Question 1 of 27070

According to Pollution Prevention Regulations (33 CFR), the minimum number of bolts permitted in an ANSI standard flange on an oil hose is __________.

🔍 Key Concepts

• 33 CFR Part 154 – especially hose and loading arm requirements for oil transfer operations • ANSI (American National Standards Institute) standard flanges used on oil transfer hoses • Safety margin: why regulators might require a certain minimum number of bolts on a pressurized oil hose connection

💭 Think About

• Which choice seems too low to safely secure a high‑capacity oil transfer hose under pressure and potential movement? • Think about a circular flange: how many bolts are typically needed to keep the load evenly distributed around the gasket so it won’t leak? • In standard industrial piping practice, what is the usual minimum bolt count you see on small ANSI flanges?

✅ Before You Answer

• Look in 33 CFR 154.500–154.540 area for hose and connection requirements and confirm the exact wording on flange bolts. • Verify that the requirement is tied to ANSI standard flanges on oil hoses, not some other type of coupling. • Confirm that the number in the regulation is a minimum, meaning you can always use more bolts, but not fewer.
