Tulenarkaita

Tulenarkaita is a Finnish term used to describe substances that are easily ignited; in English, flammable materials. The word combines tuli meaning fire and arka meaning sensitive, and the plural form tulenarkaita is used in safety, regulatory, and industrial contexts.

Scope and classification: In safety documentation such as material safety data sheets and shipping documents, tulenarka aine refers to flammable substances. The term aligns with international systems like the GHS and CLP, which categorize substances based on properties such as flash point and ignition risk. The exact thresholds and categories vary by whether the material is a liquid, solid, gas, or aerosol and by national regulations, but the core idea is to identify substances that require special handling to prevent ignition.

Handling and storage: Tulenarkaita must be stored away from heat sources, sparks, open flames, and static discharge. They are typically kept in tightly closed containers and, where appropriate, in fire-resistant cabinets. Adequate ventilation, grounding, and proper fire-fighting equipment are recommended, along with procedures for accidental spills and exposure.

Examples: Common tulenarkaita include fuels such as gasoline and solvents like acetone and ethanol, as well as paints, varnishes, adhesives, and many aerosol products. These materials pose ignition risks under normal handling and storage conditions and require appropriate safety measures.

Context and usage: In Finland, the term is used across occupational safety, fire protection, and transport of dangerous goods, reflecting the national adoption of EU CLP/GHS labeling and classification practices. The concept is widely understood by professionals involved in chemical safety, risk assessment, and compliance.
