The growing concern over the health of the working woman
by Gale A. Ressler
Are women of child-bearing age
endangered by exposure to toxic in dustrial substances? More and more medical scientists are answering "Yes" to that question; researchers are discovering that many of the substances found in the workplace -- lead compounds, vinyl chloride, anesthetics -- are either teratogens or mutagens, substances that can cause abnormalities in offspring.
In light of this recent scientific assessment, many working women of child-bearing age, exposed to teratogens or mutagens, are con fronted with a set of thorny ques tions: Must they quit their job? De mand to work in a safer plant area? Not have children?
And the safety and occupational health professional is left to ponder the complex ramifications of the re cent scientific disclosures:
If he removes these women workers from the job, the company may be beset by litigation under dis crimination laws.
If he leaves them on the job, the company may be subjected to costly occupational disease claims.
If he recommends removing the substance or converting to a closed system, he may be raising mighty questions of economic and techno logical feasibility.
If he transfers women workers to other jobs at no loss of pay, he may be opening the plant's door to delegations of other workers who seek the same arrangement for dif ferent reasons.
Issues dealing with the occupa tional health of women of child bearing age surfaced when scien tists discovered that molecules of most substances, with the excep tion of large molecules or those with high electrical charges, can cross the placenta by simple diffusion.
Therefore, many chemicals enter ing the pregnant worker by inges tion, skin absorption, or inhalation potentially can harm the fetus. Sci entists presently do not know, how ever, what exact concentration of a teratogenic or mutagenic agent the embryo or fetus can tolerate before damage occurs.
General public awareness of women's health hazards, which has been building gradually, got further impetus last spring with the publica tion of a study conducted by the U.S. Department of Health, Educa tion and Welfare at Firestone Tire and Rubber Co., Pottstown, Pa. HEW researchers found that the wives of a sampling of workers who came into contact with vinyl chloride had twice as many miscar riages and still births as the wives of workers who did not handle the substance.
Andrea Hricko, health coor dinator at the Center for Labor Re search and Education (University of California), in her book. Working For Your Life: A Woman's Guide to Job Health Hazards, tells of a worker employed in the plastics in dustry who had just been recalled after a lay-off: "Upon her return to a plastics factory, she was informed that she could no longer work in the vinyl chloride operation because it might be hazardous if she became pregnant. The company informed her that she could only return to work if she had a note from her doc tor, saying that she was no longer able to bear children ..."
Mercury, lead, and others
Mercury also can harm a develop ing fetus. The substance quickly vaporizes into the air, and thus is readily inhaled. As a metal, it is

setting a special radiation standard to cover fertile women. However, NRC's legal advisors deemed both proposals infeasible -- the first, they counselled, would be an inva sion of privacy, and the second, un constitutional sex discrimination. After considering other alternatives such as setting a stricter standard, the NRC's Office of Standards De velopment published' Regulatory Guide 8.13, "Instruction Concern ing Prenatal Radiation Exposure." which offers the^nrecnant worker
the following alternatives: "(1) If you are now pregnant or
expect to be soon, you could decide not to accept or continue assign
ments in these areas. "(b) You could reduce your ex
posure, where possible, by decreas ing the amount of time you spend in the radiation area, increasing your distance from the radiation source, and using shielding.
"(c) If you do become pregnant, you could ask your employer to reassign you to areas involving less exposure to radiation. If this is not possible, you might consider leav ing your job. If you .decide to take such steps, do so without delay. The unborn child is most.sensitive to radiation during the first three months of your pregnancy.
"(d) You could delay having chil dren until you are no longer working

0.5 rcm. "You may also, of course,
choose to: (e) Continue working in the
higher radiation areas, but with full
awareness that you are doing so at some small increased risk for your
unborn child ..."
Leaders of the women's libera
tion movement have been strangely
silent regarding exposure of women of child-bearing age to industrial substances. If, as appears likely, they break their silence soon, public sensitivity to this issue will heighten. What recourse is being sought under Title VII is difficult to measure. EEOC statistics for 1974-75 indicate approximately 29,000 women filed lawsuits based on discrimination charges, but that covers the entire spectrum of com plaints.
Picking up the gamut?
In the future, occupational dis ease claims would seem to be a dis tinct possibility. As NIOSH's Dr. Finklea puts it: "The only redress of the damaged child would be civil action."
Against this background, safety and health professionals looking to the classic solution encounter these complexities:
Reducing exposure to toxic substances through engineering controls may cut down on claims, though, in some cases, they may not be technologically or econoTnicairy feasible.
Providing protective clothing and equipment to reduce exposure, but aware, in so doing, that OSHA regards such protection only as an "interim" solution.

In a recent policy dictum, the
United Auto Workers (UAW), of-
ten a bellwether union, opposed
mandatory transfer as a means of
abating over-exposure to lead.
UAW policy states:
"Coerced transfers for this rea-
son will be considered sex discrimi-
nation in violation of collective bar-
gaining agreements' nondiscrimina-
tion clauses and federal law."
However, the policy further states
that agreements need to be made
with employers at local and national
levels, insuring that "workers who
choose to transfer from lead-
exposed jobs should receive full
protection of wages, classifications,
fringe benefits, seniority, promo-
tions, and other contractual rights.
Privacy as to the reasons for trans-
fer must be absolutely protected.
These transfers should be consid-
ered identical to other medical re-
strictions."
Whichever approach you choose,
you're likely to find that the issue of
women of child-bearing age in the
workplace resists easy solutions.
Nonetheless, solutions must be de
vised lest excessive exposure to
toxic substances takes its toll on the
next generation.
