Management of self-contained self-rescuers in mines

ANNEXURE 2: Guidance Note 2 (mandatory) Leak testing (for lamp-rooms only)

The following criteria must be implemented:

 Leak testing must meet the requirements of SANS 1737 .

 Leak test shall adhere to a series of physical performance and basic specifications.

 A benchmark must be set stipulating minimum pressure measurements and standard evacuation times.

Leak test parameters:

 For shallow mining (i.e. mines less than 500m in depth, e.g. coal mines)

Test pressure = -70mbar or -7000Pa or -7kpa or -0.07bar

 For deep mining (i.e. mines deeper than 500m in depth, e.g. gold and some platinum mines)

Test pressure = -200mbar or -20000Pa or -20kpa or -0.2bar

Leak test intervals should be indicated, based on risk assessment, but should be performed at least bi-annually.
