How often should explosion-proof electrical equipment be inspected?
Thread Content
Installing and using explosion-proof electrical equipment in explosive hazard areas is basic common sense. Using qualified explosion-proof electrical equipment can minimize the likelihood of explosive accidents. However, as a consumable item. During use, as the operating time of explosion-proof electrical equipment increases, its performance will decline. Furthermore, insufficient or inadequate knowledge of explosion protection among maintenance personnel can lead to failures in the explosion-proof functionality of electrical equipment during maintenance, resulting in a decrease or even loss of its explosion-proof properties. https://pic2.zhimg.com/80/v2-cccf9b0fcee1dff94d8caae9c52ecffd_720w.jpg To this end, corresponding standards were established, namely AQ 3009-2007 \"Code for Electrical Safety and Explosion Protection in Hazardous Areas\". This standard specifies that explosion-proof electrical equipment in use must be sent to a testing center with specialized expertise in explosion protection at least once every three years for inspections regarding its performance, installation, and maintenance. Any deficiencies detected during these inspections must be addressed promptly, and the inspection reports along with details of the corrective actions taken must be filed with the department responsible for supervising work safety. In actual use, many companies, for the sake of their own safety, also conduct regular inspections of the explosion-proof electrical equipment they use in order to minimize the likelihood of risks occurring.
If the safety authorities conduct an inspection, action must be taken: lol In fact, companies should also carry out self-inspections for their own safety
My previous company was investigated; it seems there aren’t many qualified agencies, and it’s very expensive to work with them
This also depends on the area and the number of electrical components
If inspections are carried out strictly in accordance with regulatory requirements, it might be possible to determine that your company is bankrupt. The most proper approach is to hire companies such as SGS or TUV to conduct a 360° inspection of everything related to explosion-proof areas: the explosion-proof equipment itself, the procedures for managing such equipment, the operations and maintenance activities in those areas, as well as the tools used for maintenance. The cost varies; generally, it starts at around 100,000 yuan, and for an area of 10,000 square meters, the cost is roughly 1 million yuan. A slightly less formal approach involves hiring the Nanyang Explosion Protection Research Institute or the Shanghai Instrumentation and Explosion Protection Research Institute for inspections; the main things checked are the explosion-proof markings on the equipment, grounding connections, etc. The cost depends on the level of risk, ranging from a few dozen yuan to over a hundred yuan per square meter. An even less formal approach is to use local safety assessment companies that have good relationships with the safety supervision authorities, in order to obtain a report just to meet the requirements of those authorities; the cost in this case is usually 20-50% of the prices mentioned above. The most irregular approach is to do nothing and wait until someone discovers it before taking action. Since there are many companies that don’t do it, even if it’s detected, they will be given time to make corrections; no fines will be issued immediately
Amazing! In the end, we found a company under the Jiangsu Provincial Work Safety Supervision Bureau, which was recommended by the local work safety supervision authority. Both Nanyang and Shanghai quoted prices of over 300,000 yuan each; this company, however, quoted only 110,000 yuan :lol
When coming to our company for inspection, only the test reports for insulating mats, insulating gloves, insulating shoes, and lightning rods are checked.
Of course, the inspection items vary depending on the type of enterprise
