May have posted this before.....anyway....
Here's a link to the IChemE paper on the subject.

In my opinion the writer takes a slightly cold view of the events. Yes the Company was fined £130,000 but they are keen to point out that this was a reduced amount after the court took into account the employees negligence in not following procedures. Bear in mind that these were basically uneducated labourers who could barely read and write in English and that the shortcuts in procedure which led to the explosion had been going on for some time, years probably, so yes they contributed to their own demise but then you might also feel that the Company should have had more control over the operation. Certainly if the accident happened today the Company would be crucified for failing to ensure the safety of men who couldn't be trusted to either understand or follow basic instructions.
A friend of mine's father, a doctor, was also the medical officer at the plant at the time. He had the unenviable task of collecting and identifying various feet, fingers, eyeballs etc following the explosion so perhaps his opinions on the matter have clouded my opinion too....
