A proactive methodology for accident prevention, called Continuous Hazard Tracking and Failure Prediction Methodology (CHTFPM), has been developed by utilizing the principles of work sampling and control charting. Sampling is performed to observe the occurrence of conditions that may become hazardous in a given system. These conditions, known as dendritics, could eventually result in an accident or occupational disease. The CHTFPM involves a random sampling for the occurrence of these dendritics. The collected data is then used to generate a control chart. Based on the pattern of the control chart, a system “under control” is not disturbed whereas a system “out of control” is investigated for potential conditions becoming hazardous. Appropriate steps can then be taken to eliminate or control these potentially dangerous and costly conditions to maintain a safe system
