Inputs: Occupational Safety and Health Risks
U.S. Department of Labor, Bureau of Labor Statistics, Injury, Illness, and Fatality Program
The U.S. Bureau of Labor Statistics (BLS) publishes detailed information about occupational injuries, illnesses, and fatalities from private industry. Results of the 2013 survey revealed 1,162,210 nonfatal cases involving days away from work (109.4 cases per 10,000 workers), down from 2012 in which 1,181,290 total cases (117.3 per 10,000 workers) were reported. These cases included MSDs. The U.S. Department of Labor defines an MSD as an injury or disorder of the muscles, nerves, tendons, joints, cartilage, and spinal discs. MSDs do not include disorders caused by slips, trips, falls, motor vehicle accidents, or similar accidents.
BLS publishes detailed characteristics for MSD cases that resulted in at least one lost day from work. For example, the number of MSD cases and incidence rates are reported by sex, age, occupation, industry, and several other characteristics.
|MSD Cases with days away from work|
|Year||Total Cases||Incidence Rate||Median Days||Relative Standard Error|
(1) Incidence rates represent the number of injuries and illnesses per 10,000 full-time workers and were calculated as: (N / EH) X 20,000,000 where,
N = number of injuries and illnesses
EH = total hours worked by all employees during the calendar year
20,000,000 = base for 10,000 full-time equivalent workers (working 40 hours per week, 50 weeks per year)
Days-away-from-work cases include those that resulted in days away from work, some of which also included job transfer or restriction.
(3) Musculoskeletal disorders (MSDs) include cases where the nature of the injury or illness is pinched nerve; herniated disc; meniscus tear; sprains, strains, tears; hernia (traumatic and nontraumatic); pain, swelling, and numbness; carpal or tarsal tunnel syndrome; Raynaud's syndrome or phenomenon; musculoskeletal system and connective tissue diseases and disorders, and when the event or exposure leading to the injury or illness is overexertion and bodily reaction, unspecified; overexertion involving outside sources; repetitive motion involving microtasks; other and multiple exertions or bodily reactions; and rubbed, abraded, or jarred by vibration.
