2. Handling chlorine

2.1 Physical and chemical data

Under normal conditions of pressure and temperature, chlorine is

a yellowish green gas with a pungent odour. It exists as diatomic

molecule Cl

2

.

It is not flammable, but can under certain circumstances promote

the flammability of metals, hydrocarbons etc.

Warning

Unauthorised structural modifications to the system

may result in serious damage to equipment and

personal injury.

It is forbidden to open, modify, change the structure

of, bridge, remove, bypass or disable components,

especially safety equipment.

• Irritating to eyes, respiratory system and skin.

• Causes whooping cough.

• Causes causticization of skin and respiratory system.

• Lethal by lung edema in case of long influence or high

concentration.

• Slight paralyzing effect to the central nervous system.

Hazards of liquid chlorine

• Calm down injured persons and keep them warm with

blankets.

• Supply fresh air; use oxygen respirator (alternately with

inhalating steam), if possible.

– No mouth-to-mouth resuscitation!

• Fast and gentle transport to hospital

– lying

– sitting in case of difficulty in breathing

– state chlorine causticization as the cause.

First aid after causticization of the skin

• Keep calm.

• Remove contaminated clothes.

• Rinse skin with plenty of water

2.2.5 Transport and storage of chlorine

Basic rules for transport and storage of chlorine

• Treat containers carefully, do not throw!

• Protect containers from turning over or rolling away!

• Protect containers from direct sun rays and temperatures over

50 °C!

protection cap.

Valid regulations

– Regulations for accident prevention "Chlorination of water"

(GUV-V D5) with process instructions

– Regulations concerning places of work (ArbStättV)

– Technical rules for gases 280, 310 und 330

Warning

R 23 Toxic by inhalation.

R 36/37/38 Irritating to eyes, respiratory system

and skin.

Caution

Further obligations of the operating authority

Warning

Handling of chlorine containers only by experienced,

practised personnel!

Warning

This rules are valid for both full and empty

containers, as empty containers still contain rests of

chlorine and therefore are under pressure.

Warning

Strictly observe local law and regulations for

handling, transport and storage of chlorine.

English (GB)

2.2.6 Pressure vessels and mountings

Chlorine is being offered in two container designs:

• Steel cylinders containing 50 kg or 65 kg, equipped with one

valve for

– the withdrawal of gaseous chlorine from the upright standing

cylinder

Variant of chlorine cylinder

Fig. 3 Variant of chlorine cylinder

• Steel drums containing 500 kg or 1000 kg, equipped with

– one valve for the withdrawal of gaseous chlorine

– one valve for the withdrawal of liquid chlorine

Fig. 4 Chlorine drum

Fig. 5 Valve position of chlorine drum

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.

Chlorine containers are marked by grey colour.

• No changes or repair by the user!

• Never open container valves by force. Stuck valve spindels

can be loosened by wrapping a shred with warm water around

the valve.

– Never use an open flame!

– Never use wrench lengthening!

– Return containers with stuck valves to the manufacturer.

• Observer safety precautions and the manuals of the

manufacturer!

2.2.7 Chlorine extraction

Before the extraction

• The chlorine containers must be stored at least for 8 hours in

the container room so that the content can adapt the ambient

temperature.

• Turn chlorine drums on the support until the dip pipe and the

riser pipe are placed vertically (observe the markings on the

drum).

• Check tightness.

Connection

• Protect containers from turning over or rolling away!

• Dry the piping and the withdrawal system with dry nitrogen or

dry air.

• No foreign matter must get into the plant.

• Mount new gaskets to the connection line.

• Connect the container.

• Slowly open the container valve.

Withdrawal of gaseous chlorine

In case of higher chlorine requirement several chlorine containers

of the same temperature have to be connected with header lines.

Withdrawal of liquid chlorine

• Within chlorination plants only possible from chlorine drums.

• Application of an evaporator is necessary.

• Withdrawal of gaseous chlorine:

Observe residual pressure of ca. 2 bar.

• Withdrawal of liquid chlorine:

Observe residual pressure of ca. 4 bar.

After the extraction

• Close container valve.

• Disconnect container from the plant.

• Screw on valve protection nuts.

• Screw on protection cap.

2.3 Checking the tightness

Before commissioning check the tightness of the whole plant.
