| Handling pressure vessels |
| Secure vessels to prevent them falling over. |
| Secure upright cylinders to stop them falling over and cylinders lying flat to stop them rolling away. |
| Pressure vessels must never be thrown. |
| If dropped, the vessels could be so severely deformed that they rupture. The refrigerant evaporates immediately, liberating considerable force. Flying fragments of cylinders can cause severe injuries. |
| To protect the valves, cylinders may only be transported with the protective cap screwed on. |
| Valves may break off if cylinders are not properly transported. |
| Never store in the vicinity of radiators. |
| High temperatures may occur in such areas. High temperatures are also accompanied by high pressures and the maximum permissible vessel pressure may be exceeded. |
| Never heat to above 50 °C |
| To avoid possible risk, pressure vessel regulations specify that vessels are not to be heated to in excess of 50 °C. |
| Do not heat in an uncontrolled manner |
| Do NOT heat with a naked flame. Local overheating can cause structural changes in the material of the vessel, which then reduce its ability to withstand pressure. There is also a danger of refrigerant decomposition due to localised overheating. |
| Empty refrigerant vessels must always be sealed to prevent the ingress of moisture. Moisture causes steel containers to rust. This weakens the vessel walls. In addition, any rust particles which enter refrigeration systems from storage vessels will cause malfunctioning. |
