Construction work requires working in high, low, and tight spaces which often forces you to work in an awkward or uncomfortable position. Working in awkward reaching and bent positions can lead to shoulder and back discomfort and possible injury over time. Workers need to be aware of their range of reach and how to prevent injury. The diagram below illustrates the reaching zones when lifting or working. Each zone is categorized by a color based on your body’s ability to lift/work in each area.
The Green Zone shows the ideal location for working with your hands. When possible, try to keep your work tasks no farther than your wrists.
The Yellow/Orange Zone is for occasional work since it involves more weight on your shoulders and low back since your hands are away from your body. If needed, keep the reach distance as far as your fingertips.
The Red Zone is away from your body so far that it places you at higher risk for falls when in the air and shoulder and back discomfort. Limit the time you work reaching beyond your fingertips.
