- Support loose roof and rib material adequately or scale loose material from a safe location before working or travelling in an area.
- Examine the roof, face and ribs immediately before starting work in an area and throughout the shift as conditions warrant.
- Take additional safety precautions when mining heights increase and in areas where mine conditions change.
- Train miners to recognise roof and rib hazards and to stop work in the area until the hazards are corrected.
