Is it still necessary to conduct an explosion-proof inspection after the installation of explosion-proof electrical equipment?

Many corporate clients are puzzled: does the fact that electrical equipment purchased with a valid and genuine explosion-proof certification can be used normally after installation mean it is ready for use? https://pic4.zhimg.com/80/v2-1e54713776a9ae25b9623e5a38c84da3_720w.jpg Does the use of explosion-proof equipment here mean that the entire system is explosion-proof? We know that every product has its life cycle, from production, introduction to the market, use by end-users, wear and tear, to eventual disposal. As special equipment used in specific industries, the lifecycle of explosion-proof devices depends not only on the devices themselves but also on how they are installed and maintained. In practice, it is common for improper use by users to cause explosion-proof electrical equipment to lose its protective properties, leading to explosion accidents, which is something that deserves serious attention. Therefore, the installation inspection of newly put into use explosion-proof equipment is particularly necessary and important. After the explosion-proof equipment is installed, an initial inspection should be carried out by a testing institution with **qualified testing capabilities before the project is handed over to the user, in order to ensure the explosion-proof safety performance of the entire project. The explosion-proof acceptance standards are based on mandatory standards such as AQ 3009, GB/T3836.15, GB/T3836.16, and GB 50257. The installation and acceptance of explosion-proof equipment is not a one-time solution. To ensure that explosion-proof equipment remains in good working condition and can be used safely in hazardous environments over the long term, it is also necessary to carry out continuous monitoring and regular inspections of such equipment while it is in use. https://pic1.zhimg.com/80/v2-e730d60cf131f6cd74e4c2961b913a28_720w.jpg Continuous monitoring should be carried out by the company’s professionals, who must also keep proper records of the inspections and address any abnormalities that are detected promptly. Regular inspections should be carried out by testing institutions with **qualified testing capabilities, with the interval generally not exceeding 3 years. Enterprises should promptly take explosion-proof remedial measures in response to the non-compliance issues identified during inspections, and file the inspection reports from third-party qualified agencies as well as details of the remedial actions with the work safety supervision and management department. Safety is no trivial matter! Never slack off on explosion prevention!
