🔍 Key Concepts

• 46 CFR requirements for inspection of boilers • Authority and discretion of a marine inspector when safety may be affected • Purpose of drilling or gaging: determining actual metal thickness for safety evaluation

💭 Think About

• Which choice gives the inspector the broadest authority to act when there might be a safety issue? • Does the regulation limit thickness checks only to specific events (like first inspection or a fixed percentage loss), or does it focus on safety concerns in general? • Would regulations be written to prevent nondestructive testing, or to allow the inspector flexibility to choose appropriate methods?

✅ Before You Answer

• Confirm in 46 CFR whether the inspector’s authority is tied to a specific inspection interval or to safety concerns about the boiler • Check if there is any mention of a specific percentage loss of thickness triggering drilling or gaging • Verify whether the regulation talks about excluding nondestructive testing methods, or instead emphasizes ensuring the boiler is safe for service
