Just wondering what your dept. does to protect exposers. Just SFD not a common cockloft or connected, just a basic wood frame, with another house close. I've always read and heard to switch from the fire to the exposure with a 2.5", and that water curtains were inaffective, because the radiant heat will go right through the curtain. Don't know if that is the most effective way, so just trying to get some ideas on what you may do.
