Do explosion-proof areas require regular inspections? Which standard stipulates this?
In areas posing explosive hazards, the installation and use of explosion-proof equipment is a basic requirement. Additionally, stringent explosion-proof requirements must be met for wiring, grounding, ventilation, wall penetration, explosion relief, and anti-explosion measures in such locations.
Do these locations require regular inspections?
Yes. According to the AQ 3009-2007 "Electrical Safety and Explosion Proof Regulations for Hazardous Areas," in addition to daily inspections, these sites must undergo regular explosion-proof checks by a qualified third-party organization to ensure safety.

Do you need to conduct an explosion-proof electrical inspection and acceptance report after the construction site is explosion-proofed? What standards are followed?
The explosion-proof performance of explosion-proof products is not only about the equipment itself but also involves the equipment selection, installation methods, on-site wiring, and daily maintenance and upkeep practices.
Improper selection and installation of explosion-proof equipment, non-compliant site wiring with standard requirements, and daily maintenance that damages the equipment's explosion-proof performance can all lead to the loss of the equipment's explosion-proof characteristics, 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 other standards, with a corresponding explosion-proof electrical inspection report issued.
After the explosion-proof equipment installation and acceptance, it's not a one-time task. To ensure the equipment operates effectively and can be safely used in hazardous areas over the long term, continuous supervision and regular inspections of the in-use explosion-proof equipment are mandatory.
The interval for regular inspections is generally not more than 3 years.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspections and explosion-proof renovation services for various gas stations, fuel stations, oil depots, food factories, feed factories, chemical plants, etc., boasting a wealth of successful cases and industry experience.
If you happen to need a report on explosion-proof electrical inspections for such on-site work, feel free to message us for detailed discussion.

After the explosion-proof project is completed, it requires a third-party institution with explosion-proof inspection qualifications (Shenzhen ZhongNuo Inspection Technology Co., Ltd.) to conduct the project acceptance. The project can only be put into use after passing the acceptance.
Safety explosion-proof project acceptance content
1. The label of explosion-proof electrical equipment must include the explosion-proof qualification number issued by the inspection unit.
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 of 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. Ventilation and exhaust systems of positive-pressure electrical equipment should be unobstructed, correctly connected, and the installation positions of intake and outlet meet the requirements.
5. Excess entry ports of electrical equipment should be sealed properly as per regulations.
6. The installation of sealed devices in electrical circuits should comply with regulations.
7. The wiring engineering of inherently safe electrical equipment shall comply with the design for the routing and elevation of the lines; the lines should be marked with a sky blue sign.
8. The grounding or neutral connection of electrical equipment, as well as static-dissipative wiring, should meet design requirements and ensure a firm and reliable grounding.
