A Severity Scale is a tool used to categorize the intensity or seriousness of an event, condition, or issue. It helps in assessing risks, prioritizing responses, and making informed decisions. Commonly used in fields like healthcare, emergency management, and environmental science, the scale typically ranges from low to high severity, allowing for clear communication about the level of concern. For example, in healthcare, a severity scale might classify symptoms of a disease from mild to critical, guiding treatment options. In emergency management, it can help determine the urgency of response needed during a natural disaster, such as a hurricane or earthquake.
