The importance and necessity of on-site explosion-proof inspection

With the increasing popularity of explosion-proof appliances, many explosive hazardous areas have installed and used explosion-proof appliances. Many end users believe that as long as explosion-proof electrical appliances are installed in explosive hazardous areas, everything will be fine. In many cases, so-called explosion-proof electrical appliances do not have explosion-proof certificates, or their explosion-proof certificates have expired or become fake. The nameplate is inconsistent with the explosion-proof certificate, the explosion-proof type selection is not in compliance, gas explosion-proof electrical equipment and dust explosion-proof electrical equipment are mixed, the wiring of explosion-proof electrical appliances is improper, the wiring is not grounded, drilling holes in the explosion-proof shell, installing buttons causes explosion-proof failure, and explosion-proof electrical appliances are subjected to long-term corrosion and high temperatures Intense vibrations, etc.

For explosion-proof electrical appliances in use,AQ 3009-2007The "Code for Electrical Safety and Explosion Protection in Hazardous Areas" standard stipulates that explosion-proof electrical appliances in use shall be at least3Entrust a testing center with explosion-proof professional qualifications once a year to conduct performance, installation, maintenance, and other tests on explosion-proof electrical appliances. For any non conformities detected, corrective measures must be taken in a timely manner, and the inspection report and rectification situation must be filed with the safety production supervision and management department.

Conducting explosion-proof on-site inspections on explosion-proof electrical appliances in use is not only a requirement of the safety production department, but also a concern of the enterprise for its own life and property safety.
