What PPE is recommended when handling hydrazine/ monopropellant?

• A. Full PPE and SCBA.
• B. No PPE required.
• C. Only gloves.
• D. Only eye protection.

Answer: (A)

Handling hydrazine/monopropellant requires protection against skin contact, eye injury, and inhalation of toxic vapors. This chemical is highly toxic, corrosive, and volatile, so you need a barrier that covers skin and eyes and a way to breathe clean air. Wearing full chemical protective clothing with chemical-resistant gloves, eye protection or a face shield, and boots, plus a self-contained breathing apparatus, ensures you’re protected from splashes and from inhaling hazardous vapors. The aim is to block all exposure routes, not just one part of the body, because even small exposure can cause serious health effects.

Choosing only gloves or only eye protection leaves critical routes exposed, and skipping PPE altogether is unsafe.
