   more info re sprinklers and the possibility of 
floor-to-ceiling walls around a fabmatlab shop area. 

a link re fire sprinkler types: 

   a pdf for sprinklers for the miami airport 
notes a general 130 square foot coverage area 
for each sprinkler and a maximum distance of 
12 feet between sprinkler heads. 
   it also mentions "nfpa". i do not include 
a related link in this email. 

   an nfpa list of standards: 
   you gotta be a registered member to see it; i 
don't want to register with this org at this time. 

   this pdf mentions sprinkler location but 
references nfpa 13 and manufacturers' specs. 

   this pdf tells how great it is to have 
sprinklers and has a few good notes about 
blocking sprinklers (nothing stacked within 18 
inches of the sprinkler heads, don't let the 
painters get paint on the sprinkler heads...): 

   from wikipedia: 
   scroll down to the design section. seems possible 
to extrapolate coverage from 

"design density would be 0.1 US gallons per minute (6.3×10−6 m3/s) per 1
square foot (0.093 m2) or a minimum of 150 US gallons per minute (0.0095
m3/s) applied over the 1,500-square-foot (140 m2) design area." 

   the idea would be: where ever the shop is
ultimately located, assuming floor-to-ceiling 
walls, calculate what the "coverage" would and 
also should be within the enclosed space, 
figuring sprinklers as-is. 

that's it for me for now.
