Notice to Users using HF:
We are seeing an increased usage of 48% HF being used. All 48% HF must be processed in Teflon containers not poly Styrofoam and in addition these containers must be in a secondary container so as to keep the entire system and process in double containment.
The INRF does not provide Teflon containers so users must provide their own.
