The holier-than-thou comments at the start of this thread were echoed in whatever flight safety publication I was reading about this issue, when RTFL was the officially mandated solution (along with: it's too difficult to change the contract now OR IN THE FUTURE).
There will always be ignorance between the trades but I had hoped that the better integration of the engineers and the suppliers over the past decade would have gone some way to mitigate and avoid these problems. Clearly, we still have a long way to go!
(Or in other words, if you haven't worked in the middle of nowhere, at oh-dark-thirty, outside, in the dark, with crappy lighting, low on manpower, under pressure to meet an op wave, after 12 hours plus on duty, then try to imagine how easy it is to make a mistake reading a label - if you can't, then you sound like the ideal man to go into POL procurement!)
