A specific form of asthma called occupational asthma is brought on by inhaled irritant exposure during work. Since occupational asthma frequently has a reversible course, avoiding the triggers may cause the symptoms to go away.

Inhaling compounds referred to as triggers might cause asthma symptoms in people with sensitive airways. Several industrial chemicals can cause asthma symptoms, which can result in occupational asthma. The most frequent triggers include chemicals, fungi, animal dander, wood dust, grain dust, or grain dust.

Symptoms of occupational asthma include wheezing, shortness of breath, runny nose, nasal congestion, eye discomfort, and tightness in the chest. When exposed to the irritant(s) at work, these symptoms may develop worse.
