I liked an article that was published in British Safety Council magazine (http://www.britsafe.org/). In it the Chief Executive of First Group Plc states their approach to accident prevention as below:
If you can'g do it safely, don't do it.
To improve the safety record, their new approach is "First to Zero" to eliminate all unsafe conditions. The target is not at accident numbers but to focus on persons representing these safety numbers. They do not want anyone to get injured and thus aim for eliminating all unsafe conditions. Really, we have to salute the managers and staff for aiming to such a high standards and working towards it.
