Cylinders in transit must be fastened to protect against what?

Cylinders in transit must be fastened to protect against movement, tipping over, and physical damage. Ensuring that they are secured prevents the risk of the cylinders rolling or falling during transport, which could lead to dangerous situations, such as ruptures or leaks of the gas contained within them. By fastening the cylinders, you help maintain their stability and integrity, minimizing the potential for accidents and ensuring the safety of both the transport vehicle and those nearby.

The correct answer emphasizes the importance of safety measures during the transit process. When cylinders are properly secured, it reduces the likelihood of incidents that could result in hazardous gas leaks or physical harm to people and property.
