ohutusklasse

Ohutusklasse, or safety class, is a category used to describe the level of safety required or guaranteed for a product, system, or environment. It expresses the degree to which protective measures, design features, and testing demonstrate resilience against hazards and compliance with safety standards. The concept helps manufacturers, regulators, and users understand the risk level and the precautions needed during installation, operation, and maintenance.

Common contexts for ohutusklasse include electrical equipment, protective equipment, and construction or industrial processes. In electrical equipment, safety classes indicate protective measures: Class I appliances have protective earth and basic insulation; Class II appliances rely on double insulation and do not require an earth connection; Class III devices operate at low voltage (SELV) and are designed for safety labeling. Other contexts involve the categorization of protective gear and building safety requirements, as well as classifications of hazardous substances or processes.

Determination of a safety class is typically based on risk assessment and compliance with applicable standards. Standards and regulations define the criteria for each class, and testing, verification, and documentation are used to assign the appropriate ohutusklass. Labeling and accompanying user instructions communicate the applicable class and any required precautions or maintenance.

Regional usage varies, but in Estonian-language documents the term ohutusklasse or ohutusklass is used to denote these safety levels. The exact criteria and terminology may differ between sectors and standards, and the concept is complemented by sector-specific classifications and compliance schemes. This ensures clarity in safety obligations for manufacturers, regulators, and end users.
