Illustration of ignition in a chemical company
On September 21, 2019, at 9:00 a.m., when the outside construction unit overhauled the paraffin workshop of a company's alkali plant, an electrostatic fire broke out, inadvertently ignited the empty resin barrel stored on the spot, and the employees of the branch company put out the fire at 9:08 a.m. No casualties or major property losses were caused.

As we all know, some special jobs need to carry special appliances, even mobile phones. Recently, a fire broke out in a chemical company, and suspected workers did not use explosion-proof mobile phones to generate static electricity to spark, inadvertently igniting the empty resin barrels stored on the scene!
In the use of ordinary mobile phones, because of high-frequency electromagnetic waves, there will be radio frequency sparks, friction sparks, sparks generated by the device itself and battery explosion, and other risk factors, which become the source of ignition. Because explosive mixtures are ubiquitous in coal, petroleum, chemical industry, textile, food processing, and other industries in the production, processing, storage and transportation of places, ordinary mobile phones in these places become a very strong source of safety accidents, such as explosion is extremely harmful; Explosion-proof mobile phone fundamentally solves the problem of ignition source. The appearance of an explosion-proof mobile phone is not different from that of ordinary mobile phones, but it's material and physical characteristics are quite different from those of ordinary mobile phone. Manufacturers use a variety of explosion-proof technologies, such as intrinsic safety circuits, limiting the maximum surface temperature of the case, and using "dust-tight" or "dust-proof" case to limit dust entry, to prevent the ignition of explosive mixtures, so that explosion-proof mobile phones can be safely used in the above dangerous environment. Explosion-proof mobile phones refer to mobile phones used in different flammable, explosive and dust environments according to different explosion-proof certification levels. Ex explosion-proof certification marks are attached to all explosion-proof mobile phones, indicating that the product has passed the national explosion-proof testing agency certification, and can be used in a specific explosive gas environment.

Taking CONQUEST S8 mine intrinsically safe mobile phone as an example, the mine explosion-proof sign of CONQUEST S8 mine intrinsically safe mobile phone is Ex IB I Mb. In addition, it also has an intrinsically safe explosion-proof certification. That is to say, the dual explosion-proof certification of coal mine and intrinsically safe is not only mine explosion-proof mobile phone, but also intrinsically safe explosion-proof mobile phone. Mobile phone. CONQUEST S8 uses the Android 7.1.1 system, CPU is 8-core 2.6 GHz, memory can be CONQUEST in 4 GB + 64 GB, 6 G + 128G two forms, fast operation, large storage space, can meet the long-term use ofCONQUEST coal mines. Coal productionCONQUEST operation, working area is small, smoky and humid, and often accompanied by the threat of water, fire, gas and other accidents. Conquer (CONQUEST) S8 mine intrinsically safe mobile phone protection level is IP68, waterproof, shockproof, dust-proof after intrinsically safe technical treatment, can be in methane mixture and coal dust explosion dangerous coal mine.CONQUEST use. Safety inspection of coal mine production is particularly important, which requires conquest mine to take on-site photographs and evidence, integrate and sort out the three violations and hidden dangers, realize real-time transmission, analysis, and evaluation, make conquest working records and safety inspection more rapid and transparent, CONQUEST S8 has a 5-inch FHD display screen, double cards waiting. Supporting all Netcom 4G, with 8 million, 13 million high-definition cameras, suitable for conquest high-definition photography.
