Shenzhen ZhongNuo Inspection Technology Co., Ltd. offers on-site explosion-proof electrical inspection, explosion-proof project acceptance services, and consulting services. We also provide explosion-proof rectification and construction services for items that fail inspection.
ZhongNuo Inspection's on-site explosion-proof inspection service scope:
Including industries such as oil, chemicals, coal, ships, ports, marine engineering, gas engineering, pharmaceuticals, machinery, textiles, electricity, light industry, grain processing and storage, and wood processing, where explosive gas environments or environments with explosive or flammable dust exist, it is crucial to ensure explosion-proof safety in hazardous areas. This safeguards the prevention of dangerous explosions and supports the economic development of our country.

Is a explosion-proof equipment acceptance test required after installation?
Many corporate clients are puzzled: Does the installation of electrical equipment with a valid and authentic explosion-proof certification mean it can be used normally?
Is the use of explosion-proof equipment equivalent to overall explosion-proof?
We understand that every product has its lifecycle, from production, market launch, end-user use, wear and tear, to obsolescence. As special equipment in a specialized industry, the lifecycle of explosion-proof equipment is not only about the product itself but also its installation method, maintenance, and care. In reality, there are often cases where improper use by the user leads to the failure of explosion-proof electrical equipment, causing explosion accidents, which is something to be vigilant about.
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 explosion-proof inspection agency before 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's 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 carried out by the company's personnel, and corresponding inspection records should be kept. 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 inspection requirements and file the third-party qualification agency's report and rectification status with the安全生产监督管理部门.

AQ3009 "Electrical Explosion-Proof Safety Regulations for Hazardous Areas" stipulates that regular inspections of hazardous areas should be entrusted to safety production inspection agencies with explosion-proof qualifications, with intervals 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 areas, flammable gas, and other safety facilities and equipment inspections. 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 safeguarding the safety production of enterprises producing hazardous chemicals and those with explosive hazard areas.

How to conduct explosion-proof safety inspections on in-use explosion-proof electrical equipment?
In accordance with the AQ3009-2007 "Electrical Explosion Protection Safety Regulations for Hazardous Areas," explosion-proof electrical equipment in use must undergo a periodic 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 the explosion-proof equipment. The inspection methods include visual inspection, general inspection, and detailed inspection. This inspection must be conducted on-site, and the client is required to 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 with explosion-proof improvement suggestions 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, petrol stations, oil depots, food factories, feed mills, chemical plants, and more. We also offer explosion-proof correction and construction services for non-compliant items identified during on-site inspections, with a wealth of successful cases and industry experience. If you need to conduct an on-site explosion-proof electrical inspection report, feel free to send us a private message for specific communication.
