Do explosion-proof areas require regular inspections? Which standard specifies this?
In areas with explosive hazards, the installation and use of explosion-proof equipment is a fundamental requirement. In addition, strict explosion-proof requirements must be met for wiring, grounding, ventilation, wall penetration, explosion relief, and anti-explosion measures in such locations.
Do such 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 inspections by a qualified third-party organization to ensure safety.

ZhongNuo Inspection's on-site explosion-proof inspection service scope:
Explosive gas environments and hazardous areas with flammable or combustible dust in industries such as oil, chemicals, coal, shipping, ports, marine engineering, gas engineering, pharmaceuticals, machinery, textiles, electricity, light industry, grain processing and storage, and timber processing must ensure explosion-proof safety for dangerous areas. This safeguards against explosions and supports the economic development of our country.

Do you need to conduct a 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 equipment, installation methods, on-site wiring, and daily maintenance and care techniques.
Improper selection and installation of explosion-proof equipment, non-compliant field wiring with standard requirements, and daily maintenance that damages the equipment's explosion-proof properties can all lead to the loss of the equipment's explosion-proof capability, 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, and a explosion-proof electrical inspection report is provided.
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 safely used in hazardous areas over 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.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspections and explosion-proof renovation services for various gas stations, gas stations, oil depots, food factories, feed mills, chemical factories, etc., with a wealth of successful cases and industry experience.
