Ergonomics Basics
The study of fitting the job to the individual Match the design of tools, controls, and equipment to
fit the needs of the userPoor design and poor working practices can lead to
musculoskeletal disorders (MSDs) Ex: carpal tunnel syndrome, trigger finger, sciatica, etc.
Injuries are most likely to occur when people work in awkward postures or using repetitive motions for an extended amount of time

Minimize Risk Factors
• The most prominent ergonomics risks are:
• Forceful exertions• Repetitive motions• Awkward postures• Static postures• Cold temperatures• Compression/contact stress• Poor lighting• Vibration

Boost your Lab Ergo IQ
1. Start with proper attire. Shoes: cushioned sole, closed toes and heels, impervious material Loose-fitting clothing may interfere with work
2. Pay attention to posture. Keep feet flat (adjust height or use footrest) Keep your back straight

Boost your Lab Ergo IQ
4. Embrace the mini break to avoid fatigue. Plan short breaks into your day after 20 minutes at any task or
any time you are doing a repetitive task Quick mini breaks (2-3 minutes) or changing tasks
5. Reduce contact stressors Pad sharp edges or provide arm supports
6. Be mindful of work zones Arrange frequently used items to minimize reaching

Neutral & Awkward Posture
Neutral posture is a position that puts no stress on the body; positions that induce stress are awkward postures
Cumulative stress over time can lead to injury or musculoskeletal disorders.

Arm Strength = Neutral Posture

Typical laboratory bench height is ~ 94cm

Sitting
Desk cut-outs allow you to be closer to the work zoneKeep cut-outs free of clutter

Chairs
Chairs should be adjustable in order to fit a wide variety of employees
