This advice does not supersede existing requirements for safe transport of cylinders of gas for medical purposes (such as oxygen), cylinders installed correctly in or on a caravan or mobile home, or to the commercial delivery of cylinders.

Do

• Check for leaks by brushing on soapy water (or water from the windscreen wash bucket at service stations) and looking for bubbles. Smell is not always a reliable test.
• Ensure windows of the vehicle are wound down for cross flow ventilation, or use a suitably ventilated cabinet.
• Disconnect any attachments used with the cylinder before transport, and close the cylinder valve.
• Keep the cylinder upright when transporting it in a trade vehicle or a car.
• Store or keep the cylinder in a vehicle only if there is a purpose built compartment, cabinet or tool box that provides adequate ventilation to allow any leaking gas to drain to the outside of the vehicle. Also make sure there are no ignition sources around when opening the compartment to take the cylinder out.
  An open vehicle such as a utility provides the best ventilation and avoids the risk of gas accumulation.
• Unload the cylinder from inside the vehicle immediately when reaching your destination, unless the vehicle has a suitable compartment or cabinet as above.

Don’t

• Do not put a cylinder in any vehicle without first checking for gas leaks.
• Do not carry a cylinder in the car with the car windows wound up.
• Do not lay a small LP Gas cylinder on its side (or upside down). Make sure that it is securely packed in a way that prevents it from tipping over in transit.
• Do not store or keep a cylinder in a van without a purpose-built ventilated compartment.
• Do not leave equipment and accessories attached to the cylinder when transporting.
• Do not carry a cylinder mounted external to the profile or body of a vehicle.
• Do not carry or keep a cylinder in an enclosed toolbox, especially with loose tools.
