This paper examines the critical distinctions between three foundational terms in insurance and risk management: peril, hazard, and risk. Drawing on definitions from Chew (2008) and Dorfman (2002), the paper explains that a peril is a cause of loss, a hazard is something that increases the probability of loss, and risk refers to the uncertainty or variation in possible outcomes. Through clear examples such as fire, floods, and smoking near gas stations, the paper illustrates why these terms — though commonly used interchangeably in everyday English — carry precise and distinct meanings within the field of risk management.
In common non-insurance settings, the terms "peril," "hazard," and "risk" are more often than not used synonymously. It is, however, important to note that in insurance — and most particularly in risk management — "hazards" and "perils" are not treated as synonymous with "risk," as they often are in everyday English. This paper concerns itself with the distinction between these key terms, and briefly considers the types of risks faced both as a student and as Vice President of a student council.
In seeking to distinguish these key terms, it is prudent to first consider how various authors have defined them. To begin with, a peril, in the words of Chew (2008, p. 35), is "a natural, man-made, or economic situation that may cause a personal or property loss." A hazard, by contrast, is defined by the same author as "something that increases the probability of a loss arising from a peril" (Chew, 2008, p. 35).
With regard to risk, Dorfman (2002) defines it as "the variation in possible outcomes of an event based on chance." Based on this definition, risk is simply the possibility, chance, or likelihood of loss.
On the basis of these definitions, perils include — but are not limited to — fire, heart attack (in the context of health insurance), tornadoes, lightning, and floods. Individually or collectively, these perils can bring about a loss, which is why they are identified as "causes of loss." For instance, when an entire commercial building is consumed by fire, fire is identified as the peril. Hazards, on the other hand, include things such as a thatched roof in an area susceptible to fire, or smoking near a gas station — conditions that heighten the probability of a loss occurring.
