DSE Assessor Training. Safety, Health and Wellbeing October 2007. Aims of session. Knowledge of health & safety regulations. Identification of hazards and risks associated with DSE use Knowledge on how to avoid future injury/health problems.
Safety, Health and Wellbeing
Imposes general duties and requires employers to carry out risk assessments, make arrangements to reduce risk, appoint competent people and arrange for appropriate information and training.
Health and Safety (Display Screen Equipment) Regulations
Provision and Use of Work Equipment Regulations
Workplace (Health, Safety and Welfare) Regulations
1 Identify hazards (e.g. continual DSE use for long periods at any one time, awkward postures, poor lighting, etc…)
2 Identify people at risk (users of DSE)
3 Evaluate risk
4 Additional control measures (identification of remedial action that will eliminate/ reduce the risk)
The way a workstation is organised can also cause ULD’s or make them worse.
Therefore problems can be avoided by good workplace and job design, and by the way the DSE and workstationis used. Your role is to help in this area.
An employee who habitually uses Display Screen Equipment as a significant part their normal work is a user. This is established by the first few questions on the self-assessment.
Users are defined as
normally using DSE continuously for an hour or more; AND
use DSE in this way more or less daily; AND
have to transfer information quickly to or from the DSE; AND
also need to apply high levels of attention and concentration; or
are highly dependent on DSE or have little choice about using it; or need special training or skills to use the DSE.

The following slides look at how we can ensure that operators are working ergonomically at their workstation, for their job.
Non-neutral neck positions are where the head is jetting forward, flexed downward, rotated left or right. This can be caused by: monitor being too far away; image is too small or unclear; visual problems of operator; or incorrect seating.
Non-neutral neck positions increase muscular tension, increases the fatigue rate of the neck muscles.Neutral Position
For most jobs, armrests are not essential. They can restrict arm movement, although for many jobs they can provide comfort. They should be set back from the front edge of the seat, or be adjustable to allow the chair to be drawn up close to the work surface. The height of armrests should not be too low or too high to cause discomfort.
Back support height and tilt adjustable to keep the natural curve of the spine and thus meet the needs of a range of users.

If you are sitting incorrectly at a DSE workstation for continuous periods of time, it can cause a lot of distress in a number of different parts of the body
Elbows should be close to the worker’s side and bent at 90 degrees or slightly greater (100º – 110º).
Non-neutral positions of the arms add additional stress to both the shoulder, arm and wrist muscles.Shoulders, Elbows & Wrists

Stresses and strain placed on the ankle is not supported correctly (ie foot rest too high). Also if not supported as all then you can get pain at the back of the knee.
No stress or strain placed on the ankle

Often this is achieved by having the top of the screen level with the user’s eyes
Using a mouse
Reading the screen
Laptops have been designed to be compact and easily transportable for use ‘on the go’. The small keypad and screen design forces you to adopt awkward postures when using it. Laptops are not designed for prolonged use.
The best thing to do, is not use laptops unless necessary (e.g. you require a laptop because you work in different locations).
If you use a laptop you must:
Ankle Flex and Stretch - Alternately flex your ankle (point your toes up) and extend (point your toes down). Repeat with the other leg.
Repeat the above exercise a few times.
