Flame retardant platform

[dhock194]

All:

We have recently done some remodeling in one of our campuses, requiring us to build a new 24" high platform. We went through the permitting process, ensuring we were including all codes and inclusions that the city wanted, and built to those specs.

The installed platform surface, as specified in the permit docs (and approved) was a masonite top over soundboard over 1.05 t&g flooring ply -- very dead and solid, recommended by the local college theater director.

The city inspector came in to give us the final sign off, and they commented that the platform surface would need to be covered by a flame retardant surface to meet the fire code.

Any ideas on the type of top surface that might meet this requirement, and/or treatment that can allow the current top to meet this code requirement?

Thanks!

May depend on how the space is classified. Is it a "theatre" or is it an "assembly" occupancy. In a theatrical setting, the hardboard surface is usually painted to look better, seal the fibres and be easier to clean. Various paints are IFR (or can can have additives mixed in) to create a flame resistant surface.

If your inspector is not familiar with theatrical practices, you'll have to ask him/her what will satisfy.
