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. 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.

Factors Influencing Duration

The length of disability may be influenced by the ability to identify and eliminate the causative agent, the effectiveness of the symptomatic treatment, plus the location, extent, and severity of reaction. Antihistamine medication may cause sedation.

Medical Codes

ICD-9-CM:
708.0 - Allergic Urticaria
708.1 - Idiopathic Urticaria
708.2 - Urticaria due to Cold and Heat; Thermal Urticaria
708.3 - Dermatographic Urticaria; Dermatographia; Factitial Urticaria
708.4 - Vibratory Urticaria
708.8 - Other Specified Urticaria; Nettle Rash; Chronic; Recurrent Periodic
708.9 - Urticaria, Unspecified

Prognosis

Most cases of urticaria resolve completely without complications. The wheals can last for several hours. Identifying and avoiding known trigger factors can help prevent allergic reactions in the future. Even if the trigger source cannot be identified, the allergic reactions can lessen in frequency and severity over time without treatment. In rare cases, a medical emergency may arise should severe anaphylaxis or severe respiratory tract angioedema develop; death is possible if that condition is not treated promptly. Even individuals with anaphylaxis, however, recover completely after treatment of the episode. Up to 20% of people with chronic urticaria can suffer with the disorder for longer than a decade (Sheikh).
