The requirements for handling and disposing of transformer minerals oils containing more than 50 ppM PCB are, by federal regulation, different from those for oils containing lower concentrations. A rapid and simple test to distinguish between samples containing more than or less than this concentration would simplify proper control of transformer oils. This report describes the development of a small disposable test kit that can be used on-site to screen the chlorine content of transformer oils. The kit consists of two soft plastic tubes in which thin walled glass ampules containing premeasured amounts of reagents are broken. The reaction sequence in the kits converts the chlorine in PCB to chloride ion. The color of the liquid in the kit after the last step is blue to purple if the chloride content due to the initial chlorine concentration of the oil is less than 20 ppM. If the chlorine content of the oil is below 20 ppM, the PCB content must be below 50 ppM. The liquid is colorless if the chlorine content is greater than 20 ppM. In this latter case, it is necessary to determine by gas chromatography whether the PCB content is actually greater than 50 ppM or if there is some other source of chlorine in the oil.
