1. ASEP Ergonomic support development Fall 2002 The Need... “Scientific evidence shows that musculoskeletal disorders of the lower back and upper extremities can be attributed to particular jobs and working conditions – including heavy lifting, repetitive and forceful motions, and stressful work environments…but the problem can be reduced with well-designed intervention programs.” National Academy of Sciences Report (1/18/2001) FY 99: 43% of all disabling workplace injuries and illnesses (nation-wide) are associated with ergonomics and at a financial cost of $16.8 billion. [Liberty Mutual Workplace Safety Index Report – 2002] FY 02: 62% LBNL DOE-Recordable cases caused by poor ergonomics (Strains/Sprains, CTDs & RSIs). FY 02: LBNL Property Management dBase inventoried > 9,400 computers (desktops and laptops) issued to employees. 7/99-8/02: 20% LBNL employee visits (168) to Health Services triggered by computer use. 4/85-6/02: 145 WComp “ergo claims” resulting > $2M incurred costs and 13,602 days of TD/Loss Work Days (productivity).
