Shenzhen ZhongNuo Testing Technology Co., Ltd. offers on-site explosion-proof electrical inspection, explosion-proof project acceptance services, and consulting. We also provide explosion-proof整改 and construction services for items not meeting inspection standards.
Services for explosion-proof inspections on-site by ZhongNuo Inspection:
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 wood processing must ensure the explosion-proof safety of dangerous explosive sites to safeguard our and the national economy's development.

Does explosion-proof electrical equipment require an explosion-proof acceptance test after installation?
Many corporate clients are puzzled: Does the installation of electrical equipment with a valid and genuine explosion-proof certificate mean it can be used normally?
Is using explosion-proof equipment equivalent to the entire system being explosion-proof?
We understand that each product has its lifecycle, from production, market launch, end-user use, wear and tear to obsolescence. As special equipment in a specific industry, the lifecycle of explosion-proof equipment is not only about the product itself but also its installation method, maintenance, and care. In reality, explosions often occur due to improper use by users, leading to the failure of explosion-proof electrical equipment and causing explosion accidents, which is a matter of great concern.
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 installation and acceptance of explosion-proof equipment, it is not a one-time solution. 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 necessary.
Continuous supervision should be conducted by the company's personnel, with corresponding inspection records kept, and any abnormal phenomena 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 inspection standards and file the third-party qualification agency's Report and rectification status with the安全生产 supervision and management department.

The AQ3009 "Electrical Explosion-Proof Safety Code for Hazardous Places" stipulates that regular inspections of hazardous places should be entrusted to safety production inspection institutions with explosion-proof qualifications, with the interval generally not exceeding 3 years. We offer on-site explosion-proof inspection consulting services, covering electrical explosion-proof safety, static electricity prevention, dust explosion hazard places, flammable gas, and safety inspections of equipment and facilities. We are responsible for explosion-proof equipment design and selection, maintenance and repair of in-use explosion-proof equipment, on-site explosion-proof safety checks in explosive gas environments and flammable dust environments, and ensuring safe production for enterprises producing hazardous chemicals and places with explosion hazards.

How to conduct explosion-proof safety inspections on electrical equipment in use?
In accordance with the AQ3009-2007 "Electrical Explosion Protection Safety Regulations for Hazardous Areas," electrical explosion-proof equipment in use must undergo a regular explosion-proof inspection at least every 3 years to ensure their explosion-proof performance. The inspection items include the selection, installation, wiring, static electricity, grounding, and more of explosion-proof equipment. Inspection methods include visual inspections, general inspections, and detailed inspections. This requires on-site checks, where the customer must provide information such as the area of the explosion-proof zone, the number of electrical equipment, and the MSDS on-site. After the on-site inspection is completed, a report on explosion-proof rectification recommendations or an explosion-proof inspection report will be issued based on the actual situation.
ZhongNuo Inspection has provided on-site explosion-proof electrical inspection services for various gas stations, oil stations, oil depots, food factories, feed mills, chemical plants, and more. We also offer explosion-proof correction and construction services for items that fail on-site explosion-proof inspections, with a wealth of successful cases and industry experience.
