Subject says it all!
You don't need a rule reference saying they don't prevent spreading. They don't prevent spreading because there is no rule saying they do.Is there a rule reference for that answer?
Is there a rule reference for that answer?
TIA,

Or is it just considered standard application of the spreading fire rules since there is no exception - that we could find, anyway.No...
Right, I see others have stated that...Or is it just considered standard application of the spreading fire rules since there is no exception - that we could find, anyway.
You could say that for about any terrain, so I don't think that your path of reasoning is correct.You don't need a rule reference saying they don't prevent spreading. They don't prevent spreading because there is no rule saying they do.
Then I am probably not being clear enough.You could say that for about any terrain, so I don't think that your path of reasoning is correct.
This leads to the conclusion that fire can spread across a hexside water obstacle and up/down a cliff. I have no problem with any of these. It would probably be a fairly rare hexside black bar wall that was truly fireproof. Most would have spaces between floors and/or through vents and/or across the attic and/or would be subject to breaching by falling, possibly flaming debris.The "base" spreading rule is pretty much that no terrain prevents spreading. I.e., for an Interior Wall to NOT prevent spreading there does not need to be any rule saying that - it is alreadt in the "base rule.
What brought up the question was a factory wall in RB. But since the black bar rules refer to rowhouses, and having lived in one of those in N. America, they are fairly fireproof being made of concrete, but a fire *could* still spread via the roofs of a rowhouse or even by conduction through the concrete wall if it gets hot enough. You can choose a realism argument to suit your preferences. But I prefer to play by the rules as written!This leads to the conclusion that fire can spread across a hexside water obstacle and up/down a cliff. I have no problem with any of these.

I think that is what B25.6 says (barring any exceptions [I'll admit have not searched for any]):This leads to the conclusion that fire can spread across a hexside water obstacle and up/down a cliff.

As I said, if they are made to (current, up-to-date) code they are fairly (but not entirely) fireproof. Codes were probably not as stringent at the time, and there are probably no fire codes of that kind in a factory. Also as wikipedia has it, "A firewall is a fire-resistant barrier used to prevent the spread of fire for a prescribed period of time." Note the caveat. A firewall will typically slow the spread of fire. Only very exceptional walls will stop it. So perhaps some black bars might be DRMs to spreading DRs, but typically they would not prevent spread entirely.What brought up the question was a factory wall in RB.

Maybe codeine?What stuff is code made of?
The rowhouse rules don't mention anything about the construction of the black bar. The black bar simply indicates that there is no direct entry from one rowhouse to the other. Anything else is an assumption. Since there is no specific exception(s) noted for the black bar vs blaze spread, there isn't any.As I said, if they are made to (current, up-to-date) code they are fairly (but not entirely) fireproof.

I believe that the "directly attached" Spread DRM makes the difference when a non burnable terrain hexside separates the blase from an adjacent, burnable terrain.This leads to the conclusion that fire can spread across a hexside water obstacle and up/down a cliff.
