The pack had been opened and valved off prior to this time. The employee opened the pack, drained water from it and in stalled the new filters, noting a scent of VCM. Employee acting as firewatch for demolition work in old unit when a valve was erroneously removed from a knockout tank recircula tion line (same incident as Vinyl Shift Supervisor overexposure of 1-4 ppm mentioned above). Employee overexposed while sampling 741 and 743 reactors. Employee worked near the new unit knockout tanks preparing for in sulation work. He recalls smelling VCM at one point. v Employee helped correct problem, following filter pack gasket blowout of 10/4/82 mentioned above. Employee blanked out 9Q1 vacuum pump.

Employee worked in old unit entire shift. No cause has been found for the overexposure. The employee and his fellow workers and supervisor have no recollection of anything that may have produced the over exposure.
