1　In the storage area there shall be clear zone boundaries and fire fighting passages，with reliable fire fighting facilities and effective lighting.

2　The storage location of large equipment shall be arranged reasonably according to the construction sequence and transport conditions as per construction organization design，to reduce rehandling.

3　Equipment shall be supported and backed stably and reliably，the storage area shall have proper water drainage，and with measures against collision，freezing，moisture，dust and toppling.

4　The storage location and shelves shall have sufficient bearing capacity.

5　In coastal area with salty air and corrosive environment，special measures shall be made to protect equipment from rusting.

6　Instruments，meters and precision components shall be placed on shelves or in constant temperature stores as required.

7　Pipe materials，fittings and parts shall be clearly marked and stored by category，to avoid confusion.

8　For equipment protected with nitrogen，the nitrogen pressure and equipment sealing condition shall be checked periodically.Nitrogen shall be supplied in time when the pressure is below 3.5kPa.

9　For electrical，I&C and other equipment with special requirements，measures to prevent small animals from intrusion shall be made.
