Fuji Forte' Fixer?

I have been given several gallons of Fuji Forte' Fixer with separate bottles of hardener. Does anyone here have experience using this fixer with panchromatic film?

Thanks in advance.

Best,

Still trying to get information on this fixer. It is used in graphic arts but can it be used in BW photography. I have successfully fixed out old B&W photo paper for carbon printing. It was mixed 1+4 H2O as per instructions.
SDS sheet says:
Ammonium Thiosulfate 40-60%
Ammonium Bisulfite. 1 - 5%
Ammonium Acetate. 0.5 - 1.5%
Acetic Acid. 0.5 - 1.5%
Citric Acid. 0.5 - 1.5%

Any feed back would be appreciated.
Finding someone at Fuji to talk to about this is challenging so far.

Thanks
