Can mobile phones be used in explosion-proof areas?
Mobile phones can be used in explosion-proof areas, but professional explosion-proof mobile phones are required
As China has zoning for hazardous sites, the area planning for combustible vapors is
Zone 0 Topography where combustible vapor compounds appear continuously or habitually
Zone 1 The terrain and landforms of combustible vapor compounds will appear when everything is in normal operation
Zone 2 It is unlikely that the topography of combustible vapor compounds will appear during normal operation, or the topography of combustible vapor compounds that only exist for a short time even if it appears
Available areas on explosion-proof mobile phones: Only installed in hazardous locations in Zone 1 or Zone 2.
Available areas on intrinsically safe phones:
Exia: Industrial equipment that can maintain explosion-proof characteristics until two electronic components or other types of equipment fail. Intrinsically safe industrial equipment can be installed in hazardous sites in Zone 0, Zone 1, and Zone 2. Exia intrinsically safe industrial equipment is the only explosion-proof electrical equipment that can be installed in 0 areas.
Exib: Industrial equipment that can maintain explosion-proof characteristics until an electronic component or other types of equipment fail. Intrinsically safe industrial equipment can be installed in hazardous sites in Zone 1 and Zone 2.
Therefore, in non-enclosed places such as petrochemical industry, where explosive gas occasionally occurs, you can choose an intrinsically safe explosion-proof mobile phone. Ordinary mobile phones are not shielded, which is prone to static electricity and danger.
