I can agree with this one - to an extent...
... if the smoke alarm goes off in most people’s home in the morning with a smell of burning toast, they see it as a nuisance. Not the detection of an incipient fire. Because they don’t think a toaster or a grill pan can catch fire, because they have no experience of it. Most Firefighters on the other hand do.
Once, when cooking bacon in my brother's house, the smoke alarm at the top of the stairs went off (surprise surprise) so I went to waft it (as you do). When I came back to the cooker the grill was on fire. I have always attributed the cause of the fire to the presence of the smoke alarm. And, sadly, I was a firefighter at the time. I still ate some of the bacon.
I don't know if I can come up with five concerns but here's a couple.
1. Deregulation of fire safety in respect of night clubs. Fire safety in such premises is of paramount importance yet some fire risk assessors do not seem to be able to adequately assess safe capacities.
2. The bungled together nature of BS9999.
3. The fact that under 9999 a club with two 800mm exits will safely accommodate 195 people yet under ADB it will only accommodate 100. (It's the 195 I'm worried about, not the 100.)
4. The large number of errors found in BS7974 and all its PDs.
5. The disgraceful arrogance of many fire engineers which is compounded by their incompetence. The two characteristics seem to be positively correlated.
6. The inadequacy and outdatedness (have I just made up a new word?) of ADB.
Oh, that's six, and I was just getting going. I'll leave it there. 1 and 3 are pretty much the same anyway.
