What safety issues should be noted during the maintenance process of the cold box? What safety issues should be noted during the maintenance process of the cold box?
During the maintenance process of the cold box, key issues such as electrical safety, low-temperature protection, operating standards, equipment protection, and environmental safety should be given special attention. The following are specific instructions:
Electrical safety:
Power off operation: Before any repair or maintenance of the cold box, the equipment power must be cut off to prevent electric shock accidents. During maintenance, ensure that the power plug and socket are kept clean and dry to avoid water ingress and looseness.
Line inspection: Regularly check whether the connections of wires, plugs, and sockets are good, whether they are damaged or loose, to ensure the safety and reliability of the electrical system.
Low temperature protection:
Wear protective equipment: The temperature inside the cold box is extremely low, and maintenance personnel should wear low temperature resistant protective clothing, gloves, and goggles to prevent frostbite.
Avoid prolonged exposure: Try to shorten the operation time inside the cold box as much as possible, and if necessary, rotate the operation to avoid the long-term impact of low temperature environment on the human body.
Operating standards:
Follow the manufacturer's guidelines: Strictly follow the maintenance manual and operating procedures provided by the manufacturer for maintenance, and do not disassemble or modify key components without authorization.
Professional operation: Maintenance of complex components such as refrigeration systems and electrical systems should be carried out by professional technicians to avoid safety accidents caused by improper operation.
Equipment protection:
Prevent mechanical injury: During maintenance, be careful to avoid being scratched or pinched by sharp or moving parts inside the cold box, such as fans and compressors.
Avoid heavy pressure: Do not place heavy objects on the cold box door or top cover to prevent deformation of the door or top cover under pressure, which may cause sealing failure or structural damage.
Environmental safety:
Good ventilation: The area around the cold box should be well ventilated to avoid operating in a confined space and prevent oxygen deficiency or poisoning caused by refrigerant leakage.
Fire and explosion prevention: Flammable and explosive materials are not allowed to be stored around the cold box. Smoking or the use of open flames is strictly prohibited during maintenance to prevent fire or explosion accidents.
Cleaning and maintaining safety:
Use appropriate cleaning agents: When cleaning the cold box, neutral detergent should be used, and corrosive, volatile, or flammable and explosive cleaning agents should be avoided to prevent harm to equipment or human body.
Prevent water splashing into electrical components: During the cleaning process, avoid splashing water into the compressor compartment or other electrical components to avoid reducing electrical insulation performance and causing accidents.
Emergency Management:
Familiar with alarm systems: Understand the meaning of alarm prompts for cold boxes, such as abnormal temperature, doors not tightly closed, power failures, etc., and be able to take timely measures based on the alarm prompts.
Prepare emergency equipment: Equip the cold box maintenance site with emergency equipment such as fire extinguishers and first aid kits, and ensure that maintenance personnel are familiar with their usage methods.
