→Hazard Identification
==Hazard Identification==
==Hazard Identification==
A hazard can be defined as something that is potentially harmful- to humans, animals, plants or the environment. This could be the presence of a pathogenic organism in an item of food, faulty brakes in a car or an uncovered manhole. Hazard identification is thus the process of identyfying all possible hazards in a given situation. In reality it may not be possible to identify every hazard in existance for a given situation. However, in order to estimate the risk associated with a given hazard the hazard has to be identified in the first place.
#'''Risk Assesment.''' ''- covered in greater depth on [[Risk Assessment]] page.''<br>This refers to the evaluation of the risk(s) associated with a hazard. This often requires risk assessors skilled in a number of diiferent fields. Risk can be defined in this setting as the probability of an undesirable outcome occurring as a consequence of the hazard. This implies that there is more than one possible outcome that could occur and at least one of them is undesiable. In risk analysis the probable consequences of the undesirable outcome occurring are also estimated. For example, if the presence of a pathogenic organism in an item of food is the hazard, then the risk assessment would try to estimate the probability of that organism in the food item causing disease and if it did cause disease , how severe would the disease be & how many people would be affected. Some undesirable outcomes may only affect a few people but have severe consequences or affect many people but have an insignificant effect. Also different people may view a paricular outcome as more undesirable than other people. This is of importance in risk managemant & communication. '''See [[Risk Assessment]] for more detail.'''
