IRON, cast iron is different from most anything anybody sees or has seen nowadays.The good thing about the D424A, 150 KW gen set was that the engine casing was cast iron. All the little widgets stayed inside. We had a 30 KW that had two yellow lines painted on it. Wasn't healthy to stand between the yellow lines.
I know about the yellow lines. They had small, portable gas turbine driven emergency 250 gpm fire fighting pumps in the Navy for a while. The instructors warned us never to stand in line with the turbine casing when starting or running them. The instructors told us that a sailor had been killed by one of the small turbines when it exploded and sent shrapnel flying everywhere! It even damaged the building. Fortunately for me my ship didn't have any. We used the ones that were powered by a 2 cycle Johnson outboard engine. They were called P250s.The good thing about the D424A, 150 KW gen set was that the engine casing was cast iron. All the little widgets stayed inside.
