Ohutustähtsad

Ohutustähtsad are safety-critical components or systems. In engineering and product design, certain parts or functionalities are designated as "ohutustähtsad" when their failure could lead to significant harm, such as injury, death, or substantial property damage. The concept is fundamental to developing safe and reliable products across various industries, including automotive, aerospace, medical devices, and industrial machinery.

The identification of ohutustähtsad elements involves a thorough risk assessment process. This process typically analyzes potential failure modes and their consequences to determine the level of safety criticality. Components or systems deemed ohutustähtsad are then subject to rigorous design, manufacturing, testing, and maintenance standards. This often includes redundancy, fail-safe mechanisms, and stringent quality control measures to minimize the probability of failure and mitigate the impact of any failures that do occur.

International standards, such as ISO 26262 for automotive functional safety or IEC 61508 for functional safety of electrical/electronic/programmable electronic safety-related systems, provide frameworks for managing the safety lifecycle of ohutustähtsad. Adherence to these standards is crucial for manufacturers to ensure that their products meet the necessary safety requirements and comply with regulatory obligations. The goal is to achieve a defined level of risk reduction, ensuring that the likelihood of hazardous events is acceptably low.
