Wood dust typically has a KST value between 100 and 250 bar·m/s, but a dust test on a representative sample is essential for accurate risk assessment and safety planning.
The KST value of wood dust, which measures its explosibility, can vary significantly depending on factors like wood type, particle size, moisture content, and processing conditions. Wood dust typically falls within the moderate to high explosibility range, with KST values often cited between 100 and 250 bar·m/s, though some finely ground or particularly dry samples may exceed this range. Variations in species, resin content, or contaminants such as adhesives or finishes can further influence explosibility. Given these variables, relying on general KST ranges may not provide an accurate risk assessment for your specific operation. To determine the exact KST value and design appropriate safety measures, it is critical to conduct a standardized dust test on a representative sample of the wood dust generated in your facility. This ensures precise data for explosion protection systems, compliance with safety standards, and the mitigation of risks.
