Hydrazine can also be used for corrosion control in boilers and hot-water heating systems. It is the starting material for many derivatives, like foaming agents for plastics, antioxidants, fungicides, herbicides, and pharmaceuticals. Hydrazine is also used in photograph development techniques.

According to the U.S. Environmental Protection Agency, “Symptoms of acute (short-term) exposure to high levels of hydrazine may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, and coma in humans.  Acute exposure can also damage the liver, kidneys, and central nervous system in humans.  The liquid is corrosive and may produce dermatitis from skin contact in humans and animals.  Effects to the lungs, liver, spleen, and thyroid have been reported in animals chronically (long-term) exposed to hydrazine via inhalation.  EPA has classified hydrazine as a Group B2, probable human carcinogen [cause of cancer]."
