A fine sugar dust explosion can generate pressure in excess of 7 bar within enclosed process equipment in less than 100 milliseconds. On February 7, 2008, a catastrophic sugar dust explosion occurred in a refinery in the U.S. The explosion resulted in heavy casualties among the workers. Consequently, the company involved faced prosecution and suffered a huge financial loss.
Dust is fine particles of solid matter. It can consist of a wide range of materials, from pollution to human and animal cells, textile and paper fibers, etc. Dust can accumulate within a production area and become a health hazard. This is especially true for people with a weakened immune system. Other sources of dust and aerosols are condensing vapors from the production process itself. The accumulation of dust and aerosols in the production area may cause manufacturing QC problems. This leads to manufacturing rejection within high-end production processes when it persists.
Improper ventilation can make it difficult to enact indoor climate control. The indoor temperature, humidity, or pollutant level can make it unpleasant to work efficiently. Furthermore, improper ventilation causes uncomfortable working environments that may directly or indirectly influence workers and the quality of products manufactured. So, optimizing the indoor climate is essential to ensure long-term work efficiency and product quality.
