Question

Difference between individual risk and societal risk

Answer 1

Risk can be addressed from many different angles. With individual risk, one person is exposed to one or more hazards. Individual risk calculations are normally performed when considering a plant employee exposed to plant hazards. In contrast, with societal risk, a group of people is exposed to one or more hazards. Societal risk calculations are normally performed when considering the risks to a community surrounding a chemical plant and exposed to multiple plant hazards.

• Technical risks are those events or issues associated with the scope definition, research and development (R&D), design, construction, and operation that could affect the actual level of performance vs. that specified in the project mission need and performance requirements documents.

• Schedule risk is the risk associated with the adequacy of the time allotted for the planning, R&D, facility design, construction, and startup operations.
