How is the location and type of ERZ determined?

• A. SSE must ensure risk assessment is carried out to identify the location and type of each ERZ
• B. Fixed schedule determines ERZ locations
• C. ERZs are identified by random selection
• D. ERZ locations are determined by the mine manager's discretion

Answer: (A)

ERZ locations are defined through a risk assessment led by the Site Senior Executive. This assessment looks at the mine layout, ventilation, escape routes, refuge areas, and plausible emergency scenarios to decide where an ERZ is needed and what type it should be. By tying the ERZ to identified risks, the plan ensures there are safe, ventilated spaces and clear routes for evacuation under real conditions. A fixed schedule, random selection, or discretionary decisions without a risk-based basis would not reliably protect people or meet safety requirements, because they ignore the actual hazards and layout of the mine. So the key is using a thorough risk assessment to determine both where ERZs should be and what form they should take.
