Slide 2 Safe Lifting And Back Injury Prevention Member Name October, 2009 Slide 3 1 What You Need to Know About Safe Lifting & Back Injury Prevention in Less Than 30 Minutes Slide 4 2 Training Objectives Scope of Back Injury Problem Risk Factors the whole story Ergonomics Simple body mechanics principles for safe lifting Stretching and Warm-up Slide 5 3 Problem is Huge ..not to mention painful 80 % of population will experience severe back pain 25-40% of injury frequency 40- 60% of workers compensation costs Billion and billions of $$ Causation is complex and multi-faceted #1 Cause and Cost of Injury for FSRM Members Slide 6 4 Job Risk Factors Weight of the object lifted, pushed, pulled Location of person in relation to lift Frequency and Duration Rest and recovery periods Load stability and shape Workplace layout and equipment Training Environmental factors How work is organized Available lift assists Slide 7 5 Personal Risk Factors Age - strength/endurance decrease Body shape - tall vs.. short Stress/distractions on and off the job Lifestyle - habits, hobbies, health, diet Gender - differences Impact load on back e.g. jumping off tailgate, ramp, truck cab and lift truck Lifting techniques utilized Slide 8 6 The Living Machine Most work habits develop at an age when our bodies are virtually indestructible (or so we sometimes believe)! Slide 9 7 Sleeping Driving Work Child Care House Work Watching ESPN It is not just about how you use your body while working, but all day long! Typical 24 Hours The Living Machine - Slide 10 8 Pain is a great motivator What can you do? Ergonomics Body Mechanics (Choices) Stretching & Warm-up Slide 11 9 Ergonomics Ergonomics is about fitting jobs to the people who work them. The goal of ergonomics is to: Reduce Injuries Get More Done with Less Effort Get it Done Right the First Time Slide 12 10 Applying Ergonomics Think about ways to reduce the risks associated with: Repetition High Force Awkward Postures Distance Vibration, Heat, Cold Slide 13 11 Lifts: Which load is heavier? 20 lbs. LEAD 20 lbs. h Slide 14 12 In order to hold a 20-lb weight at about 8 inches from your spine, you must exert a counteracting force of 80 lbs. Lifts Slide 15 13 When lifting loads in work situations, you often need to extend your arms and slightly bend forward. The body center of gravity shifts forward and some of the weight of your upper body must also be taken into account. For example, in order to support a 20-lb weight at 20 inches from the spine while leading forward, the counteracting force must be equal roughly to 400 lbs. Lifts F1 F2 Slide 16 14 What is obvious from this picture? Force Distance F x D = ? Key Point Slide 17 15 For every action there is When muscles contract to cause movement there is an opposite muscles that counters that motion to keep the body in balance. Not all muscles react at the same speed. Key: Avoid fast, jerky, motions move smoothly. Slide 18 16 If you remember anything, remember... 1. Force x Distance!!! Reduce the distance To the center of gravity of object Get close to the load, hug it Turn object up on shortest dimension Avoid above shoulder lift Avoid below knee Maintain neutral posture Avoid twisting, move your feet Reduce the force Know your lift limits; test load Get help Use mechanical assist devices Lift slowly (Force = MA, Newtons Laws) 2. Slow your motions 3. Drink more water!!! 4. Breathe while lifting, dont hold breath! Slide 19 17 Pay Attention to How You Use Your Body......Because it is paying attention to how you use it!...Because it is paying attention to how you use it! Slide 20 18 Everyone has some inclination for ergonomics. Slide 21 19 Body Mechanics, its not about right or wrong... its about better! its about better! Slide 22 20 Body Mechanics Principles Keep it Close! Power Positions! Staggered Stance! Feet First? Build A Bridge! Prepare and Compensate! Slide 23 21 Keep it Close! Slide 24 22 The Power Positions Arms Legs Back Lifts performed between waist and chest level promotes effective use of these muscles. Slide 25 23 Staggered Stance Wide base of support Feet apart Diagonal Foot position Normal Stance Lifting Stance Slide 26 24 440 lbs Feet First Lead with your feet Not with your head 549 lbs Slide 27 25 Build a Bridge Avoid standing or lifting while bent forward If you must, then build a bridge For one-handed activities or lifts Place the other hand on a steady object or your own knee to take your own body weight out of the lift For two-handed activities or lifts Stagger your stance placing one foot forward of the other to place support under your body weight Be aware of invisible lifts (head, body, twists) Eliminate the weight of the upper body from the lift Slide 28 26 Prepare and Compensate: When Standing! Get a foot up Bend knees Staggered stance Where else do you commonly see foot rails? Slide 29 27 Your head weighs 10-12 pounds. Head forward posture puts up to three times more force on the base of your neck. Headaches are associated with this posture. Prepare and Compensate: Watch your Head! Slide 30 28 Prepare and Compensation: Pull and Push Pushing is easier! Slide 31 29 In most industries how do you determine if a lift is a one person or two person lift? Prepare and Compensation: Get help when needed! Slide 32 30 You let one person lift it... and if he gets hurt, its a two person lift! Slide 33 31 See It Think It Do It Keep it Close Power Positions Staggered Stance Build a Bridge Prepare and Compensate Lifting Principles Slide 34 32 On What Date Did You Lose Your Flexibility? It did not happen on a specific date. You lost it gradually over time. Be patient. It will take time to regain it. Slide 35 33 Prepare and Compensate Stretching and Warm-up Why do animals stretch? Why do athletes stretch? Why dont most people stretch? Slide 36 34 Why Do Animals Stretch? Their bodies says stretch and they stretch. Your body says stretch and you have a debate. Slide 37 35 Why Do Athletes Stretch? Enhances safety. To warm muscles and increase ease of movement Stretching decreases muscle fatigue after the game Enhances performance. To increase blood flow to working muscles Slide 38 36 Why Dont Most People Stretch? Not accepted behavior I look silly or not cool Environment not conducive no time Does not always feel good in beginning. Previous injuries Slide 39 37 Why Does Stretching Help? It allows your body to breathe! When muscles fatigue they need oxygen. Stretching provides it! Increase blood flow which improves oxygen exchanges Increased blood flow promotes healing Slide 40 38 Warming-up and Stretching Warm-up Warm muscle is easier to stretch than cold muscle Warming allows your muscle to take full advantage of your existing flexibility Stretching Opens pathway for blood & oxygen Helps muscle recover from activity Speeds up removal of toxins from working muscle Slide 41 39 Back Safety is about choices Ergonomics Body Mechanics Stretching What do you choose?
