Shenzhen ZhongNuo Inspection & Technology Co., Ltd. offers on-site explosion-proof electrical inspection, explosion-proof project acceptance services, and can also provide explosion-proof rectification and construction services for items not meeting inspection standards.
The "Electrical Explosion Proof Inspection Report" issued from regular inspections of explosion-proof electrical equipment is based on standards including but not limited to:
GB50058-2014 "Code for Design of Electrical Installations in Explosive Hazardous Environments"
GB50257-2014 "Code for Construction and Acceptance of Electrical Installations in Explosive and Flammable Gas Environment"
GB/T3836.15-2017 "Electrical Equipment for Explosive Gas Atmospheres – Part 15: Electrical Installations in Hazardous Areas (Excluding Coal Mines)"
AQ3009-2007 Electrical Explosion Protection Safety Regulations for Hazardous Areas

How often is the regular explosion-proof electrical equipment inspection conducted?
With the widespread use of explosion-proof electrical equipment, many hazardous explosive areas have adopted such devices. Many end-users believe that the installation of explosion-proof electrical equipment in hazardous explosive areas is sufficient to ensure safety. However, in many cases, the so-called explosion-proof equipment lacks proper certification, or the certification is expired or forged, the nameplate does not match the certification, the selection of explosion-proof types is incorrect, gas and dust explosion-proof equipment are used together, holes are drilled in the explosion-proof enclosures, explosion-proof equipment is exposed to long-term corrosion, high temperatures, and intense vibrations. According to AQ 3009-2007 "Electrical Safety and Explosion-proof Regulations for Hazardous Areas" standard, for explosion-proof electrical equipment in use: the performance, installation, and maintenance of such equipment should be inspected by a certified explosion-proof inspection center at least once every 3 years. Immediate corrective actions must be taken for any non-compliance, and the inspection reports and corrective measures must be filed with the safety production supervision and management 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 reflection of the enterprise's emphasis on its own life and property safety.
ZhongNuo Inspection has provided on-site explosion-proof inspections and transformation services for various locations such as gas stations, oil depots, food factories, feed mills, and chemical plants, boasting a substantial number of successful cases and industry experience.

What qualifications are required for regular inspections of explosion-proof electrical equipment?
The regular inspection of explosion-proof electrical equipment, as mentioned in the previous text, in accordance with the AQ 3009-2007 "Electrical Safety and Explosion-Proof Standards for Hazardous Areas," must be conducted by a certified inspection center with explosion-proof expertise. This expertise is authorized by the CNAS through a human commission, and it can be verified on the CNAS website.

Is a explosion-proof electrical inspection and acceptance report required after construction at an explosion-proof site? What standards are followed?
The explosion-proof performance of explosion-proof products is not just about the equipment itself; it also involves the selection of the equipment, installation methods, on-site wiring, and daily maintenance and care practices.
Improper selection and installation of explosion-proof equipment, non-compliance with standard wiring requirements on-site, and daily maintenance damage that compromises the equipment's explosion-proof properties can all lead to the loss of explosion-proof capabilities, posing a risk of explosion.
Therefore, the installation and acceptance of the newly introduced explosion-proof equipment is particularly necessary and important.
The explosion-proof acceptance standards are mainly based on AQ 3009, GB/T3836.15, GB/T3836.16, GB 50257, GB 50058, and other standards, and a explosion-proof electrical inspection report is issued.
After the explosion-proof equipment installation and acceptance, it is not a one-time solution. To ensure that the explosion-proof equipment remains in good operating condition and can be safely used in hazardous areas for the long term, continuous supervision and regular inspections of the equipment in use are also necessary.
The interval for regular inspections is generally no more than 3 years.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspections and explosion-proof renovation services for various gas stations, petrol stations, oil depots, food factories, feed mills, chemical plants, etc., with a wealth of successful cases and industry experience.
