🔍 Key Concepts

• Safe shutdown sequence for oxyacetylene systems (what gets closed first, what gets bled off) • Purpose of bleeding pressure from hoses and regulators before long-term storage • Risks of leaving residual pressure or only closing valves at one end of the system

💭 Think About

• Think through the full path of the gas system: cylinders → regulators → hoses → torch. For long-term securing, which points need to be isolated and which need to be depressurized? • Consider what could happen if gas is left under pressure in the hoses for an extended period. How could leaks, heat, or hose damage affect safety? • Ask yourself: for maximum safety, do we want any pressure trapped in the system, or should the system sit with no pressure when stored?

✅ Before You Answer

• Verify which valves provide primary shutoff at the source of the gas supply • Check whether hoses and regulators should remain under pressure during extended shutdown • Confirm that the procedure includes both closing at the cylinders and dealing with remaining pressure in the system before closing the torch valves
