Question 1326 Deck General

The correct answer is D) red/yellow/red. The last 1.0 meter (3.3 feet) of vapor piping before the vessel vapor connection must be painted in the international color scheme of red/yellow/red. This color scheme is specified in the regulations to provide a clear visual indication of the hazardous nature of the vapor piping. The other answer choices, while potentially used for other purposes, do not meet the specific regulatory requirement for the color scheme of this critical section of the vapor piping.
