Breathing Air Cascade Systems and Self Contained Breathing Apparatus (SCBA)

Cascade systems are deployed to ensure personnel at risk from exposure to H2S have available a safe and reliable supply of breathable air. Outlet manifolds and plug-in points are located in critical areas and these allow workers who may have to continue critical operations – such as emergency well control – to continue working for an extended period beyond that available using Self Contained Breathing Apparatus (SCBA) normally 30 minutes. The use of a cascade system ensures that the essential crew have breathable air available during and beyond the expected duration of the operation thus ensuring the safe completion of the work required.
