"the right Sprinkler Head for the right job"
in a Hallway of a hotel or apartment building most AHJ's will accept a
residential head---or
you can use a light hazard head.....

Residential Heads----react fast --- high wall wetting---- Prevent Flashover
--- and give opportunity
to Exit..... usually  .05 gpm /sqft

Light Hazard Quick Response   .10 gpm /sqft   a lot more water ....but is
it Superior? ...for Life Safety?

we started off with THIS quote
"light hazard residential exposed “loft” space"
hmmmm  what is that?  a Live Work unit?  a painter? potter with kiln?  or
just a residence?
