PH10 is seriously nasty. Would not dive that in anything less than a complete environment suit (as stated already rubber dry syuit and attached KMB 17 - or equivalent).
Would do nothing for the complexion!
And definitely would not look to be using my own kit. If transporting a compressor etc is peanuts, why not invent some reason to get the company to provide a reason to dive - they provide the 'disposable' gear

.
Good luck and let us know how it goes!
