Abstract: In this paper, the explosion characteristics and explosion risk classification of wood fiber dust from the dust collector of a wood processing factory were investigated. Combined with explosion characteristic parameters, the risk level of wood fiber dust is strong according to the American Explosion Index E Comprehensive Classification Method; the explosion grade is St1 (weak explosion) based on the German Hazard Classification Method. While according to the International Electrotechnical Commission (IEC) Classification Method, the wood fiber dust does not require special attention. In China, the wood dust is classified as a high risk level flammable dust. However, we need to design and modify the explosion-proof devices according to the dust explosion parameters from the actual production process.

Key words: wood fiber dust, explosion characteristics, explosion risk classification
