Shenzhen Zhongnuo Testing Technology Co., Ltd. offers on-site explosion-proof electrical inspection, explosion-proof project acceptance services, and can provide explosion-proof rectification and construction services for items that fail inspection.
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 checked regularly? How often should a check report be issued? What standards are explicitly stated, and how are they defined? These are questions that many industrial clients with explosive hazards in chemical, grain and oil, and gas station sectors 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 valid explosion-proof certification, and ensure proper installation and maintenance. In addition, regular explosion-proof safety checks and routine inspections and maintenance of these electrical devices are required to confirm their continued explosion-proof performance. AQ3009-2007 "Safety Code for Electrical Explosion Protection in Hazardous Areas" also stipulates that periodic inspections should be conducted by safety production inspection and testing institutions with explosion-proof qualifications, with intervals generally not exceeding three years.
ZhongNuo Inspection has provided on-site explosion-proof inspections and modification construction 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. Inspection items include the selection, installation, wiring, static electricity, grounding, and more of explosion-proof equipment. Inspection methods include visual inspections, general inspections, and detailed inspections. This inspection must be conducted on-site, requiring the customer to provide information such as the area of the explosion-proof zone, the number of electrical equipment, and the MSDS of the site. Following the on-site inspection, 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.

Standards and cycles for regular inspections of explosion-proof electrical equipment
With the increasing popularity of explosion-proof electrical equipment, many explosive hazard sites have installed and utilized explosion-proof electrical appliances.
Many end-users believe that installing explosion-proof electrical equipment in explosive hazardous areas is all that's needed.
In many cases, so-called explosion-proof electrical equipment lacks a valid explosion-proof certificate, or the certificate has expired or is counterfeit. The label does not match the explosion-proof certificate.
Selection of explosion-proof type is incorrect, mixing of gas explosion-proof electrical equipment and dust explosion-proof electrical equipment, improper wiring of explosion-proof electrical equipment installation, circuit not grounded.
Holes in explosion-proof casings and button installations can cause explosion-proof failure. Long-term exposure to corrosion, high temperatures, and intense vibrations can also lead to failure in explosion-proof electrical equipment.
For explosion-proof electrical equipment in use, the AQ 3009-2007 "Electrical Safety and Explosion-Proof Regulations for Hazardous Areas" standard stipulates:
Electrical equipment used in explosion-proof environments should be inspected by a certified explosion-proof specialist center at least every 3 years to check its performance, installation, maintenance, etc.
Immediate corrective actions must be taken for non-compliance items, and the inspection report and the rectification status must be filed with the Safety Production Supervision and Administration Department.
Conducting on-site explosion-proof inspections for electrical equipment in use is not only a requirement of the safety production department, but also a testament to the company's emphasis on its own life and property safety.

What qualifications are required for regular inspections of explosion-proof electrical equipment?
The periodic inspection of explosion-proof electrical equipment, as mentioned in the above text, in accordance with the AQ 3009-2007 "Electrical Safety and Explosion Proof Standard for Hazardous Areas," must be conducted by a certification center with explosion-proof professional qualifications. This qualification is authorized by the CNAS (China National Accreditation Service for Conformity Assessment) and can be verified on the CNAS website.
