Question: 1 / 400

Can acetylene cylinders be used in any position?

Yes, they can be used in any position

No, they may only be used upright

Acetylene cylinders are designed to be used in an upright position due to the nature of acetylene gas. In its cylinder, acetylene is dissolved in a solvent, typically acetone, which helps keep the gas stable and prevents it from separating from the solution. When these cylinders are used upright, the gas is drawn from the solvent in a controlled manner, ensuring safe and effective operation.

Using acetylene cylinders in any other position, such as horizontal or at an angle, could lead to the risk of the gas escaping in an uncontrolled manner. This can create hazardous situations, including the potential for explosive mixtures and fire hazards. Therefore, utilizing the cylinders only in an upright position maintains safety and compliance with national safety standards.
