a visual inspection is the most important part of any PAT test.


'How?'! So you're not familiar with the PAT test and the consequences of failures.

If you need statistics to work out that PAT testing reduces fire risk
you should really see your doctor.


OK. Now tell us how PAT would show up the likelihood of a fire in an
appliance like a fridge.

Do you actually know what PAT involves?


Lol. Go see the doc about your dementia. Seriously.

I am well aware of the PAT test, thank you. So, you'd happly pass
something with flex where the outer sheath is broken, where the cord grip
on the plug is no longer gripping, etc. You check for all these things
before wasting time doing insulation tests, etc. I was doing them with a
Megger long before an intgrated PAT test machine was invented.

There are plenty of people who "PAT Test" who think all you do is to plug
the appliance into the little box, push the button and read if it says
"Pass" or "Fail".

Are you qualified to do PAT? Several on here are. And know what it

No but the chances of both being full of smoke is somewhat less.


Not so sure of that. If the same mistakes are made with both after a

I will reserve judgement on that until we know what was done and what

2017, "Dave Plowman (News)" remarked:
On Newsnight yeaterday, a Grenfell estate resident (but not a resident of
the tower) said that there were unprotected gas pipes running up the
stairwell. This was also mentioned earlier by residents. But not by any
pros I heard interviewed.

Based on other comments, I thought initially they had gone over to
individual heating systems in each flat - hence the need for new gas
pipes. But it seems this is wrong - it had a new communal heating system.

So why the need for new gas pipes to all the flats? Or are they in fact
not gas but water? A layman might well not know the difference.

Sadly, running any new services through a fire protected area might well
compromise that, if badly done.


A picture has re-surfaced, that was posted online right after the fire -
showing a boiler apparently just inside a flat's front door. And loads
of copper *hot water* pipes. Also another picture showing what are
claimed to be cast iron pipes taking gas into individual flats from the
communal areas.

The former was one of the list of possible solutions to delivering
refurbished heating in the original feasibility study, and some sources
suggest the option chosen was a new heat-pump assisted *central* system.
If anyone has access to records of what was actually chosen, it would help.


Each flat had a heat interface unit (HIU) installed, in simple terms
these are heat exchangers; the primary side is connected to the communal
heat source (heat pump and gas fired boilers in this case), the
secondary side is connected to the apartment radiators. There is also
provision for instant hot water which is provided much like it would be
with a combi boiler. Heat meters work out the amount of heat used by
measuring the flow rate and temperature difference between the flow and
return. I am guessing the gas was for cooking.

Wonder what else is in there?

https://www.google.co.uk/search?q=inurl:kctmo.org.uk/files

Grenfell specific :

"the new smoke extract system has been commissioned and is fully
operational"

"Rydon will be fitting vents to the ducts at all the points where the
gas mains run in the building; this
work is compulsory and will take about two hours. They will need access
to your flats"

Not Grenfell specific:

"following fire risk assessments,
the TMO had been working in partnership with the borough
on ensuring that leaseholder doors were compliant following
the programme for replacing tenants’ doors"

"It was queried whether any of the non-compliant fire doors
were in tower blocks, and this was confirmed".

That does not support your view that one single fire should result in a ban.


Pedant.


Having "banned" it, how do you reduce the number of that model which
remain in use?


In social housing, you insist on inspecting the flats, and if an
appliance with the failing model number turns up you remove it.

People won't like it - after all they continue to use those Hotpoint

So you do agree that the core killed the people not the cladding.

The cladding is a quick fix that will keep people happy until it happens

The cladding needs fixing anyway but I wont say why for what should be

up anyway.

Wouldn't it make more sense to inspect the fire escape methods - making
sure firedoors etc are working and clear? And so on? That obviously isn't
done in many cases, presumably due to the lack of will or money to do it.

Any electrical appliance can cause a fire. If the circumstances are right.
If you wish to stop such a fire quickly, sprinklers are the obvious answer.

Why are you trying to put words in my mouth? As I keep on saying, the
emergency exit became unusable far too quickly due to smoke, etc. The
stairwell didn't collapse (or whatever) as it would have if a core issue.
What hopefully an enquiry will find out is just why it no longer worked as
designed.

The cladding is a quick fix that will keep people happy until it happens

Yes, but there are few particular models which have specific reasons for
concern. Look back at the quotes I posted from the Fire Service.

Almost every situation has both primary and secondary safety. You check
that car brakes work, but you also provide seatbelts and airbags for

You really are thick as pig ****, dennis. Here it is in words of less
than one syllable for you, since you seem rather hard of thinking:

1. The core was designed to allow escape from one or two individual
flats if those were on fire. It was not designed for a mass evacuation.

2. The building was originally designed to contain a fire within a flat
for up to 30 minutes or an hour, depending which spec you read.

3. The residents were told to stay put if the fire was not in their
flat. Here's a picture for you, since you appear to have reading
comprehension issues:

https://static.independent.co.uk/s3f...mage/2017/06/1
4/09/stay-put.jpg

4. The cladding, fitted after the building was constructed, started
simultaneous fires in multiple flats, meaning mutiple tenants needed to
escape, which meant the escape stairwell and smoke ventilation system
were not able to cope.

5. Had the cladding been fire-retardant as per the original spec, the
disaster would not have occurred. Why do you think councils and housing
associations all over the country are right this minute ripping off non-
fire-retardant cladding?

It'll stop a fire spreading to more than one flat, at which point the
regular evacuation processes will be sufficient in most cases.

Have you forgotten, so soon, that the LFB is called out to two high-rise
fires per *day*?

Very likely. And the point is why did that smoke get into the fire escape
route so quickly? It had no windows to fail and let it in.

The refurbishment claimed to have a smoke extraction system.

Don't be silly. The number of road accidents due to brake failure is tiny.

Funny you should say that - the residents in Camden were up in arms that
every flat hadn't been visited by a council worker in a period of half
an hour when the decision to evacuate was made.

In other news, the Grenfell fridge/freezer was made between 2006 and
2009, so timescales for this kind of thing can be measured in years.

Rented buildings require gas safety inspections annually, already. This
could be tacked onto that.

While the cladding is obviously an issue, it wouldn't have been so
much if people had been able to escape.

So you do agree that the core killed the people not the cladding.

It's the *combination* which was fatal.


Do stop trying to hide the real issue.


They died because they couldn't get out end of story.


The cladding didn't stop them getting out.


no, the fumes and heat from the burning cladding did , though.


Very likely. And the point is why did that smoke get into the fire escape
route so quickly? It had no windows to fail and let it in.


"Inadequate" fire doors probably. There are strong hints that the flat
with the original fire had a front door which was sufficiently open,
suffieicently long, for neighbours to be able to see inside. Perhaps
they could be equipped with explosive bolts to ensure that once a fire
has started they could never be opened?

The refurbishment claimed to have a smoke extraction system.


To cope with the smoke from one burning flat, not a hundred.

The one thing you can be sure of is nothing that Curries does is just for
the benefit of their customers.

If all the flats were on fire, no need for an escape route. Everyone would
be dead.

But the smoke from each flat has to get past the front door and the
firedoors protecting the staircase.

How? An inspection of the cables and plugs might but a PAT test?

a visual inspection is the most important part of any PAT test.

'How?'! So you're not familiar with the PAT test and the consequences
of failures.


I am well aware of the PAT test, thank you. So, you'd happly pass
something with flex where the outer sheath is broken, where the cord
grip on the plug is no longer gripping, etc.


Is there something in the water round here today? I don't remember you
playing the loon before.


What's wrong with what I wrote?


seriously?

Really? Got some statistics to back that up?

If you need statistics to work out that PAT testing reduces fire risk
you should really see your doctor.

OK. Now tell us how PAT would show up the likelihood of a fire in an
appliance like a fridge.

Do you actually know what PAT involves?


Lol. Go see the doc about your dementia. Seriously.


Are you qualified to do PAT?


yes

Several on here are. And know what it
involves. And it doesn't involve taking a fridge apart checking for
possible future faults.


I can really only conclude that there is something in the water.

Don't be silly. The number of road accidents due to brake failure is

anyway.


The latter is a way to increase the primary safety, and annual MOT
tests rub that home. The lack of brake failures is a success, not a

What Dave is overlooking is that brake "failure" is not just a
mechanical issue. Failing to notice that the klod in front has come to
rest due to a queue of traffic on the motorway, and biffing into him, is
also a brake "failure". Which is when the secondary safety kicks in.


Now I understand where you're coming from. Failing to operate the brakes
is brake failure. No wonder you were so easily taken in by Brexit.

Having jointed steering columns is another example, resisted by Detroit
IIRC even though there were plenty of road accidents in the US where
the driver was speared by the steering column.


Detroit stuck with steering boxes when the norm elsewhere became steering
racks. And they are situated differently.

I'm prepared to ring-fence the debate to failure of the brakes to work
at all. That more than adequately makes the point I was advancing.

Wrong kind of smoke. The problem smoke is that getting into the
not-on-fire core from flats which are ablaze. Those are the flats where
the cunning evacuation plan only has one per tower block alight at any
one time.

Would a huge fan at the entrance help to some extent? During the moments when the front door wasn't open it would blow outdoor air in to clear the stairwell of smoke and to some variable degree reduce smoke in the passages to the stairs. By the time the stairs are clogged with people & the front door open all the time it would stop being effective, but it could be of use before that point. And it would be very cheap.
