Yes, safety is very boring but the way companies are going now its a massive thing (certainly in the bigger companies anyway). Thought because I have the IOSH MS I could do the NEBOSH and like you say DCI its an extra line on the CV and there seems to be some decently paid jobs out there that require it (currently in contract managements for a logistics co)
Theres a place in Manchester that do it over 13 days, two blocks of five with a week inbetween blocks, then a block of two for revision then exams etc on the final day (one day after the block of two)
The IOSH MS was bad enough staying awake and that was only a 4 day course but again split into blocks of 2x2. And why is it there is always someone in the group who questions the tutor
