Compressed gas suppressants, such as FE-241® and HRC-227ea, will not stall a diesel engine.
If fire breaks out aboard a diesel-powered vessel, the engine must be shut down immediately.
A running diesel will continue to pump fuel into the engine compartment.
A running diesel also consumes large quantities of air, and can actually suck the extinguishing agent right out of the engine compartment — allowing for possible re-ignition.
Any running engine compartment blowers exacerbate the problem.
