polttokelpoista

Polttokelpoista refers to the property of a material that allows it to ignite and sustain combustion under certain conditions. In Finnish safety and regulatory language, it is a key descriptor of flammability or combustibility. The term is used to categorize substances and mixtures for safety data sheets, product labeling, storage, and handling guidelines.

In practice, polttokelpoisuus is assessed through standardized tests that determine a substance’s flammability characteristics. The most common is the flash point, the lowest temperature at which vapors can ignite in the presence of an ignition source. Other relevant properties include the autoignition temperature and the flammable or fire-exposure range. These measurements underpin regulatory classifications and labeling under systems such as the European Union’s CLP Regulation and the Globally Harmonized System.

Regulatory and safety implications follow from the classification. Polttokelpoisia materials require precautions to prevent ignition: separation from heat and sparks, adequate ventilation, proper containers, and appropriate storage and handling procedures. Labels and safety data sheets communicate flammability risks and recommended controls to workplaces and consumers alike.

Examples of polttokelpoisia substances include common solvents and fuels such as ethanol and various hydrocarbons. Substances with high resistance to ignition or that do not form ignitable vapors are regarded as less polttokelpoisia. The term thus helps convey fire hazard potential in a clear, standardized way across products and environments.
