Lung disease is directly related to specific risk factors such as cigarette smoking and working in occupations that carry risks for developing lung disease. Plastics, wood, metal, and textile workers, bakers, millers, farmers, poultry handlers, miners; grain elevator workers, laboratory technicians, drug manufacturers, dry cleaners, and detergent manufacturers are all exposed to airborne agents that can cause occupational asthma, lung cancer, and other respiratory disorders.

Your lungs have a limited capacity to protect themselves against many different types of irritants. No smoking and avoiding exposure to tobacco smoke are critical to protecting your
lungs. Cigarette smoke is the major cause of lung cancer, chronic bronchitis, and emphysema. Exposure to cigarette smoke also increases your risk of respiratory infection.

If your job exposes you to airborne irritants, be sure to wear a protective mask or, if needed, a respirator to prevent inhalation of those hazardous substances. Be familiar with the information and recommendations contained in the material safety data sheets for all of the hazardous substances you may be exposed to at work.

Keep your home well ventilated to prevent the accumulation of carbon monoxide or other harmful gases and to prevent mold and fungi from growing inside. Clean air conditioners, humidifiers, dehumidifiers, and air purifiers regularly to reduce your exposure to dust, mold spores, and other irritants and allergens.
