A Reproductive Hazard sign tells you that substances or conditions in a place can create danger for health. This danger can bring risk to fertility, pregnancy results or a baby's growth

Lead, mercury, certain organic solvents, pesticides, ionizing radiation some pharmaceutical compounds, carbon monoxide and many other chemicals that have proven effects on health. Some substances affect fertility, others risk a baby that is still developing during pregnancy. The SDS for each chemical shows whether reproductive toxicity is a documented concern.

In places where substances with known reproductive toxicity are used or kept, in labs that work with embryo-toxic chemicals, in areas that control radiation, in places where lead or mercury danger is possible and anywhere a hazard review says reproductive health matters for workers of childbearing age or beyond.

OSHA 29 CFR 1910.1200 under the Hazard Communication Standard says Reproductive Toxicity must be shown with labels and SDS. Osha substance‑specific rules, like 29 CFR 1910.1025 for lead and 29 CFR 1910.1096 for ionizing radiation give special rules about Reproductive Hazards. OSHA 29 CFR 1910.145 deals with accident‑prevention signs and tags.

That decision must involve the worker, the employer, and a doctor. The Reproductive Hazard sign shows the danger. How to handle that danger for a worker- whether to move the worker, add more controls, or change duties- needs a separate talk between the people involved. Employers also have duties under the Pregnancy Discrimination Act when making those decisions.

No. Reproductive Hazards can affect fertility too. Some substances also change hormone health for both men and women. The Reproductive Hazard sign tells everyone in the area about the danger, not only people who are pregnant or planning a pregnancy.
