Oxy-Acetylene Cutting Quiz

What are some safety features to consider when using oxy-acetylene cutting?

• Using petroleum products around the edges

• Covering the oxygen with a fuel source

• Opening the oxygen tank with a quick burst

• Rupturing the diaphragm in the regulator

How should the pressure adjustment knob be set on the oxygen regulator?

• Completely tightened

• Relatively loose

• Backed off completely

• Adjusted to the maximum pressure

Why should the t-handle on the oxygen regulator be pointed away from the face and body?

• To prevent the regulator from getting pregnant

• To avoid accidentally hooking it up backwards

• To prevent the t-handle from shooting out

• To ensure proper pressure adjustment

What type of threads are present on the acetylene tank and regulator?

• Right-handed threads

• Left-handed threads

• Interchangeable threads

• No threads

Why should the acetylene fuel line be opened only one to one and a half turns?

• To prevent damage to the threads

• To ensure proper fuel flow

• To easily shut off the fuel source in case of fire

• To avoid leaks in the system

What is the recommended working pressure for oxygen when cutting eighth inch thick material?

• 15 psi

• 20 psi

• 25 psi

• 30 psi

Why should acetylene always be run in the upright position?

• To prevent leaks in the system

• To ensure proper fuel flow

• To avoid withdrawing liquid acetone

• To stabilize the acetylene

What should be done if there is a leak in the system?

• Open the valves completely

• Tighten all the connections

• Use soap and water to check for leaks

• Increase the working pressure

What is the purpose of the porous membrane and liquid acetone in the acetylene tank?

• To stabilize the acetylene

• To increase the fuel flow

• To prevent leaks in the system

• To provide a fuel source

How should the pressure adjustment knob be set on the acetylene regulator?

• Completely tightened

• Relatively loose

• Backed off completely

• Adjusted to the maximum pressure
