A coal safety certificate is unnecessary unless the equipment and materials are intended for underground applications. For surface use, such certification is not required.
This includes devices like coal cutters, roadheaders, hydraulic supports, single hydraulic props, crushers, belt conveyors, scraper conveyors, hydraulic pump stations, coal drills, air drills, explosion-proof switches, transformers, and local fans. For underground settings, important safety considerations should encompass fire prevention, explosion protection, and resistance to high temperatures.
