Zone 1 {Dust 21 similar} (Gas presence 10 ‐1000 hours/year) Area where an explosive gas mixture is likely to occur under normal operations Zone 2 {Dust 22 similar} (Gas presence < 10 hours/year) Area where an explosive gas mixture is unlikely to occur (or occur only under abnormal conditions)
Dust Control Solutions Comparison Example. To help understand the influence a pointofuse dust control strategy can have on facility''s operational costs, consider a typical grain elevator handling 40,000 bushels per hour of grain, transferring from rail to barges. Figure 1 shows this typical elevator site with a conventional centralized dust control strategy.
