Abstract and keywords

Abstract (English):
The results of research of structure, composition, range scattering and fire danger hot particles generated during cutting inorganic building materials abrasive cutting circles angle grinding machines. In the process of research methods have been used scanning electron microscopy, elemental analysis and infrared spectroscopy. It is established that the probability of fire exists within the range of dispersion of friction sparks up to 2 m horizontally from the place of work. The presence within a local domain of materials prone to self-sustaining smudging, dramatically increases the likelihood of burning and its development.

Keywords:
friction sparks, stone inorganic material, fire risk, angle grinder
