Yes, it has been a week. When the fire was first reported I steered clear. It was a fire. What was weird was the ferociousness of the fire, I had questions from the moment I saw the fire, but I waited. I had no Intel, I had no facts and it was a fire after all. Fires happen. Yet, those who saw the limelight seeking photos from the Telegraph might have noticed a thing or two. You see, the fire was like a fire that Hollywood could not do. The Towering inferno was not that intense. The fact that the fire had a casualty list that is massive is also an odd part in all this. So I decided to wait, I would not be the one shouting arson on something that was not that. The consequence is a little too unsettling. Yet now, a week later I found myself collecting what I could. It started with the noise on cladding.
The first thing I found was a similar issue in Victoria, Australia. On April 30th 2015 we see: “Testing conducted by the CSIRO in mid-April on behalf of MFB found that the Alucobest cladding material installed by building company failed to comply with high-rise combustibility requirements“, in addition there is “The external cladding material on this building did not prevent the spread of the fire as required by the Building Code of Australia,” said MFB chief officer Peter Rau“. It was a fire that happened in 2014. So these events had been happening for years. This now gets us to Rydon Ltd in East Sussex. They got the job, because they were £2.5 million cheaper. Like in the Towering Inferno, that place went down in the story because of cutting corners. So my initial thought was that this might be the case here too. The question is ‘Was that the case?‘ You see, it is all good and fine in books, but the reality is how were the materials tested, how did the makers of the original cladding present their materials? One of the parts is ‘Celotex RS5000 PIR thermal insulation‘, when we look at those specification we see: “Fire propagation ‘BS 476: Part 6′, Pass” and “Surface spread of flame ‘BS 476: Part 7′, Class 1“. It comes with the footnote “The fire performance and classification report issued only relates to the components detailed above. Any changes to the components listed will need to be considered by the building designer”
The entire issue becomes more of a mess when we consider that ITV business editor Joel Hills stated that he had been told that the installation of sprinklers had not even been discussed (at http://www.itv.com/news/2017-06-15/grenfell-tower-original-proposed-contractor-was-dropped-to-reduce-cost-of-refurbishment-project/), the ITV article focusses on the ‘cost saving‘ which is correct, yet the one part they do not raise is whether the materials were up to scrap. In addition they do mention two parts that are essential. One is “In 2013 the government wrote to every local authority to encourage them to retrofit sprinkler systems in older tower blocks. It did so at the request of a coroner who leads an inquest into a fire in Camberwell in which six people died“, the second one was “Before passing judgement on whether the Kensington and Chelsea Tenant Management therefore acted irresponsibly, bear in mind that, according to the British Automatic Fire Sprinkler Association, only 100 older tower blocks in Britain have been retrofitted with sprinklers since 2013. Around 4,000 have not“, the councils were apparently put off by the costs, which in this was about £1150 per apartment. We read more about these tests as presented by Celotax (at http://www.ecosafene.com/EN/firetesting/building/228.html), so we get some clarity here. Yet the surface flame test (BS 476-7, linked in the referred page), gives us “Extinguish the pilot flame 1 min after the start of the test“, yet these numbers will not add up, because there were no sprinklers, no dousing the flame, so the entire operation will be working on different elements. This does not invalidate the test, yet if I look at the Ecosafene site I am now looking at ‘BS 476-15：Fire Tests on Building Materials for Measuring the Rate of Heat Release‘ as well as ‘BS 476-5 Fire Test to Building Material for Ignitablity‘, you see, this caught fire somehow, after that Bob is your crispy dead uncle (in this case). Yet in all this, we did not mention Celotex. Their site gives us “As with the rest of the nation our thoughts continue to be with those affected by the terrible fire at Grenfell Tower in London. On Wednesday, as soon as we were able to, we confirmed that our records showed a Celotex product (RS5000) was purchased for use in refurbishing the building. We wanted to provide an update to that statement and provide further information as we are able to. It is important to state that Celotex manufacture rigid board insulation only. We do not manufacture, supply or install cladding. Insulation is one component in a rain screen system, and is positioned in that system behind the cladding material“, It is what we now see in the Metro that kinda takes the biscuit. “Controversial cladding was added to Grenfell Tower in part to improve the view for nearby luxury flats“, which must have been a nice clambake to watch I reckon. It is the term ‘Controversial cladding‘ that now becomes the focus. You see, the Birmingham Mail and others are all about: “Grenfell Tower £8 million refurbishment ‘met all required standards’“, yet the fire does seem to tell a different story. The Guardian has another article linked to all this. The article ‘Complex chain of companies that worked on Grenfell Tower raises oversight concerns‘ (at https://www.theguardian.com/uk-news/2017/jun/15/long-builder-chain-for-grenfell-a-safety-and-accountability-issue) gives a few items a few answers and more questions. In opposition I need to give the quote “Ben Bradford, a fire safety expert who is managing director of the risk consultancy BB7, said the multiple links in the chain of contractors could cause safety problems. “There are probably multiple failings that have occurred in this particular case,” he said. “The work, in terms of fire stopping, often falls to a sub-contractor. They don’t always realise the critical nature of the components they’re installing in the overall system“, I have an issue here. It is not untrue what he is stating, yet the elements on the page give us a little clarity. You see Rydon used Harley Curtain. This setup is not unique. Rydon cannot afford the amount of people needed, hence a subcontractor is used. They would work according to the requirements of Rydon. That link is seen with the subsequent links to Celotex and Arconic. So Celotex is the insulator and we saw all those links, yet now the actual cladding remains. ‘Reynobond PE‘, in the end Rydon had to sign off on that, in clarity, at present Rydon is the responsible part (until valid defence is given). You see, when we go to Arconic, we see “Reynobond PE features a polyethylene core that adds strength and rigidity to the coil-coated aluminium panels. This maximizes its flexibility and formability, while maintaining a light weight for easy installation“, you see, when I went to High School (early 70’s) I was told that polyethylene was combustible, it is a common trait in the polymer group as they are all inflammable family members. You see, perhaps it is just me, but the brochure states: ‘building code recognition‘, is that the same as passing a test? The tests Canadian fire tests CAN S101, CAN S102 and CAN S134 are a nice mention, yet the idea that an AMERICAN company is relying on Canadian fire tests got me thinking. I have not found the answer; I am merely puzzled by it. The question is what did Rydon know on that part? They are supposed to be the expected experts, I am not!
The question still gives us a concern, you see the fact that the outside got to play the part of Roman candle is one side, at that point the sprinklers inside the building would have been pretty useless at that point. What is interesting is the mention on page 5 of the brochure: “It’s perfect for new and retrofit projects less than 40 feet (three stories) high” This is an interesting part because the ‘why‘ comes into play, why only 3 stories? That part becomes a point of discussion, as page three shows a 7 story high building in the images. On page 6 we see the safety rating form flames and smoke as a pass with Class A as per ASTM E84. That part revealed two elements. One is the mention ‘This test method measures flame growth on the underside of a horizontal test specimen, using the Steiner tunnel test‘, the operative word is ‘horizontal‘, the next one is shown (at https://www.astm.org/Standards/E84.htm), here we see “This test method exposes a nominal 24-ft (7.32-m) long by 20-in. (508-mm) wide specimen to a controlled air flow and flaming fire exposure adjusted to spread the flame along the entire length of the select grade red oak specimen in 51/2 min“, in addition they do not give ‘measurement of heat transmission‘, which seems a pretty important element in VERTICAL applied cladding, as flames tend to ignore gravity and move upwards adding to the temperature, for those extra crispy roasted victims. More important the ‘effect of aggravated flame spread behaviour of an assembly resulting from the proximity of combustible walls and ceilings‘ and as polyethylene is combustible, we now have an issue. From my point of view, if Rydon signed off on this there is an issue. Yet more important, the fact that there is documentation that goes back to 2014 in Australia and there are a number of buildings in London that have this issue, London Town there is a much larger issue in play. Now, we see that everyone is bashing Theresa May, and as she made me no Bundt cake I am fine with that. Yet this is a long term failure. It has an impact on several administrations on both sides of the political aisle. There is a clear call, one made by MP David Lammy in the Independent (at http://www.independent.co.uk/news/uk/politics/grenfell-tower-fire-corporate-manslaughter-arrests-david-lammy-mp-labour-london-kensington-a7790911.html). I agree that ‘corporate manslaughter‘ is more than a fair call. As the Tottenham Labour MP states this, there is a call for the executives of Rydon to explain and show their elements in all this. They should be in defence mode and it could result in their arrest if clear evidence of negligence is found. The elements I found clearly support that and that is merely the 45 minutes getting through some of the brochures and going through the fire tests. You see, the earlier quote from the Birmingham Mail with ‘met all required standards’ does not hack it in my view. I found three issues in mere minutes, so we either have a systematic failure of government allowing this to continue (even more damning in light of the concerns from the occupants that had been going on for some time), the other side is that underlying communications might or might not exist. There is no way to tell until this is brought into the open. David Lammy might not ‘name’ anyone, but I did, and they should be named. Yet that also means that they can and should defend themselves as they might not be the guilty party, but no matter what, they are to a larger extent, the accountable party until properly investigated. And this is not because I am trying to have a go at Rydon, I want this to come out into the open. The failure that we saw burn is just one of several buildings where cladding has been applied to, and as the train wreck is pushed into the limelight carriage after carriage, only then will we see the complete extent of the failure and there is no ‘walk softly’ that option has been taken away by the dozens of fatalities. A little limelight is the least of the problems these people need to face.
Even as we saw the ‘cost saving‘ there is still going to be a backlash to KCTMO, you see, they made a call on the cheaper option, which might be fair, but why was the ‘other‘ solution cheaper? When those elements are brought to the surface there will be questions as they tend to come, fair or not. This all gets to get political soon thereafter as we saw the ‘reasoning’ of ‘improve the view for nearby luxury flats‘, you see, I am not buying a Versace suit so that I look more appealing to my neighbour. She (and he) can bloody well move to Knightsbridge and get a more expensive view there. Yet, that is just me.
