Fire Protection Needs for Vehicle Bridge?

6/9/2020

Anyone have experience with fire protection for a vehicle bridge?

I must review NFPA 502 but I wanted practical experience, too. The project information I have is minimal at this point, but I looked in NFPA 502 and assume some kind of dry pipe system to supply hydrants and potentially sprinklers on the bridge would be necessary at this point.

Just looking for some guidance based on past experience.

I haven't seen sprinklers before, but that doesn't mean someone hasn't used them. Depending on the location, I have seen standpipes fed from pump houses on either end (GWB) and fire boat connections (Ben Franklin).

Along I-95 and the NJ Turnpike you'll see standpipe connections at over/under passes for the local FD to use when an exit is far away.

There are dry FDC connections at the elevated sections of I-64 adjacent to Busch Stadium in St. Louis.
The attachments had to meet MODOT requirements.

Are both sides of the bridge the same AHJ and water service area? If not you may need to coordinate water and access with both sides.
