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
• Extract chlorine gas from the upright standing cylinder via the
valve.
Fig. 1 Design of cylinder
1.5.2 Chlorine drums
• Contents: 500 kg or 1000 kg
• Extraction of chlorine gas via the riser pipe valve.
• Extraction of liquid chlorine via the dip pipe valve.
Fig. 2 Design of drum
1.5.3 Basic rules
• 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.
1.5.4 Valid regulations
In Germany, the following regulations apply:
• Regulations for accident prevention "Chlorination of water"
with process instructions (GUV-V D5)
• Regulations concerning places of work (ArbStättV)
• Technical rules for pressurized gases (TRG 280, 310 and 330)

Warning
Handling of chlorine containers only by experienced
personnel.
Observe safety regulations for chlorine containers.
Warning
These rules apply for both full and empty containers,
as empty containers still contain rests of chlorine and
therefore are under pressure.
Warning
Local laws and regulations for handling, transport
and storage of chlorine must be observed.

1.6 Chlorine rooms
Chlorine rooms are rooms, where a chlorine gas dosing system
and/or chlorine containers are located. The chlorine in these
rooms is under pressure.
1.6.1 Regulations for chlorine rooms
According to the German regulations for accident prevention
"Chlorination of water", such rooms have to meet the following
requirements:
• They should not have connections to other rooms, and must
be separated gas-tight and fire-resistant.
• They must be at ground level, dry and air-conditioned.
The recommended room temperature is 18-20 °C. It should be
neither lower than 0 °C nor higher than 50 °C.
• Overpressure lines of dosing equipment must not end in the
open air.
• Ventilation openings leading into the open air must be limited
to 2 x 20 cm2.
• Appropriate exhaust devices with downstream absorption
systems must be installed.
• Chlorine gas must not get into lower-lying rooms, shafts, pits,
canals or aspirating holes of ventilation systems.
• Chlorine rooms must be equipped with a water sprinkling
system to precipitate the escaping chlorine gas.
– The sprinkling system must have a run-off with air trap.
– Operation must be possible manually from outside the
chlorine rooms.
• A chlorine gas warning system must be installed
– with optical and acoustical alarm device,
– with connection to the water sprinkling system,
– with a warning system that reactivates automatically after
switch-off (e.g. for container exchange).
• The floor of a chlorine room must be even, the exit not below
ground level and not higher than a possible loading ramp.
Fig. 3 Requirements of chlorine rooms
• Chlorine rooms must have a direct exit to the open air.
• Doors must be lockable, open outwards, and it must be
possible to open the doors without a key from inside the room.
• Chlorine rooms must not be dedicated for the permanent stay
of people.

plant: Access only for instructed persons"
Inside a chlorine room, the mandatory sign "Use the gas mask"
and the "Instruction sheet for first aid in case of chlorine gas
intoxications" must be installed.
