UPSC CISF-AC-EXE – 2024
CISF provides fire coverage to various industrial establishments including power plants, oil refineries, and fertilizer plants, which were traditionally public sector undertakings or critical infrastructure. Coal mines, while industrial establishments, typically fall under specific mining safety regulations and often have their own dedicated mine rescue and fire fighting services due to the unique and hazardous environment of mining operations, including risks of gas explosions and underground fires. Thus, coal mines are generally an exception to the establishments covered by the CISF Fire Wing.
CISF Fire Wing primarily covers specified industrial units, but coal mines often have separate, specialized safety and fire protocols and services.
The Directorate General of Mines Safety (DGMS) governs safety in mines, and mine rescue stations and dedicated fire services are mandated for coal mines, reflecting the highly specialized nature of fire fighting and rescue in underground environments.
