Following up on Fire Marshals and flame retardant fabric in Sunday School classrooms...
Two experiences that suggest the Fire Marshall is our friend...
(1) Several years ago, my church's Bldg Committee asked me to spray a cardboard display in a hallway with flame retardant ($10 online).
A few months later, the Fire Marshall was inspecting the building and remarked how nice the display looked.
When the Marshal left, he gave the Bldg Committee a list of all the things THEY were in violation of, or needed to be cautious about, including coffee pots left plugged-in in the adult classrooms. Not a single thing in our kids' classrooms was listed.
(2) In another church, we tacked paper to the walls of a small classroom for a drama. The ceiling had sprinklers, but a trustee complained. When the trustees came to inspect the classroom, they were distracted by the fact that the emergency exit door near the classroom had rusted shut. Embarrassed by their lack of oversight, they didn't bother us about the paper anymore.
