As I was assisting with the pneumatic air start I noticed engine one was running with aircraft [pneumatic] hose underneath the engine. I pointed my finger towards the Lead to let him know about the engine. The lead waved both his hands in the air as if don't worry. As I disconnected the pneumatic air start; the Lead walked over to disconnect the aircraft hose. Within seconds; engine one ingested the aircraft hose.
During a pneumatic air start; a Ramp employee alerts his Ramp Lead that the air hose was lying under Number 1 Engine.  Air hose was ingested by Number 1 Engine after Lead attempted to disconnect the pneumatic hose after the air start was completed.
