Seeking a PPT file for training on the interpretation of GB17681-2024

Core interpretation: GB 17681-2021 1. Standard positioning and importance Positioning: This standard is a mandatory **standard. This means that companies within the specified scope of application must comply unconditionally, as it is legally binding. Scope of application: Specifically designed for tank areas that store flammable and explosive hazardous chemicals as major hazard sources. It is not applicable to all chemical storage tanks, but only to those with the highest risk level that could lead to serious consequences. Objective: By standardizing the installation of on-site safety monitoring equipment, it is possible to achieve real-time and effective monitoring of key safety parameters in tank areas, thereby improving the ability to detect accidents early and respond to them promptly, and preventing the occurrence of severe accidents. 2. Main new additions and revisions (compared to the previous version) This standard represents a comprehensive upgrade from the 1999 version, with significant changes in its technical aspects. These changes are mainly reflected in the requirements regarding the \"systematic nature\" and \"reliability\" of monitoring equipment: moving from a single approach to a systematic one – it is no longer sufficient to simply install a few instruments; instead, a complete on-site safety monitoring system must be established, with emphasis on the interaction between various devices and their integration into a cohesive system. Emphasis on functional safety: Higher requirements are placed on the reliability and availability of sensors, controllers, actuators, etc., which are used for interlock control; in some scenarios, a certain level of safety integrity (SIL) must be achieved. \"Comprehensiveness\" and \"targeted nature\" of monitoring parameters: The parameters that must be monitored are more clearly defined; it is mandatory to continuously monitor key process parameters such as level, temperature, pressure, and flow rate. New leakage monitoring requirements: It is explicitly stipulated that detectors for flammable and toxic gas leaks must be installed, with specific guidelines provided regarding the type of detectors, the density of their placement, and their installation location (taking height and wind direction into account). Strengthen ****: It is required to conduct thorough **** of key areas such as the tank top platform, the areas inside and outside the fire dike, control valves, and main passages, without any blind spots, and to integrate this with parameter alarms. \"Mandatory\" and \"precise\" nature of alarm and interlock control: High and low level alarms and interlocks: It is required to have an alarm for high liquid levels that triggers the interlock to shut off feeding, as well as an alarm for low liquid levels that triggers the interlock to stop the pump. This is the core defense against tank overfilling and emptying accidents. Fire alarm and interconnection: Flame or heat detectors are required, and the alarm signal should be able to automatically activate fire extinguishing systems such as foam and water spray systems. \"Guarantee\" requirements for power supply and explosion protection: Power supply for Class I loads: The power supply requirement level for the monitoring system (especially the interlock control section) should be Class I, to ensure that in the event of a power outage, a backup power source can switch in seamlessly, thus maintaining the continuous operation of the system. Explosion protection rating matching: All monitoring equipment installed in areas prone to explosions must have an explosion protection rating that precisely matches the classification of those hazardous areas. 3. Main impacts on enterprises and recommendations for response: Increased compliance costs: Enterprises need to conduct a thorough inspection of existing tank areas that do not comply with the new regulations and carry out technical upgrades, which involve investments in various aspects such as instruments, control systems, cables, and installation work. Rising technical requirements: Companies need to have or acquire professional personnel who understand functional safety, SIL assessment, and system integration, or they can turn to qualified third-party service agencies. Increased management responsibilities: The new standards impose stricter requirements for the regular inspection, calibration, maintenance, and testing of monitoring equipment. Enterprises must establish and improve relevant management systems and record archives. Proactive emergency response capability: The standards incorporate certain emergency response actions (such as automatic shutdown and automatic fire suppression) into the interlock system, requiring enterprises to have a higher level of automation and maintenance capabilities. 4. Recommended implementation steps: Gap analysis: Compare with GB 17681-2021 to systematically examine the gaps in existing tank farms regarding the installation of monitoring equipment, parameter monitoring, alarm interlocking, system integration, and other aspects. Design modification: Entrust a qualified design firm to prepare a modification design plan based on the results of the gap analysis. Procurement and construction: Equipment that meets standard requirements is purchased, and professional teams carry out the installation work. Acceptance testing: Conduct system debugging and interlock function testing, and complete the final acceptance. Documents and training: Update operating procedures and maintenance procedures, and provide specialized training for operators and maintenance staff. Important note: If you are asking about standards in other fields (for example, “GB/T 17681” may be related to information technology), please provide more complete information. Safety production standards must be strictly followed; incorrect application may lead to compliance risks. For enterprises dealing with major hazard sources, GB 17681-2021 represents a mandatory requirement that demands immediate action; it is recommended to organize specialized training and compliance assessments as soon as possible. When carrying out the implementation, it is essential to comply with the relevant regulations and industry standards issued by the Ministry of Emergency Management, and to consult professional safety assessment or engineering design agencies.
