Essay

Consider the following observed concentrations of air contaminants:
$\begin{array}{lcc}&\text { TWA } &\text { PEL } \\\text { Isopropyl ether } & 200 \mathrm{ppm} & 500 \mathrm{ppm} \\\text { Ethyl benzene } & 40 \mathrm{ppm} & 100 \mathrm{ppm} \\\text { Chlorobenzene } & 25 \mathrm{ppm} & 75 \mathrm{ppm} \\\text { Chlorobromomethane } & 50 \mathrm{ppm} & 200 \mathrm{ppm}\end{array}$
Perform calculations to determine whether this atmosphere exceeds the PEL, the AL, or both.
