After the “Aug 2” Kunshan dust explosion (2014) and “June 27” Formosa Fun Coast dust explosion (2015), the Sate Administration of Work Safety (SAWS) formulated:
Catalogue of Combustible Dusts of Key Concern in Industry and Trade Sectors (2015)
Guide of Explosion Prevention and Protection Processes and Facilities in Combustible Dust Workplaces for Industry and Trade Sectors (Trial)
Combustible dusts are fine dusts, fibers, etc. which can burn or smolder in air, and can form explosive mixture with air at normal temperature and pressure. The Catalogue only collects explosive dusts of relevant high risks substances related to industry and trade sectors including metallurgy, nonferrous metals, construction materials, machinery, light industry, textile and tobacco.
