Under Sch3 Reg 22, which item has a 1 Month timeframe?

• A. Sealing.
• B. Inrush Zone.
• C. Roadway >5.5.
• D. Explosives (not used prior).

Answer: (A)

Under Sch3 Reg 22, safety actions are assigned specific timeframes. Sealing is the one that must be completed within one month. This reflects its role in isolating a part of the mine to prevent gas migration or fire spread, while still allowing adequate time to plan and carry out the work safely. The other items relate to hazards or design criteria that do not carry a one-month deadline—an inrush zone requires immediate controls, a roadway dimension is a design specification, and explosives handling is governed by its own procedures. So sealing is the item with the 1-month timeframe.
