Ergonomic chairs are a type of equipment utilized for safety reasons.
The term "ergonomics" is from a combination of two Greek words, "ergon" (work) and "nomoi" (natural laws). Ergonomics typically takes into account the type of work done, the work tools and the workplace environment, with an aim of identifying how workers can do the best possible job in their work environments. There are many types of ergonomic equipment and tools that help make workers safe, comfortable and less prone to work injuries.
Significance
Ergonomists study and research ergonomics, and they work to define many different types of ergonomic principles that help companies prevent worker injuries. These types of prevention methods include defining work postures that minimize unnecessary static work; incorporating healthy and safe postures; using the largest muscle groups possible when muscular force must be exerted; and performing work tasks from the joints at the mid-point of their ranges of motion. One way to facilitate this type of worker safety initiative is by giving employees and workers ergonomic equipment to use in their daily positions.
Chairs and Seating
Ergonomic chairs are types of safety equipment that aim to prevent worker injuries inflicted by poor seated positions. These types of seating tools should ease the worker's movement and minimize the risks of tipping over. They need to support the worker's weight and provide adequate lumbar support for the back. Armrests must have adjustable height and width settings. The seat height must be adjustable as well to allow the worker to align himself with his desk items and still allow his feet to rest properly on the floor.
Typing and Keyboards
There are many specialty keyboards and wrist pads designed as safety tools. They usually have curved forms and are designed to fit the natural hand positions. Even if the employee uses a standard keyboard, its position should be adjusted to prevent carpal tunnel syndrome. This can be done easily using a keyboard wrist pad.
Hand Tools
Light industrial and construction workers need to use ergonomic safety equipment as well. If the worker is using power tools, he should wear special gloves or utilize handle coatings to prevent the vibrations from injuring his hands, wrists and arms. According to a guide by the Centers for Disease Control, non-powered hand tools can prevent musculoskeletal disorders. Examples of this type of equipment are screwdrivers, cutting tools and pliers.
Eye Tools
According to the American Optometric Association, 90 percent of job-related eyestrain and injuries could be prevented with ergonomic equipment and tools. For example, workers should wear properly designed, protective eye gear, such as safety glasses, goggles, helmets and face shields. Office workers should take 20-second breaks every 20 minutes when working on computers. They should also increase font sizes, adjust screen brightness and position their computer monitors to slightly below their eye levels.
