Which PPE level is required when testing hydrazine leaks?

• A. No PPE required
• B. Standard work uniform
• C. Full MOP gear
• D. Respirator only

Answer: (C)

When testing hydrazine leaks, the hazard includes both inhalation of toxic vapors and dermal/eye exposure from splashes, so you need comprehensive protection. The full MOP gear provides the complete barrier: a chemical-protective suit with gloves and boots plus a respirator, covering both skin and respiratory routes and guarding against liquid splashes and vapors. That level of protection is necessary to safely approach and evaluate a leak risk. Other options fall short because they don’t address all exposure routes. No PPE is unsafe given the toxicity. A standard work uniform lacks chemical resistance and splash protection. A respirator alone protects inhalation but leaves skin vulnerable to splash and liquid contact, so it isn’t sufficient for hydrazine leaks.
