How should hazardous chemical substances be managed in a coal mine?

• A. Store chemicals in any accessible area and label later when needed.
• B. Train workers but do not provide Safety Data Sheets.
• C. Proper storage, labeling, access to SDS, training, spill kits, and safe handling procedures.
• D. Spill kits only; ignore labeling.

Answer: (C)

Hazardous chemical management in a coal mine hinges on a coordinated set of controls that cover storage, labeling, access to Safety Data Sheets, worker training, spill response equipment, and safe handling procedures. This approach ensures chemical hazards are identified and communicated, information about risks and first aid is readily available to workers, and the right controls are in place to prevent releases and exposures. The Safety Data Sheet provides details on hazards, storage and handling guidelines, PPE, and emergency measures; labeling gives immediate recognition of the substance and its hazards; proper storage prevents incompatible combinations and leaks; training equips workers to handle, use, and store chemicals safely; spill kits enable rapid containment and cleanup; and safe handling procedures guide transfers, use, and disposal. The other options fall short because they omit essential elements or promote unsafe practices: storing chemicals in an accessible area and labeling later fails to communicate hazards; training without SDS leaves crucial information inaccessible; relying only on spill kits ignores prevention and labeling for ongoing safety.
