Reproductive Hazards Management Guidelines
Adopted April 2011
Encourages persons responsible for workplace
health and safety to:
• Assess their workplaces for potential reproductive
hazards
• Implement practices including: communication about
potential risks and hazards, temporary reassignment,
hazard elimination, and exposure control.
Reproductive Toxicity
Adverse effects on the reproductive system that may
result from exposure to toxins or environmental
agents.
Includes alterations to the reproductive organs and/or
the related endocrine system
Developmental Toxicity
Adverse effects on the developing organism that may
result from exposure before conception (either
parent), during prenatal development, or post-natal
to the time of sexual maturation
Includes fetal death, structural abnormalities or birth
defects, functional deficiencies, or altered growth

1918 3 million 1918 nearly 3 million new
women workers were employed in food, textile
and war industries.
WW 2 Women in Industrial Jobs
◦ 310,000 US aircraft industry (from 1 to 65%)
◦ By 1945 One of 4 married women worked outside the
home
Number of women in the workplace increased
from 30 million in 1970 to more than 67
million in 2007
Policies that attempt to protect the fetus from
workplace hazards by excluding fertile women
from certain jobs
Common in the United States in the 1970s and
1980s
Became controversial because women were being
excluded from certain jobs (including promotional
opportunities and better wages/benefits) on the
basis that they could become pregnant, even if they
had no intention of doing so
Men were not included in the policies even when
their reproductive health could also be impacted by
exposure
1982, battery manufacturer Johnson Controls
implements a fetal protection policy preventing
women capable of bearing children from holding
jobs with lead exposure
Class action lawsuit raised against Johnson
Controls by women alleging lost jobs or transfers
to lower paying jobs as a result of the policy
1991, U.S. Supreme Court ruled that Johnson
Controls' fetal protection policy discriminated
against women in violation of Title VII of the 1964
Civil Rights Act as amended by the Pregnancy
Discrimination Act (PDA)
Forbids sex discrimination in employment
“It shall be an unlawful employment practice for an
employer
◦ (1) to fail or refuse to hire or to discharge any individual, or
otherwise to discriminate against any individual with respect
to his compensation, terms, conditions, or privileges of
employment, because of such individual’s race, color, religion,
sex, or national origin; or
◦ (2) to limit, segregate, or classify his employees or applicants
for employment in any way which would deprive or tend
to deprive any individual of employment
opportunities or otherwise adversely affect his status as an
employee, because of such individual’s race, color, religion,
sex, or national origin.”
Amends Title VII of the Civil Rights Act of
1964 to prohibit sex discrimination on the
basis of pregnancy
◦ “The terms 'because of sex' or 'on the basis of sex'
include, but are not limited to, because of or on the
basis of pregnancy, childbirth, or related medical
conditions; and women affected by pregnancy,
childbirth, or related medical conditions shall be
treated the same for all employment-related purposes,
including receipt of benefits under fringe benefit
programs, as other persons not so affected but similar
in their ability or inability to work, and nothing in
section 703(h) of this title shall be interpreted to
permit otherwise.”
Implications of the U.S. Supreme Court ruling:
◦ Employers can’t deny fertile women a choice given to
fertile men as to whether they wish to risk their
reproductive health for a particular job.
◦ An employer can't determine if a work environment is too
hazardous for a pregnant worker and change her work
status solely on the basis of her pregnancy. The pregnant
employee and her physician are charged with making such
a decision.
◦ Fetal protection policies are not legal even if the employer
can prove that a substance to which its workers are
exposed will endanger the health of a fetus. If a company
complies with health and safety regulations and fully
informs the woman of the risk, then the employer has not
been negligent.
Employers, concerned with both fetal health
and the specter of massive tort liability for
injured third parties.
Caught in a legal crossfire:
Do nothing about these issues and be sued
by injured parties
Utilize a FPP and be sued by workers denied
their equal employment rights.
Avoid or significantly modify FPP
Rely on improving overall conditions in work
environment
Substitute identified substances where feasible ex.
Lead
Ethylene Glycol Monomethyl ether & acetate
Ethylene Glycol Monoethyl ether & acetate
Hazard Communication both genders
Provide MSDS’s and PPE to Pregnant workers for
review with OB, and allow work restrictions as
requested.
1996 NIOSH formed a National Occupational
Research Agenda (NORA) including RHRT to:
Promote communication and partnering
among reproductive toxicologists, clinicians
and epidemiologists
Improve reproductive hazard exposure
assessment and management
Encourage needed research.
"While more than 1,000 workplace chemicals
have shown reproductive effects in animals, most
have not been studied in humans. In addition,
most of the 4 million other chemical mixtures in
commercial use remain untested. Physical and
biological agents in the workplace that may affect
fertility and pregnancy outcomes are practically
unstudied. The inadequacy of current knowledge
coupled with the ever-growing variety of
workplace exposures pose a potentially serious
public health problem. “
Prioritized reproductive toxicants for further
Research and helped coordinate the studies
Promoted occupational exposure assessment in
surveillance studies

“The message that reproductive health includes both men and
women, and that it can be affected by their workplace
exposures, needs to reach the workers and their employers
through MSDS communication”

REPRODUCTIVE HEALTH PROTECTION PROGRAM
Summary
This program provides assistance to staff, and supervisors when dealing with questions related to reproductive
health and work at the University. These guidelines provide the necessary information and direction to assist the
concerned persons and their supervisors so that options are understood and and informed decision can be
made by the employee. These guidelines are developed to provide additional protection for the fetus, and to
establish specific procedures to protect pregnant employees. Control of employee exposures will be carried out
without economic penalty or loss of job opportunity, including, if necessary, consideration for work assignment
changes, consistent with University personnel policy. Assuring protection from exposures to reproductive
hazards requires full cooperation with these procedures as soon as pregnancy is contemplated or determined to
implement these guidelines.
Background
Through the course of work at NC State University, employees may work with agents which are known or suspect to
be hazardous to human reproduction. These agents include radiation, chemicals, biological agents, and physical
hazards, as well as many other factors (standing, climbing, heat/cold exposure, medications, etc). Since risk
factors are encountered both in work and at home, a review by the concerned employee’s personal physician is
recommended so that a complete picture can be obtained. Consultation is also available through the
Environmental Health and Safety Center and NC consulting physicians associated with the University
occupational medicine program.
Definitions
When one considers reproductive risk, both reproductive toxicity and developmental toxicity should be considered.
Reproductive Toxicity – Adverse effect on the health of the reproductive organs, endocrine system, or gametes (egg
or sperm) from exposure to an exogenous agent. May result in effects such as mentstrual dysfunction, impaired
fertility, feminization, masculinization, or inability to maintain a pregnancy.
Developmental Toxicity – Adverse effects on the developing organism that may occur anytime from conception to
sexual maturity. Effects may include spontaneous abortion, structural or functional defects, low birth weight, or
effects that may appear later in life.
Persons, both male and female, who are sexually active, planning a pregnancy, or pregnant should recognize the
need for safe work practices at all times, since certain reproductive effects occur at very early stages of
pregnancy, perhaps prior to recognition by females that they are pregnant.
Objective
To educate staff on the risks to reproductive health associated with work related activities and the need for safe
work practices on a continual basis.
To provide procedures for assessing workplace condition, obtaining medical input, and assessing options for
managing work and reproductive risk.

Introduction
On September 7, 2012 XXX, LLC at the request of XXX provided reproductive health consultation and performed a
fetal protection review of work tasks associated with a laboratory researcher’s assigned responsibilities at their XXX,
MO site. The purpose of the visit was to make available and review selected reproductive health references and review
and examine materials, equipment and work practices with a researcher currently in her first trimester of pregnancy.
Job description
The employee interviewed is a Researcher in the XXX Department assigned to tasks performed for quality assurance
and method development. Work is performed in Labs XXX, XXX, XXX, Prep Area and the Sample Login Room. Work
tasks include grinding dry product and raw material, weighing and transferring dry chemical materials, and
transferring and handling liquid chemical materials and prepared mixed solutions. An ultrasonic sonicator located on
a bench top approximately 6 feet from her work station is infrequently used for sample preparation. She is scheduled
to begin a new method development assignment soon that includes grinding and performing lab procedures with raw
chicken and swine flesh, fat and organs. Material lifting of up to 25 pounds is common. Work involves approximately
50% of time spent sitting at computer and Video Display Terminal (VDT).
Controls
Safe operating procedures for identified chemical materials require transfer and handling inside laboratory hoods,
however many of the chemical materials used are handled on laboratory bench tops. Lab grade latex or nitrile gloves
and safety glasses or goggles are used for all laboratory tasks. A filtering face piece dust respirator is used when
grinding dry materials. Installation of an enclosure equipped with local exhaust ventilation is being evaluated in the
Prep Area where dry material grinding is. Raw animal tissue grinding is performed in a ventilated lab hood labeled
with biohazard warning signs. The spill response plan limits the cleanup by the researcher to small quantity releases.
In the case of a large spill, the lab is evacuated and Emergency Response Team mobilized.
Reproductive Health Consultation
NIOSH Publication 99-104 “The Effects of Workplace Hazards on Female Reproductive Health” was used to guide a
general discussion of related workplace hazards, preventative measures and precautions. A copy of the document
was provided to the lab researcher. Research and guidance documents from OSHA, EPA, National
