AROCLOR APPENDIX J SAFETY & TOXICITY DATA (Cont'd.) 2. Sampling of Crude Aroclor The samples of Aroclor taken during the chlorination reaction ' are hot (170C). Precaution must be taken to avoid Bkin contact of samples and inhalation of hydrogen chloride, chlorine and aroclor vapors. 3. 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, 4. 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 10" diameter pressure relief line with a rupture disc madeto burst at 22 psi in case diphenyl within the chlorinator ignites. 5. Toxicity Toxicity does not present a serious problem. However, a com plete daily change of clean clothes is supplied to each person and time is allotted at the end of each Bhift 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 faoe 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 s u c h things a s broken process lines, acid leaks, steam leaks, etc. The worst inherent hazards are as follows: 1. Free chlorine from ruptured line or major leak. 2. HCl gas from ruptured line or major leak. 3. Dropping bottoms from stills. 4. Hot aroclor and diphenyl. S a fe ty Recorfl 738226 The last lost-time injury in Department 246 was January 28, 1948. The frequency of minor injuries is low, around one per month.
