The vertical height is not easily adjustable which tends to inhibit employees from making necessary adjustments. Several studies have indicated that the ability to make slight alterations to seated postures is important in maintaining worker comfort and in relieving over exertion of muscle groups. The stools do not have swivel capacity which is useful in preventing employees from twisting their torsos while in a seated position. Twisting while lifting even light loads reduces the stability of the spine and increases the risk of low back injury. A fully adjustable ergonomic chair should be provided for the employee.
Employees have some extended and elevated reaches to access materials.
Rearranging the work space to move supply bins as close as possible should remediate this problem. Should be replaced with ergonomic seating. The one tool used is a pliers type device which has a handle which is too short. It should be replaced with a tool having a longer, flatter handle to relieve contact trauma to the palm of the hand. The overall height of the work top is a little low which forces the employee to severely tilt the head while performing the task and also requires slight deviation of the wrist while performing the fastening function.
