Emerging technologies and processes, such as nano and green technologies, sustainable processes, and additive manufacturing processes, have led to the development and handling of "novel" materials, which pose significant safety issues as they exhibit properties different from those of commonly used materials. The main differences are related to the particle size (from micro to nano), shape (non-spherical), density and structure (porous particles), and composition (metal alloys and hybrid mixtures). Data on flammability and explosion behavior, as well as standard procedures and equipment derived for spherical dust with micro size, cannot be directly applied to these emerging materials. In this chapter, the main literature findings on the flammability and explosion behavior of hybrid mixtures, non-spherical dust, nanomaterials, and additive manufacturing dust are discussed

Abstract
Emerging technologies and processes, such as nano and green technologies, sustainable processes, and additive manufacturing processes, have led to the development and handling of "novel" materials, which pose significant safety issues as they exhibit properties different from those of commonly used materials. The main differences are related to the particle size (from micro to nano), shape (non-spherical), density and structure (porous particles), and composition (metal alloys and hybrid mixtures). Data on flammability and explosion behavior, as well as standard procedures and equipment derived for spherical dust with micro size, cannot be directly applied to these emerging materials. In this chapter, the main literature findings on the flammability and explosion behavior of hybrid mixtures, non-spherical dust, nanomaterials, and additive manufacturing dust are discussedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
