Lakeland inquest fraught with controversy

"Near the end of the day shift on Jan. 19, 2012, a saw on the large headrig Roche operated "deviated" throwing up sparks and lighting the nearby sawdust.

NFPA Prepares to Issue NFPA 652 Fundamentals of Combustible Dust

From NFPA Journal and - Credible Risk, March April 2015

PREPARING A NEW NFPA STANDARD requires a mixture of ingredients, some provided by the public and the technical committee, others provided by NFPA staff. The aim is that, in the end, we have developed a meaningful document that benefits the targeted occupancy or addresses a particular hazard. The path to completion can sometimes be unusual, as was the case with the new NFPA 652, Fundamentals of Combustible Dust, which is due to be issued this summer.

To ensure that certain deadlines were met, NFPA’s editorial team resorted to humor to catch my attention. I love soccer, and was fortunate to spend time in Brazil last summer at the FIFA World Cup, where I followed the progress of the U.S. side through the so-called “group of death.” When I returned to work, one of the tasks at the top of my list was to review the edits to the Second Revisions for NFPA 652 prior to balloting the committee.

Combustible dust continues to make headlines. One of the top health and safety issues in the woodworking industry, it impacts companies of
all sizes.

OSHA defines combustible dust as “fine particles that present an explosion hazard when suspended in the air, in certain conditions.” For a combustible dust explosion to occur, five factors must be present: fuel (combustible dust), ignition (heat or spark), oxygen
(air), dispersion (dust suspension) and confinement. 

Removal of any one element will eliminate the possibility of occurrence. But far too often, this …
