Alternative Names
Occupational bronchitis
Causes, incidence, and risk factors
Exposure to dusts, fumes, strong acids, and other chemicals in the air causes this type of bronchitis. Smoking may also contribute.
You may be at risk if you are exposed to dusts such as:
- Asbestos
- Coal
- Cotton
- Flax
- Silica
- Talc
Symptoms
- Increased cough that brings up mucus (sputum)
- Shortness of breath
- Wheezing
Signs and tests
The health care provider will listen to the lungs using a stethoscope. Wheezing sounds may be heard.
Tests include:
Treatment
The purpose of treatment is to avoid the substance that is causing the irritation.
Getting more air into the workplace or wearing masks to filter out the offending air particles may help. Some cases of industrial bronchitis go away without treatment. Other times, a person may need inhaled anti-inflammatory medications.
If you are at risk or have experienced this problem and you smoke, stop smoking.
Supportive measures include:
- Breathing humidified air
- Increased fluid intake
- Rest
Expectations (prognosis)
The outcome may be good as long as you can stop being exposed to the irritant. Chronic disability from industrial bronchitis is rare.
Complications
Continued exposure to irritating gases, fumes, or other substances could lead to permanent lung damage.
Calling your health care provider
Call your health care provider if you are regularly exposed to dusts, fumes, strong acids, or other chemicals that can affect the lungs and you develop symptoms of bronchitis.
Prevention
Control dust in industrial settings by wearing face masks and protective clothing, and treating textiles. Stop smoking if you are at risk.
Get early screening by a doctor if you are exposed to chemicals that can cause this condition.
