Included are tenta tive specifications for the crude, Aroclor 1129. These specifications on the crude should be met if the refining system is to produce satis factory MCS 1043. Analytical procedures are given in Appendix B. Also, method numbers for standard methods are given in the specifications in Appendix a . CONTROL ANALYSES Control analyses are required in both process steps, chlorination and fractionation. In chlorination, specific gravities must be run on effluent from each chlorination stage and especially from the last stage. The sampling procedures and frequency used now for making Aroclor 1142 should be adequate for this process. Samples of Aroclor 1129 should be analyzed by GLC to ensure that the material meets the tentative specifications. A 16 oz. sample taken once a day should be sufficient for this purpose. In fractionation, control samples will be needed to determine the end of the biphenyl forecut and to determine the end of the fraction ation. As the end of the forecut nears, samples of the instantaneous distillate should be taken for every 1 or 2% of the charge distilled (approximately 200 to 400 gallon increments). A 16 oz. sample would be sufficient. A GLC analysis to determine biphenyl content will be required. In determining end of the fractionation, it will be necessary to ana lyze both the material accumulated in the distllate receiver and the material accumulated in the product storage tank. GLC analysis will be required, and a 16 oz. sample should be sufficient. As the end of the fractionation nears, it is recommended that samples be taken for every 1 or 2% of the charge distilled (an increment again of 200 to 400 gallons of distillate). From analysis of these two samples it can be decided whether to take off more distillate or to shut down. TOXICITY AND HAZARDS The following section has been lifted bodily from the report "Sug gested Procedure for MCS 1043" by J. E. Silver (Report No. P-1584).

The samples of Arocl-or taken during the chlorination reaction are I. hot (170C.). Precaution must be taken to avoid skin contact of j samples and inhalation of Hydrogen Chloride, Chlorine and Aroclor vapors. 5, Fires .' Fires may result from the ignition of leaking gas, Xylene, Diphenyl, rags, paper, wood, etc. Automatic fire extinguishers and sprinklers have been installed to combat fires. Explosions Explosions may be caused from accumulated pockets of natural gas or a rapid burning of Diphenyl in a closed container such as a Chlorinator. Chlorinators are equipped with a 3" diameter pressure relief line with a rupture disc made to burst at 47 psi . in case Diphenyl within the Chlorinator ignites. 5. Toxicity Toxicity does not present a serious problem. However, a complete dally chang of clean clothes is supplied to each person and time is allotted at the end of each shift to take a bath. Instructions are also issued.to avoid actual skin contact with Biphenyl and Aroclor as much as possible-and to wash hands and face before eating. 6, Miscellaneous There are many accidents that can occur that may be classified as health and safety hazards. These accidents may result from such things as broken process lines, acid leaks, steam leaks, etc. The worst inherent hazards are as- follows: * s' 1. Free Chlorine from ruptured line or major leak. .,2*. HC1 Gas from ruptured line or major leak. V Dropping bottoms from stills. 4. Hot Aroclor & Diphenyl.
