1.5 Handling chlorine containers

Chlorine is stored in grey steel cylinders or drums in lockable
chlorine rooms. Due to safety precautions, chlorine containers
are only filled up to 95 % of their capacity.
Kind of gas, weight, owner, producing date and date of the last
testing have to be noted clearly on the container.
Observe the following:
• Store chlorine containers fireproof.
• Protect chlorine containers from heat and sunlight.
• Chlorine containers should not be modified or repaired by the
user.
• Keep full and empty containers closed.
1.5.1 Steel cylinders
• Contents: 50 kg or 65 kg

1.5.3 Basic rules

Warning
Handling of chlorine containers only by experienced
personnel.
Observe safety regulations for chlorine containers.
• Treat containers carefully, do not throw!
• Protect containers from turning over or rolling away, e.g. with
chains or clips.
• Protect containers from direct sunlight and temperatures over
50 °C.
• Transport containers only with valve protection nut and
protective cap.
Warning
These rules apply for both full and empty containers,
as empty containers still contain rests of chlorine and
therefore are under pressure.
