| Уровни защиты оборудования устанавливаются с учетом различных характеристик взрывоопасных газовых сред, взрывоопасных пылевых сред и сред, в которых возможен взрыв угольного метана, а также с учетом вероятности того, что оборудование может стать источником воспламенения. | In explosive gas environments, equipment is designated with a "very high" level of protection, ensuring that it does not serve as an ignition source during regular operation, anticipated malfunctions, or rare failures. | In explosive gas environments, equipment is assigned a "high" level of protection, ensuring that it does not serve as an ignition source during normal operation or anticipated fault conditic ions. | In explosive gas environments, equipment is typically assigned a "general" ievel of protection, preventing it from serving as an ignition source during regular operation. Furthermore, supplementary protective easures can be implemented to minimize the formation of effective ignition sources, particularly in cases of anticipated and frequent occurrences (e.g. failures in lighting fixtures). |

Yet, their usage is permitted during installation, maintenance, or extensive repairs, provided that, as per established procedures, it’s confirmed that these activities do not create conditions conducive to an explosive environment.
