Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Diagnosis

History: Malignant mesothelioma sufferers may report chest pain, shortness of breath (dyspnea), loss of appetite (anorexia), increased perspiration, weight loss, fatigue, cough or fever. Bone and joint pain, swelling, and arthritis may also be reported. The individual may report a history of asbestos exposure (35 to 40 years previously). LFTP patients often have no symptoms, but a few report the same symptoms as malignant mesothelioma.

Physical exam: Physical findings may include recently diminished breath sounds indicating fluid in the chest cavity, shortness of breath (dyspnea), and cough. Individuals with stage III or IV cancer may additionally experience abdominal pain and nausea. Some individuals may have broadening and thickening of the ends of the fingers (clubbing) that is associated with lung (pulmonary) disease. Rarely, patients may present with neurological problems.

Tests: Malignant mesothelioma usually appears as diffuse, nodular, pleural thickening as seen on chest x-ray. X-rays may also show the presence of fluid in the chest cavity (pleural effusion), which occurs in 50% of individuals with mesothelioma and in 17% of those with LFTP (Tan; Meziane). Less commonly, an isolated tumor mass may be also seen on x-ray.

CT, MRI, and positron emission tomography (PET) scans may be performed to determine the extent of the disease. Tissue samples (biopsy) may be taken by means of needle aspiration or surgical excision to evaluate the tissue under a microscope. Other helpful tests include complete blood count (CBC), metabolic panel, thoracoscopy, and pleuroscopy to finalize the diagnosis. A ventilation and perfusion (V/Q) scan can be obtained to evaluate function of the lung.
