Appendix D Site Selection
The equipment room should be at least 5 km away from the heavy pollution source such as the smelter, coal mine,
and thermal power plant, 3.7 km away from the medium pollution source such as the chemical industry, rubber
industry, and electroplating industry, and 2 km away from the light pollution source such as the food manufacturer
and leather plant. If the pollution source is unavoidable, the equipment room should be located on the windward side
of the pollution source perennially with advanced protection.
The equipment room should be at least 3.7 km away from the sea or salt lake. Otherwise, the equipment room must
be sealed, with air conditioner installed for temperature control. Saline soil cannot be used for construction. Otherwise,
you should select devices with advanced protection against severe environment.
Do not build the equipment room in the proximity of livestock farms. Otherwise, the equipment room should be located
on the windward side of the pollution source perennially. The previous livestock house or fertilizer warehouse cannot
be used as the equipment room.
The equipment room should be firm enough to withstand severe weather conditions such as windstorm and heavy
rain as well as away from dust. If the dust is unavoidable, keep the door and window away from the pollution source.
The equipment room should be away from the residential area. Otherwise, the equipment room should meet the
construction standard in terms of noise.
Make sure that the air vent of the equipment room is away from the sewage pipe, septic tank, and sewage treatment
tank. Keep the equipment room under positive pressure to prevent corrosive gas from entering the equipment room
to corrode components and circuit boards. Keep the equipment room away from industrial boiler and heating boiler.
The equipment room had better be on the second floor or above. Otherwise, the equipment room floor should be 600
mm higher than the highest flood level ever recorded.
Make sure that there are no cracks or holes in the wall and floor. If there are cable entries in the wall or window, take
proper sealing measures. Ensure that the wall is flat, wear-resistant, and dust-free, which must meet requirements of
flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
Keep the door and the window closed to make the equipment room sealed.
The steel door is recommended for soundproofing.
Sulfur-containing materials are forbidden.
Pay attention to the location of the air conditioner. Keep the air conditioner from blowing wind straight toward the
device or blowing water drops from the window or air vent toward the device.
