Red Seal Welding Practice Exam

Question: 1 / 400

What should you do with the oxygen cylinder valve?

Open it fully

Close it

The oxygen cylinder valve should be closed when not in use to prevent any accidental release of oxygen. Closing the valve is a critical safety measure, as it reduces the risk of fires or explosions because oxygen supports combustion. Oxygen can intensify fires, making it dangerous if the cylinder is left open in an uncontrolled environment.

When the cylinder is not actively being used, ensuring the valve is closed helps maintain the integrity of the cylinder and is fundamental to safe handling practices in welding and cutting operations. Proper training and following safety protocols are essential when handling gas cylinders to ensure a safe working environment.
