Soyuz launch site

The launcher propellant storage and decanting zones are
spread out over the launch site area at a safe distance from
the pad.

Special zones are reserved for kerosene, hydrogen
peroxide, liquid oxygen and nitrogen, and compressed gases.
In addition, there are a number of service buildings in the
preparation zone about 1000 m from the pad.

These provide shelter for the ground service equipment and associated facilities, including nitrogen and helium compressors, launcher battery chargers, air conditioning and power production.
