Additional information. On April 15, 1974, Information and data were pre sented to representatives of 06HA, NI03II and the XPA by the Industrial Bio-Test Laboratories, Northbrook, Hllnole, ctmc*ming results of animal ex posure studies with VC, sponsored by the Manufacturing Chemists Association (MCA). Although only preliminary In nature, these results revealed that 2 out of 200 t"V* exposed to VC concentrations at 50 ppm for 7 hour* a day, five days a week, for approximately 7 months, de veloped angiosarcomas of the fiver. The Industrial Bio-Test Lob data In dicate that exposure to VC at 50 ppm may well constitute a serious health haz ard to employees. Also, the question of a safe level of exposure for humans can not be determined at this time, and may continue as a matter for scientific de liberation for many years. We therefor# conclude that it 1* now necessary to pro pose to change the 50 ppm level estab lished In the ETB to as low a leval as can b* detected using methodologies outlined In this proposal.

However, the FAA believes It is Important to re view all relevant data on safety and cost con<riderations that may be applicable to any propos'd change In the Type A exit passenger seating limitation. To this end, the FAA solicits data, views, and argu ments from OH interested persons on the questions set forth brtow.
