Air enriched with methane from mine gas and coal dust can lead to extremely violent explosions if ignited. Therefore, the methane content in the atmosphere of mines is constantly monitored.
Telephones, smartphones and tablets are practical tools for organizing remedial actions when the monitoring system reports exceeding the limit values. To ensure that the means of communication does not become a source of ignition in this case, it must meet clearly defined requirements. M1 category devices are characterized by a very high level of security.
