Question

List, in proper order, the six steps to be followed when you are shutting down in oxy-acetylene welding station?

Answer 1

To shut down an oxy-acetylene welding station, close the gas valves on the torch and cylinders, then bleed out the gas from the hoses until pressure gauges read zero, and finally close the torch valves.

Step-by-step explanation:

To shut down an oxy-acetylene welding station safely, you must follow specific steps to ensure that both the equipment and the operator are not at risk. Here is the proper order:

1. Close the acetylene valve on the torch to stop the flow of gas.
2. Close the oxygen valve on the torch, which will completely extinguish the flame.
3. Turn off the acetylene cylinder by closing the tank valve to ensure no more gas can flow into the lines.
4. Turn off the oxygen cylinder valve to cease all oxygen flow.
5. Bleed out the remaining gas in the hoses by opening the torch valves until the pressure gauges read zero.
6. Once all pressure is released and gauges read zero, close both torch valves to prevent any contaminants from entering the system.

These steps ensure that the gas supply is securely shut off and that all gas is vented from the hoses, preventing potential hazards such as a flash back or gas leak when the station is not in use.
