I am building out a space that has been vacant for multiple years. The space has a hydraulic elevator that travels 1 floor. There is a sub that is ushering the elevator contractor through the certificate milestone with all the adjacent trades.
He has proposed to change out the Class III-B hydraulic fluid with a Hydro-Safe or equivalent non-combustible fluid in order to work around the NFPA 13 requirement for a pit sprinkler and pit detection to be installed.
My question is, does swapping the petrol-based fluid to a bio-equivalent have any long-term effects on the pump, pistol, seals, gaskets, etc.?
Also, how do I make sure this is the fluid that remains in use for the life of the certificate?
