Definition

Ergonomics refers to the study of people’s efficiency in their working environment. It aims to improve workspaces and tools to better fit the user and their tasks, thus enhancing their comfort, performance, and safety. Ergonomic principles are often used when designing workplace settings, including computer workstations, to ensure that tools and tasks are appropriately adapted to human physical and cognitive abilities.

Examples

  1. Computer Workstations: Adjusting monitor height to eye level, keeping keyboard and mouse at a proper height to allow for straight wrists, and using chairs that support the natural curve of the spine.
  2. Factory Machines: Installing controls at a height that reduces unnecessary physical strain and fatigue for operators.
  3. Office Setups: Using footrests to maintain proper leg positioning and reducing the risk of circulatory issues for desk-bound employees.

Frequently Asked Questions (FAQs)

What are the primary goals of ergonomics?

The primary goals of ergonomics are to improve safety, efficiency, comfort, and performance in the workplace. It aims to minimize the risk of harm or injury and maximize productivity by designing products and work environments that fit the user’s needs.

How can poor ergonomics affect health?

Poor ergonomics can lead to various health problems, such as musculoskeletal disorders (MSDs), carpal tunnel syndrome, chronic back pain, and repetitive strain injuries (RSIs). Long-term exposure to poorly designed workspaces can also lead to reduced productivity and increased absenteeism.

What is ergonomically designed office furniture?

Ergonomically designed office furniture supports proper posture and reduces physical strain. Examples include adjustable chairs with lumbar support, desks that can be set to appropriate heights, and accessories like keyboard trays and monitor stands.

What role do ergonomics play in workplace safety?

Ergonomics play a critical role in workplace safety by designing tasks, workspaces, controls, displays, tools, lighting, and equipment to fit employees’ physical capabilities and limitations. This reduces the risk of injury and enhances overall safety.

  • Human Factors: The study of how humans interact with systems and products, often synonymous with ergonomics.
  • Occupational Health: A field focused on health and safety in the workplace, which includes the study and application of ergonomics.
  • Workplace Safety: Policies and practices in place to protect employees from health and safety risks, including ergonomic practices.
