QUESTION 1
1.1 Key Failures Leading to Exposure
The following critical failures contributed to the mine workers' exposure to respirable
silica dust and heat stress:
1. Malfunctioning Dust Suppression Systems: The water spray and misting
systems—essential for controlling dust at the drilling face—were not functioning
properly, allowing silica dust to become airborne.
2. Ineffective Ventilation: The underground ventilation system was
underperforming due to delayed servicing. This limited the removal of airborne
contaminants and heat.
3. Lack of Maintenance: Delayed servicing and poor maintenance of dust
suppression and ventilation systems show a failure in preventative maintenance
planning. Terms of use
