Final agreement has been reached on a number of improvements in fire safety requirements in the US NFPA 130 Standard for Fixed Guideway Transit and Passenger Rail Systems, mainly resulting from public comment proposals. Improvements include: the requirement that insulation materials in stations must be located behind thermal barriers, gypsum or concrete and must meet building code requirements; new fire safety requirements for rail ties, interior finishes and protective cover boards; testing of adhesives and sealants in rail vehicles for smoke, flame-spread, dripping.
Also, after discussion, the current requirement that wires, cables and other materials be halogen-free was maintained.
