l S There is a considerable body of documented evidence indicating that electrostatic discharge can ignite dust clouds under the right conditions; however, the panel found no evidence of ignition due to electrostatic discharge in its investigations of explosions.

First Priority Actions .e Continue research on methods for reducing the dust concentration in legs to a level below the lower explosive limit.* Establish a housekeeping program involving a mechanical dust collection system supplemented by manual or other means.

From page 11... ...
Treat the avoidance of dust explosion hazards as an initial design criteria in the construction of new mills and elevators and the modification of existing structures. Continue research on methods for reducing dust concentrations below the lower explosive limit in enclosures other than legs.
|
From page 12... ...
Investigate the effect of electrostatics and absolute humidity on the explosion hazard, including. an examination of conveyor belt conductivity and the charging of ungrounded 'conductive structures Apply state-of-the-art techniques to reduce the concentration of airborne dust.below the rawer explosive limit where possible in enclosure" other than legs .
