![]() Hence, we can prevent accident by either eliminating the hazard if possible, eliminate the hazard state or controlling the exposure.īase on the pictogram, BLOCK EXPOSURE then the chain is shattered. ![]() This gives us more window in accident prevention. Hazard can also be defined base on STATE.Īt this point you will agree with me that the salient actor within the chain is EXPOSURE. Without EXPOSURE there is no risk and without EXPOSURE there can never be accident. Hazard is a complex term which could be analyzed from different angle. For instance, a nail inside a tool box is a hazard because it has the potential to cause injury, an over speeding car on the road is a hazard because it has the potential to cause an accident, uneven edge of a container is a hazard because it can cause laceration, none of these will cause accident except someone is exposed to them, but is does not mean they are not there. If you look around, there is always a thing, a situation or a condition that could bring harm from you. Recall the definition of hazard: Hazard is anything, situation or condition which has the potential to cause harm to people, equipment and environment. ![]() The frequency with which each of the different types of accident occurs are based on a review of accident records over the period 19842007. I know some persons will disagree with me when I say “Hazards are constant most times”, but I will explain why I say that. This basic risk model will provide a quantitative estimate of the probability of an overrun accident reaching a defined distance beyond the runway end. Hence in accident prevention, what we do often is that we either eliminate the hazard if possible or block exposure. First, I want us to have an understanding that hazard most times is a constant. ![]()
