THE REGULATORY REFORM (FIRE SAFETY) ORDER 2005 => Q & A => Topic started by: Karissa on June 02, 2010, 10:49:27 AM

I would be interested in how you folks read this recommendation :)
From the RRO documentation:
"An emergency escape lighting system should
normally cover the following:
...
• windowless rooms and toilet
accommodation exceeding 8m²;
..."
Is that 8 metres squared (8x8), or 8 square metres (2x4)?
I look forward to your replies ;)
-
I have always read it as the latter - 8 square meteres - i.e. 2m x 4m for exaple.

8sqM is 4M x 2M or 2.83M ish x 2.83M ish.
-
8m2 means 8 square metres
Definitely not 8m x 8m.
-
That's what I always thought ;D
Don't you just love clients and 'open to interpretation' and 'how much can I get away with' ::)
-
8m x 8m = 64 square metres surely?
-
Lets not forget its a guide though- 8 sq m ish.
There may be reasons to include lighting in some smaller ones with additional hazards and some larger ones may be ok without.

Afterburner, it's a mathematical units thing... Look at it this way.... 8m x 8m = (8 x m) x (8 x m) = (8x8=64) (mxm=m2) = 64m2
Just the same way where if we multiply it by a further 2m in another direction it becomes 128m3. (8x8x2) (mxmxm)
So in effect, having the "2" there shows that the multiplication has already taken place, if you can see that.
(FWIW I used to look at it your way, sq.m and m2 were 2 different things)

If we're done with the 8s can we move on to our 9s times tables please?
9 x 1 is 10
9 x 2 is 3 bananas
This is easy.

You assessors are nothing but trouble! Always fudging the prescription with your oohs, aahs and mmms!

If I have two beans, and then I add two more beans, what do I have?

Not goin to answer that because the obvious answer will be wrong and, despite it being very easily done, you will make me look stupid. So I am going to sayyyyyyyyyyyyyyyyy 7.

a = b
a2 = ab
a2 - b2 = ab - b2
Factorising is the bit that's not obvious but trust me, the following is logically correct from the foregoing:
(a+b)(a-b) = b(a-b)
Divide by (a-b):
a+b = b
b+b = b
2b = b
2 = 1

Some beans.

A very compliant, not so jolly green giant?

Never mind how many balls you can place in each hand.If the power failed in the bog and you couldnt find your way out cos its pitch black and you aint got no borrowed light then you probably need emergency lighting. Seriously I carry this forum, what would you do without me?I should get an award.

kurnal got it ;)
How many beans to make a very small casserole?
PS sorry for going off topic :-X

Kurnal, you are a subversive revolutionary. If it says 8 sq metres, surely you know in the brave new world of the fire police, 8.1 sq metres is a hanging offence (unless of course you have crown immunity, but then you comply voluntarily, dont you). Dont tell them your real name Alan, or there will be a knock on your door in the middle of the night and you will be whisked away for reprogamming for suggesting that codes of practice are not rigid rules that do not need to be hugged religiously.
If the fire safety fuehrer reads this, I won't crack and give you Alan K's home address no matter how much you torture me (unless you threaten that Joanna Lumley will never talk to me or you give me a bottle of talisker).

(a+b)(a-b) = b(a-b)
a - b = 0
Divide by (a-b)
Naughty Stu!
I wasted 20 minutes of my day on this. Don't do it again!
