LABOR DEPARTMENT SETS FINAL JOB HEALTH RULE ON VINYL CHLORIDE
CHICAGO -- Assistant Secretary of Labor John H. Stender announced today final job health rules that will establish a three-phase program for reducing worker exposflre tb vinyl chloride, a cancer-causing chemical widely used In the manufacture of plastics.
Stender, head of the Department's Occupational Safety and Health Administration (0SHA), said the rule, effective Oct. 4, will ultimately lower exposure to the chemical "to levels that wir protect worker health hy cutting significantly the amornt of vinyl chloride they are exposed to."
In its three-phase progression between Oct. 4, this year and Jan. 1, 1976, the new standard will reduce the 50 parts per million (ppm) in air exposure to vinyl chloride now permitted to as low as one ppm averaged over any eight-hour period and five ppm averaged over any period no longer than 15 minutes.
Vinyl chloride, a gaseous chemical, has been shown to Induce cancer of the liver (angiosarcoma) in workers in tiie United States and other countries.
Its effects first became widely known last January when the B. F. Goodrich Company reported deaths of several of Its employees exposed to the chemical. Exhaustive Investigation and lengthy public hearings followed.
0SHA first held an emergency fact-finding hearing in February, then conducted a survey of vinyl chloride and polyvinyl chloride plants In the South. Meanwhile, more deaths and illnesses were reported.

An emergency temporary rule substantially lowering the exposure levels from 500 ppm
In air to 50 ppm was Issued April 5. Under the Occupational Safety and Health Act of 1970, the emergency standard would
have expired Oct. 5.
Stender told a news conference In Chicago, where he Is attending the National # Safety Congress, that the permanent standard will continue In effect at the 50 ppm level
at the outset.
"We will continue at that level until Dec. 31," Stender said, "to give employers
a reasonable time to accomplish changes'In their plants that will permit them to reduce
exposures or provide employee protective equipment."
He said that on Jan. 1, 1975, employers must reduce levels to one ppm averaged
over any eight-hour period, and five ppm averaged over any period no longer than
15 minutes.
Reduction of exposures to at or below these levels will be made through feasible
engineering and work practice controls. Where these measures will not reduce levels
enough, the rules will permit reductions to the lowest practicable level with employee
respiratory protection provided to meet the one ppm and five ppm exposure limits,
Stender said.
Beginning Jan. 1, 1976 -- the third phase -- wearing of respirators will be
mandatory for workers exposed to levels greater than the one ppm and five ppm allowable
limits. Until that date, wearing of respirators is discretionary for exposures no
greater than 25 ppm.
Plans for reducing exposure to the permissible levels must be available on request
of OSHA.
Before giving details of the new rules, Stender praised the "splendid cooperation"
of the medical and scientific community, labor and industry representatives, and
officials of other government agencies who "provided the Labor Department with a
comprehensive record on which to base its final ruling."

Vinyl chloride, polyvinyl chloride (PVC) and PVC-product manufacturing processes often release vinyl chloride into workplace atomospheres. The new rules will protect workers' health against exposures to significant amounts of vinyl chloride during these processes, Stender said.
The new rules will apply to the manufacture, reaction, packaging, repackaging, transportation, storage, handling or use of vinyl chloride or polyvinyl chloride. They will not apply to the handling or use of products made of polyvinyl chloride.

OTHER KEY PROVISIONS OF THE FINAL VINYL CHLORIDE STANDARD: -- Employers must set up "regulated areas" where concentrations of VCM exceed the
"one and five ppm" limits, with access limited to "authorized" workers.
-- Plans for reducing exposure to the permissible "one and five ppm" levels must be
available on request of OSHA.
-- Direct contact by employees with liquid VCM Is prohibited. -- Monitoring and measuring programs must be initiated to learn whether exposure
levels exceed 0.5 ppm. Depending on levels found, repeat measurements are required at
least monthly or quarterly. They may be discontinued only when two*consecutive
measurements, no fewer than five working days apart, show Individual employee exposures
to be less than 0.5 ppm.
-- Any change In processes that may alter exposure levels will require new
measurements for all affected employees.
Monitoring and measuring methods must meet accuracy requirements ranging from
not less than plus or minus 50 percent In concentrations from 0.25 through 0.5 ppm, to
plus or minus 25 percent for levels greater than one ppm.
-- Where the regular monitoring program shows excursion levels may exceed 25 ppm,
a continuous monitoring and alarm system must be used to alert employees to potential
danger if they are using air filtering respirators (gas masks). At that level, they
must switch to respirators with a clean air supply.
-- Employees and their representatives must be given "reasonable opportunity" to observe monitoring and measuring.
-- Protective garments as well as respiratory protection must be provided for
employees in hazardous situations, such as cleaning operations in PVC vessels.
-- Written plans must be prepared for emergency situations (accidental release of
massive levels) In facilities making or using VCM.
MORE
BOR 007054
-- Employees in VCM or PVC operations must be trained fully on topics such as
the nature of the hazards, protective measures, and the contents of the OSHA rules.
-- Medical programs must Include complete Initial examinations. Subsequent ones
will be required every six months for employees who have worked In VCM or PVC operations
for 10 or more years, and annually for all other exposed workers. Alternative medical
examinations will be acceptable If the examining physician states his procedures and
reasons for substitution. All medical checks are at no cost to employees.
-- Specified signs.or lables are required at entrances to "regulated areas," In-
v hazardous operations or emergency areas, on containers of PVC resin waste, PVC containers and VCM containers.
-- Records of required monitoring and measuring, medical records, and rosters of
TV-*! .,e>l.
->`5 "authorized" workers must be kept for varying specified times, or be sent to the
Director, National Institute for Occupational Safety and Health, If an employer ceases
to do business before the expiration of retention periods.
-- Reports must be made to the nearest OSHA Area Director no later than one month
after establishing a "regulated area, and within 24 hours of any "emergency" exposure.
Also, reports to affected employees must be made within 10 days after monitoring and
measuring shows exposure In excess of the "one and five ppm" limits. Including the

Health Hazards
Vinyl-Chloride Risks Were Known by Many Before First Deaths
Hindsight Shows Weakness In Firms' Systems Aimed At Protecting Workers
The Tip of a Large Iceberg
By Barm* Kiiamhr Stuff Reporter of tup. Wau. sthkbt .'fM-RN u,
A few weeks before Christmas in 1948, Earl Parks, then 29 years old, si,Tried on ns a helper-trainee at the large If. F. Goodrich Co. plastics factory in Louisville, Ky, The plant had been making polyvinyl-chlorkie plastic from vinyl-chloride gas since before the war, using a process developed by Good-, rich in 1937.
1 It was a Trowing Industry that Mr. Parks Joined. Polyvinyl chloride --dubbed PVC for short--had found special, but limited, appli cations in the war years, especially as a fireproof coating for electric wiring In fighter planes and ships. But In the late 1910s, so-called vinyl consumer products, made from PVC, hegan ^coming into vogue; and by the time the 1900s were under way polyvinyl-chloride products such as contain ers, phonograph records and curtains were staples In American households.
The basic Goodrich process, still In use today, pipes vlnyl-chlorlde gas into large re
This is the first of two stories con cerning implications of the discovery that vinyl chloride can cause cancer.
actor vessels; there, the gas Is agitated to gether with a liquid and catalysts. The process causes polymerisation, a linking to. gethcr of the molecules of the gas (a mon
omer) into the long chains that give PVC (a
polymer) Its strength and other desired
characteristics.
The First Years
In his first years with Goodrich, It was Earl Park's Job to crawl inside the reactors after each batch of PVC was drained off and to chip away that portion of the polymer that had congealed. During tho hour-long
task, repeated several times In the course of an eight-hour shift, Mr. Parks and other workers who performed the same function would unavoidably Inhale the heavy, sweet- j smelling fumes of vinyl-chloride gas that
had escaped polymerization.
i
As the 1950s went by and tho 19G0s began,
Earl Parks was working his way up to the |
..Job of foreman, a post that he had attained!
by the time that 111 health forced bis early,
retirement In the late 19G0s. In the years
that ha had worked with Goodrich, the PVC
Industry flourished ns thousands of new uses
were discovered for the polymer.
On Mai ill 3. 1973, at thr age of ,*,n, Earl) Porks died of anglnrari-nmR of the livri, n, type of rnnerr lhat Is invariably fatal. Ills
death attracted eanl puMIr nttcntlon at the
lime, but today the significance of Mr. Park's illness Is unquestionable find shatter ing In ils Implications. For Earl Parks came to he one more .stntlsilc in turning a hypothesis Into n reality: Vinyl chloride van cniiso cancer.
Deadly Statistic*
|
The link between angiosarcoma andi
vinyl chloride Is further buttressed by other
deadly statistics. Seven of Mr. Park's fellow
workers at the Goodrich plant also con tracted the disease, and five have died. In all, there have been 16 documented angio
sarcoma cases In the U.S. In recent years,
all of them linked to vinyl chloride. In addi
tion, 10 other cases havo been reported In!
Europe.
|
While the total number of cases is small,
the Industry lias been shaken to its roots.
The disease now is known to work insidi
ously, slowly, during decades of exposure,' the Implications being that the cases thus-
far are quite likely only the tip of an ice berg. Nine companies, with If plants and 910 employes, currently produce vinyl chlor ide monomer from ethylene, a petrochemi
cal. Tho monomer, in turn, is used by 21 companies operating 36 major plants and employing 5.000 workers, to make more
than five billion pounds of PVC annually. (World-wide production is some 18 billion
pounds annually.) Even the live billion pounds of PVC an
nually produced In this country Isn't enough
to meet the domestic demand for the plastic into which PVC Is formed. Front 3.000 to 4,*
000 processors, employing an estimated 700.000 workers, fabricate the plastic into a wide variety of products ranging from vinyl
floor tiles to shower curtains. According to a
study done for the Society of the plastics In-1
dustry by Arthur D. Little Inc., as many as 2.2 million jobs depend on polyvinyl-chloride plastic. If PVC were banned, the study says, the annual loss to industry in sales and pro
duction would be some $65 billion to $90 bil
lion. (Tat. Manufacturing Chemists Associa
tion estimates the wholesale annual value of i
all PVC products is $3 billion.)
<
Emergency Decree
At the moment, no one believes the in dustry will suddenly come to a screeching halt. However, after the first human cases
of vinyl chloride-induced angiosarcoma were disclosed, the Labor Department's Oc
cupational Safety and Health Administra tion imposed a temporary emergency stan-l dard for PVC factories; thenceforth, OSHA| decreed, the permissible level of vinyl chlor
ide In the air of such factories would be SO parts per million. Tli.it level was far below the Industry standard, in effect for years, of 500 parts per million,
OSt'lA'a emergency decree was made last May. Since then, animal research found that tumors develop at 50'parts per million. Yesterday, OSHA issued a new permanent
standard requiring employers after Jan. 1. 1675, to reduce exposure to one part per mil lion in factory air. averaged over eight hours, and five parts per million averaged over any period no longer than 15 minutes. (See story on page 22.) While considerably
more stringent than the emergency decree, the new permanent standard--particularly with its five-parts-pcr-million provision and
11* allowance of aver clog-nevertheless (nils short of Ihe "no drt<*< '-iL>" 1.mil ad\ocat'd by unions, many med-csl expert! and mu U groups as the .Nall'Jiial Institute for Oc
cupational Sufety and Health, and the American Chemical Society. This no detee.-
able limit would have constant, not average, ndhrrnnco to onc-part-pcr-miltion level.-.-.
Therefore. It seems certain that ihe argu
ment won't nbnte. As the controversy coidlnues. It Is reveal
ing to examine how the link between viryl chloride and cancer w is established. If nothing else, such an examination points out the grave weaknesses of the present system -or lack thcreof-of protecting workers and
others from industrial hazards.
The Judgment Is made In hindsight, but
the history of vinyl chloride shows that evi dence of Its toxicity was often ignored. What's more, the chemical companies knew, hut kept secret for at least six months, the fact that Italian researchers, had shown that rats develop tumors, Includ- j lng angiosarcoma, when exposed to low levels of vinyl cljlorldcjnonomcr. European | companies, which paid lor the animal re search, knew of these research findings for more than a year before tho first human cases were reported hut didn't rcduco tho exposure of their workers to vinyl chloride.
But Dr. Irving J. Sclikoff, an expert on environmental carcinogens, or cancer-caus ing agents, claims that blame shouldn't be
placed at industry's door alone. "We're all a bit responsible," he says. "None of us did our homework." Culpability, he says, should he shared by scientists, government egon-j
clcs and labor unions.
'
The case of Earl Perks Is illustrative. M.. Parks first came to the attention of Goodrich medical people In 1964, when the company, concerned about the known liver toxicity of ethylene dichloride (a chemical from which vinyl chloride Is made) tested the liver function of workers In the Louis
ville plant.
Mr. Parks's readings were abnormal. Nevertheless, he continued to work at the same job. In October 19C1, however, lie was hospitalized with what was initially diag nosed as a bleeding ulcer. Doctors treated the "ulcer" without surgery, and Mr. Parks was released.
He was readmitted to the hospital the fol
lowing May. and the decision was made to operate. But when the operation was begun, surgeons. Instead of finding an ulcer, found instead that Mr. Parks'.* problem resulted
from severe liver damage, which had caused blood to back up in the portal vein leading Into the liver. The surgeons cor rected the vein problem with a shunt and took a sample of liver tissue for analysis.
The analysis showed that the liver had been damaged by exposure to "chemicals." Can cer wasn't mentioned.
(According to testimony at OSHA's hear ings on vinyl chloride, held last June and July, Mr. Parks received a total of almost
$6,000 in workman's compensation from Goodrich before he dicd,_ but only after Goodrich protested that his illness couldn't have resulted from exposure to the chemi cal.)

Dr. Creech says he had been concerned

he heard that .Mr, forks had died, he re

It was In AuguM 1373 that Dr, Creech
leai ned that Mr. Parka had died-the prc-.
vlous March of angiosarcoma of tho liver.
The doctor says he then realized that some
thing was serif sly wrong, sinco another
Goodrich PVC worker, a private patient of
Dr. Creech, had succumbed to tho same,
typo of cancer In 1071. Dr. Creech says he
knew that liver angiosarcoma Is exceedingly j
raro and that two eases among such ,1 small
plant population was abnormal, (In fact,
medical men estimate that fewer than 30
eases occur each year in the U.S., striking
only one In 900,000 persons.)
Dr. Creech met with Goodrich's occupa
tional health director. Dr. Maurice N. John-'
son, who subsequently decided to ask Taber-
shaw-Cooper Associates Inc., a Berkeley,
Calif., epidemiological-studies concern, to
do a survey of Goodrich death records. Cut
the study was hardly needed: on Dec. 19, a
third PVC worker at the Louisville plant
died at the age of S3; ho had been at the
plant for 28 years.
On Jan. 22 of this year, Goodrich officials
met In Washington with officials of the Na
tional Institute for Occupational Safely and
Health and informed them of the three an
giosarcoma deaths. The following day, Ken
tucky occupational-health officials also were
Informed and Goodrich made its first public
announcement.
Almost since Its first commercial Intro
duction. there have been reports that vinyl
chloride is toxic above certain levels. In
deed, during World War II, vinyl chloride
was rejected as a surgical anesthetic be
cause animals developed heart Irritation
when exposed to it. In 1949, Russian scien
tists reported "hepatitis-like changes'' in
the livers of 25% of the workers in a small
PVC plant.
Then, in the late 1950s, research toxocolo-
gists at Dow Chemical Co. showed that ani
mals exposed to as few as 100 parts per mil
lion of vinyl chloride (or 100 molecules of
vinyl chloride in every one million mole
cules of air) developed slight liver damage.
Based on its research, Dow began a pro
gram in the 1360s to reduce tho level of
vinyl chloride monomer in tho air of Its
plants to below 50 parts per million.
Dow published its results in 1961. But the
rest of the industry chose to rely on n Yale
University study that recommended 500
parts per million as a safe level. This same
level had been recommended by the Manu
facturing Chemists Association since 1931,
was affirmed in 1962 by the American Con
ference of Governmental Industrial Hygien
ists and was given the force of law hy OSHA
In 1971. However, evidence at the OSHA
hearings indicates that this level was regu
larly exceeded until this year in many
plants. (The hygienists' group didn't recom
mend lowering the level to 200 parts per
million until 1972, four years after Dow con
cluded from further tests that repeated ex-1
posure by workers to vinyl-chloride mon
omer at an average of 300 parts per million
or above for a working lifetime could cause I
changes In the liver.)
i
During the 19G0S, thcro were reports of a'
disease called acroostcolysls among vinyl-
Lvr; - l r. ui, . t : 1 *.' p _i j
chloride workers. Tho disease consists of slim lesions and changes In tho blood ves sels, leading to degeneration of the hones nt the tips of the fingers and toes in those ex posed to high levels of the monomer. (Emis sions of vinyl chloride are generally lower at plants where the monomer, or gas, Is made, sinco the process is less complex, and there Is less chance for leaks than at the polymerization plants; none of the re ported angiosarcoma cases In this country has occurred among workers making vinylchloride monomer, and only one of the 10 deaths in Europe was in a monomer plant.)
In early 1967, the Manufacturing Chem ists Association arranged with the Univer
sity of Michigan to study acroostcolysls among vinyl-chloride workers, particularly thos# who cleaned tho reactor vessels and others who were exposed to large concentra tions of vinyl chloride In the air. The Michi
gan scientists reported In 1970 that although they couldn't pinpoint vinyl chloride as the cause of the disease, worker exposure lo the monomer should bo cut to 50 parts per milHon or below.
Other than Dow, which had already Insti tuted reductions In air levels of the mon omer, the rest of the Industry In tho U.S. Ig nored the recommendation. Nor was there any significant reaction to findings by Euro pean industry that animals developed ad verse effec ts from vinyl chloride. This was at least partly because the Europeans down
graded the Importance of some of their find ings. For example, Prof. Pier Luigi Viola, a medical director employed In Italy by Sol* vay L Cie., the Belgian chemicals company, found bone changes in rats exposed to air levels of 30,000 parts per million of vinyl .chloride; even more Important, he found that vinyl chloride at that level cauaed ma lignant tumors in the ear canals, lungs and bones of rats.-,
Prof. Viola reported his findings before,
an International cancer congress Jn Houston in 1970. it was the first reported link be tween cancer and vinyl chloride. But the professor expressed doubt about the purity of the vinyl-chloride gss he had used and stated that tho rat cancer findings, because they occurred at such high levels of the monomer, had no human implications,
(Prof. Viola subsequently found tumors In rats exposed to 500 parts per million: but this fact wasn't revealed until well after the first human angiosarcoma cases were re vealed.)
Based on Prof. Viola's early cancer find
ings In Tats, Montedison S.p.A., the huge Italian chemicals company, in 1970 asked Cesare Maltonl, a respected researcher at the Institute of Oncology In Bologna, Italy, to do more extensive animal studes. By Oc tober 1972, Prof. Maltonl says, he had found that 250 parts per million of vinyl chloride produced tumors In rats In three parts of tho body: the ear canals, kidneys and the liver. The liver tumors Included angtosar-
coma. The professor Immediately Informed
his spnji-.ors.
The Europeans offered their Information

to the secrecy condition " he enure, of the
vital Importance of learning of any Indica
tions from the European research , . . with

from duplication of effort."
;
On Jan. 30, 1973, a year before the first
human angiosarcoma cares were reported
by C. F. Goodrich, the MCA finally got the
Maltonl data. For five months, the secrecy
restrictions were such that government
agencies, PVC workers exposed to vinyl
chloride and even company doctors were
kept in the dark. Then, in the late spring,
the Europeans agreed that the chemists' as
sociation conld pass the Information on to'
the U.S. Nationaf Institute for Occupational
.Safely and Health, the Labor Department
agency that monitors worker safety. On
July 17,1973, representatives of the associa
tion and the agency met.
There Is some dispute' as to what tran
spired at the meeting. Tho Labor Depart
ment agency claims It wasn't given the full
story; tho chemists' association claims that
tho agency misunderstood tho findings. But
,one thing Is certain: The agency, and
OSHA, made no move to change the stan
dard of 5i3 parts per million and didn't do
so until after the human angiosarcoma
cases were announced. In Europe, by con
trast, Great Britain had lowered the maxi
mum level to 200 parts per million following
the cases of acroostcolysls In the '60s: and
West Germany had set a level of 100 parts
per'million In 1B70, based on Dow's 1961 re
sults with animals. According to New Scien
tist, tho British science journal, ``No other
section of the U.S. or European industry fol
lowed Dow's lead. The reasons for this In
ternational confusion arc obscure."
This all changed quickly, of course, once
the first human eases of angiosarcoma were
reported by Goodrich. Indeed, the swiftness
with which new research has been carried
out since Jan. 23 Is perhaps without prece
dent in the world Of medicine and science.
Much of this recent research is con
cerned wtlh studies of the incidence of dis
ease of all types among vinyl-chloride work
ers. Thus far. some studies show that work
ers exposed to high levels of vinyl chloride
show greater than expected Incidences not
only ot angiosarcoma but certain other can
cers as well. The ramifications of these find
ings for the future of the industry and its
workers remain to be seen. However, for
the veteran PVC workers, whatever
changes the findings produce will be useless

Sharp Drop in Vinyl Chloride Exposure
Is Ordered by Labor Agency for Workers

ordered :i

trial ,,.IS that haa been linked to liver can
cer.
Tho ruling, which comes alter nine
months of controversy, brought a lawsuit
from the plastics industry, which contends
:tho standard can't be met. and criticism!
I from organised labor, which contends the
jrulo contains loopholes. Vinyl chloride
is a basic ingredient In making many every-
'day plastic products.
/ j The new standard, Issued by the Labor
Department's Occupational Safety and
Health Administration, requires that, start
ing Jan. 1, vinyl chloride levels In tho air
that workers breathe be held to one part
vinyl chloride per million parts of air, aver
aged over an eight-hour period. Actual
levels may exceed one part per million for
short periods, but they must average out to
no more than five parts per million for any
15-minute period within tho eight-hour time
span.
The standard also calls for regular moni
toring of plant air, regular medical exams
for workers and establishment of "regulated
areas" whero vinyl chloride exposure Is
high. It prohibits direct worker contact with
liquefied vinyl chloride and requires posting
of signs warning tho chemical is a "canccr-
suspccl agent."
j Since last April, companies handling
vinyl chloride have been under an enter*
'gency restriction of 50 parts per million,
without any time period.
The emergency standard was issued
alter the discovery, beginning last January,
Of cases of a rare and fatal liver cancer, an
giosarcoma, among workers exposed to
vinyl chloride. Nineteen deaths among such
workers in the U.S. end other countries
have been attributed to liver cancer caused
by long exposure to the chemical.
Vinyl chloride is a gas that Is processed
to form a powdery substance known as poly
vinyl chloride. Polyvinyl chloride, in resm
or pellet form, is then fabricated into a wide
variety of finished plastic products.
Though only about C.500 workers arc em
ployed in plants that make vinyl chloride
and polyvinyl chloride, about 550,000 others,
who work in facilities that create finished
products from the polyvinyl chloride, will
also be covered by the new ruling. Workers
who handle only finished products, and don't
have any chance of contact with "raw"
vinyl chloride or polyvinyl chloride, are the
only ones exempted.
Tho Labor Department initially proposed
{that exposure bo limited to "no detectable
level," without any averaging over time, i
This proposal pleased organized labor and
.some key researchers in the field of occupa
tional health. But tlie Society of the Plastics
Industry, a trade group, and many compa.
Inlcs using tho chemicals, denounced it as
|technologically impossible and warned it
j would drive tho industry out of business. |
In selecting as its final standard one part| per million over eight hours and five parts, per million over 15 minutes, the department apparently was trying to reach a compro>, misc between Its original Idea and the | toughest proposal offered by the industry,: which would have left cx[xisurcs ns high as 10 parts per million in some plants and 25 parts per million in others.
The department sought to smooth further, the adjustment for Industry by delaying! until next January the drop from the pres*:
j ent 50 parts per million. Also, it gave its en*:
Iforccmcnt staff discretion to determine how 'the companies must meet the standard.
While the goal is to reacli the new levels)
through "engineering and work practice' controls," such controls must be deemed "feasible," and companies can deal with any exposures produced by Inadequate con trols by giving workers respirators..
A date wasn't set in the ruling for Im proving plant engineering and practices to Hie point where respirators won't be needed. What's more, until January 1976 workers ' may refuse to wear the respirators when ex posures don't exceed 5 parts per million, even if they exceed the one part per million
/cr eight hours specified in the regulation. ' Despite this attempt at compromise, however, the Society of tho Plastics Indus try and some producers sued the Labor De
partment to overturn the ruling only mo ments after it was issued yesterday. And' Firestone Plastic Co., a unit of Firestone | | Tire & Rubber Co., said It will ask a court to! stay enforcement of the standard while the suits are being tried.
Ralph Harding, president of the industry group, said the standard is "unrealistic, probably will be Impossible for most, if not all, of the Industry to meet and appears to have been developed on some basis inconsis- j tent with recorded tacts." The job-safety agency "may believe that it has adopted a compromise position," but the result is un acceptable to the Industry, he added.
Industry sources also indicated displea sure at the inclusion of plants making fabri cated products from polyvinyl chloride. Tho industry had proposed excluding these plants, contending they didn't, present any hazard.
(Page 22)
But the department said it decided to In clude them because polyvinyl chcride resin and pellet.-; can give off vinyl chloride gas in small amounts during procc: sing. It said, however, if the plants weren't exposing workers to more than half a part per milker, of vinyl chloride gas, they needn't under take any control measures.
In Midland, Mich.. Dow Chemical Co said the standard;; were "unnccessarih stringent" and unsuppoilcd hy the data o.-i Dow workers that was presented at public hearings.
Organized labor expressed some immedi ate reservations of its own.
In Akron, OfciO, Pfilcr Bommarito, presi-, dent of the United Rubber Workers union. |
which represents many vinyl chloride work- j
ers, said "It would appear this thing has a I number of loopholes in it." Mr. Eommanto reserved final judgment until he has seen a full text of the regulations, but he was quick to take Issue with the decision to let workers decline the use of a respirator until 1576. "We can't make a guy put on a respirator, and while he's not wearing one; he may be endangering himself." What is more, he added. "The respirator situation Is going to be even worse in nonunion plants."
The department defended its reliance on the use of respirators, saving detinue dates couldn't be set for dealing with the problem solely through engineering and work rules because "we are presently unable to deter mine when It will be feasible," It added. "We would agree that resp;m-.',rs ;*-e many drawbacks" but said, in the at.-en.1 of complete engineering control, they arc needed.
The official explanation of the rcguln-, tions also said that although a deadline wasn't set for completing engineering and work-rule changes, a continuing plan, avail able for government inspection, must be pursued by each company at a pace agreed on by safety inspectors, until respirators arc needed only occasionally.
