Application Requirements for Regular Explosion-Proof Performance Inspections

Shenzhen ZhongNuo Inspection & 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 not meeting inspection standards.
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 include:
In accordance with Section 7 of AQ3009-2007 "Electrical Explosion-Proof Safety Regulations for Hazardous Areas" (implemented as of January 1, 2008): Electrical equipment used in hazardous areas must 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 promptly based on the inspection results and file the Report and the rectification status with the安全生产监督管理 department.
The "AQ 3009-2007 Electrical Safety and Explosion-Proof Standard for Hazardous Areas" serves as a Chinese industry standard. The preface of the standard explicitly states that Chapters 4, 5, 6, and 7 are mandatory and must be strictly enforced. Therefore, similar safety regulations are also part of the legal and regulatory framework, and they must be strictly enforced!

How often is the periodic inspection for explosion-proof electrical equipment conducted?
With the widespread use of explosion-proof electrical equipment, many hazardous explosive areas have adopted such equipment. Many end-users believe that as long as explosion-proof electrical equipment is installed in hazardous explosive areas, everything is settled. However, in many cases, 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, improper selection of explosion-proof types, mixing of gas and dust explosion-proof equipment, drilling holes in explosion-proof enclosures, long-term corrosion, exposure to high temperatures, and severe vibrations. In terms of explosion-proof electrical equipment in use, the AQ 3009-2007 "Safety Requirements for Electrical Installations in Hazardous Areas" standard stipulates that explosion-proof electrical equipment in use should be inspected by a certified explosion-proof inspection center at least once every 3 years for performance, installation, and maintenance. Any non-compliance issues must be addressed promptly, and the inspection report and corrective actions must be filed with the safety supervision and management department. Conducting on-site inspections of explosion-proof equipment in use is not only a requirement of the safety department but also a reflection of the company's concern for its own life and property safety.

Is a explosion-proof electrical inspection and acceptance report required after explosion-proof site construction? What standards are followed?
The explosion-proof performance of explosion-proof products is not just about the equipment itself; it also involves the equipment selection, installation methods, on-site wiring, and daily maintenance and care practices.
Improper selection and installation of explosion-proof equipment, non-compliant site wiring with standards, and daily maintenance damage that compromise the equipment's explosion-proof performance 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, with a corresponding explosion-proof electrical inspection report issued.
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 an extended period, continuous supervision and regular inspections of the in-use explosion-proof equipment are essential.
The interval for regular inspections generally does not exceed 3 years.
