I'm not sure the causes really matter much. As said, both released huge amounts of dioxins, which in one way is what matters most. Yes, firemen and others were exposed for days/weeks afterwards, and one of the questions currently being avoided by the Grenfell authorities is why was nobody's blood tested afterwards? As for what will happen in future - clearly, by the way the government, council and Inquiry is concerned, hopefully nothing. 17 months on from the fire and no questions at all have been answered; nobody brought to task. It hasn't even been determined whether or not the cladding insulation contained flame retardant chemicals - and believe me, there are huge profits to be made or lost according to what the answer is to that particular question.
