Requirements for Selecting a Site for an Equipment Room

Requirements for Selecting a Site for an Equipment Room

When designing a project, you should consider the communication network planning and the technical requirements of the equipment. You should also consider hydrographic, geological, seismic, power supply, and transportation factors.

Construction, structure, heating and ventilation, power supply, lighting and fire prevention of the equipment room should be designed by specialist construction designers according to the environment requirements of the equipment. The equipment room should also follow the relevant industrial, environment protection, fire prevention, and civil defense regulations.

The equipment room should be located at a place free from high temperatures, dust, toxic gases, explosive materials, or unstable voltage. Also ensure that the equipment room is located away from sources of large vibrations, loud noises, and power stations.

The specific requirements for selecting a site for an 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 smelteries and coal mines. It should be located at a distance of at least 3.7 km (2.30 mi.) from medium 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 food processing factories. If these pollution sources cannot be avoided, ensure that the equipment room is upwind of the pollution sources and take extra measures to prevent the pollution from affecting the equipment room.
  • The room should be located away from livestock farms, or, if unavoidable, upwind of the livestock farms. Do not use an old livestock room or fertilizer warehouse as the equipment room.
  • The air vent of the room should not be located near to the output of any sewage works. Ensure that the equipment room is correctly pressurized so that corrosive gasses are not drawn into the room.
  • The room should be located away from industrial and heating boilers.
  • You are recommended to locate the room in or above the second floor. If this requirement cannot be met, the ground for equipment installation in the room should be at least 600 mm (23.62 in.) above the maximum flood level in the local record. The room should be at an altitude of lower than 3000 m (118.11 in.).
  • The room should be at least 3.7 km (2.30 mi.) away from the sea and salt lakes. If this is not possible, the equipment room should be airtight with cooling facilities. In addition, alkalized soil cannot be used as the construction material. If this is not possible, the equipment must be suitable for use in wet conditions.
  • The equipment room should be strong enough to resist strong wind and downpours.
  • The room should be located away from large sources of dust or sand. If this is unavoidable, the doors and windows of the equipment room must face away from the source of dust or sand.
