I've been obsessed with the US Chemical Safety Board videos on YouTube that describe in great detail the events that lead up to industrial accidents. One of the common themes I've seen among them is that there's usually some sort of warning sign or near miss that goes ignored by the people responsible for them since they don't cause any major damage. Then a few days or months later that system fails in an entirely predictable way with catastrophic consequences. A good example of this is the fatal phosgene gas release at a DuPont chemical plant[1].
It is worth keeping in mind that you don't see the other side of the equation in these reports: how many warning signs and near misses that didn't result in a major accident. Part of that is just the odds, and why people and organisations can become complacent to them, and part of it is that while most of them may be addressed, some can still slip through the cracks.
