Q

Combustion can occur inside a piping system such as a vapor collection header in a marine emission control system. Which of the following will not aid in this combustion process?

🔍 Key Concepts

• Fire triangle (fuel, oxygen, heat/ignition) in confined spaces and piping • Role of inert gases in preventing or suppressing combustion • Conditions required for vapor combustion in marine emission control systems

💭 Think About

• Think about what three basic elements must all be present for any fire or combustion to continue. • Look at each choice and decide whether it adds one of those elements, or removes/blocks one of them. • In vapor collection headers, what kind of gas is sometimes used to make the atmosphere too lean to burn?

✅ Before You Answer

• Identify which option is commonly used as an inert gas to prevent or suppress fires. • Confirm which items are required parts of the fire triangle (fuel, oxygen, ignition source). • Ask: which choice would actually reduce or prevent combustion rather than support it?
