Pölytehosteet

Pölytehosteet is a Finnish term used in industrial and scientific contexts to describe substances or methods intended to increase the generation or suspension of fine particulates (dust) from a material. The term is not standardized, and its precise meaning varies by field and purpose. In general, pölytehosteet can refer to equipment settings, environmental conditions, or chemical or physical additives that promote dust release or lofting of particles.

Applications include testing and evaluation of air sampling equipment, respiratory protective devices, and ventilation systems, where controlled dust generation is necessary to assess performance under representative conditions. They are also used in materials handling research to study dust control, as well as in safety testing such as dust explosion hazard assessments. Methods may involve mechanical agitation (for example milling, conveying, shaking), controlled humidity and temperature, and, in some cases, chemical or surface treatments that reduce particle cohesion or alter moisture adsorption.

Safety and regulatory considerations are central: dust can pose inhalation hazards and, in some forms, explosive risks. Use of pölytehosteet requires appropriate risk assessment, adherence to occupational safety regulations, and proper containment, exhaust, and personal protective equipment.

Etymology: from pöly (dust) and tehosteet (boosters, intensifiers). See also dust, aerosol, filtration testing, dust explosion hazards.
