🔍 Key Concepts

• Purpose of insulating flanges in preventing stray currents and arcs between ship and shore during cargo transfer, especially on tank vessels • Recommended testing and maintenance practices for safety-related fittings on cargo transfer systems • Why cathodic protection systems and insulating flanges are NOT interchangeable safety measures

💭 Think About

• Ask yourself: What is the basic safety function of an insulating flange during loading/unloading, and which option actually supports that function? • Consider which options, if followed in real life, could increase the risk of ignition or static discharge during cargo transfer. • Think about whether turning off a system (like cathodic protection) gives the same physical separation and insulation that a flange provides.

✅ Before You Answer

• Verify which choice reflects a routine inspection/testing practice you would expect for any critical safety device on a cargo transfer system. • Eliminate any options that would reduce safety controls during cargo operations (e.g., allowing more hot-work or accepting lower insulation performance). • Check whether any answer is suggesting that one safety system can be substituted for another when they actually serve different purposes.

Question 1 of 20

Which statement is TRUE concerning insulating flanges?

After the insulating flange is installed, hot-work may be performed on deck.

The measured resistance value after installation should be less than 1,000 ohms.

Switching off a cathodic protection system may be substituted for using an insulating flange.

They should be inspected and tested periodically to ensure that the insulation is clean and in good condition.
