8.7 Reproductive Toxins
The OSHA Lab Standard defines a reproductive toxin as a chemical “which affects the
reproductive capabilities including chromosomal damage (mutations) and effects on fetuses
(teratogenesis).”
A number of reproductive toxins are chronic toxins that cause damage after repeated or long
duration exposures and can have long latency periods. Women of childbearing potential should
be especially careful when handling reproductive toxins. Pregnant women and women intending
to become pregnant, or men seeking to have children, should seek the advice of their physician
before working with known or suspected reproductive toxins.
It is important to be aware of the threats to reproductive health and prevent potential
reproductive hazard exposures for male and female employees and students who work with
known and suspected reproductive toxins including chemical, biological, radiological, and
physical agents. Your EHSO is available to respond to concerns or questions on reproductive
hazards, conduct workplace hazard assessments, and provide recommendations to address or
eliminate specific reproductive risks. As with any particularly hazardous substance, work
involving the use of reproductive toxins should adhere to the Guidelines for Working with
Particularly Hazardous Substances.
More information on reproductive toxins can be found on the OSHA Safety and Health Topics
for Reproductive Hazards webpage. The State of California has developed an extensive list of
“Reproductive Toxins Known to the State of California through Prop 65”. Please note, this list is
being provided as supplemental information to the OSHA, NTP and IARC chemical lists and is
not legally mandated by New York State.
8.8 Acute Toxins
OSHA defines a chemical as being highly toxic if it falls within any of the following categories:
(a)
(b)
(c)
A chemical that has a median lethal dose (LD50) of 50 milligrams or less per
kilogram of body weight when administered orally to albino rats weighing between
200 and 300 grams each.
A chemical that has a median lethal dose (LD50) of 200 milligrams or less per
kilogram of body weight when administered by continuous contact for 24 hours (or
less if death occurs within 24 hours) with the bare skin of albino rabbits weighing
between two and three kilograms each.
A chemical that has a median lethal concentration (LC50) in air of 200 parts per
million by volume or less of gas or vapor, or 2 milligrams per liter or less of mist,
fume, or dust, when administered by continuous inhalation for one hour (or less if
