Ergonomic Hazards
The goal of ergonomics (the science of matching work to the worker) is to reduce stress and eliminate injuries and disorders associated with the overuse of soft tissues, e.g., muscles or tendons, awkward posture, and repeated tasks.
Ergonomic risk factors are found in jobs requiring repetitive, forceful, or prolonged exertions of the hands; frequent or heavy lifting, pushing, pulling, or carrying of heavy objects; and prolonged awkward postures. Vibration and cold may intensify these conditions.
Your work activities and job conditions while working within confined spaces may include:
- Repetitive motion throughout your workday - cleaning procedures within the space can result in weakness and soft tissue damage over time.
- Working in awkward or stationary postures - work in piping and small enclosures forces awkward postures can cause fatigue and weakness.
- Lifting, lowering, pushing, and pulling heavy or awkward items - lifting, lowering, and moving heavy equipment into confined spaces can cause strains and sprains, and tear muscles, tendons, and ligaments.
- Using excessive force to perform tasks - turning large bolts, opening and closing heavy doors can result in torn muscles, ligaments, and tendons.
- Being exposed to excessive vibration - using heavy tools that vibrate can cause soft tissue damage and long-term injury.
- Extreme temperatures - confined space can be very hot or cold. Extreme heat, the most common temperature extreme in confined spaces, can quickly cause fatigue, heat exhaustion and heat stroke.
