Shenzhen Zhongnuo Inspection & Technology Co., Ltd. offers on-site explosion-proof electrical inspection, explosion-proof project acceptance services, and consulting. We also provide explosion-proof rectification and construction services for items that fail inspection.
The "Electrical Explosion Proof Inspection Report" issued from regular inspections of explosion-proof electrical equipment is based on standards including but not limited to:
GB 50058-2014 "Code for Design of Electrical Installations in Explosive Hazardous Environments"
GB50257-2014 Specification for Construction and Acceptance of Electrical Installation Works in Explosive and Flammable Gas and Dust Environments
GB/T3836.15-2017 "Electrical Equipment for Explosive Gas Atmospheres – Part 15: Electrical Installations in Hazardous Areas (Excluding Mines)"
AQ3009-2007 Electrical Explosion-Proof Safety Standard for Hazardous Areas

Do explosion-proof areas require regular inspections? Which standard specifies this?
In areas posing explosive hazards, the installation and use of explosion-proof equipment is a fundamental requirement. Additionally, stringent explosion-proof specifications must be met for wiring, grounding, ventilation, penetration through walls, and explosion venting and resistance.
Do these locations require regular inspections?
Yes. According to the AQ 3009-2007 "Electrical Safety and Explosion-Proof Specification for Hazardous Areas," in addition to daily inspections, these locations must undergo regular explosion-proof checks by a qualified third-party organization to ensure safety.

How often is the periodic inspection for explosion-proof electrical equipment?
With the widespread use of explosion-proof electrical equipment, many explosive hazardous areas have adopted such equipment. Many end-users believe that as long as explosion-proof electrical equipment is installed in hazardous areas, everything is settled. However, in many cases, the so-called explosion-proof equipment lacks a valid explosion-proof certificate, or the certificate has expired or is fake. There are discrepancies between the label and the explosion-proof certificate, incorrect selection of explosion-proof types, mixed use of gas and dust explosion-proof equipment, drilling holes in explosion-proof enclosures, long-term corrosion, high temperatures, and severe vibrations. Regarding the use of explosion-proof electrical equipment, the AQ 3009-2007 "Electrical Safety and Explosion-Proof Regulations for Hazardous Areas" standard stipulates: explosion-proof electrical equipment in use should be inspected by a qualified explosion-proof inspection center at least once every 3 years for its performance, installation, and maintenance, and corrective measures must be taken promptly for any non-compliance. The inspection report and corrective actions must be filed with the安全生产监督管理部门. 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 a 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 checked regularly? How often should a check report be issued? What standards explicitly regulate this, and how are they specified? These are questions many industrial clients with explosive hazards in chemical, grain, oil, and gas stations are eager to know. China Nuotech Inspection provides a simple explanation.
Due to the industry's specificity, locations with explosive hazards must purchase and install equipment with official explosion-proof certification and ensure proper installation and maintenance. In addition, regular explosion-proof safety inspections and daily checks and maintenance of these electrical devices are required to confirm their continued explosion-proof performance. AQ3009-2007 "Electrical Explosion-proof Safety Code for Hazardous Areas" also stipulates that periodic inspections should be entrusted to explosion-proof-qualified safety inspection and testing agencies, with intervals generally not exceeding three years.
