Insulating rim joist with XPS but heat protection needed


I'm planning on using Extruded polystyrene on the furnace room of my basement, see pic below. As you can see they have used fiberglass and and is just stuffed every which way around the pipes and things.

However I'm now reading that I need to protect the insulation from potential fires. I don't plan to use drywall since its a unfinished part of the basement and I don't plan on finishing it. Also from the pic above you can see a plastic barrier. Its only stapled and says its something about flame resistance, see below pic.

Also I'm reading that vapor barrier in the basement is a no-no? Just want to confirm this.
I'm located in Quebec Canada in case that changes any of the regulations.

Your code requires it on the wood rim area as per new Govt. guide of this year; http://www.nrcan.gc.ca/energy/effici...ion/15639#a6-2

Read 6.2.6 and note the "protective" covering on the foamboard... ask local AHJ if foil-faced foamboard will meet the fire rating as this shows it does; http://building.dow.com/en-us/produc...1-b48282f3c7b7

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?
