🔍 Key Concepts

• Fixed and portable CO₂ system inspection intervals under 46 CFR for mobile offshore drilling units (MODUs) • Difference between visual inspection, weighing or measuring contents, and hydrostatic testing frequencies • How often CO₂ extinguishers can lose charge and why regulations require regular weight checks

💭 Think About

• Ask yourself: does CO₂ slowly leak over time, and would that require more frequent or less frequent weighing? • Think about which interval (monthly, quarterly, semiannually, annually) is most commonly used in regulations for checking the charge condition of portable extinguishers. • Consider that hydrostatic tests are done in years, but charge and condition checks are done in shorter intervals. Which option best fits a routine charge verification?

✅ Before You Answer

• Verify the required interval for portable fire extinguisher inspections on MODUs in 46 CFR (Subchapter I-A, MODUs). • Confirm which maintenance task specifically involves weighing CO₂ extinguishers versus just doing a visual examination. • Make sure you are not confusing the interval for hydrostatic pressure tests (in years) with the shorter interval for operational/condition checks (in months).
