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.

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.

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.

Factors Influencing Duration

Length of disability may be influenced by the severity of the illness, location of wounds, promptness and adequacy of treatment, presence of complications, and age of the individual.

Medical Codes

ICD-9-CM:
037 - Tetanus

Treatment

Tetanus infection is serious and life-threatening. Treatment is usually administered in the intensive care unit (ICU) of a hospital and has four goals: stabilization and support of the patient as symptoms develop, administration of tetanus immunoglobulin (TIG) to help moderate the effects of the toxin, administration of antibiotics to kill the C. tetani bacteria, and prophylactic immunization to prevent future occurrence.

An open airway must be maintained. Depending on the individual's symptoms, this may be done by different methods. A tube may be inserted into the windpipe (trachea) in a procedure called intubation. However intubation is difficult as a consequence of laryngeal muscles spasm, and the presence of an endotracheal tube may be a stimulus for further spasms; hence, in severe cases an artificial opening in the trachea (tracheostomy) may be required. If the individual is unable to breathe independently, ventilation may be required. Nutritional support may need to be provided through a feeding tube or through parenteral (intravenous) nutrition. The wound is cleaned thoroughly; damaged tissue may need to be surgically removed (débridement). Antibiotics such as metronidazole are administered to eradicate the toxin-producing organisms. TIG is also administered to neutralize unbound (free) toxin (antitoxin can't neutralize toxin already bonded to nerve tissue). Anticonvulsants may be necessary to control the seizures. Muscle relaxants and sedatives may also be prescribed.

Prophylaxis against pneumonia, deep-vein thrombosis (DVT), and thromboembolism is essential.

Because having tetanus does not grant further immunity against the infection, after recovery the individual should receive the full series of vaccinations.
