And the cloud height, H, at 5 m. Representative values of bulk density, ⍴bulk, were taken from an online bulk density chart [11]. 1. Now compare these values of C with the following representative values of minimum explosible concentration (MEC): calcium stearate (30 g/m3), coal dust (80 g/m3), corn flour (60 g/m3), and iron powder (300 g/m3). 8 5 450 38 An Introduction to Dust Explosions not refer to any particular particle size distribution or dust composition (beyond the generic identifiers given).

4 shows an alternative dust removal method, in this case for the collection of samples to determine dust accumulation rates. Second, the practice would raise dust into suspension to the point where it could accumulate on elevated horizontal surfaces [2]. 4 Use of a portable vacuum for dust collection from round ductwork to enable measurement of dust accumulation rates [7]. ) 36 An Introduction to Dust Explosions igniting have been described by the CSB [8]. A particularly insidious hazard is the presence of combustible dust layers in locations (elevated or otherwise) that are not readily visible.

I tell my plant managers to write their name on their business card and then place the card on a surface known to collect dust. It’s time to clean up when they can’t read their name because of layered dust (Anonymous, 2012. Personal communication, with permission). 3 HOUSEKEEPING The removal of dust deposits by good housekeeping practices is a primary line of defense against dust explosions. S. National Fire Protection Association (NFPA) criteria for dust layer thicknesses, Rodgers [5] reports on several possible misinterpretations of such housekeeping requirements—one of which is the notion that only layers thicker than 1/32 in.
