What additional precautions should be taken when making temporary repairs to a MODU that is operating when hydrogen sulfide is present?

🔍 Key Concepts

• Hydrogen sulfide (H₂S) hazards on offshore units (toxic inhalation risk, not just fire/explosion) • How temporary repairs on a MODU (Mobile Offshore Drilling Unit) might expose personnel to gases • Regulatory focus on personal protective equipment (PPE) and atmospheric monitoring in H₂S environments

💭 Think About

• Which option directly protects crew from breathing in H₂S during repair work? • Do any of the options seem unrelated to gas inhalation hazards and more about general operations or storage? • If H₂S is present, what kind of continuous safety check is normally required in the work area?

✅ Before You Answer

• Verify which choice mentions respiratory protection (SCBA, air-line respirators, etc.). • Check which option includes monitoring of the atmosphere for H₂S concentration. • Ask yourself whether removing bulk materials from P-tanks or sealing ventilation would by itself protect workers from toxic gas exposure at the repair site.
