Maintaining a safe environment for employees working on computers
Under health and safety law, you must ensure that the working environment meets certain minimum requirements
Workstation furniture The work desk or work surface should be big enough to allow the user to arrange the screen, keyboard and documents, etc. in a flexible way. It should be stable and positioned so that it's comfortable when an employee uses a document holder, but also big enough to let the user work comfortably and to alter their position.
The working environment You need to assess noise levels. The equipment shouldn't be so noisy that it distracts the user. If you can't use quieter equipment, consider soundproofing or moving the equipment. You could use partitions between noisy equipment and the rest of the workstation as an alternative.
Lighting is also an important consideration. Surrounding windows must have curtains or blinds which users can adjust to prevent reflected glare. If needed, provide users with lighting appropriate to their tasks and particular workstation. Users should have control over their lighting to prevent reflected glare.
Temperature-wise, the equipment should not give out so much heat that the user becomes uncomfortable, so monitor this. It's also important that you maintain ventilation, and you control humidity so that it is at a level which keeps the user comfortable.
Task design and rest breaks Good design of the task can be as important as the right choice of furniture and equipment. Whenever possible you should design jobs so that employees have a mix of activities and some control over which tasks they perform and when. You should match staffing levels to workload so that individuals are neither overworked nor underworked and give employees some say in the way work is carried out and the planning that goes into it.
An employee's need for rest breaks will vary depending on the type of work they are doing and how intensely they are working. As a general rule, however, short, frequent breaks are better than longer, less frequent ones. A 5–10-minute break after 50–60 minutes' work is better than a 15–20-minute break after two hours. The employee should, at times, have a choice over when to take breaks and they should be encouraged to do non-work activities during their break, ideally away from the workstation.
