Reducing Repetitive Tasks & Awkward Postures

Welcome back, let's Build Smart & Build Safe! We’ve covered safe lifting. Today, we’re focusing on the quiet killers of longevity in construction: repetitive tasks and sustained awkward postures.

These two factors lead to chronic pain and conditions like carpal tunnel syndrome, tendonitis, and joint damage. Ergonomics helps us modify the work itself to reduce this daily wear and tear.

1. Eliminating Repetitive Motion

Repetitive actions—like swinging a hammer, screwing in fasteners, or troweling—can inflame tendons and nerves over time.

• Mechanize it: If a task requires repetitive motion, look for a power tool solution. Using a power screwdriver instead of a manual one saves your wrist hundreds of twists per day.

• Rotate Tasks: If a highly repetitive job must be done manually, rotate workers every few hours. This allows one muscle group to rest while a different group is engaged, preventing localized strain and fatigue.

• Take Micro-Breaks: During repetitive work, take a 30-second stretch break every 10–15 minutes to allow muscles to relax and blood flow to return to normal.

2. Avoiding Awkward Postures

Sustained awkward postures, such as working overhead or kneeling for long periods, compress joints and restrict blood flow.

• Use Platforms, Not Ladders: For overhead work (above chest height), use scaffolding or adjustable work platforms instead of stretching or straining on a ladder. Keep the work between mid-chest and shoulder height whenever possible.

• Extend Your Reach: Use long-handled tools (brooms, mops, trowels) to avoid deep bending. For plumbing or electrical work, use rolling creepers or thick foam pads to prevent direct pressure on your knees.

• Adjust the Work: If possible, place your material or workbench on supports so the material is at waist height, allowing you to work with a straight back and neutral posture.

By consciously adjusting the way you work, you are investing in a longer, healthier career.

Tomorrow, we'll look at specialized hazards like tool vibration and cold weather.
