Hi, I'm from Panama. Here in Panama, the NFPA standards are used. and for the construction of a two-story building with metal structure WF view. Firefighters are demanding some 2 hour fire retardant system for columns, beams and slab. In short, they require a system that maintains the metal structure and without failures up to two hours of fire. I need to know where this is mentioned in the NFPA because it is not mentioned in 101. Thank you very much for your help and I hope someone can answer me.
