Maybe worth sharing an observation from my building endeavors in Cambodia: often the workers don't realize the risks they are taking, so before lobbying for decent standards, they often need to actually comprehend what they are. This can be more difficult to get through to them than you might think. For example getting welders to always wear eye protection, getting people spray paint for a living to do so in a properly ventilated space. You can try to explain to them the risks - and buy them all the stuff - but many of them will just ignore you and do it the "sensible way without all that silly overhead".
