A Safety Attitude Safety is not often thought about as we

proceed through routine daily tasks. Often we all expose ourselves to needless risk because we have gotten away with it and so far no harmful effects have resulted. However, in a potentially hazardous job environment, your career and perhaps even you life may indeed rest on safe work habits and adopting a safety attitude not only at work but in everything that you do.
