How often should explosion-proof electrical equipment be regularly inspected?
With the widespread use of explosion-proof electrical equipment, many explosive hazardous areas have adopted such equipment. Many end-users believe that installing explosion-proof electrical equipment in hazardous areas is sufficient. However, in many cases, the so-called explosion-proof equipment lacks valid certification, has expired or is counterfeit, the label does not match the certification, the type selection does not comply with standards, gas and dust explosion-proof equipment are mixed, holes are drilled in explosion-proof enclosures, and explosion-proof equipment is subjected to long-term corrosion, high temperatures, and intense vibrations. Regarding explosion-proof electrical equipment in use, 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 certified center with explosion-proof expertise at least every 3 years for performance, installation, and maintenance. Necessary corrective actions must be taken for any non-compliance, and the inspection report and corrective measures must be filed with the safety supervision and management department. Conducting on-site explosion-proof inspections of electrical equipment in use is not only a requirement of the safety department but also a reflection of the 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, oil depots, food factories, feed mills, and chemical plants, boasting a wealth of successful cases and industry experience.

Do you need to conduct an explosion-proof electrical inspection and acceptance report after the explosion-proof construction site work? 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-compliance with standard wiring requirements on-site, and daily maintenance damage that compromises the explosion-proof performance of equipment 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 primarily based on AQ 3009, GB/T3836.15, GB/T3836.16, GB 50257, GB 50058, and others, along with the issuance of an explosion-proof electrical inspection report.
After the installation and acceptance of explosion-proof equipment, it's not a one-time task. To ensure the equipment operates effectively and can be used safely in hazardous areas for the long term, 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.
ZheNuo Inspection has provided on-site explosion-proof electrical inspections and explosion-proof transformation construction services for various gas stations, oil stations, oil depots, food factories, feed mills, chemical plants, etc., with a large number of successful cases and industry experience.
