Using the International Building Code from Table 9.11 (maximum floor area allowances per occupant) for industrial areas, 100 \mathrm{ft}^{2} per occupant is the recommended area:
\begin{aligned}\text { Maximum population } &=\frac{120 \mathrm{ft} \times 200 \mathrm{ft}}{100 \mathrm{ft}^{2} / \text { person }} \\&=240 \text { people }\end{aligned}From Table 9.12 (minimum number of exits for occupant load), given the population, the minimum number of exits required is two.
From Table 9.13, the remoteness requirements can be addressed. That is, how far apart should these doors be to safely move occupants out of the facility?
