Ergonomics involves designing and arranging workspaces so people work efficiently and safely. Ergonomics is used to evaluate how you do your work to identify any risk factors that might lead to injury, and then to find the best solution to eliminate or manage the hazard. Your capabilities and limitations are taken into account to ensure tasks, equipment, information and your environment suit you.
What are ergonomic conditions?
Ergonomic conditions are disorders of the soft tissues, specifically of the muscles, nerves, tendons, ligaments, joints, cartilage, blood vessels, and spinal discs. If you experience pain or injury in your soft tissues, it might be caused by factors such as repetition, force, awkward postures, contact stress, or vibration and may develop over time. These types of injuries and pains are not caused by slips, trips, falls or motor vehicle collisions.
Perhaps the most prevalent injuries in an office setting are related to ergonomics. Because office workers spend the bulk of their day seated at a desk and working on a computer, they are prone to strains and other injuries related to posture and repetitive movement. Ergonomics hazards can be difficult to detect. “Most office conditions that can be described as hazardous from an ergonomics perspective would appear quite innocuous to the everyday observer,” said Marc Turina, principal consultant for ErgoSmart Consultants in McKees Rocks, PA.
The following are steps that should be taken in order to be ergonomically safe in the office.
Provide Adjustable Equipment
One size does not fit all in an office workstation. “Adjustability is the key,” Turina said. “Chairs, work surfaces, monitor stands, etc., should all be adjustable in order to accommodate the widest range of employees.” He recommended presenting a variety of options to employees. Although employers may be reluctant to pay for expensive ergonomic equipment, experts insist the equipment is a wise investment. “A good keyboard tray may retail around $300; a good chair may retail around $500 to $700,” said Sonia Paquette, professional ergonomist and doctor of occupational therapy. She points out that the cost of the health claims that stem from not having these devices is much higher. “Some of these hard claims cost many tens of thousands of dollars just of medical treatment, let alone cost of replacement, absenteeism, loss of work production, etc.”
Train Workers on How to Use Equipment
Providing adjustable furniture and equipment is only the first step in creating an ergonomically sound workstation. “A big issue that I have encountered a lot lately is employee inability to properly adjust their own office chairs,” Turina said. “Many times, employers can invest $500 in an excellent adjustable chair, but employees still experience a bad workstation fit.” The problem often is twofold: Workers do not know how to adjust their equipment, and they do not know the most ergonomically beneficial way to set up their workstation. Train workers on both the ideal setup and how to operate adjustable equipment accordingly.
Keep Your Feet on the Floor
One of the first questions Paquette asks workers is whether their feet touch the floor when seated at their desk. “It sounds like an incredibly simple question,” she said, “but very often workers have their keyboard tray on the desktop, so in order to reach it, they need to jack up their chair so high that their feet can barely touch the floor.” She added that unless an employee’s feet are on the floor, a chair will not be able to reduce pain and discomfort. She recommended options such as adjustable keyboard trays or rolling tables adjusted to the proper height to eliminate this problem. Although footrests are a “second-best option,” their small surface may impede some of the worker’s movement.
Provide Document Holders
Frequently typing from hard copy can lead to neck strain if a worker is forced to repeatedly look down to the desk and back to the computer screen. Turina recommends providing document holders to reduce this strain. “These document holders are reasonably priced, and eliminate excessive cervical motion and help to prevent muscle imbalances,” he said. Document holders also are good for the eyes, according to the St. Louis-based American Optometric Association. Keeping reference materials close to the monitor reduces the need for your eyes to change focus as you look from the document to the monitor.
Correct Mouse Placement
Paquette often sees workstations where the computer keyboard is on a tray, but the mouse remains on the desk. “That spells disaster for the neck and shoulder on the side of that mouse,” she said. She recommends that the mouse always be placed beside the keyboard.
