Hands-on Activity Demonstration: Dust Generation

Many nanomaterials are produced as dry powders and have the potential to release particles to the air. The dustiness of a powder correlates to an increased risk of worker exposure and dust explosion hazards in the workplace. Among the factors that influence the dustiness of a powder in an occupational setting are the quantity and size distribution of the powder and the energy input of operations or tasks that stress the powder. The objective of this activity is to measure the influence of types of powders and drop height of a powder on the spread of particles through the air.
