5. In cases where recommended exposure limits are below the detection limit
for the compound in question, the estimated lower limit of detection has
been substituted for those values.
6.
The 2020ppbPRO is not suitable for monitoring these compounds at ACGIH
recommended levels.
7.
A 1000-ppm TWA has been established for those compounds which are
“Simple Asphyxiates” and for which no exposure value exists.
8.
For those compounds, which lack established exposure levels, an arbitrary
value of 200 ppm has been established for the TWA, STEL and PEAK
alarms.
