Do the explosion-proof electrical devices in the factory need to be tested by external third-party agencies every year? Is this a mandatory requirement? What types of tests need to be done? What electrical equipment is included? Isn’t the quantity too much? Equipment for the electrical field, equipment for the instrumentation field – large items such as motors, and small items such as switch valves, control valves, solenoid valves, flow meters, temperature sensors, pressure sensors, level gauges, and various other types of instruments? There are so many of them – it’s too troublesome. The testing costs must be high as well, but **it isn’t clear what aspects will be tested.**
As for the explosion-proof electrical equipment in the factory, whether it is necessary to have it tested by an external third-party agency every year depends mainly on local safety regulations or the company’s internal safety policies. In many places, to ensure the safe operation of equipment and the safety of personnel, regular safety inspections of explosion-proof electrical devices are required. The items inspected mainly include: explosion-proof structural integrity, electrical parameters, insulation performance, grounding condition, protection rating, and explosion-proof performance. Devices that need to be inspected typically include all electrical equipment that may generate sparks or high temperatures, thereby potentially causing an explosion. This may include equipment from the electrical field, as well as equipment from the instrumentation field; large items such as motors, and smaller items such as switch valves, control valves, solenoid valves, flow meters, temperature sensors, pressure sensors, level gauges, and various other types of instruments. Although the number may be large, the testing process can be cumbersome and the costs can be high, it is done to ensure the safe operation of the equipment and the safety of people’s lives. As for **whether there are clear regulations, it depends on the local laws. It is recommended that you consult the local safety supervision authorities or seek advice from professional third-party inspection agencies, as they will be able to provide you with more specific suggestions and guidance. .
\"Code for Electrical Safety and Explosion Protection in Hazardous Areas\" (AQ 3009-2007) 7.1.3.2 Regular inspections: Regular inspections can be carried out through the visual checks and general inspections specified in Table 10-18. Regular visual inspections or general checks may require further detailed examinations. Regular inspections should be carried out by safety production testing and inspection agencies with specialized expertise in explosion prevention, with an interval generally not exceeding 3 years. Enterprises should take corrective actions promptly based on the inspection results, and file the plant establishment report as well as information on the corrective actions with the work safety supervision and management department. All results of initial, periodic, and continuous monitoring should be recorded.
