20. Picture Perfect • FEET flat on floor • KNEES bent at about a right angle • THIGHS roughly parallel to the floor with knees slightly higher than hips • HIPS bent at a right angle • BACK supported by the seat back

21. Picture Perfect • HEAD tilted slightly forward • SHOULDERS in a relaxed position • UPPER ARMS hanging loosely at the side • ELBOWS bent at roughly a right angle • FOREARMS parallel to the floor • WRISTS straight – not bent either vertically or horizontally • FINGERS cascading downward to a position just above the keyboard

36. What Do You Look For on the OSHA Log? • 3 years of logs • Determine sprain/strain injuries • Determine body part • Group by job description • Determine root cause

39. Questions To Ask Yourself • What percentage did you arrive at? • Do you know the cost? • What can you predict about the future? • How can you fix it

40. What are the Risk Factors ofMSDs?

41. Risk Factors

42. Risk Factors • Duration • Force • Repetition • Awkward Posture • Static Posture • Vibration • Temperature Extremes

43. Other Contributing Factors • Work/Rest Cycles • Job Energy Demands • Work Pace • Work Schedules

44. How do you minimize these? • Equipment design • Equipment retrofit • Administrative controls • Person

46. Common Body Injuries • Neck/Back • Shoulder • Elbow/Hands • Knees/Feet

47. Neck Pain • Tight feeling in the neck on movement • Discomfort/pain when turning head or lifting arm • Head feels heavy and hard to hold up • Headaches

49. Back Pain • Pain in lumbar area • Pain in one or both hips • Pain radiating into leg, calf, ankle, foot Following nerve placement • Pain may be accompanied with numbness and tingling • Weakness in dorsiflexion of the foot
