Lightning risk assessment for explosives sites taking into account zones 0, 1 and 2 and environmental risk

Abstract : The newest draft version of IEC/EN 62305-2 standard dealing with risk management includes the environmental risk in a much better way than before. It takes also into account all the explosives zones when only zones 0 and 20 where addressed before. Purpose of this paper is to show how these changes will modify the level of risk obtained with previous version of standard. The environmental risk is clearly more tailored to what is needed with version 2 of the standard even if it may lead to increased risk compared to before when insufficient data exist. When taking into account the explosives zones 1, 2, 21 and 22, the risk may increase even if the new method tends to reduce the risk globally. An example of use of storm detectors to reduce the risk is also given
