Metrology process waste assessment: Fluorinert bath temperature calibration Z951-421-1
Fluorinert, FC-40 and FC-72, was chosen for this pilot Process Waste Assessment (PWA) because it is the most frequently used chemical in Metrology. Fluorinert has been used since 1986 as a substitute for trichloroethylene. Although it is much safer than trichloroethylene, it still has disadvantages. If Fluorinert is taken above its boiling point it will produce toxic chemicals, creating a health hazard rating of 4. To prevent this occurrence, over-temperature controls are installed on the bath and a fume hood is provided for the vapors. Fluorinert is used in a Rosemount Temperature Bath, CE 64138, as a stirred temperature medium which provides a stable temperature environment to compare readings of a Standard Platinum Resistance Thermometer to readings obtained from thermocouples, thermistors, and other types of thermometers. Fluorinert is used primarily to provide a safe liquid medium that can be varied from {minus}120 to 200{degrees}F. When temperature devices are removed from the bath, the excess Fluorinert is removed by wiping with a KayDry. Contaminated KayDrys are disposed of as step can waste.
