February 14 through February 18 in the direct area of the debris pile at ground
zero. To protect workers at the work site, EPA takes grab samples of VOCs where
smoke plumes have been sighted. The results are snapshots of the levels at a
moment in time. OSHA's protective standards set a permissible exposure limit
(PEL) averaged over an 8-hour day.
All samples taken from February 14 through February 18 at EPA's Wash Tent
(West & Murray Streets), Austin Tobin Plaza, the South Tower debris pile, and the
North Tower debris pile either showed no detectable levels of VOC's, or the levels
of VOC's did not exceed OSHA standards.
