Mines rescue operations are physically and psychologically demanding and such duties can often be performed in conditions that may not be well tolerated.
Toxic atmospheres and poor ventilation encountered during rescue operations require mine rescue personnel to wear self-contained breathing apparatus (SCBA). This, combined with very physically demanding work such as moving fallen materials and retrieval of casualties, can significantly increase the risk for conditions such as heat stress and/or injury.
To be a mines rescue member requires a high level of health and fitness than compared to normal mining operation roles. Therefore health assessments for mines rescue personnel are designed to assess the health and capacity of the individual to be able to safely perform the mines rescue role.
