Operating a computer or video display terminal (VDT), like any form of sustained physical or mental work, may lead to visual, muscular or mental fatigue. Rest pauses, as recommended by National Institute for Occupational Health and Safety (NIOSH), to alleviate or delay the onset of fatigue, are necessary. Jobs should be designed so that the operator can vary VDT tasks with non-VDT tasks. In addition, open and positive working relationships between and among the employees and supervisor can be factors in reducing muscle tension and musculoskeletal disorders.
Employees may contact EH&S for guidance, training or intervention. Some examples of ergonomic complaints include:
- Chair discomfort
- Poor VDT arrangement
- Small workstation size
- Harsh room lighting
