Question: 1 / 400

What position must fuel gas cylinders be in at all times?

Sideways

Valve end down

Valve end up

Fuel gas cylinders must always be kept in a valve end up position to ensure safety during use and storage. This orientation helps to prevent the buildup of pressure that can occur if the cylinder is placed on its side or upside down, which could potentially lead to valve damage or gas leaks. Additionally, having the valve at the top allows for easy access and control when connecting to welding or cutting equipment.

Storing cylinders upright with the valve end up also minimizes the risk of the cylinder falling over, which can lead to catastrophic failures or injuries. Furthermore, in case of any accidental release of gas, having the cylinder upright ensures that the gas is released in a controlled manner from the top of the cylinder rather than from a potentially damaged valve when lying sideways or horizontally.
