PPE is your last line of defence, mentoring them to understand working safe is of greater benefit to them and their families takes time but can be taught its a matter on how you teach them. We use toolbox talk and JHA reviews every morning before they start work and give out prizes for the most safest crew of the week. One of our most sucessful talks was to have ten guys come up to the front of the group some we blindfolded some we taped their hands up to simulate different injures etc etc then asked them to tie their shoes, you just have to make it interactive in order to make them think about it.
