Dear Sir
Awaiting for your post with the perfect answer...
Adding one more point ot my answer please:
Lack of understanding the responsibility towards safety, may be one of the another reason. Because most of the workers, thinks that looking after safety and making the job safe; is the job of safety officers, supervisors & engineers. In this case they (workers) fail to understand the concept that safety is individuals responsibility. By providing quality PPE's to the employees the emploer is in safe side, now its their responsibility to make the right use of it. Simply can say the concept of "Accountability" to be percolated down the level, upto the worker. I think the concept of accountability, we have discuss in this same forum as a reply to one another posting of you.
With regards,
