1 NIOSH 1990a.

2 From facility (downwind); exceedance begins at facility, 0 meters, unless indicated otherwise.

3 Offsite individual exposed to concentration exceeding the limit. TLV - threshold limit value; TWA - time weighted average; TATB - triaminotrinitrobenzene; TNT - trinitrotoluene. Results derived from accident analysis (see appendix F).
