MODULE: INTRODUCTION TO ERGONOMICS |
STEP 7: Proactive ergonomics
Initially ergonomic changes will be reactive responses to problems as they occur; however the ultimate goal should be a proactive approach that seeks to prevent problems, enabling early detection and more timely interventions in potential ergonomic problems. Ergonomic issues should be identified and resolved in the planning stage of the process. Design strategies should emphasize fitting the job demands to the capabilities of the employees.
See the document Ergonomic (MSI) Risk Factor Identification and Assessment Tool for example of assessment, and
Job Hazard Analysis Tools for evaluating job risk factors.
