Dear Sirs
The 120-day extension for comment on the proposed revision to the, OSHA asbestos standard; from December 8, 1975 to April 9, 1976, has permitted this Association the time necessary to sponsor an in dustry-wide review of the proposal and its effect on the asbestos using industry within the United States.
The analysis, comments, and recommendations pertaining to the pro posal are respectfully submitted in an industry effort to cooperate
fully with the Department of Labor in tHe'sdevelopment of a reasonable and practicable standard for the prote'ctrLon of workers in thousands of work places, where asbestos producfcs^.are manufactured or other wise processed. The task force ef fort>\reached out to all sectors of the asbestos industry, excepting'^construction. The results of this work are contained in the two volumes, appended hereto. The * first volume contains summary comment's and recommendations prepared by the task force chairman, Guy G. Gabrielson, Jr.; a statement on the scientific-medical issues raised in the proposal prepared by Hams Weill, M.D.; and detailed comments on the .proposed standard prepared by the Standards and Technical Committee of the Association under the chairmanship of Harrison B. Rhodes, Ph.D. The second volume is the technological feasibility and economic impact study prepared by the independent consultant firm, Roy F. Weston, Inc.
We shall be pleased to further communicate or meet with any officials
within OSHA to discuss the findings and recommendations presented
herexfith.
'
We believe a public hearing on this matter will best serve the in terests of asbestos workers, the employers within the industry, and the general public. We request a.public hearing at the soonest practicable date.
Sincerely yours.

Comments of Proposed OSHA Standard - OSHA has received 180
responses as of April 9 public comment deadline on proposal
to revise asbestos standard for permissable workplace exposure
level of 2 fibers per cc of air, TWA as of July 1, 1976 to 0.5
f/cc, no date specified. Radical proposed.lowering of standard
was based on premise that "sufficient medical and scientific
evidence has now been accumulated to warrant the designation of
asbestos as a human carcinogen", and "there is no assurance of
a safe exposure for a substance with known carcinogenic property
... there should be no detectable concentrations." In proposing
h fiber level OSHA noted it must take into consideration tech
nological and economic factors.
'
AIA/NA industry response, endorsed by 79 individual companies
and 15 trade associations, concluded:
-
" Since there is not credible medical evidence to indicate that the 2 fiber standard will not be adequate to protect the health of employees during a working lifetime, there is no present justification for a lowering of the 2 fiber standard."
The AIA/NA response stated that the industry could provide equip ments and.programs to achieve a 2 fiber level and urged its re tention as reasonable and practicable. A 0.5 fiber level was termed "not feasible." The recommendations of the industry response were supported by an authoritative review of the medical and scientific issues raised in the proposal, an extensive independent study of technological feasiblity and economic impact of the proposal and item by item review and recommendations on the proposed regulation.
A sampling of comments from industry among the 180 responses these:
" We oppose the institution of crippling or impossible work requirements that are not founded on factual, reliable and reputable evidence."
are
'
"... that such irresponsible legislation can only serve to confuse, demoralize and frustrate small business everywhere...a more moderate approach would be beneficial to both labor and industry. n
n We feel that OSHA has lost all touch' of reality in reference to the impact this proposed reaulation would have on our industry..."

measured." At sometime AIA/NA urges public
hearing on standard(s) at earliest practicable
date.

In discussing matter with AIA/HA representatives. Assistant Secretary of Labor (OSHA) Morton Corn stated he did not question wisdom of concurrent consideration ' but feasiblity and economic impact studies of construction industry had yet to be accomplished. He said schedule for completion of regulation for manufacturing industry should not be further delayed. Date for Asbestos sub group of OSHA's Construction Committee to discuss problems of construction industry as related to proposed standard have not been announced. Presumably there will be a meeting in May. - An inflationary impact study will be required. Meanwhile, it is of interest that present terms of Construction Committee members expire June 30, 1976. Some present members may be reappointed.
As to timing for public hearing for proposed revision to "manufacturing" standard, inflationary impact state ment being developed by consultant firm, CONSAD of Pitts burgh, has yet to be submitted to OSHA in final form. Rulemaking process requires statement must be available to public at least 30 days before public hearing. It may be concluded public hearing on proposed revision to standard can not be scheduled before end of June at earliest. Other considerations and pressures on OSHA may delay date much further into year.
Asbestos Ban Not Needed - Appearing on NBC Today Show March 31
Dr. Irving J.Selikoff, Professor of Environmental Medicine, Mount Sinai Hospital, New York City, stated that if asbestos fibers
are contrlled, they do not have to be banned to protect society.
"There are many valuable things in our society that we can't
really do without. Once we know what can cause cancer, we can
do a great deal to control them without banning them outright,"
the well known medical spokesman on asbestos stated. (See clipping
attached.)
.
Asbestos in Drinking Water - Environmental Protection Agency called news conference 2pm April 30, 1976 to advise full room of reporters and cameramen that EPA .had found measurable amounts of asbestos in some treated and untreated water samples in some cities and not in others pointing out that "it has become increasingly clear that the techniques for identification and measurement of asbestos in water are not as precise or accurate as we would like."

improved technical ability, increase in the quantity and quality of standards and improved cooperation with industry for a realistic program of safety and health in the workplace.Federal health compliance officers are to equal the number of safety compliance personnel now numbering just over 1000. Standards development personnel are to be- increased with con centration on industrial medicine and toxicology expertise. A technical data center for toxicological information and program support for standards development and abatement activities is being formed. OSHA has ordered large quantities of monitoring, testing and other equipments for field as well as laboratory use and is searching for better tools in these areas.
_
At a press briefing on April 19, Corn advised that plans to re organize OSHA's top staff echelon to provide for better functional and administrative competence would be in effect by August. In further attempts to overcome the image of bureaucratic inefficiency. Corn is paying increased attention to the safety and health prob- . lems of small business, encouraging on-site consultative services, adding new emphasis to public participation in rule making and advisory capacity and holding regular news conferences.
Dr. Corn deserves best wishes as OSHA enters its sixth year.
It is hoped that his leadership and professional competence will pre
clude the repetition of arrogance, subjection to pressure and im
proper evaluation of information which led to the infeasible, im
practicable and unnecessary proposal for revising the asbestos
standard.
.'
The month of April also marks the fifth anniversary of the incorpor
ation of AIA/NA as a non-profit organization of asbestos using manu
facturers, miners and other asbestos interest companies to, among
other objectives, "provide industry-wide information on asbestos
and health and on industry efforts to eliminate existing hazards
and to cooperate with governmental agencies in developing and im
plementing industry-wide standards for worker protection and for
the conttol of asbestos dust emissions into community air and water."
The Association can take pride in its achievements. Its membership
growth is indicative of its service and importance to the asbestos
industry.

Administration Opposes Mine Safety Transfer - Assistant
Secretary of Interior, William L. Fisher told Senate
Labor Subcommittee on Mar. 25 transfer of responsibility
for mine safety (MESA) from Interior Department to Labor
Department is opposed by Administration. Testimony was
given at hearings held on bill (S. 1302) introduced last
Mar. by Sen. Harrison A. Williams, Jr. (D-NJ), chairman
of subcommittee. According to Fisher, Administration ob
jects because bill "fragments the ability of the Executive
Branch to effectively administer our nation's energy and
mineral resourse program by stripping the Secretary of
the Interior .
and transferring that authority to
another department." S.1302 states MESA would be inde
pendent of OSHA in Labor Department.

ASBESTOS INDUSTRY CALLS PROPOSED 0.5 FIBER RULE
Occupational Safely and Health
INFEASIBLE; CITES LACK OF MEDICAL JUSTIFICATION
Administration's proposed work
, place asbestos exposure standard
of 0.5 fiber per cubic centimeter of air as a time-weighted average for eight houis, with a ceiling
limit of five fibers per cubic centimeter, b not feasible. Asbestos Information Association of North
America, representing the nation's primary and secondary asbestos producers, told OSHA in com
A* ments submitted April 8. Citing the lack of "credible medical evidence" indicating that a standard
/ or two fibers per cubic centimeter as a TWA with a ceiling limit, of 10 fibers will not adequately protect the health of an. employe over a working lifetime, industry urged retention of that stand
ard, which had been scheduled to become effective July t, 1976, under the existing regulations
adopted in 1972.
.
.'r'
/ !? v *
' Admitting that exposure to airborne asbestos has been shown to cause fibrosis among industry
workers, and b associated with "the appearance of an excess of certain cancers," AIA challenged the
concepts upon which OSHA based its stringent proposal, particularly the "theoretical" argument that
individual variability in response to carcinogens b great, so such exposure must be reduced to as
close to zero as possible. Maintaining it would be more responsible public policy "to postulate a
tolerance level for suspected or acknowledged environmental carcinogens, pending definite knowledge
of a .true level of tolerance... than it b to pay the geometrically escaiaung cost of attempting to ap
proach zero exposure," particularly in the case of a useful substance like asbestos, industry called on
OSHA to calculate "a reasonably safe estimate, based upon the best available evidence, of. the leveb
of the substances which man can tolerate" rather than rely on an "unsubstantiated theory" such as
the zero tolerance hypothesb.
:.
Relying on OSHAs willingness in 1972 to promulgate a two fiber standard, AIA emphasized
that no substantial new data have been developed since that time from which it can be concluded
that such a rule would fail to provide a safe working environment for a lifetime. "If a permanent
standard or two fibers/cc TWA was reasonable and appropriate in 1972. and we believe that it was,
it remains reasonable and appropriate today," industry asserted. AIA told OSHA a standard of two
fibers with a 10 fiber ceiling limit b technically and economically feasible, and could be achieved
industrywide in three to five years.

RUM:v
INTRODUCTION
l--
On October 9, 1975 the Occupational Safety and Health
Administration of the Department of Labor proposed a revision to its
regulation, Occupational Exposure to Asbestos, 29 CFR Part 1910.
.
On December 11, 1975 the Board of Directors of the Asbestos Information
Association/North America (hereinafter AIA) voted to sponsor an
asbestos industry response to the proposal and created a task force
for that purpose, naming the undersigned as Chairman. The Task Force
enlisted the support of the membership of AIA/NA and invited non
member companies and trade associations to join in the endeavor.
The result of that effort is this statement, made on behalf of the
companies and trade associations listed as endorsing firms and
organizations.
'
The statement was prepared in this manner:
1. Dr. Hans Weill, Professor of Medicine, Tulane University School of Medicine and medical consultant to AIA/NA, reviewed recent literature pertaining to asbestos and health, consulted with other qualified experts both in the United States and abroad, and prepared a paper, attached hereto, which summarizes the present state of knowledge concerning asbestos disease, giving particular attention to those papers cited in the OSHA proposed regulation.
2. -Roy F. Weston, Inc., an independent consulting engineering
firm of West Chester, Pennsylvania, conducted a survey of the United
States asbestos industry to ascertain the technological and economic
feasibility of the proposed regulation and its economic impact. The
Weston report is attached hereto.
.

--
the premise that there is a dose-response relationship between
i. exposure to most, if not all, carcinogens and the development of
cancer. There is no reason to believe, from the data available to us,
that asbestos is an exception to this generality; although, at this
time, no one definitely can say at what exposure level asbestos
becomes a cancer hazard to man.
.
,
Our review of the literature indicates that no credible
epidemiological studies have been published which would suggest
an excess of malignant tumors among persons exposed to no more than
2 asbestos fibers per cc of air (TWA), using the prescribed membrane
filter test method. This is a fact simply because there have yet
been identified for study no populations the exposure experience of
which consistently has been as low as 2 fibers. Since all populations
studied to date have been exposed to substantially higher concen
trations of airborne asbestos, we can conclude only`that an excess
of all types of asbestos disease is associated with levels of
exposure significantly higher than the level currently mandated
to become effective on July 1, 1976.
'
Technological Feasibility and Economic Impact Study For convenience, the Weston study has divided the U.S. asbestos industry into three sectors or segments:
(a) "primary" - employers who receive, store, handle and process raw asbestos fiber.
(b) "secondary" - employers who receive, store, handle and process products or materials containing asbestos, and
(c) "consumer" asbestos.
employers who use products or materials containing

'
0.5 fiber/cc TWA is technically feasible neither for

United States and abroad and therefore can be observed in operation;

it can be stated as a fact that an 0.5 fiber/cc TWA level of control

is not feasible in the primary or secondary sectors.)

proposed, a ma jor portion of the annual cost of compliance will be that
for the industrial hygiene and medical program; and that burden will
be heaviest in the secondary and consumer segments of the industry.

mandated by the proposed regulation will strain the capacity of

these limited resources.

economic impact upon the asbestos textile and friction products

SECONDARY RECOMMENDATIONS
l
'
EXPOSURE STANDARD
.
The asbestos industry recommends the adoption of a permanent
`
exposure standard of 2 fibers per cubic centimeter of air, time-
weighted average, with a peak or ceiling limit of 10 fibers per
cubic centimeter of air, using the membrane filter test method.
As a feature of its case to justify a reduction of the TWA
exposure standard from 2 fibers to one-half fiber, OSHA, in the
`
preamble to its proposed regulation, states that "In animal studies
it has been found that individual variability in response to
carcinogens is great ***** and then adds, "While some level, below
which exposure to a carcinogen does not cause cancer, may conceivably
exist for any one individual, other individuals in the working
population n\ay have cancer induced by doses so low as to be effectively
zero." In proceeding, then, to the conclusion .that exposure to a
carcinogen must be reduced as close to zero as possible, the argument
does acknowledge that the concepts cited are "theoretical". And
theoretical they are.
.
Although some health scientists speculate that variations in
man's susceptibility to cancer-causing agents may be great and that,
therefore, the level of tolerance of some individuals to these sub- :
stances may be virtually zero (the "one-hit" hypothesis); other
^*ealth scientists argue that the range of variations in the individual
susceptibility of man is small and has been found to be far less significant in the etiology of cancer than the level, duration or
regulatory policy ought to be a reasonably safe estimate, based upon the best available evidence, of the levels of the substances which
man can tolerate and not the adoption of .an unsubstantiated theory
like the "one-hit" or zero tolerance hypothesis.
.
The record shows that the proceedings which led to the adoption
in 1972 of the current asbestos regulation were replete with refc.ences
to the cancer hazards of asbestos. In fact, the standard then
established was chosen in significant measure out of consideration
for the risk of mesothelioma. The preamble states, "* " "because it
appears that levels of exposure which may be safe with regard to
asbestosis are not safe with regard to mesothelioma; * * "the conflict
in the medical evidence is resolved in favor of the health of
employees. As of July 1, 1976, TWA concentrations of asbestos fibers
larger than 5 micrometers will not be allowed to exceed two fibers/cc
* * *." It cannot now be said that the carcinogenic character oi
asbestos is a recent discovery, occurring after the present regu-
lation was promulgated. Clearly the 1972 regulation was adopted to
protect employees both from asbestosis and from cancers of all types.
The permanent standard mandated for that purpose was developed on
'
the basis of medical knowledge then available and was set at 2 fibers
per cc TWA, with a 10 fiber ceiling. The issue which we now face,
then, becomes: Has any new evidence been adduced since 1972 which
would require a change in the standard? We have found no such
evidence.
Our review of the medical literature discloses a proliferation of studies concerning the health effects .of asbestos. In general, they tend to confirm that which we knew in 1972: that exposure

l standard of 2 fibers/cc. TWA., with a ceiling of 10 fibcrs/cc., is
feasible technically and economically.
. At this time, the industry has not achieved a 2 fiber level ..t *' .
all processing steps; but the consensus of informed opinion within
' ,
the industry is that control to that standard can bo achieved by the
application of BAT, BAT being an optimum combination of knrwn engineering techniques and carefully enforced work practices, with BAT in effect throughout the industry, there may be a few process
steps which intermittently will exceed the 2 fiber level, but these
incidents simply will have to be handled as emergencies. The 2
fiber level can be achieved in three to five years, although some
portions of the secondary segment of the industry may require a
somewhat longer period of time to attain a,2 fiber level of
proficiency. Of course, during the three to five year period
required to effect BAT, a constantly declining number of work stations
will be operating over the 2 fiber level for decreasing percentages
of the time.
_
The cost of installing BAT will not be insubstantial, but indi
cations ire that, for the larger part of the industry, the annual
cost of achieving the 2 fiber level can.be added to the cost of
products sold without significant adverse impact upon market position.
Exceptions to this generality may be the asbestos textile and friction
products industries, as well as certain portions of the secondary
industry segment; since, in these areas, aggressive foreign
competition may deprive domestic producers of opportunities for price relief or may extend the already marked penetration of foreign

there will remain many process steps which operate regularly at 1 fiber/cc TWA or higher. For the present, it is necessary to assert as fact that a 0.5 fibers/cc TWA standard is not feasible.
It is the opinion of the asbestos'industry that the selection of an appropriate exposure standard must be influenced by the limitations of the exposure measuring technique to be employed.
Extensive experience with the membrane filter test method, particularly since the 1972 asbestos regulation was adopted, has demonstrated its weakness. As the levels of airborne fibers to be measured decrease, a reasonable degree of statistical accuracy (i.e. + 10%) can be maintained only by extending the sampling time or increasing the number of microscopic fields to .be counted, or both. Of course, these modifications of the testing procedure increase the time required for its accomplishment and increase its cost. At low fiber concentrations the test becomes cumbersome and impractical to use for routine environmental monitoring. In addition, if sampling time is extended in the kind of mixed dust environment which frequently is encountered in industrial situations, the filter may be blinded by non-asbestos particles so that the asbestos fibers cannot be counted. Because of these problems, it is our view that to mandate the use of the membrane filter test method as an enforcement tool at a fiber concentration less than 2 fibers/cc TWA would be inequitable and questionable as a matter of due process.
I Materials and finished product roust move into and out of' regu-
l.ited areas, and employees in most cases must move where materials
and-product move. In the normal course of factory operations, requ* #.
la Led area employees occasionally must leave their areas for brief
periods of time; and non-regulated area employees (i.o., maintenance,
engineering and supervisory personnel) must enter regulated areas.
Regulated area employees cannot practically be required to chanqe
their clothing whenever they leave the regulated area and, indeed,
there is no need for such a change of clothing. It is hiqhly unlikely;
that contaminated work clothing worn into a non-regulated area
ever would create airborne concentrations of asbestos fibers in
excess of any proposed exposure limit, even 0.5 fiber/cc. TWA.
Access to regulated areas properly should be limited to those persons
who have a legitimate function to perform there; and those indivi
duals should be provided with personal protection, if indicated by
conditions in the area where they will work and the kind of activity
which they are to perform. Regulated area employees should remove contaminated work clothing at the end of the day and, of course,
should not wear such clothing home.
The asbestos industry recommendations are designed to make the
rrqulated area concept practical to administer and effective in
restricting airborne asbestos contamination, in excess of the exposure
limits, to those defined workplaces where appropriate personal pro
tection can be provided. We suggest the elimination of the require
ment for a roster of persons entering a regulated area, because such
' record would have no value.in support of employee health programs

METHODS OF COMPLIANCE
t
The OSHA proposal establishes the order in which methods of
_
compliance must be utilized: first, enqineering controls; second,
work practices; and third, personal protection. The rationale
for this ordering of the three basic modes of compliance undoubtedly
is that machinery is not subject to the human failings which may
reduce the effectiveness of work practice controls; and personal
protection may be even less effective, because employees might be
motivated to circumvent the protection afforded by respirators in
quest of greater personal comfort or convenience. This approach
by OSHA to the compliance problem is logical, but we doubt that it
is practical to implement.
Our survey of the asbestos industry indicates that work practices
in most cases are inseparably linked to engineering controls. The
best engineered dust control system must be understood by the people
using it, properly operated, and properly maintained. Carefully
designed work practice steps must be prepared and taught for use
when engineering controls fail. And the best engineering control system
ran be overwhelmed by' poor work practices, even when the engineering
controls are functioning. Moreover, excessive emphasis on engineering
controls may have the effect of appearing to.relieve the individual
employee of responsibility for.effective dust control; while, in the
final analysis, it is our employees who make the entire dust control
program work. We believe that work practices should be elevated to
.1 status and significance at least co-equal with engineering controls.
For these reasons, the asbestos industry recommends a different
treatment of small and intermittent users of asbestos in those provisions of the regulation concerning selection of methods or rompJiancc. This class of employer should be able, within specified limitations, to use personal protection as their primary mode of rompJiancc, provided they are especially careful to train their employees in the need for proper use of that protection.
MEDICAL SURVEILLANCE
.
The OSHA proposal, and .the current regulation as well, if strictly
enforced, would require medical examinations for virtually all
industrial, and a large percentage of all commercial and service
I
employees in the U.S. Since asbestos materials probably are present
in every, or almost every, workplace and may under some conceivable
circumstance release an asbestos fiber or fibers, there will bo
few workplaces where "employees (may not be) exposed to airborne
concentrations of asbestos fibers". It is probable that OSHA did
not intend that medical examinations be given to so many people,
including large numbers of persons whose chances of exposure to harmful
levels of airborne asbestos are nil. Nevertheless, the proposal is very broadly written.
Our survey of the asbestos industry indicates that combined
industrial hygiene and medical costs are the most burdensome portion,
financially, of the entire proposal. Wherever they can be reduced, with
out a negative impact upon the important objectives of the regulation,
they should be so reduced. This will mitigate- the' inflationary impact of the entire asbestos hazard control program and avoid disruption of
report of findings instead of an "opinion", because a doctor's understandable fear of exposure to possible malpractice liability well might distort any opinion which he would be willing to give.
RECORDS RETENTION
..
The retention of certain records generated under the regulation
has obvious value. Retained records have utility, for a limited
period of time, in the diagnosis and treatment of individuals who
may have suffered health impairment as a result of exposure to
airborne asbestos fibers. Retained records may be useful over a longer period of time as a data base for future epidemiological
surveys. But records retention poses some problems.
Storing records for long periods of time entails a cost, though
usually not a large one. It is, however, a considerable adminis
trative burden; and, because it generally is not regarded as of
urgent importance, the problems of storage may be neglected and the
records preserved in a careless or haphazard fashion. OSHA has
proposed that certain records be retained by employers for 40 years
or for 20 years beyond the death or retirement of the employee to
which they apply, whichever period of time may be the longer. It
would not be surprising to find that many of these records, after the
passage of time, are in poor order and in degraded condition. X-rays
in particular, will deteriorate if not properly developed and stored
under appropriate, controlled circumstances. Large'portions of the
files may be in such bad shape as to be of no subsequent use, if left
in the hands of private businesses.
