What health risks are associated with dust exposure?

• A. Can irritate eyes, nose, throat, and skin, and pose a relatively high inhalation exposure risk to handlers.
• B. Dust exposure has no health risks.
• C. Dust exposure only causes temporary skin redness.
• D. Dust exposure improves respiratory function.

Answer: (A)

Dust exposure carries real health risks because those tiny particles can affect both the eyes, nose, throat, and skin, and can be inhaled deep into the lungs. When workers encounter dusty materials, the particles can cause immediate irritation of mucous membranes and skin—think red, itchy eyes; a sore or irritated throat; a runny nose; and skin reactions. At the same time, inhaling fine dust increases the chance of respiratory symptoms such as coughing, wheezing, and breathing difficulty, and with repeated exposure it can contribute to longer-term problems like bronchitis or asthma. This combination of irritant and inhalation risks is exactly what is described in the correct choice. The other options either deny any risk, limit the effect to just temporary skin redness, or wrongly claim that dust exposure improves respiratory function.
