1Working with Display Screen Equipment Health and Safety UnitWorking with Display Screen Equipment
2Possible ill-health effects resulting from using Display Screen Equipment at work Visual discomfort (eye fatigue and headaches)Upper limb disordersAches and pains (back, shoulder, neck or wrist) Musculoskeletal disorders (MSDs)Stress (mental and physical)
3Hazardous working practices associated with Display Screen Equipment Working with a poor postureWorking for too long without a break or change of positionA poor working environmentPoor management of workload
4Avoiding health problems Ensure the workstation is set up correctlyAdopt a good posture and change position regularlyEnsure the work is organised properlyAsk for an eye test if you have problems with your visionReport aches and pains or ill-health
5Display 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".
6Display screen users“Users” are those who habitually use a display screen as a significant part of their work.High Risk UsersUse DSE all day every dayLow Risk UsersUse DSE for short periods, but not every dayNon-UsersUse DSE very occasionallyModerate Risk UsersUse DSE a few hours every dayScreen Shots: Microsoft Outlook
7Employers dutiesAnalyse 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.
8Employers dutiesAnalysing workstations is normally done in the form of a Risk Assessment using checklists and will include the assessment of:Environmental conditions.Chairs and desks.Display screen equipment including keyboard.User/computer interface.
9The risk of ill-health is related to how the workstation is used. To reduce the risk:Change posture regularlyBreak up display screen workManage the workloadOrganise the worktopMaintain a good working environment
10Supervisors’ and managers’ responsibilities Be aware of the University policy and rules for health and safetyEnsure users follow the safe systems of work and good practicePromptly follow up reports of problems or ill-healthReport problems they cannot deal withLead by example
11Assessments Should be Made or Reviewed When: A new person joins the teamA member of staff informs you they are experiencing problems with their workstationA member of staff informs you that they have a disabilityA member of staff lets you know that they are expecting a childBefore any new technology, equipment or software is introducedThere is an office move or redesign of the area, layout or lightingThere is a change in the type of work or amount of time that someone is using the equipment
12Self-AwarenessThe 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.
13Self-AwarenessThis means building up good habits for looking after yourself while you workRemember 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.
14Self-AwarenessIf you feel pain or discomfort, anywhere, in your wrists, arms, shoulders, neck, back or legs……STOP!This is an indication that your body is getting tiredRelax your muscles, stand up, move around
15The following suggestions may help to provide you with a more comfortable environment.
16When 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.
19Position YourselfThere 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.
20Position YourselfTo support your back, consider the following:Choose a chair that provides support for your lower back.Source: Healthy Computing Guide
21Position YourselfAdjust your work surface height and your chair to assume a comfortable and natural body posture.Source: Healthy Computing Guide
22Position YourselfIt 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
23Position YourselfThe 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
24Position 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
25Position Yourself Zone your workstation. Source: Healthy Computing Guide
26Position YourselfTo minimise reaching and to promote comfortable shoulder and arm posturesPlace 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.
35Position YourselfType 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
36Position YourselfUse the keyboard legs if they help you maintain a comfortable and straight wrist position.
37Position 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
38Position YourselfPosition the top of the screen near eye level.
41Position 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.
42Position YourselfAvoid 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.
44Go Lightly 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.
45Go LightlyConsider 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.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.
46Go LightlyType 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
47Go LightlyAvoid 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.Source: Healthy Computing Guide
48Go LightlyAdjust your chair so the seat does not press into the back of your knees.Source: Healthy Computing Guide
49Go LightlyAdjust your chair so the seat does not press into the back of your knees.Source: Healthy Computing Guide
51Take BreaksTaking 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.
52Take Breaks Vary your daily activities. Plan your work so that one activity isn't performed for extended periods of time.Source: Healthy Computing Guide
54Computer InterfaceLearn about software and hardware features by reading the information that came with your software programs and hardware products.Source: Healthy Computing Guide
55Computer InterfaceUse 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
56Computer InterfaceWork 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
58Laptop UsersPortable 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 breakSelect equipment that is lightweight and up to the taskAssess the risk of theft and violence
59PDA UsersThe hazards around using Personal Digital Assistants (PDA) are similar to using a laptop or mobile phone for text messaging which are:Theft with menacesHealth issues similar to other DSE equipment
60PDA UsersJust 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 menacesDo not use them in such a situation and if you are threatened hand it overIn vehicles keep the equipment out of sightKeep any inputting brief and intermittent and do not input while your back, head and neck are hunchedPDA’s do not damage your eyes, but prolonged peering at a small screen may cause eye fatigue
61Summary To reduce risks associated with DSE: 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.
