Description
The author summarizes todays knowledge of the cause and consequences of dust explosions which were the main focus of his professional life. The presence of explosible dust/air mixtures does not generally represent a risk of an explosion although all organic and metallic dusts are explosible. The author develops test-methods for explosion hazards associated with dust and constructive methods to prevent dust explosions. The book is written for practical use. The reader learns to recognise the hazard of a dust explosion and the effectiveness of safety measures. The book is richly illustrated and demonstrates the correct use of the empirical theories.
