Anglių kasyklų ventiliatoriai privalo turėti anglių saugos sertifikatą

In environments prone to explosions, the use of explosion-proof electrical equipment is imperative, and it must be accompanied by a valid explosion-proof certification. Electrical devices designated for coal mines are required to secure coal mine safety certification prior to deployment underground, a mandate in line with China’s labor safety regulations.

Beyond the coal sector, industries such as petrochemicals, metallurgy, and military manufacturing also rely on explosion-proof electrical equipment to maintain a safe production environment and avert potential explosive incidents.
