What were to happen if deicing fluid went in to the jet-engine?
Deicing fluid is inhaled by jet engines nearly every time the truck is called out. The question is how much deice can the engines tolerate? 

Turbine engines can accept a rather staggering amount of water, to the point that testing them becomes an exercise in water handling instead of engine handling. The fire department can empty their trucks into an idling engine and not affect it.

Deice does contain various flammable liquids, but the overall mixture is not flammable - rather dangerous although fire would be a quick way to clear the ice.

So, unless you find a way to empty the truck into the engine in less than a few seconds it's simply not an issue.
