What is a hazard associated with using dusts (D) in applications?

Using dusts in applications can pose severe inhalation hazards due to the fine particles that become airborne during use. When these dust particles are inhaled, they can pose serious health risks, especially to the respiratory system. This hazard is particularly critical in environments where protective gear may not be used, or when adequate ventilation is not available. Given their small size, dust particles can remain suspended in the air for extended periods, increasing the likelihood of inhalation.

In contrast, other options do not accurately represent hazards associated with dusts. Low visibility during application is typically more of a concern with liquid formulations that can create splashes or mists rather than dust. Nonabrasive properties do not relate to hazards but rather describe a characteristic of the dust, and stating that there are no residues left is inaccurate, as dusts can in fact leave residues after application, depending on their composition and the conditions of use.
