711 Introduction to Ergonomics

Engineering Controls

These controls are preferred over all others because they make permanent changes that can totally eliminate hazards at the source. Although they may be more expensive to implement than other controls, their effect is often more significant.

Let's look at some of the various engineering control strategies that may be effectively used to eliminate hazards.

Workstation Design

Some common ergonomic changes in workstation design include:

• Adjustable furniture: Chairs, desks, and other furniture that can be adjusted to fit the employee's height and body size can help reduce strain on the body and improve posture.
• Proper lighting: Adequate lighting can reduce eye strain and improve visibility, reducing the risk of accidents and improving productivity.
• Noise reduction: Reducing noise levels in the workplace can help reduce stress and improve concentration.
• Computer setup: Proper positioning of computer monitors, keyboards, and mice can help reduce eye strain, neck and shoulder pain, and carpal tunnel syndrome.
• Footrests: Footrests can help employees maintain proper posture and reduce pressure on the lower back.
• Document holders: Document holders can help reduce neck and eye strain by keeping reference materials at eye level.
• Wrist supports: Wrist supports can help reduce strain on the wrists and prevent carpal tunnel syndrome.
• Anti-fatigue mats: Anti-fatigue mats can help reduce foot and leg fatigue for employees who stand for long periods.
• Adequate storage: Adequate storage can help reduce clutter and keep work areas organized, reducing the risk of accidents and improving productivity.
