In regard to pre-judging the outcome of the second stage of the Grenfell Tower inquiry, then it has already been confirmed by that body that it was the cladding on the outside of the tower that became the prime cause of the loss of life in the tragedy due to its combustibility.
However, what that inquiry has now adjudicate on is I feel:-
Did the specification certification for the materials used in the refurbishment accurately evaluate the combustibility of the products.
Did those engaged in the specification and installation of the products used in the refurbishment consider the effects of combining several products on installation would have on the overall combustibility of the fixtures on the tower?
Were adequate and sufficient risk assessments carried out on the above, and if so were the persons who carried out those assessments properly qualified to engage in such work.
Along with many other factors, In the above, there are any number of scenarios that will eventually lead the inquiry, hopefully" to the main root cause of the tragedy and ultimately those responsible.
In my experience inquiries such as Grenfell always turn up the unexpected from the initial thinking on causes immediately following any incident. Many forum members may well remember a Roller Coaster accident in the North Midlands several years ago and in which our company were involved in the investigation.
Several young persons incurred life-changing injuries in the accident and it was widely reported in the media in the immediate aftermath of the incident that the mainly young persons engaged to operate the ride were guilty of gross negligence.
However, through the investigation, it emerged that the safe operating procedures for the ride prescribed in the risk assessments could not be carried out due to the numbers of people the staff were expected to put through the ride by the owners of the Theme Park in peak periods.
Therefore, it emerged by way of the investigation that the root cause of the accident was the working pressure placed on the staff by management and in no way was any negligence of the staff judged as being responsible.
The company responsible were fined a record amount by courts and the most senior executive officer in the company made a public apology prior to then resigning.
That is why I feel that no one at this point in the Grenfell Tower investigation should in any way attempt to prejudge what will be its outcome and final conclusions.
