Forget any misting sprays anywere closely associate with electricity, this will create sparks and an explosive reaction, plus the fans should also be explosion proof.
Suggest an alarm monitoring system that isolates all power to plant area, and triggers release of remote power supply. That also starts extract fans [EP ] to clear vapour.As for spraying water on liquid ammonia in a bunded area ,say around vessels etc., you will create a bigger cloud of vapour than you can handle.
Check your local health and safety chemical hazard safety requirements.
Agreed. People seem to think spraying water on liquid ammonia is good because the ammonia is anhydrous and will absorb the water. To some degree this is true however, the water will be warmer than the liquid ammonia laying in the containment area. Once the water hits the ammonia the ammonia will begin to flash off and create a vapor cloud. That's the dangerous part if the liquid has been contained.

You need to reevaluate your goals...
