5.2 Environmental Requirements for Device Operation

5.2.1 Environmental Requirements for an Equipment Room
Requirements for Selecting a Site for an Equipment Room
When designing a project, consider the communication network planning and technical
requirements of the equipment. Also consider hydrographic, geological, seismic, power supply,
and transportation factors.
Construction, structure, heating and ventilation, power supply, lighting and fire fighting of the
equipment room should be designed by specialized construction designers to suit the
environmental requirements of devices. The equipment room should also follow local
regulations concerning the industrial construction, environmental protection, fire fighting, and
civil air defense. Construction must conform to government standards, regulations, and other
requirements.
The equipment room should be located at a place free from high temperature, dust, toxic gases,
explosive materials, or unstable voltage. Keep the equipment room away from significant
vibrations or strong noises, as well as power transformer stations.
The specific requirements for selecting a site for equipment room are as follows:

The room should be located at a distance of at least 5 km (3.11 mi.) from heavy pollution
sources such as smelting and coal mines. It should be located at a distance of at least 3.7
km (2.30 mi.) from moderate pollution sources such as chemical, rubber, and galvanization
factories. It should be located at a distance of at least 2 km (1.24 mi.) from light pollution
sources such as packinghouses and tanyards. If these pollution sources cannot be avoided,
ensure that the equipment room is upwind of the pollution sources. In addition, adopt a
high-quality equipment room or protection products.
The room should be located away from livestock farms, or in the upwind of the livestock
farms. Do not use an old livestock room or fertilizer warehouse as the equipment room.
The equipment room must be far away from the residential areas. The equipment room that
is not far away from the residential areas must comply with equipment room construction
standards to avoid noise pollution.
The doors and windows of the equipment room must be closed to keep an airtight room.
Using steel doors to ensure sound insulation is recommended.
No cracks or openings are allowed on the walls or floors. The outlet holes on the walls or
windows must be sealed. Walls must be constructed in the smooth, wear-resistant, dustproof
principles and produce the effect of flame retardant, sound insulation, heat absorption, dust
decrease, and electromagnetic shielding.
The air vent of the room should be far from the exhaust of city waste pipes, big cesspools
and sewage treatment tanks. The room should be in the positive pressure state to prevent
