When is a Risk not a Risk?

Understanding the Difference Between Hazards and Risks

In the discipline of risk management, a common conundrum often arises: “When is a risk not a risk?” This question underscores the vital distinction between two key concepts – hazards and risks. While they are closely related and often used interchangeably, understanding their differences is crucial for effective risk management strategies. Here’s our take on the subject:

Defining Hazards and Risks

Let’s first define what we mean by hazards and risks:

  • Hazards: A hazard is any source of potential damage, harm, or adverse health effects on something or someone under certain conditions. Hazards can be physical, such as a slippery floor; chemical, like a toxic substance; or even environmental, such as a flood-prone area.
  • Risks: Risk, on the other hand, is the chance or probability that a person will be harmed or experience an adverse health effect if exposed to a hazard. It also pertains to the extent of the potential damage.

When a Hazard is Not a Risk

The key to distinguishing when a hazard is not a risk lies in the context of exposure and probability. A hazard becomes a risk only when there is a likelihood of it causing harm in a specific context. For example, a highly toxic chemical is a hazard, but if it is securely contained and handled with appropriate safety measures, the risk of it causing harm is significantly reduced.

Scenario-Based Understanding

Consider a mountainous terrain; it is a hazard for hikers due to its potential for causing injuries. However, for an experienced hiker with the right equipment and knowledge of the terrain, the risk might be minimal. In contrast, for an inexperienced hiker without proper gear, the same terrain presents a much higher risk.

The Role of Control Measures

Control measures play a crucial role in transforming a hazard into a ‘non-risk.’ Implementing robust safety protocols, training, and emergency preparedness can effectively mitigate the risks associated with a hazard.

For instance, electricity is inherently a hazard due to its potential to cause shock or fire. However, in a home with proper electrical installations, safety switches, and routine maintenance, the risk of an electrical accident becomes negligible.

Misconceptions and Mismanagement

A common misconception in risk management is overestimating or underestimating the difference between hazards and risks. Overestimating risks can lead to unnecessary precautions and resource allocation, whereas underestimating them can result in inadequate safety measures.


Understanding the nuanced difference between hazards and risks is essential in risk management. A hazard poses a potential threat, but it is the context, likelihood, and severity of the outcome that determines whether it is a risk. This distinction is crucial for prioritizing safety measures, allocating resources effectively, and maintaining a balanced approach to managing potential dangers. In essence, recognizing when a risk is not a risk is fundamental to creating safer, more efficient, and resilient environments.
