The last 1.0 meter (3.3 feet) of vapor...

🔍 Key Concepts

• 33 CFR Part 154 – Facilities Transferring Oil or Hazardous Material in Bulk (vapor control and piping identification requirements) • Color coding for vapor piping vs. liquid cargo piping near the vessel connection • The specific requirement for the last 1 meter (3.3 feet) of vapor piping before the vessel vapor connection

💭 Think About

• Which regulation in 33 CFR covers how vapor piping must be marked and color coded for loading/unloading operations? • Think about how the color pattern for vapor lines is made distinct from typical cargo or fuel lines so it can’t be confused in low visibility or under stress. • How might a striped pattern help operators visually confirm they are connecting the correct vapor line right at the ship/shore interface?

✅ Before You Answer

• Verify in 33 CFR Part 154, Subpart E (or applicable vapor control section) what exact color pattern is specified for vapor piping near the vessel connection. • Confirm that the requirement specifically applies to the last 1.0 meter (3.3 feet) before the vessel vapor connection, not the entire run of vapor piping. • Make sure you distinguish between markings required for vapor lines and any different markings that may apply to cargo or product lines so you don’t mix them up.
