Does explosion-proof electrical equipment require an explosion-proof acceptance test after installation?
Many corporate clients are puzzled: Does the installation of electrical equipment with a valid and authentic explosion-proof certification mean it can be used normally?
Is using explosion-proof equipment equivalent to the entire system being explosion-proof?
We understand that each product has its lifecycle, from production, market launch, end-user use, wear and tear, to obsolescence. As special equipment in a specialized industry, the lifecycle of explosion-proof equipment isn't just about the product itself; it also involves aspects like installation methods and maintenance procedures. In reality, explosions often occur due to improper use of explosion-proof electrical equipment, leading to accidents. This is something that warrants our utmost vigilance.
Therefore, the installation and acceptance of the newly introduced explosion-proof equipment is particularly necessary and important.
After the explosion-proof equipment is installed, an initial inspection should be conducted by a qualified inspection agency with explosion-proof inspection资质 prior to transferring the project to the user, to ensure the entire project's explosion-proof safety performance. The explosion-proof acceptance standards are based on mandatory standards such as AQ 3009, GB/T3836.15, GB/T3836.16, GB 50257, etc.
After the installation and acceptance of explosion-proof equipment, it is not a one-time task. To ensure the equipment operates effectively and can be safely used in hazardous areas for the long term, continuous supervision and regular inspections of the in-use explosion-proof equipment are necessary.
Continuous supervision should be carried out by the company's personnel, with corresponding inspection records kept, and abnormal phenomena addressed promptly.
Regular inspections should be entrusted to qualified inspection agencies, with intervals generally not exceeding 3 years. Enterprises should promptly implement explosion-proof rectification measures for items that do not meet inspection standards and file the third-party qualification agency's Report and rectification status with the department of安全生产 supervision and management.

How often is it required to perform periodic inspections on explosion-proof electrical equipment?
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, has expired or counterfeit certificates, mismatched labels with certification, 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 specialized inspection center with explosion-proof qualifications at least once every 3 years for performance, installation, and maintenance. Immediate corrective actions must be taken for any non-compliance, and the inspection report and rectification details 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 a company's commitment to its own life and property safety.
ZhongNuo Inspection has provided on-site explosion-proof inspections and transformation services for various facilities such as gas stations, fuel depots, food factories, feed factories, and chemical plants, with a wealth of successful cases and industry experience.

Shenzhen Zhongnuo Testing Technology Co., Ltd. summarizes the past experience in explosion-proof electrical inspection, the main items and contents of AQ3009 explosion-proof electrical inspection:
In accordance with Section 7 of AQ3009-2007 "Electrical Explosion Protection Safety Regulations for Hazardous Areas" (implemented as of January 1, 2008): Electrical equipment used in hazardous areas shall undergo initial and periodic inspections. These inspections must be conducted by a qualified explosion-proof inspection agency, with intervals generally not exceeding 3 years. Enterprises should take corrective actions based on inspection results in a timely manner and file the Report and rectification details with the department of安全生产 supervision and management.
The "AQ 3009-2007 Specification for Electrical Safety and Explosion-Proof Protection in Hazardous Areas" is a Chinese industry standard, with the preface explicitly stating that Chapters 4, 5, 6, and 7 are mandatory and must be strictly enforced. Therefore, similar safety specifications also constitute part of the legal regulations and must be strictly enforced!
