Inhalation refers to breathing in substances in which forms? (Select all that apply)

Inhalation involves the process of breathing substances into the lungs, and it encompasses a variety of forms. Dust, which consists of fine solid particles, is a significant inhalation hazard because these particles can be suspended in the air and easily inhaled, leading to potential respiratory issues or toxic exposures.

While dust is one form, inhalation can also include other states of matter such as gas and vapor. Gases are substances that exist in the gaseous state at room temperature and can easily diffuse in the air, making them inhalable. Vapors are the gaseous forms of substances that are typically liquids at room temperature; they can also be inhaled when they evaporate into the air.

In summary, the correct understanding of inhalation encompasses multiple phases including dust, gas, and vapor, as each can be easily inhaled and pose health risks. Focusing solely on dust limits the broader understanding of inhalation hazards.
