According to Section 7 of AQ3009-2007 "Safety Code for Electrical Explosion Protection in Hazardous Areas" (implemented on January 1, 2008), electrical equipment used in hazardous areas should undergo initial and regular inspections. The inspection needs to be entrusted to an inspection and testing institution with explosion-proof professional qualifications, and the time interval is generally not more than 3 years. Enterprises should take timely corrective measures based on the inspection results and file the inspection report and rectification situation with the safety production supervision and management department.

So, how do chemical companies conduct on-site explosion-proof electrical testing? Today, Jiangsu Guobin, an explosion-proof electrical testing company, will give you a brief introduction.

Firstly, we need to choose an inspection and testing institution with explosion-proof professional qualifications (you can compare several online or introduce them through acquaintances), then have a meeting to see the scene, and finally the institution will follow the following process for specific operations:

Service process for explosion-proof electrical testing
1. The enterprise provides us with the area of the explosion-proof site and the quantity of explosion-proof electrical products for evaluation and quotation.
2. Formally sign a cooperation agreement, and the enterprise provides detailed information on the explosion-proof site
3. Enterprises conducting on-site explosion-proof inspections are required to provide the following information:
(1) The area of the explosion-proof site;
(2) Classification map of explosion hazardous areas;
(3) The names and safety data sheets (MSDS) of explosive hazardous substances in the corresponding hazardous areas
(4) List of explosion-proof electrical products in use, including information such as installation area and tag number
(5) Copy of explosion-proof certificate for each explosion-proof electrical product
(6) Explanatory document on special operating conditions for explosion-proof electrical equipment
(7) Descriptive technical documents for intrinsic safety systems
(8) Relevant information on installation quality
4. Engineers go to the site to inspect explosion-proof electrical products and issue rectification opinions for non conformities
5. Enterprises cooperate with rectification within the predetermined period according to the rectification opinions
6. The engineer conducts another on-site evaluation and issues an on-site inspection report after passing the evaluation
7. The enterprise shall provide the final inspection report to the local safety supervision department for filing.
