Incense is an indispensable material with religion and life in Asia. It is also a bridge of cultural expression and inheritance. Because the operating environment concentration of dust generated during the production process is considerable, most of the research pertaining to the hazard of incense factories has investigated air pollution, such as PM2.5, PM10, and VOCs. However, the production of incense causes dust dispersion, high temperature from ovens, and static electricity generated by friction. It can all possibly lead a dust explosion. To prevent and alleviate hazard from re-occurring, we used sandalwood dust at an incense factory in Taiwan, measured the effect of moisture content on the explosion parameters under normal conditions by 20-L apparatus, and used the oven to diminish its moisture content to 0%, 10.0%, and 15.0% as a control group to analyze the explosion characteristics at the different moisture contents, such as maximum explosion pressure and explosion limit. The results showed that the minimum ignition energy of dry dust was 30 mJ. Beyond doubt, incense factories face potential explosion hazards. The above results could be evaluated by the most dangerous range to avoid incense dust in this range at the workplace, lessening hazards caused by a dust explosion. The effect of moisture content on the suppression of the dust explosion was explored.

“…Wood dust explosion accounts for a considerable proportion of dust explosion accidents in the world [7]. In plenty of industries, a large amount of wood dust is produced during wood processing, such as paper industry, incense factories, sawmills, and house construction, especially in the process of sanding and polishing.…”

“…Particle size distribution or granulometry of the dust is one of the most important factors (Vandličková et al, 2020). It has been studied the characteristics of wood dust explosions in the Hartmann tube and found that particle size and concentration of the wood dust affect the explosion (Pang et al, 2020;Khudhur et al, 2021).…”

“…Surface sanding is an important component of the process, producing smooth surfaces to ensure higher adhesion of applied impregnating agents, paints, and varnishes. The dust created during this process is deposited on floors, walls, and working surfaces in the production facilities and hinders the operation of rotating machine components [1][2][3]. Moreover, dust with particle sizes significantly smaller than 100 µm remains suspended in the air, posing health risks for workers and creating additional workplace risks by limiting visibility and increasing the risk of fire [4][5][6][7][8][9].…”

Fine Dust Creation during Hardwood Machine Sanding

et al. 2021

Wood dust generated during woodworking—particularly from hardwood species during sanding—poses a health and safety hazard to workers in the wood industry. This study aimed to determine the particle-size distribution of selected hardwood species and the content of fine particles in dust created during machine sanding, which pose the highest health and safety hazards in the woodworking industry. Six hardwood species were studied: black alder, European ash, common walnut, pedunculate oak, hornbeam, and European beech. The sieve analysis method was used to determine the particle-size distribution and article mean arithmetic particle diameter, and laser diffraction analysis was used to determine the finest particle content. Two size ranges were assumed: <2.5 μm and <10 μm. Beech dust had the smallest mean particle diameter. Dust from wood species used in the test had similar contents of fine fractions of particles. The average content of particles smaller than 2.5 µm in wood dust from the tested hardwood species did not exceed 1.9%. In terms of occupational exposure to wood dust, machine sanding conditions of hardwoods should be properly adjusted to limit the formation of large amounts of dust.
