Which statement best defines a hazard?

• A. Hazard: rare and extreme event, or the probability of an occurrence in the natural and human-made environment that adversely affects the success of the project to the extent that it may cause economic, time, infrastructure, or resource loss.
• B. Vulnerability: degree of loss to a given element that is possible risk from the impact of a hazard of a given severity.
• C. Risk: the probability that a risk event will occur.
• D. Frequency: number of times a particular risk can impact a project.

Answer: (A)

Hazard is a potential source of harm in the environment that could affect a project. The statement captures this by describing a hazard as a rare or extreme event, or the probability of an occurrence, that in natural or human-made settings could adversely impact the project and lead to losses in time, money, infrastructure, or resources. It focuses on what could cause damage, not on how likely it is or how badly it would affect us once it happens. Vulnerability refers to how susceptible or exposed the project is to damage once a hazard occurs, not the source of harm itself. Risk combines both the likelihood of a hazardous event and the magnitude of its impact, rather than just the source of harm. Frequency deals with how often events might occur, which is a separate consideration from the hazardous source itself. So the statement best defines a hazard.
