To lighten the mood as we go into Memorial Day weekend.... Sometime around 2007, there was a rather large discussion on the size of a piece of combustible dust. The standards are not aligned (see 'combustible dust' in the Glossary of Terms). The argument, I mean debate, of the floor of the worldwide NFPA Technical Meeting was intense. People got very emotional about how many microns it takes to be an official dust particulate. From all sides of the room came shouts of "360 microns", "400 microns", "500 microns", and what seemed HUGE: "600 microns"..... for the record a micron is about the thickness of a sheet of paper.
The debate went for what seemed like hours! (it was about 60 minutes) And the vote failed to change anything........ I could listen to hours and hours of fire sprinkler debate, but I was dyin' that day!! It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.
