Overview
Risk Factors
- Asbestos exposure occurs most commonly in the workplace.
- Miners and millers of asbestos are at risk, but at even greater risk are people exposed during manufacturing and construction.
- Maintenance, repair, and removal of asbestos-containing material can also result in significant exposures.
- The health risk to building occupants where asbestos is in good repair and undisturbed is thought to be insignificant.
- Occupational Safety & Health Administration (OSHA) regulations require special precautions in areas where the concentration is > 0.2 fibers per cubic milliliter of air.
- About 8% of asbestos workers will die of respiratory failure secondary to asbestosis, and asbestos workers have a 50% chance of dying from malignancy (versus 18% chance for the average American).
- Asbestosis is a slowly progresive disease, so only a subset of patients progress on to respiratory failure.
- Risk factors for progression include:
- Cumulative exposure
- Duration of exposure
- Degree of symptoms
- Cigarette smoking
- Diffuse pleural thickening
- Honeycombing on high-resolution computed tomography (HRCT)
- High concentrations of inflammatory cells on BAL
- Risk factors for progression include:
