Hazardianalüüsist, also known as hazard analysis, is a systematic process used to identify and evaluate potential hazards associated with a system, product, or process. The primary goal of hazard analysis is to ensure the safety and reliability of the system by identifying and mitigating risks before they occur. This process is crucial in various fields, including engineering, manufacturing, and healthcare, where the potential consequences of failure can be severe.

The hazard analysis process typically involves several key steps. First, a comprehensive understanding of the system or process is developed. This includes identifying all components, their interactions, and the operating environment. Next, potential hazards are identified through various methods, such as brainstorming sessions, failure mode and effects analysis (FMEA), and fault tree analysis (FTA). These methods help in systematically identifying all possible failure modes and their potential effects.

Once hazards are identified, they are evaluated to determine their severity and likelihood. This evaluation often involves assigning risk levels based on factors such as the probability of occurrence and the potential impact on the system or process. The results of this evaluation are used to prioritize hazards and develop mitigation strategies.

Mitigation strategies aim to reduce the risk associated with identified hazards. These strategies can include design changes, operational procedures, safety measures, and monitoring systems. The effectiveness of these strategies is continuously monitored and reviewed to ensure they remain adequate over time.

Hazard analysis is an iterative process, meaning that it is repeated as the system evolves or as new information becomes available. This ensures that the system remains safe and reliable throughout its lifecycle. By systematically identifying and mitigating risks, hazard analysis plays a critical role in preventing accidents, reducing downtime, and enhancing overall system performance.
