No but there is a safety issue. If the agent is non-toxic, such as FM200, it is only non-toxic at the designed concentration, exceed that and it could become lethal.
Engine rooms are considered normally unoccupied spaces, so there is no mandate in the US for non-toxic agents, however, toxic agents cannot be used on CE compliant vessels.
I spec non-toxic clean agents for engine rooms, even if not mandated. I spend a lot of time in engine rooms, as do many of my clients, I want that protection in that space.
