Mobile phones can be used in explosion-proof areas, but professional explosion-proof mobile phones are required
Due to the zoning of hazardous sites in China, the area of combustible vapor is planned as
Landform of Zone 0 with continuous or habitual occurrence of combustible vapor compounds
The landform of combustible vapor compounds will appear in Zone 1 during normal operation
It is unlikely that the landform of combustible vapor compounds will appear in Zone 2 during all normal operations, or even if it appears, the landform of combustible vapor compounds will only exist for a short time
Available area on explosion-proof mobile phones: only installed in hazardous areas of Zone 1 or Zone 2.
Available regions on intrinsically safe mobile 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 Zone 0.
Exib: Industrial equipment that can maintain explosion-proof characteristics until the failure of an electronic component or other types of equipment. Intrinsically safe industrial equipment can be installed in hazardous sites in Zone 1 and Zone 2.
Therefore, in petrochemical and other open places, if explosive gas occasionally occurs, you can choose intrinsically safe explosion-proof mobile phones. Ordinary mobile phones are not shielded, which is easy to generate static electricity and cause danger.
