When we look at the terms of risk reduction and hazard control we get the terms of eliminating and reducing the issues. Where control of hazards seek to maintain instead of removing the process. The term that risk reduction is applied to is a complete understanding of the intent of the criterion to ty risk- reducing the probability of the events occurring. In the terms of the second and third definitions of risk because they include both the probability of the event and the severity of
