🔍 Key Concepts

• Acetylene properties under pressure • The role of acetone inside acetylene cylinders • What hazard occurs when acetylene pressure is too high in a welding system

💭 Think About

• Think about what happens to acetylene itself when its pressure exceeds recommended limits, not just what happens at the torch tip. • Which of the choices describes a danger that exists even if the torch is not lit or in use? • Which answer is about the gas becoming unstable in the system, rather than a problem with torch operation or the acetone?

✅ Before You Answer

• Confirm that acetylene becomes unstable above a certain pressure even without a flame present. • Distinguish between torch-related malfunctions (problems at the flame/torch) and system-wide hazards (in the hose or cylinder). • Verify that acetone is used as a stabilizer/solvent for acetylene, and consider whether the main pressure limit is to protect the acetone or the acetylene itself.
