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.

Overview

Pregnancy is the condition of having a developing embryo or fetus in the body as the result of the union of an ovum and spermatozoon (conception). Pregnancy can occur anytime after a female begins menstruating (menarche) until she reaches menopause. However, most pregnancies occur in women ages 15 to 40 years. Pregnancies before the age of 15 and after the age of 35 have an increased risk of complications.

The first indication of a pregnancy usually is a missed menstrual period. Laboratory tests or home pregnancy test kits check for human chorionic gonadotropin (hCG) in the woman’s serum or urine; hCG is a hormone produced by the placenta. After confirmation of the pregnancy, the physician, with information from the mother, can determine an approximate date of birth. The length of pregnancy averages 270 days from fertilization but normally is counted from the first day of menses prior to conception (approximately 284 days). Thus, the gestational age of the fetus is two weeks less than the number of weeks a woman is considered pregnant.

The growth and development of the fetus is affected by many aspects of the mother’s health: nutritional status; use of drugs, alcohol and cigarettes; use of prescribed medications, herbal remedies, and dietary supplements; medical conditions; age at time of pregnancy; and prenatal care.
