Definitely not OH of any kind, I'm not even sure I'd go with EH1 owing to the potential depth of piles and chance for deep seated fires in Group A plastics and rubber. Essentially you have a high piled storage situation with uncartoned, unstable piles.
These types of facilities if using front-end loaders can pile materials 15-20 ft high. You should be looking towards CMSA Or ESFR's very carefully. This is definitely not a pick-a-density from the chart type of project. Craig P -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of å... ....

If there is more than an 1/8 inch of dust, no need to go out and measure that 1/8th, just providing a rough picture for coverage over areas exceeding the design area...then yes the fire hazard warrants upping the design area. However, the warrant is issued by FM. 2010 NFPA 13 Section 5.4.1 says good to go with EH-1. -- Scot Deal Excelsior Fire On Wed, Aug 24, 2011 at 6:36 PM, Art Tiroly <[email protected]> wrote: > > I am working on a proposed trash recycling plant.
