Ohutustasemete

Ohutustasemete are a set of safety levels used to describe the degree of safety or risk in a system, situation, or process and to indicate the corresponding protective measures required. The term is Estonian and derives from safety (ohutus) and level (tase). Ohutustasemete function as a framework for risk assessment, design choices, and regulatory compliance across different contexts.

Ohutustasemete are applied in a wide range of sectors, including manufacturing, construction, transport, healthcare, and environmental protection. They help determine which controls are needed, such as engineering safeguards, administrative procedures, training, labeling, and emergency planning. The levels are typically defined by criteria such as the likelihood and severity of harm, exposure, and potential consequences, and they guide decisions about equipment standards, work practices, and inspection regimes.

Labeling schemes for ohutustasemete vary by domain. They may use simple ordinal descriptions (low, medium, high), numbered scales (1–4 or 1–5), or color codes (green, yellow, orange, red). Although the concept is widespread, there is no universal global standard; definitions and thresholds differ between jurisdictions, industries, and standards organizations.

In practice, ohutustasemete support proactive risk management by clarifying required safety measures, informing certification and compliance processes, and shaping emergency preparedness. The term emphasizes preventive action and appropriate resource allocation to reduce the likelihood and impact of hazards.
