5.1.1 Connecting the oxygen cylinder
Oxygen cylinders are pressurized and filled with highly compressed
oxygen. Typical sizes are 1, 2, or 10 liters. Observe the following safety
information when connecting oxygen cylinders:
CAUTION
Pressurized gas cylinders may only be used by instructed and experienced personnel.
CAUTION
Pressurized gas cylinders may not be thrown and must be protected from tipping over
during storage and use.
CAUTION
Use oxygen cylinders only with a pressure regulator approved for oxygen (look for
"Oil and grease free" labeling!). Only approved pressure regulators according to
DIN EN ISO 10524 or ones with special approval may be used together with oxygen.
Only approved (original) seals and metal connectors may be used when connecting
pressure regulators.
CAUTION
Adjustable pressure regulators must always be relieved (pressure adjustment screw all
the way turned out) before applying pressurized oxygen.
CAUTION
Pressurized gas cylinders must be protected from dangerous heating (> 50° C),
e.g. from heaters or open flames.
CAUTION
Handle the valves of oxygen cylinders manually only and open them slowly. Always
point the valve opening and handwheel away from the body.
