TS 12940

TS 12940 is a professional standard for chimney cleaners, defining the occupational role of the person who carries out chimney cleaning in homes and workplaces, together with the qualification framework and tools associated with the job. In technical terms, chimney cleaning is not just routine maintenance; it is a specialized task connected to the safe removal of combustion by-products and to the proper function of flue systems.

Technical context of the occupation

From a general engineering and building-services perspective, chimney cleaning deals with soot, ash, creosote-like deposits, and other residues that can accumulate inside a flue. Clearing these deposits helps maintain draft, supports efficient exhaust of smoke and combustion gases, and reduces the risk of blockages that can interfere with heating appliances. The work is commonly relevant to stoves, boilers, fireplaces, and similar heating installations where the flue path must remain open and serviceable.
