Interoffice Communication To Keith Fogg From Thomas Grumbles oate May 1 , 1930 Subject POLYCHLORINATED BIPHENYLS > Attached is some information on PCB's. As you will see from this material, PCB's are recognized mutagens, considered poten tial carcinogens and also have known acute affects. Although an inhalation hazard can exist with PCB's, the dermal or skin effects are of greater consideration in the situations your electricians are likely to encounter. PCB's can be absorbed through the skin, resulting in sytemic toxicity, as well as cause localized skin effects. For this reason the proper pro tective clothing and work practices are important to prevent skin contact. It is an EPA requirement that all PCB containing equioment be labeled. You should assure yourself that this is the case in the plant. We have labels if you need them. Let me know if you need more information. Thomis G. Grumbles aj o attachments CCR 000002719
