Disclosed are a safety system and method of an underground mine. In one embodiment, a method of safety of a mine structure includes expediting an air extraction process from an emergency support system by including a RIC (rapid interventions company/crew)/UAC (universal air connection) fitting to a fill panel to fill a breathable air apparatus. The method may include ensuring that a prescribed pressure of the emergency support system maintains within a threshold range of the prescribed pressure by including a valve of the emergency support system to prevent leakage of breathable air from the emergency support system. The method may also include maintaining the prescribed pressure of the emergency support system such that a system pressure is compatible with a breathable air apparatus through a distribution structure that is rated for use with compressed air.
