Why you need spark-proof equipment
Explosion hazards occur when air, combustible dusts/gases, and active ignition sources are combined. Ignition sources can be fire, flames, heat, spark, arc and smoldering electrical discharges sparks from mechanical impact, sparks produced by electrical equipment, etc.
There is a high risk of explosive atmospheres where flammable materials are handled: crude oil and refined products, alcohols, natural and synthetic technical gases, metal dust, etc., e.g. in petrochemical and chemical plants. oil and gas industry и extractive industries.
In such plants it is necessary to use intrinsically safe devices that operate without potentially generating a source of combustion. Such equipment uses various types of protection to reduce the risk of explosion.
Classification of explosive zones by gas:
| Zone 0 | Zone 1 | Zone 2 |
| An explosive gas mixture is present continuously or for long periods of time. | There is a possibility that an explosive gas mixture may be present under normal operating conditions. | An explosive gas mixture is unlikely to be present under normal operating conditions, if it occurs it is rare and exists for a very short time. |

Classification of explosion hazardous areas by dust:
| Zone 20 | Zone 21 | Zone 22 |
| Combustible dust in the form of a cloud is present continuously or partially during normal operation of the equipment in an amount capable of producing a concentration sufficient to produce an explosion of combustible or flammable dust in mixtures with air, and/or where dust layers of arbitrary or excessive thickness may be formed. | An area, not classified as a Class 20 area, in which combustible dust in cloud form cannot be present during normal operation of the equipment in an amount capable of producing a concentration sufficient to produce an explosion of combustible dust in mixtures with air. | The zone is not classified as zone 21. Combustible dust clouds in this zone are rare and persist only for a short period of time, or the accumulation of combustible dust layers occurs under abnormal operating conditions. If, based on abnormal conditions, the elimination of dust accumulations or layers cannot be guaranteed, then the zone is classified as a Class 21 zone. |

MIG equipment for use in hazardous areas
For the work of mobile personnel in hazardous areas Mobile Inform Group has developed industrial explosion-protected MIG S6 smartphones and MIG T8X tablets (based on architectures x86 and ARM). Smartphones and tablets are suitable for use in potentially explosive areas 1 and 2, categories IIA, IIB and IIC of temperature class T4, as well as in areas hazardous for ignition of combustible dust of classes 21 and 22 in environments of subgroups IIIA, IIIB and IIIC.
Explosion-proof smartphone MIG S6 Explosion-proof tablet MIG T8X
The intrinsic safety of MIG devices is confirmed by certificates of compliance with the requirements of the Technical Regulations of the Customs Union on the safety of equipment for operation in explosive atmospheres.
The explosion safety of MIG S6 smartphones and MIG T8X tablets is ensured by their design: the devices are equipped with a tamper-proof polycarbonate case and a display made of impact-resistant glass with high resistance to scratches and sharp contact damage. To prevent short circuits, a current limiting device with protection tripping is installed on the battery.
The design of smartphones meets the requirements of TR TS 012/2011, general requirements according to GOST 31610.0-2014 (IEC 60079-0: 2011), and type of explosion protection «intrinsically safe electrical circuit «i» according to GOST 31610.11-2014 (IEC 60079-11:2011).
