Safe use of gas in cylinders

To work properly, rationally and safely with butane-propane mixtures or propane, the user must know the basic characteristics of the gas in its liquid or gaseous state. The user must wear the mandatory personal protective equipment when handling the gas.

Employees working with gases must be properly trained in accordance with the requirements of the legal regulations.

Safe cylinder connection and replacement

• Make sure the valves on both cylinders are closed.
• Inspect and replace the regulator seal.
• Screw the regulator onto the cylinder valve.
• Open the valve. Check the connection between the valve and the regulator with a dedicated spray or soapy water.
• If the joint between the valve on the cylinder and the regulator does not seal, close the valve on the cylinder and inspect the seal and the bearing. Re-tighten the regulator and check for leaks.
• If the joint is still leaking, close the valve, take the cylinder to an open area and inform your supplier.
