Why must gas cylinders always be transported in a secure and upright manner?

Transporting gas cylinders in a secure and upright manner is critical primarily to prevent accidents such as tipping and breaking valves. When gas cylinders are upright, the risk of them falling over is minimized, which helps avoid potential damage to the cylinder and its safety features, such as the valve. If a cylinder were to tip, the sudden release of gas could create a dangerous situation, including the risk of a gas leak or explosive conditions, especially if the cylinder is pressurized. Ensuring they are secure during transport adds an additional layer of safety by minimizing movement and maintaining stability.

The other considerations, while relevant in different contexts, do not address the primary concern for safety. For instance, easy access may not be a priority in situations where safety is at risk, governmental regulations on gas transport often focus on safety rather than convenience, and saving space may compromise safety protocols that prioritize secure handling and transportation of compressed gases.
