MrVilla,
The risk of fire/damage to a firehouse/architect post rises slowly, and is typically eliminated whenever the building sends out a fireman/architect. Another burning building can ignite a firehouse next door, but other than that I wouldn't expect to see many firehouses/architect posts burn/collapse. An unstaffed firehouse/architect post (without other protection) will burn/collapse eventually, but I'd expect to see something else (that the firehouse/architect post is supposed to protect) burn/collapse first, which (hopefully) would bring the problem to the player's attention.
C Franziskus,
A couple of times, when needing more jugglers, I've said "these miners could use a little entertainment" and dropped in a booth without thinking. Fortunately, I typically check the Risks overlays often enough to discover the mistake before a fire breaks out.
You might consider me fanatic about not wasting workers--I'd much rather waste money. If I remember correctly, both my On and my Baki have 1 firehouse without damage protection, and my Baki has 2 architect posts without fire protection.
