Turvallisuusaste

Turvallisuusaste is a Finnish term used to describe the safety level of a system, product, or process. It indicates how well hazards are mitigated and how effectively risks are reduced to an acceptable level. The concept can be expressed on qualitative scales (for example low, medium, high) or on numerical scales, depending on the context and the standards in use. In some technical fields, the term may be linked to specific safety frameworks such as safety integrity levels or performance levels.

Determination of turvallisuusaste generally follows a risk assessment process. This includes identifying potential hazards, estimating the severity and likelihood of harm, and evaluating existing protective measures. Based on this analysis, additional safeguards may be specified to achieve a desired safety level. Standards and regulations guide the assignment of turvallisuusaste and may prescribe required levels for particular applications or industries.

Applications and relevance span multiple sectors. In machinery and industrial automation, turvallisuusaste relates to how safety features, guards, interlocks, and control systems reduce residual risk. In electrical installations, construction, transportation, and consumer products, the term is used to communicate expected safety performance and compliance to regulators, manufacturers, and operators.

Limitations include dependence on use context and environment. A stated turvallisuusaste reflects assumptions about operating conditions and maintenance; changing conditions can alter the actual safety performance. Therefore risk management is an ongoing process, not a one-time rating.
