4.4 Gas connections
General information for safe handling of gas cylinders:
• Store and use gas cylinders only in well ventilated areas.
• Open the gas cylinder valve slowly to avoid pressure surges.
• Secure gas cylinders during storage and use against falling (chaining).
• Transport gas cylinders with a cylinder cart, do not carry, roll, or throw them.
• Always close the valve even with apparently empty cylinders; screw on the cap when not in
use. Return gas cylinders with the valve closed.
• Do not open gas cylinders by force. Mark them when damaged.
• Protect gas cylinders against fire, e.g. do not store together with flammable liquids.
• Observe relevant regulations for dealing with gas cylinders.
Secure the gas cylinders against falling and other mechanical damage.
WARNING
