Dont do the water spray thing.. it might stop him snapping, its not going to make him stop FEELING like he wants to snap!
We shouldnt anthropomorphise.... but.
Put yourself in his shoes. You are deaf, you are small, and you live with a big group of.. err.. elephants. You dont know the rules, you cant communicate and they push you around and pick you up and plonk you in different places youve never been before.
You get hurt one day, someone grabs your shirt collar and tweeks your hair hard at the same time, by accident, but you react by turning round and yelling loudly and trying to thump the elephant. The elephant backs off.
You use this method because finally, they at least understand when you dont want to be pushed about. Its the ONLY message you can convey.
And then they start spraying you with water whenever you try to communicate.
I realise, we are humans not elephants, he is a dog not a person... but in the above situation, you wouldnt be feeling particularly happy or confident all the time would you, and certainly not relaxed.
You need a method to remove him from a situation wtihout getting snapped at, so put a trailing lead on his collar, one without a loop at the end so it cant get caught on anything, and use that to keep outo f the way of snapping, so you dont back down, to remove him from where ever without being confrontational.
It wouldnt do any harm to read up on clicker training (i realise you cant use a clicker), get to understand the basics of positive reward based training and think how you can apply it to the dog.
I would start off with rewarding him for looking at you, perhaps you could use something with a light on it that you can light up (kids torch?) instead of the click. Then put that on a cue.
It IS very possible to train deaf dogs and train them well! You just need to think your way round it. Once a dog learns that making eye contact with you is rewarding, he will be able to learn lots of other things, using hand signals rather than voice commands, and he will start to look to you for instruction!
