1. The transportation means for cold storage shall meet the requirements of relevant standards.　　2. The warehouse should be reasonably partitioned and set up relevant markings to facilitate the storage, transportation and management of goods in the warehouse.　　3. Emergency lighting, door locks and alarm devices should be set up in the warehouse for self-rescue or alarm for help.　　4. The shelves in the warehouse should have sufficient strength and rigidity.　　5. Cold storage doors should be surrounded by guardrails with eye-catching markings.　　6. The assembled cold storage should be equipped with balanced windows.　　7. The machine room should be equipped with oxygen respirator, gas mask, gas suit, rubber gloves, cork, pipe clamps, acidic drinks and other necessary protective gear and rescue medicines, and be located in a location that is easy to access by a person who manages it and inspects it regularly to ensure its use. Relevant personnel should be skilled in the use of oxygen respirators and other equipment and personnel rescue methods.　　8. For the refrigeration machine room with high-voltage control cabinet and distribution cabinet, special tools and protective articles for high-voltage electricity operation should be equipped.　　Cold storage design safety requirements 1. Ammonia as refrigerant refrigeration system cold storage should be built in the surrounding population density is relatively small. 2.　　2. In the convenient operation position outside the door of the refrigeration machine room, the general switch to cut off the power supply of the refrigeration compressor should be set up, which should be able to stop the operation of all refrigeration compressors, and the relevant signs should be set up. If the machine control panel is set up in the general control room, each refrigeration compressor should be added next to the button switch.　　3. The machine room of the ammonia refrigeration system shall be equipped with accidental exhaust device; the accidental exhaust fan shall adopt explosion-proof motor, and when the refrigeration system is cut off from the power supply in the event of an accident, it shall be able to ensure reliable power supply of the accidental exhaust fan. Accident exhaust fan overload protection is appropriate to act on the signal alarm system and not directly stop the exhaust fan. Accident exhaust fan control button box should be in the ammonia compressor room door on the outside of the wall concealed.　　4. located in the outdoor condenser, oil separator and other equipment, there should be a fence, prohibit non-operators to enter, and set up signs. High-pressure liquid storage in the outdoor, there should be a sunshade.　　5. The cold storage shall be equipped with variable power distribution room, and should be as close as possible to the compressor room.　　6. Ammonia compressor room, high and low voltage distribution room shall be arranged emergency lighting, lighting duration should not be less than 30 minutes. Machine room lighting fixtures using explosion-proof lamps, illuminance should be 50-70Lx. 7. Ammonia compressor room should be installed in the ammonia concentration of automatic measuring devices, when the ammonia concentration is close to the lower limit of 10% of the explosion, it should be able to send out an alarm signal.　　8. Ammonia compressor room should be set up in the control room on the side of the machine room, starting and normal operation will produce sparks in the power equipment start-up control equipment, warehouse temperature telemetry, recording instruments should be arranged in the control room.　　9. Each refrigeration compressor, pumps, cooling towers and other equipment motor should be equipped with an ammeter; the same air cooler, evaporative condenser, etc. installed several motors can be *** with a piece of ammeter, *** with a set of control appliances and short-circuit protection appliances, but each motor should be set up separately for overload protection.　　10. The door of the machine room should be opened to the outside. The number of doors should ensure that personnel in an emergency to leave quickly.　　11. Each refrigeration compressor should be equipped with emergency stop button on the unit console.　　12. In the easy leakage of ammonia and ammonia liquid concentration of the location should be set at the top of the ammonia dilution spray device.　　13. Machine room should be set up maintenance, operation of the safety channel.　　14. Cooling room, freezing room, cold storage room, ice storage and through the hall lighting illumination should not be less than 20Lx; processing room, packaging room lighting illumination should not be less than 50Lx. 15. Cold storage warehouse lighting arrangement should avoid the ceiling air cooler and the top of the exhaust pipe, in the library operation channel focus on the light, in the cargo space can be evenly arranged.　　16. The lighting switch in the warehouse should adopt moisture-proof switch or air-tight switch, and the lighting switch of each warehouse should be centrally installed outside the door of the warehouse, and should be arranged far away from the door.　　17. When the installation height of lamps in the warehouse is equal to or less than 2.2m, AC24V safety voltage should be used. Lamps and lanterns metal shell should be connected to the protection line (PE line).　　18. Below 0 ℃ cold storage warehouse power and lighting lines should be used in copper-core low-temperature rubber-insulated cable, and should be laid.　　19. Through the warehouse insulation layer of electrical lines, must take reliable fire prevention and prevention of cold bridge measures.　　20. The attic layer of the warehouse shall not be installed electrical equipment and laying of electrical lines.　　21. The elevator of the cold storage shall be distributed by the low-voltage distribution room with special circuit.　　22. Where the use of mechanical ventilation as the underground soil freezing cold storage, ventilators should be able to automatically run according to the temperature of the underground heating layer. 23. cold storage design should meet the relevant provisions of the fire.
