Secure vessels against falling over!

Secure standing cylinders against falling over and lying cylinders from rolling away.

Do not throw pressure vessels!

When falling, the containers may become severely deformed so that they may be torn open. The refrigerant evaporates immediately, releasing violent forces. Flying fragments of cylinders can cause severe injuries. Bottle valves can brake during improper transport. To protect cylinder valves, bottles may be transported only with protective covers screwed on.

Do not place near radiators!

High temperatures can occur near radiators. Higher temperatures however also mean higher pressures, which may exceed the rated pressure of the vessel.

Do not heat above 50 °C

To prevent danger, the Regulations for Pressure Tanks provide that tanks shall not be heated to more than 50 °C.

Do not apply uncontrolled heat

Do not heat with an open flame under any circumstance. The local overheating that will result can change the structure of the container's materials, thereby reducing the safe maximum pressure limit of the container. In addition, the danger arises that the refrigerant decomposes due to localised overheating.

Seal empty containers

Empty refrigerant containers must in all cases be sealed so as to prevent intrusion of moisture. Moisture causes steel containers to rust. This weakens the walls of the containers. In addition, rust particles which enter the refrigerant system from the container cause malfunctions.
