning of. Hie .Dutyl-fiex line was .'conducted .byi.empioycs.' wlu1 were not wearing protective gloves. Solvents cari dfat the skin causing dryness.- irritation and cracking which can be complicated by infection. Additionally, some solvents enter the bloodstream through the skin, the skin acting as a route of exposure.

. Norval Phillips, a compounder, complained o f a "poison-ivy" type rash after using Napocide N-40-D. According to. the material safety data sheet this materia!, is a skin irritan t and;.."causes an increased tendency to become allergic."
Apparently, the manufacturer ijs''sta lin g the fungicide-is a sensitizer. We observed that Norval used disposable-clothing, a dust mask, and gloves when adding Napocide to the batch.. 'Such strict measures to prevent skin contact should be implemented among all'compounders who handle Napocide. and those

'the-.
classification of dusts as nuisance or "inert" can be misleading and a more
correct implication would be th at such dusts do not cause pulmonary fibrosis,
physical Impairment or disease." Inert dusts do not produce fibrosis, but
Increased airway resistance can result from excessive mucous production
stimulated by the deposition of inert particles on the surface of the upper
airways. Although exposure to such dust may not be as potent a factor in
causing chronic bronchitis and emphysema as cigarette smoke, there is some
evidence according to Patty that "occupational dust" may at least contribute to
chronic bronchitis.
The ability of the Napocide to cause allergic reactions illustrates our introductory cautionary statem ent concerning the classification of such ma terials in their dry form as "nuisance dust." In general, fungicides and preservatives must conluin one or more biologically active ingredients in order
to be effective.

The m aterial'safety data 'sheets provided little toxicological information for
these chemicals, but all were listed as eye, skin, or respiratory irritants. Until
information is available to the contrary, it should be assumed that inhalation of
or skin contact with these materials may elicit a negative response in humans.
Use of adequate protective equipment including protective, clothing and gloves, .
respirators, and goggles is advised.

Employees In this area should be included in a hearing conservation program as outlined in Attachment 5.
Control of compressed air noise from the straight tubing used to move ports along this packaging line might reduce employee exposure to a point where a hearing conservation program is not needed in this area. A longer sample is needed for the Butyl-flex packaging line.
Due to resource limitations, we cannot conduct an annua! industrial hygiene
survey; however, we will try to assist you in monitoring specific processes as
requested. Our three-day survey did not enable us to sample several operations
which are of interest. One of these is the premix compounding for Butyl-flex
in which the "rubber hog" is used. The noise and dust from this operation was
the subject of more than one complaint by employees. The operation wbs
scheduled for June 3, 1383, but was cancelled when an employee did not report
for the-firsi . s h u i . ^

However, given the choice between obtaining total dust samples end respirable dust samples in the limited time available, we chose to sample for respirable dust since this more accurately represents the amount of dust which enters the deeper portions of the lung. The filter contained in the 10mm nylon cyclone used is generally considered to capture particles of less than 10 microns in diameter which rrc defined as respirable.

. Respirable, dust samples were collected oh tared PVC filters contained in 10mm nylon cyclones. The'cyclone 'was placed, in the breathing zone of the.; ; , worker by,attaching it to his or her collar.' Tygon tubing connected the cyclone.'
The cyclone separates the dust Into the respirable portion (particles with an aerodynamic diameter less than 10 microns), captured by the filter and the nonrespirnble portion (particles with an aerodynamic diameter greater than 10 microns), which is collected in the grit pot and discarded. In general, particles larger than 111mm are trapped in the nasal passages, throat, larynx, and bronchi from which they are expectorated or swallowed. Particles less than 10mm can be deposited in the terminal recesses of the lungs which allows interaction with delicate pulmonary tissues.
Total dust samples were collected on tered PVC filters with Model G MSA pumps for power supply. Doth types of samples were submitted to on accredited industrial hygiene laboratory where they were analyzed for weight gain.
Bulk samples were analyzed far silica content with X-ray diffraction and for asbestos content with polarized light staining microscopy. Less than 1% -aunriz.wss found, in the bulks submitted. Asbestos content of the tele is

The results reported "as hexane" are used by the lab to report con centrations of mixed petroleum solvent vapors other than those specifically requested. For example, mineral spirits, VM4P napthc and similar materials may contain 15-50 different components. A mg/M3 value can be obtained for mineral spirits or VM&P naptha when a bulk Is submitted for analysis and no other specific chemicals are requested.

Instantaneous sound pressure levels were evaluated with a General Radio 1988 Precision Sound Level Meter and Analyzer calibrated before and after use. Instantaneous measurements are made to confirm tests made with dosimeters and to map areas where workers may be overexposed to noise,(See Table G)
Attachment 2
"Applicable Occupational Health Standards"
Standards and guidelines from three different health organizations Slave been displayed in the Tables. Probably the most familinr of these is the Occupational Safety and Health Administration (OSHA) -- the promulgator and enforcement agency of occupational health laws. In it 's 1970 inception OSHA adopted the threshold limit values (TLVs) established- by ipe American Con ference of Governm ont al Industrial Hygignists (ACGIH). forning-, the - foundat ion of their 'occupational x p t^ e ~ f g te fi6ris.!: OSIA. however,' unlike'the' ACGIH does not have the immediate flexibility to change or update a particular standard without first submitting it for congressional approval or the issuance of an emergency temporary standard. Thus, only a hand full of compliance standards have altered since OSHA's inception (i.n. the standards for lead, vinyl chloride, noise, etc.). On the other hand, the ACGIH reviews annually their TLVs in light of current research developments, epidemiological studies, clinical evidence, and laboratory experiments making appropriate changes when a guideline appears deficient. Furthermore, the ACGIH qualifies their guidelines in slating that
"Threshold Limit Values refer to airborne concentrations of substances and represent conditions under which it is t>elloved that nearly all workers may be repeatedly exposed day after day wihoul adverse effect. Because of wide variations in individual suscepti bility, however, a small percentage of workers may experience discomfort from some substances at concentrations at or below the threshold limit; a smaller percentage may be affected more, seriously.. . , - , by aggravation o f pffr-existirig^condftion o r;by development of "an ; r . occupational'illness. Th TLV-TWA shoiiid be used as guides in the control of health hazards and should not be used as fine lines between safe and dangerous concentrations."!.
The National Jnstitulc for Occupationni Safety and Health or NIOSHTn turn is OSHA's supporting research organization. Under the J 970 OSIMct, NIOSH is responsible for identifying occupational safety and health hazards, for de termining methods to control them, and for recommending Federal standards to limit the hazards. The NIOSH proposed standards, based on much oT the same information as the ACGIH TLVs, ore standards to be considered by OSHA for future promulgation in providing optimum protection for workers.

"Summary of Hearing Conservation Standard"
Monitoring
.
.
The hearing conservation amendment requires employers to monitor
noise exposure levels in a m anner.that will accurately identify employees
who are exposed to noise at or above 85 decibels (dBA) averaged over, eight
working hours, called an 8-hour time-weighted uvernge (TWA). The exposure
measurement must include all noise .within.an 80 dBA to 130 dBA range and
must be taken during a typical-work situation. ; - '
. \ .
...Under, ;Thei.Tevised:;:Bmehdment
mbiiitoring 'procedures "and~they
the *reSultsi of^ the
exposure monitoring of their workplace. The method used to notify
employees is left to the descretion of the employers.
Audiometrie Testing
Audiometrie testing not only monitors the acuity of an employee's hearing over lime, but also provides an opportunity for employers to educate employees about hearing and the need to protect it. The important elements of an audiometrie testing program include baseline audiograms, annual audiograms, training, and follow-up procedures. Audiometrie testing
must be made available to all employees who have average exposure levels over an 8-hour period of 85 dBA. And the audiometrie testing program follow-up should indicate whether hearing loss is being prevented by the employer's hearing conservation program. A professional audiologist, and
otolaryngologist, or a physician must be responsible for the program. Both professionals end trained technicians may eonduct audiometrie testing.
A. Basel ine Audiograma ^
The baseline audiogram: is the reference, against which future . audiograms are compared.. Baseline audiograms- must be provided
...: within B months of an employee's first exposure a t or above an 8-hour TtVA of 85 dBA. Where emplcyers:are;,using mobile test.vans to obtain audiograms, baseline audiograms must be completed within one'year after an employee's first exposure. If delayed for one year, Ihe exposed employees must be issued and fitted with hearing protectors to
be worn until the baseline audiogram is obtained.
B. Annual Audiograms
'r`- mnual audiogram must be conducted within one year of the
. base! Annual audiograms must be,routinely compared to baseline
: '> audiograms to de^rm ine - whether.The .audiogram is- ace urate an d ;to .
determine whether.tbe empibyeVhas :lost: hearing-ability (that is, i M :
standard threshold. shift (STS) has occurred.)- ...STS is defined in the
amendment as an average sh ift'in either e a r1of 10 dBA or more at
2DD0. 3000. and 4000 Hz.
. . v. ; '
'
Attachment 5 (Continued)
til. Audiogram Evaluation
If an STS Is identified, employees must be fitted or refitted with
adequate hearing protectors, shown how to use them, and required to wear them. Employees must he notified within 21 days from the lime the determination is made that their audiogram results showed an STS. If subsequent audiomelric tests show that the STS Is not persistent, employees whose exposure to noise less than a TWA of 9D dBA may discontinue the wearing of hearing, protectors, . v
IV. Hearing Protectors " . ' "" ................. r
,
Hearing protectors must be available to all workers exposed to 8-hour
TWA notse levels of 85 dBA or more. This requirement will ensure that employees have access to protectors before they experience a loss in
hearing. Hearing protectors must be warn by: 1) employees for any period exceeding S months from the time they are first exposed to B-hour TWA of 85 dBA or above until they receive their baseline audiograms in situations whore baseline audiograms are delayed because of mobile test van con
venience; 2) employees who have incurred an STS since these workers hove demonstrated that they are susceptible to noise; and 3) employees exposed over the permissible exposure level (PEL), and 8-hour TWA of 90 dBA or above.
Hearing protectors must adequately reduce the severity of the noise level for each employee's work environment. If workplace noise levels increase, employees must be given more effective hearing p'oteeiors. The .protector must reduce em ploytoexp^ures to a l l east 90..dBA and to 85
' dfiAwhbrv cfSTS ;hds`alfepdy.-dcciifid,-itr:^thei.wdrker.'s hearing must be shown how to use and care for th eir'p ro tecto rs and must be supervised an the job to ensure that they continue to wear them correctly.
V. Training
. . . '
:.
Employee training Is very important. When workers understand the ' reasons for the hearing conservation program's requirements and the need to protect their hearing, they will be better motivated to participate actively in the program. Employees exposed to TWA's of 83 dBA and above must be trained at least annually in the effects o f noise, the purpose, advantages, and disadvantages of various types of hearing protectors; the
selection, fitting and core of protectors; and the purpose and procedures of audiometric testing.
VI. Recordkeeping
- ..
...... . .. . .
Noise exposure measurement records must be kept for 2 years. Records
;of "audiometric test results -m ust. be ' maintained . for the duration of
employment of ,,iie affected employee.-; Audlometric' test records must
..:. ..include 'th e .name nnd job class! Heation,of the.employee, the date, the
examiner's name, the date of acoustic or exhaustive calibration, measure-,
ments o f the background sound pressure levels in. audiometric test rooms,
and the employee's most recent noise.exposure measurement..
