My doubt is very basic.. We(safety people) analyze the situation and come out with some effective methodology or PPE to minimize the hazards. Next challange is implementation. Even if it is implemented,there are people who still show their experience and avoid PPE(ie. I am working in this field for 5 years without accident.. something like that). How to make this kind of people realize the importance of our implementation? Is penality or enforcement the only way? Can anyone say an effective method of influencing the workers? Please guide me.. Thank you in advance..
