...the hazard and potential hazard will always exist out there...
As Safety Engineer, we have responsibility to prevent any accidents and losses that may happen in our plant. We are the person whom believed capable to control the hazard. In other side, as a normal human, do you believe that by our limitation is it possible to stop the hazard just like what we (or our company) want?.
To manage the potential loss(es) cause such as hazard and potential hazard is our job. It is off course possible to do. That is an achievable target. But, it is different with stop or eliminate the hazard or potential hazard. I told you, you will off course control the hazard by doing adequate hazard management programs. And reducing the risk level of accident and loss(es) that may happen. But remember, the hazard and potential hazard will always exist out there. That is way I say, Hazard is impossible to be eliminate. What we can do is control, a maximum effort is reducing the accident and loss risk. Because there is exact formula for us, wherever workplace exist, the hazard and potential hazard will always follow to appear there (workplace = human + tools + material = Output + Process + hazard).
