Introduction to Hazard Risk Assessment

WithLouis Theodore, R. Ryan Dupont

Risk assessment of accidents serves a dual purpose. It estimates the probability that an accident will occur and also assesses the severity of the consequences of an accident. Consequences may include damage to the surrounding environment, financial loss, injury, or loss of life. The causes of accidents have to be identified in order to help prevent accidents from occurring. Any situation or characteristic of a system, plant, or process that has the potential to cause damage to life, property, or the environment is considered a hazard. Hazard or event identification provides information on situations or chemicals and their releases that can potentially harm the environment, life, or property. Information that is required to identify these chemical hazards includes chemical identities; quantities and location of chemicals in question; and specific chemical properties such as boiling points, ignition temperatures, and toxicity to humans.
