【 Weak current College 】 and medium cold storage security problems and countermeasures 】

Along with the rapid development of animal husbandry, the increasing number of small and medium-sized refrigerator. But most cold storage in non-compliance with the relevant approval procedures, "deficient" phenomenon is more prevalent. According to the current and medium cold storage problems, the authors suggest some solution proposals and measures. I. current and medium cold storage problems 1. refrigeration equipment security and automatic control by the cold store design code (GB50072-2001) of the regulations. Part of the relief valve pressure tube connected together, not separately, the height is insufficient; glass tube liquid level indicator no protection facilities; equipment with ammonia and ammonia pipeline is not marked clear color, on the tube media flows which are not clearly marked as not in compliance with the cold store design code. 2. the liquid ammonia plant electrical design did not abide by the explosion and fire hazard environment electrical installation design code (GB50058-92), the petroleum chemical industry enterprise production plant power design specification (SH3038-2000) and the petrochemical electrostatic grounding design code (SH3097-2000). Some units of distribution cabinet not earthed connection, electric control device, lighting not explosion-proof, ammonia, without static grounding protection, explosion-proof design partial motors, power distribution, and compression engine room connected, not real wall of separation, does not comply with the above specifications, seriously affecting production security. 3. cooling machine room, warehouse design according to the architectural design fire protection standard (GB50016-2006) and the oil-chemical enterprise design fire protection standard (GB50160-92) of the regulations. Part of the refrigerator without fire department fire inspection, fire extinguisher expired not checked, with amounts, part of the refrigeration machine room and distribution within the open door, no emergency lighting and fire evacuation signs. 4. the annex to the safety of pressure vessels and are not under the pressure vessel safety provisions of the Statute of the monitoring carried out inspection and testing. Some units of pressure pipelines and pressure vessels, the relief valve is not periodic testing, some life long, serious corrosion, some are already detected, but provide no qualified intermediaries in the test report. 5. safety management are not in place. As the use of dangerous chemicals, most failed to set the safety management of institutions or equipped with dedicated security personnel, inadequate safety management responsibility, safety management systems and procedures is not established or not in line with the actual, not to establish emergency response plan, equipped with a gas mask must be private, not regularly organized walkthrough, part of special operations personnel without specialized security training, competition for jobs without a license. 2. solve the problem of recommendations and measures 1. as soon as possible the related regulations, or normative documents, clearly define the nature of the cold storage units, liquid ammonia uses the unit directly into the hazardous chemicals used units, and the production, storage and management of dangerous chemicals unit, in accordance with the hazardous chemicals management, strict market access threshold, strict security conditions justify and safety assessment, fundamentally resolve deficiencies. 2. construction, fire, electric power, quality, safety and other related departments carry out their duties, mutual cooperation, concerted, strict implementation of relevant norms and standards, policy, source stopped cold storage building and safety supervision. 3. the implementation of enterprise safety in production responsibility. Improve enterprise security directors, production managers and practitioners, in particular the refrigerant special operations personnel safety awareness, strict implementation of the safety in production responsibility system, enhance the quality of security personnel, strict implementation of the rules and procedures, improving emergency personnel capacity and ability to protect themselves. 4. strengthen the monitoring, in strict accordance with national laws and regulations and national standards, industry standards, and urge enterprises to continuously upgrade the management level. Strict law enforcement monitor, investigate and freezer units of safety violations.
