Is a explosion-proof electrical equipment inspection required after installation?
Many corporate customers are puzzled: Does the installation of electrical equipment with a valid and authentic explosion-proof certification mean it can be used normally?
Does using explosion-proof equipment equate to the entire unit being explosion-proof?
We understand that every product has its lifecycle, from production to market launch, end-user usage, wear and tear, and eventually obsolescence. As specialized equipment in a special industry, the lifecycle of explosion-proof devices extends beyond the product itself, encompassing factors such as installation methods and maintenance procedures. In practice, incidents often occur where improper use by the user leads to the failure of explosion-proof electrical equipment, causing explosions. This is a situation that warrants serious caution.
Therefore, the installation and acceptance of the newly introduced explosion-proof equipment is particularly necessary and important.
After the explosion-proof equipment is installed, an initial inspection should be conducted by a qualified inspection agency with explosion-proof inspection资质 prior to transferring the project to the user, to ensure the entire project's explosion-proof safety performance. The explosion-proof acceptance standards are based on mandatory standards such as AQ 3009, GB/T3836.15, GB/T3836.16, GB 50257, etc.
After the explosion-proof equipment installation and acceptance, it is not a one-time task. To ensure the equipment remains in good working condition and can be safely used in hazardous areas over a long term, continuous supervision and regular inspections of the equipment in use are also required.
Continuous supervision should be conducted by the company's personnel, with corresponding inspection records kept, and any abnormal phenomena should be handled promptly.
Regular inspections should be entrusted to qualified inspection agencies, with intervals generally not exceeding 3 years. Enterprises should promptly implement explosion-proof rectification measures for items that do not meet the inspection criteria and file the third-party qualification agency's Report and rectification status with the department of安全生产 supervision and management.

What qualifications are required for regular inspections of explosion-proof electrical equipment?
The regular inspection of explosion-proof electrical equipment, as mentioned in the previous text, in accordance with the AQ 3009-2007 "Electrical Safety Explosion-Proof Standards for Hazardous Areas," must be conducted by a certified inspection center with explosion-proof expertise. This expertise is authorized by the CNAS and can be verified on the CNAS website.

Is a explosion-proof electrical inspection and acceptance report required after the construction on the explosion-proof site? 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 field wiring with standard requirements, and daily maintenance damage that compromise the equipment's explosion-proof properties 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 others, with an explosion-proof electrical inspection report issued.
After the installation and acceptance of explosion-proof equipment, it's not a one-time task. To ensure the explosion-proof equipment remains in good working condition and can be safely used in hazardous areas for an extended period, continuous supervision and regular inspections of the equipment in use are essential.
The interval for regular inspections generally does not exceed 3 years.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspection and explosion-proof transformation construction services for various gas stations, petrol stations, oil depots, food factories, feed factories, chemical plants, etc., with a wealth of successful cases and industry experience.

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