In certain workplaces, there are products or devices that can cause malformations or miscarriages. The most important sources of danger are chemicals, solvents, gases, metals, and radiation. If you have any concerns, consult your health care provider. It is up to you to inquire about the risks at your job.
You can also get information from your health and safety committee at work. If there is no committee in your workplace, this may be a good time to organize one with your colleagues.
