What is a requirement when transporting oxygen and fuel gas cylinders on public roadways?

When transporting oxygen and fuel gas cylinders on public roadways, it is essential that they are secured properly. Securing the cylinders helps prevent them from tipping over, rolling, or being damaged during transport, which could lead to dangerous situations, such as leaks or explosions. Properly securing these cylinders not only ensures the safety of the transport vehicle and its passengers but also protects other road users by minimizing the risk of accidents.

While other options may address safety and regulatory considerations, they are not universally applicable requirements for the transport of gas cylinders. For instance, while some jurisdictions might require operators to have specific licenses, this often depends on local regulations rather than a blanket requirement for all transport. Similarly, while inspections may be necessary under specific conditions, there is no general rule mandating weekly inspections solely for transport purposes. Marking cylinders with hazardous labels is also important but primarily serves to inform others about the potential hazards rather than being a transport requirement. Therefore, ensuring that cylinders are secured is the fundamental requirement for safe transportation on public roadways.
