Regular inspection standards and cycles for explosion-proof electrical equipment
With the increasing popularity of explosion-proof electrical equipment, many explosive hazardous areas have installed and utilized explosion-proof electrical appliances.
Many end-users believe that as long as explosion-proof electrical equipment is installed in hazardous explosive areas, everything is settled.
In many cases, so-called explosion-proof electrical appliances do not have an explosion-proof certification, or the certification is expired or fraudulent, with the label not matching the certification.
Inadequate selection of explosion-proof types, misuse of gas explosion-proof electrical equipment and dust explosion-proof electrical equipment, improper wiring of explosion-proof electrical installations, lack of grounding of the circuit.
Holes are drilled and buttons are installed on explosion-proof casings, causing explosion-proof failure. Explosion-proof electrical equipment is subject to long-term corrosion, high temperatures, and intense vibrations.
For explosion-proof electrical equipment in use, the AQ 3009-2007 "Electrical Safety and Explosion-Proof Regulations for Hazardous Areas" standard stipulates:
Electrical equipment with explosion-proof ratings should be inspected at least once every 3 years by a certified explosion-proof inspection center for its performance, installation, and maintenance, etc.
Immediate corrective actions must be taken for non-conformities found during inspections, and the inspection report and the corrective measures must be filed with the Safety Production Supervision and Management Department.
Conducting explosion-proof field inspections on in-service explosion-proof electrical equipment is not only a requirement of the safety production department, but also a reflection of the company's emphasis on its own life and property safety.

How often should explosion-proof electrical equipment be inspected? How to apply for an explosion-proof electrical inspection report?
Should explosion-proof electrical equipment in use be inspected regularly? How often should a check report be generated? What standards are explicitly mentioned, and how are they defined? These are questions that many clients with explosive hazards in industries like chemicals, grain and oil, and gas stations are eager to know. China Nu Inspection will simply answer these questions for you.
Due to the industry's特殊性, facilities with explosive hazards must purchase and install equipment with a legitimate explosion-proof certification and ensure proper installation and maintenance. In addition, regular explosion-proof safety performance checks, as well as daily inspections and maintenance, must be conducted on these electrical devices to confirm their continued explosion-proof capabilities. AQ3009-2007 "Electrical Explosion-Proof Safety Code for Hazardous Areas" also stipulates that regular inspections should be entrusted to explosion-proof qualified safety production inspection and testing agencies, with intervals generally not exceeding 3 years.
ZhongNuo Inspection has provided on-site explosion-proof inspections and改造 services for various gas stations, gas stations, oil depots, food factories, feed factories, chemical plants, etc., with a wealth of successful cases and industry experience.

How to conduct explosion-proof safety inspections for electrical equipment in use?
In accordance with the AQ3009-2007 "Electrical Explosion-Proof Safety Regulations for Hazardous Areas," explosion-proof electrical equipment in use must undergo a periodic explosion-proof inspection at least every 3 years to ensure their explosion-proof performance. The inspection items include the selection, installation, wiring, static electricity, grounding, and more of the explosion-proof equipment. The inspection methods include visual inspection, general inspection, and detailed inspection. This requires on-site checks at the customer's location, where the customer must provide information on the area of the explosion-proof zone, the number of electrical equipment, and the MSDS for the site. After the on-site inspection is completed, a report with explosion-proof improvement suggestions or an explosion-proof inspection report will be issued based on the actual situation.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspection services for various facilities such as gas stations, oil depots, food factories, feed mills, chemical plants, and more. We also offer explosion-proof整改 and construction services for non-compliant items identified during on-site inspections, with a wealth of successful cases and industry experience. If you need to prepare an explosion-proof electrical inspection report for on-site requirements, feel free to message us for detailed communication.
