3.5 Physical and chemical data of chlorine
Under normal conditions of pressure and temperature, chlorine is
a yellowish green gas with a pungent odour, which exists as Cl
2
molecule.
It is not flammable, but can promote the flammability of metals,
hydrocarbons, etc.

4. Construction and function
4.1 Description of the device
A header line connects several gas containers with the
components of the gas dosing system. A header line consists of
connection valves (5) for connection of the container to the
flexible line (3), a T-piece (2) and a rigid collector pipe (1).
The connection valves (5) can be closed in case of container
exchange.
Fig. 10 Assembled header line
4.2 Function
When several gas containers are connected to a header line, the
gas extraction quantity in the gas dosing system increases by the
number of connected containers.
The maximum extraction quantity must not exceed 1 % of the
container filling quantity. Otherwise the gas will liquefy during
extraction.
If a gas container is empty, it can be exchanged. Before container
exchange, the connection valve must be closed by fastening the
lock nut (4) as far as it will go.
