Don’t overlook contributing factors to ergonomic hazards
There are many ways to analyze ergonomic hazards and identify contributing factors. Some methods are relatively simple, and others require detailed analysis and sophisticated equipment. A simple approach might involve using checklists. A more comprehensive strategy breaks each job down into specific movements like reaching and grasping.
Job analysis methods also vary according to the type of work they address. Some focus on job area design, while others are specific to work types, like materials handling. Still, others focus on the work environment, like lighting and temperature extremes.
Whatever method you use, identifying potential problems is essential to coming up with improvements. Identifying contributing factors can be done in three simple steps:
- Look for clues. Try to identify jobs that may be causing problems by looking around the jobsite, talking to workers, and looking for early warning signs.
- Prioritize the tasks in each job. Ask workers how complex the task is and how often they perform the task. This allows you to compare different tasks and prioritize those with the highest risk — address jobs with higher risk scores before looking at tasks with lower scores.
- Observe the work. Each job task may have contributing factors, and injuries occur from a combination of factors in multiple tasks. Also, talking to workers who perform the work can provide valuable information about improving the job.
This three-step system above is inexpensive and straightforward. Different approaches address specific jobs, tasks, or work areas. If problems seem complicated or widespread, you may need to contact an ergonomics consultant or other expert.
