Silicosis/Coal Workers’ Pneumoconiosis - Pulmonology Advisor

What every physician needs to know: Coal workers’ pneumoconiosis (CWP) and silicosis are preventable occupational lung diseases that are typically associated with significant dust exposure. Although these diseases are two separate entities, they may occur concomitantly, especially in coal miners. Despite mandated dust controls, silicosis and coal workers’ pneumoconiosis remain

tis in miners. “Coal dust particles are very reactive, including the chemical bonds on the surface,” Petsonk explains. “They will interact with anything nearby, including the body’s tissue, which creates an inflamma-tory response.” It’s the smaller respirable dust parti-cles, though, that create the damage most associated with CWP.

Respiratory Diseases Caused by Coal Mine Dust

In 1983, a sentinel case of acute silicosis was reported in a surface coal mine driller. 28 The case report included reanalysis of surveillance conducted in US surface coal miners in the early 1970s showing that drill crew workers were at significantly increased risk for pneumoconiosis relative to other surface coal miners. Medical examinations ...

Silicosis. Silicosis is caused by inhalation of unbound (free) crystalline silica dust and is characterized by nodular pulmonary fibrosis. Chronic silicosis initially causes no symptoms or only mild dyspnea but over years can advance to involve most of the lung and cause dyspnea, hypoxemia, pulmonary hypertension, and respiratory impairment.
