Hazzardous Classification - Grain Milling

[charlie b]

Just looking for opinions here. We are discussing this in our office, but have not yet been called upon to participate in the project.

There is a machine that crushes grain as part of a brewery operation. Would the process generate "dust," which would possibly put us in Class II? Would it instead generate "fibers or flyings," which would possibly put us in Class III?

I suggest reviewing the definition of combustible dust in Section 500.2. The odds are, if the grain is simply crushed, it is not classified at all.
