A Critical Control is a safety measure or barrier specifically identified and implemented to prevent or mitigate the occurrence of a fatal or catastrophic event in mining operations. In bauxite, gold, iron ore, and diamond mining, critical controls are systematically identified through structured risk assessments such as bow-tie analysis or Fatal Risk Management processes. These controls are deemed non-negotiable and are prioritized above all other operational considerations. Examples include lock-out/tag-out procedures for crusher maintenance, exclusion zones around heavy equipment, ground control measures in underground operations, and confined space entry permits. Critical controls are actively verified through regular field checks, management walk-throughs, and control effectiveness reviews. Failure of a critical control typically triggers an immediate work stoppage until the control is restored, reflecting its foundational role in protecting worker safety and asset integrity across all surface and underground mining environments.
