Possible ill-health effects resulting from using Display Screen Equipment at work V isual discomfort (eye fatigue and headaches) U pper limb disorders A ches and pains (back, shoulder, neck or wrist) Musculoskeletal disorders (MSDs) S tress (mental and physical)
Hazardous working practices associated with Display Screen Equipment Working with a poor posture W orking for too long without a break or change of position A poor working environment P oor management of workload
Avoiding health problems Ensure the workstation is set up correctly A dopt a good posture and change position regularly E nsure the work is organised properly A sk for an eye test if you have problems with your vision R eport aches and pains or ill-health
Display Screen Equipment Regulations 1992 The Regulations relate to the protection of employees who habitually use display screen equipment as a significant part of their normal work. Regulation 1(2) c defines such employees as "Users".
Display screen users Users are those who habitually use a display screen as a significant part of their work. High Risk Users Use DSE all day every day Moderate Risk Users Use DSE a few hours every day Low Risk Users Use DSE for short periods, but not every day Non-Users Use DSE very occasionally Screen Shots: Microsoft Outlook
Employers duties Analyse workstations of employees covered by the Regulations and reduce the risks. Ensure workstations meet minimum requirements. Plan work so there are breaks or changes of activity. Provide eyesight testing and any necessary correction for VDU work. Provide health and safety training. Provide information.
Employers duties –Environmental conditions. –Chairs and desks. –Display screen equipment including keyboard. –User/computer interface. Analysing workstations is normally done in the form of a Risk Assessment using checklists and will include the assessment of:
The risk of ill-health is related to how the workstation is used. Change posture regularly Break up display screen work Manage the workload Organise the worktop Maintain a good working environment To reduce the risk:
Supervisors and managers responsibilities Be aware of the University policy and rules for health and safety Ensure users follow the safe systems of work and good practice Promptly follow up reports of problems or ill-health Report problems they cannot deal with Lead by example
Assessments Should be Made or Reviewed When: A new person joins the team A member of staff informs you they are experiencing problems with their workstation A member of staff informs you that they have a disability A member of staff lets you know that they are expecting a child Before any new technology, equipment or software is introduced There is an office move or redesign of the area, layout or lighting There is a change in the type of work or amount of time that someone is using the equipment
Self-Awareness The nature of your job means that you are bound to experience a certain amount of pressure. This in itself is not a problem. However, when you are working hard, because of peaks in workload and tight deadlines, it is essential to manage the cause of any stress you are experiencing.
Self-Awareness This means building up good habits for looking after yourself while you work Remember that, no matter how correct your posture is, sitting for long periods in the same position will eventually lead to muscle fatigue. Be aware of the need for relaxation. Writing for prolonged, concentrated periods can lead to mental fatigue and tiredness.
Self-Awareness This is an indication that your body is getting tired Relax your muscles, stand up, move around If you feel pain or discomfort, anywhere, in your wrists, arms, shoulders, neck, back or legs…… STOP!
The following suggestions may help to provide you with a more comfortable environment.
When working at the computer adapt your surroundings and arrange your computing equipment to promote a comfortable and relaxed body posture. Because everyone has a unique body size and work environment, we can't tell you exactly how to set up your workstation to avoid discomfort.
There is a natural forward curve of the spine in the neck and lower back regions (the cervical and the lumbar regions). These natural curves are maintained when you sit up straight with your shoulders back. Correct seat adjustment will help you with this.
Position Yourself Choose a chair that provides support for your lower back. To support your back, consider the following: Source: Healthy Computing Guide
Position Yourself Adjust your work surface height and your chair to assume a comfortable and natural body posture. Source: Healthy Computing Guide
Position Yourself It is important that the chair has both an adjustable backrest and seat. They act together to ensure a comfortable, ergonomic posture. Source: Healthy Computing Guide
Position Yourself The optimum seat height is the distance from the back of your knee to the floor when your feet are flat on the ground. Source: Healthy Computing Guide
Position Yourself To promote comfortable leg postures Clear away items from beneath your desk to allow comfortable leg positions and movement. Use a footrest if your feet do not rest comfortably on the floor. Source: Healthy Computing Guide
Position Yourself Zone your workstation. Source: Healthy Computing Guide
Position Yourself To minimise reaching and to promote comfortable shoulder and arm postures Place your keyboard and mouse or trackball at the same height; these should be at about elbow level. When typing, centre your keyboard in front of you with your mouse or trackball located close to it.
Place frequently used items comfortably within arm's reach.
Place reference documents just within reach.
Position Yourself To promote proper wrist and finger postures. Keep your wrists straight while typing and while using a mouse or trackball. Avoid bending your wrists up, down, or to the sides.
Type with your hands and wrists floating above the keyboard, so that you can use your whole arm to reach for distant keys instead of stretching your fingers. Source: Healthy Computing Guide
Position Yourself Use the keyboard legs if they help you maintain a comfortable and straight wrist position.
Position Yourself To minimise neck bending and twisting. Centre your monitor in front of you. Consider placing your documents directly in front of you and the monitor slightly to the side, if you refer to your documents more frequently than your monitor. Consider using a document holder to position your documents near eye level. Source: Healthy Computing Guide
Position Yourself Position the top of the screen near eye level.

Position Yourself To minimise eyestrain. Place your monitor at a distance of about arm's length when seated comfortably in front of the monitor. Remember to clean your screen; if you wear glasses, clean them, also. Adjust your monitor brightness, contrast, and font size to levels that are comfortable for you.
Position Yourself Avoid glare. Place your monitor away from light sources that produce glare, or use window blinds to control light levels. Reflective glare can cause you to deviate from your natural posture in order to see the screen clearly.
Physical forces continuously interact with our bodies. We may only think of high-impact forces, such as car crashes, as injuring our bodies. However, low forces may also result in injuries, discomfort, and fatigue if they are repeated or experienced over long periods of time.
Go Lightly Contact force, or pressure that occurs when you rest on an edge or hard surface. For example, resting your wrists on the edge of your desk. Consider the following types of low forces: Dynamic force, or a force that you exert through movement. For example, pressing the keys while typing or clicking the mouse buttons. Static force, or a force that you maintain for a period of time. For example, holding your mouse or cradling the phone.
Go Lightly Type with a light touch, keeping your hands and fingers relaxed, as it takes little effort to activate keyboard keys. Also, use a light touch when clicking a mouse button or when using a joystick or other gaming controller. Source: Healthy Computing Guide
Go Lightly Avoid resting your palms or wrists on any type of surface while typing. The palm rest, if provided, should only be used during breaks from typing. Relax your arms and hands when you're not typing. Don't rest on edges, such as the edge of your desk. Hold the mouse with a relaxed hand. Do not grip the mouse tightly.

Go Lightly Adjust your chair so the seat does not press into the back of your knees. Source: Healthy Computing Guide

Taking breaks can go a long way in helping your body recover from any activity and may help you avoid MSDs. The length and frequency of breaks that are right for you depend on the type of work you are doing. Stopping the activity and relaxing is one way to take a break, but there are other ways, also. For instance, just changing tasks-perhaps from sitting while typing to standing while talking on the phone-can help some muscles relax while others remain productive.
Take Breaks Vary your daily activities. Plan your work so that one activity isn't performed for extended periods of time. Source: Healthy Computing Guide
Learn about software and hardware features by reading the information that came with your software programs and hardware products. Source: Healthy Computing Guide
Computer Interface Use different input devices, such as your mouse and keyboard, to accomplish the same task. For example, to perform a scrolling task, you can use the wheel on the mouse or the arrow keys on the keyboard. Source: Healthy Computing Guide
Computer Interface Work more efficiently by using software and hardware features to reduce your effort and increase your productivity. For example, you can press the Windows logo key to open the Start menu. Source: Healthy Computing Guide
Laptop Users Portable equipment is designed for short term use because they are not adjustable. You can use them, but to reduce the risks keep their use brief and double your efforts to give muscles a break Select equipment that is lightweight and up to the task Assess the risk of theft and violence
PDA Users The hazards around using Personal Digital Assistants (PDA) are similar to using a laptop or mobile phone for text messaging which are: Theft with menaces Health issues similar to other DSE equipment
PDA Users Just as using a mobile phone may make you a target for attack you should be aware of using the equipment where its use may inspire theft with menaces Do not use them in such a situation and if you are threatened hand it over In vehicles keep the equipment out of sight Keep any inputting brief and intermittent and do not input while your back, head and neck are hunched PDAs do not damage your eyes, but prolonged peering at a small screen may cause eye fatigue
Summary The workstation must be set up correctly. The equipment must be used properly. The work must be suitably organised. Users, supervisors and managers should be aware of the possible health risks. Users, supervisors and managers should follow procedures and work safely. Users should report any problems to their supervisors or managers. To reduce risks associated with DSE:
