1 Performing An Ergonomics Review

2 Why should I perform an ergonomics review? What is the function of an ergonomics review? How do I apply the steps involved in an ergonomics review? Performing an Ergonomics Review

3 What and Why There is obvious risk in this job, but by performing an ergonomics review, you’ll be able to clearly identify all the risks (not just the ones in this picture). You’ll also be able to give detailed and dimensioned recommendations. Performing an Ergonomics Review

4 What is an Ergonomics Review?  Assessment of job tasks  Follows the risk management process Recognize Evaluate Control  Results in effective and efficient ergonomic improvements What and Why

5 How do I do it? Performing an Ergonomics Review

6 How do I do it? Performing an Ergonomics Review Medical Data Employee Survey EASY BRIEF

7 Using Passive Surveillance  Worker Reports/Interviews  Review OSHA 300 Injury and Illness Logs  Review Workers’ Compensation Claims  Plant Medical Records  Symptom Surveys

8 Using Active Surveillance  Observations of workers performing tasks  Still photos/videotaping of work postures, workstation layouts  Workstation measurements  Measuring tool handle sizes, weighing tools and parts, & measuring tool vibration and part dimensions

9 Using Active Surveillance  Determining characteristics of work surfaces (i.e., slip resistance, hardness, & surface edges  Performing task analyses (i.e., time study)  Measuring exposures to heat, cold, noise, & WBV  Biomechanical calculations (i.e., muscle force required to accomplish task)  Physiological measures (i.e., heart rate, oxygen consumption)  Questionnaires, subjective ratings of perceived exertion

10  Step 1 – Select a job to review  Step 2 – Gather data  Step 3 – Analyze data  Step 4 – Complete the job improvement process Steps Performing an Ergonomics Review

11 Step 1 - Select a Job to Review Examine medical data from the past Interview operators Visually assess the jobs in the plant

12 Step 2 - Gather Data Obtain job information Perform task analysis Videotape the job Take still photos Interview the operator Gather medical data Take workplace measurements

13 Step 2 - Gather Data Gather Job Information What type of information do you need? Job name Department Shift length Production standards Production mix Rotation schedule Total exposure time Task analysis Gather Job Information

14 Step 2 - Gather Data Perform Task Analysis What is task analysis? Dividing a job into its main components, for example: Pull material on table Cut material with knife Transfer cut material to molding machine Activate molding machine Return to work bench

15 Worksite Analysis Job Hazard Analysis  Workers  Equipment  Materials  Task/Processes  Environment

16 Step 2 - Gather Data Videotape Job Viewing angle Front View Side View Top View

17 Step 2 - Gather Data Viewing angle Field of view Videotape Job Wide Angle Close Up Side View Top View

18 Step 2 - Gather Data Viewing angle Field of view How much footage? Tape all aspects of the job Tape different working conditions 3 cycles of the job Never too much footage Videotape Job

19 Step 2 - Gather Data What tools will you need? Video camera Battery charger Charged batteries Blank videotape Videotape Job

20 Step 2 - Gather Data Take Pictures Lighting, angle, field of view Photo quality Number of photos to take »Two or three shots per angle (minimum) »Take photos of parts, tools, displays, PPE »Take as many photos as you can

21 Step 2 - Gather Data What tools will you need? »Digital camera (with blank disks or a memory stick) »Battery charger »Charged batteries Take Pictures

22 Step 2 - Gather Data Interview Operator

23 Step 2 - Gather Data Gather Medical Data

24 Step 2 - Gather Data Review OSHA 300 Logs

25 Step 2 - Gather Data Symptom Survey

26 Step 2 - Gather Data Symptom Survey

27 Step 2 - Gather Data Dimensions Weights Forces Measurements

28 Step 2 - Gather Data Dimensions (side view) Bench height Control locations Part stacking Seat height Product dimensions Measurements

29 Step 2 - Gather Data Dimensions (Top view) Reach distances Carry distances Part locations Sight distances Lift locations Measurements

30 Step 2 - Gather Data Weights Part / box weights Tool weights Measurements

31 Step 2 - Gather Data Grip forces Push/pull forces Control forces Measurements

32 Step 2 - Gather Data Measurements What tools will you need? Grip meter Pinch grip Push/pull meter Tape measure

33 Step 3 - Analyze the Data BRIEF and EASY Upper Body Assessment Methods Strain Index ACGIH’s Threshold Limit Value (TLV) and Hand Activity Level (HAL) ACGIH’s Hand/Arm Segmental Vibration Threshold Limit Values (TLVs) Rapid Upper Limb Assessment (RULA) Upper Extremity Cumulative Trauma Disorder Risk Factor Identification Checklist GM-UAW Risk Factor Checklist Washington State Appendix B

34 Step 3 - Analyze the Data BRIEF and EASY Low Back Assessment Methods NIOSH Revised Lifting Equation Liberty Mutual (Snook & Ciriello) Tables for Lift/Lower, Carrying and Push/Pull Tasks 3D Static Strength Prediction Program (3D SSPP) 2D Biomechanical Analysis ACGIH’s Lifting Threshold Lifting Values (TLVs) Energy Expenditure Models

35 Step 3 - Analyze the Data BRIEF and EASY Whole Body Assessment Methods Ovako Working Posture Analysis System (OWAS) Rapid Entire Body Assessment (REBA) ACGIH’s Whole Body Vibration Threshold Limit Values (TLVs)

36 Step 3 - Analyze the Data BRIEF and EASY

37 Step 4 - Brainstorm Controls Generate as many ideas as possible There are no bad ideas

38 Priority Matrix Step 5 - Prioritize Controls

39 Step 6 - Develop Action Plan

40 Step 7 - Document Success
