Question 1 of 27070

If a mobile offshore drilling unit has four hand portable fire extinguishers that can be recharged by personnel on the unit, how many spare charges must be carried?

🔍 Key Concepts

• Requirements for spare charges for hand-portable extinguishers on mobile offshore drilling units (MODUs) in 46 CFR • Whether the regulation sets a fixed number of spares or a ratio based on how many extinguishers can be recharged on board • Difference between units that can recharge extinguishers on board vs. those that cannot

💭 Think About

• Look up the specific 46 CFR section that covers fire protection on MODUs and find the table or paragraph that mentions spare charges for hand-portable extinguishers • Ask yourself: when recharging is possible on board, does the rule require one spare for each extinguisher, or a lesser amount? • Compare the required spare charges if you had, for example, 2 extinguishers vs. 4 extinguishers to see if there is a pattern or minimum requirement

✅ Before You Answer

• Verify the exact CFR citation for MODU fire extinguisher requirements (part and section) • Confirm the words about spare charges, especially any wording like "at least", "for every X extinguishers", or "not less than" • Make sure you are reading the line for hand-portable extinguishers that are rechargeable on board, not fixed systems or non-rechargeable types
