Do explosion-proof areas require regular inspections? Which standard stipulates this?
Installation and use of explosion-proof equipment is a basic requirement in explosive hazard zones. Additionally, stringent explosion-proof requirements must be met for wiring, grounding, ventilation, wall penetration, and explosion venting in such areas.
Do such places require regular inspections?
Yes. According to the AQ 3009-2007 "Electrical Safety and Explosion Proof Specifications for Hazardous Locations," in addition to routine inspections, these locations must undergo regular explosion-proof checks by a qualified third-party institution to ensure safety.

Do you need to conduct an explosion-proof electrical inspection and acceptance report after the 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 selection of the equipment, installation methods, on-site wiring, and daily maintenance and care practices.
Improper selection and installation of explosion-proof equipment, non-compliant site wiring with standard requirements, and daily maintenance that damages the explosion-proof performance of equipment can all lead to the loss of explosion-proof properties, posing a risk of explosion.
Therefore, the installation and acceptance inspection 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 other standards, with an explosion-proof electrical inspection report provided.
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 necessary.
The interval for regular inspections generally does not exceed 3 years.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspections and explosion-proof retrofitting construction services for various gas stations, oil stations, oil depots, food factories, feed factories, chemical plants, etc., with a large number of successful cases and industry experience.
If you happen to need a防爆电气检查报告 for such on-site requirements, feel free to send us a private message for detailed discussion.

After completion of the explosion-proof project, it is required for a third-party institution with explosion-proof inspection qualifications (Shenzhen ZhongNuo Testing Technology Co., Ltd.) to conduct project acceptance. Only after passing the acceptance can the project be put into use.
Explosion-proof project acceptance content
1. The explosion-proof certificate number issued by the inspection unit must be marked on the label of explosion-proof electrical equipment.
2. The types, levels, and groups of explosion-proof electrical equipment should comply with the design.
3. The housing of explosion-proof electrical equipment should be free from cracks or damage; the paint should be intact. The cover of the junction box should be tightly secured, and the fixing bolts and anti-loosening devices should be in place.
4. The ventilation and exhaust systems of positive pressure electrical equipment should be unobstructed, correctly connected, and the import and export installation positions should meet the requirements.
5. Excess entry ports of electrical equipment should be properly sealed in accordance with regulations.
6. The installation of sealed devices in electrical circuits should comply with regulations.
7. The wiring engineering for inherently safe electrical equipment should comply with the design for its routing and elevation; the lines should be marked with a sky blue sign.
8. The grounding or neutral connection of electrical installations, as well as antistatic wiring, must comply with design requirements and ensure firm and reliable grounding.
