This paper examines risk assessment for display screen equipment (DSE) work environments, outlining the legal and practical obligations employers have to protect employee health and well-being. It identifies key risk factors such as duration of equipment use, accuracy demands, and common health conditions including upper limb disorders, eyestrain, and stress. The paper further explores ergonomic requirements for furniture, lighting, and workspace layout, and discusses how risk assessments must be tailored to employees with special needs, including physical disabilities, dyslexia, and weight-related accommodations. The paper concludes that thorough DSE risk assessments benefit both employees and employers by reducing illness, accidents, and associated costs.
Display screen equipment refers to screens that display information such as text, numbers, or graphics. Risk assessment for a display screen work environment therefore focuses on the variety of hazards that workers may face in relation to such equipment. An employer is obliged by law to protect the health and well-being of his or her employees. Beyond legal compliance, the safety and well-being of employees also contribute to job satisfaction and higher rates of employee retention. A risk assessment is therefore an important step in this process.
Certain risk factors should be taken into account as part of a risk assessment for this environment. These include the length of time during which the equipment is used in a single sitting. An hour or more per day, for example, may carry significantly greater risks than sessions of 45 minutes or less. The requirement for high accuracy in tasks where errors carry serious consequences also creates elevated risk in terms of employee stress levels.
A risk assessment should also address the health problems commonly associated with display screen equipment. These include upper limb disorder, which may refer to pain in the neck, arms, elbows, wrists, hands, and fingers. Excessive use of a mouse encourages reliance on only one side of the body and may therefore increase risk for that side. Temporary eyestrain and headaches, fatigue, and stress are further health risk factors associated with DSE use.
A risk assessment should include evaluations not only of the employee's time spent working with the equipment, but also of other factors such as the ergonomics of furniture, equipment, and the work environment in general. The specific job requirements of each individual vary and should be taken into account when assessing risk for that particular employee.
Minimum requirements to mitigate risks should be incorporated into the risk assessment. These should be determined in terms of ergonomics related to chairs, display screen equipment, lighting, noise, reflection and glare, space and layout, and work surfaces. All of these elements should be arranged in a way that minimizes risk and discomfort to the employee, particularly for those who are required to spend long periods of time in front of a display screen.
"Tailoring DSE assessments for individual employee needs"
If an employee has only one arm, the positioning of equipment such as the mouse and keyboard must be considered. An employee with only a left arm, for example, would require the mouse to be placed on the left side of the keyboard. Additional time should also be allowed for this person to complete typing and other similar tasks.
A person with dyslexia may also need extra time to complete work if the task involves a large amount of reading and comprehension. Assigning such a person to high-accuracy tasks would likely be a mistake and would create elevated risk factors for the organization. Nevertheless, such an employee can be given less demanding tasks within the display screen environment, or assigned to areas that present less of a challenge, such as visual or non-reading tasks.
For an employee weighing in the range of 130 kg, special adjustments need to be made with regard to seating. The strength and durability of chairs must be taken into account, for example. The comfort level of such an employee is also important, and chair sizes will likely need to be adjusted so that the employee can sit comfortably in front of the display screen.
Risk assessments can help both to promote the health and well-being of employees and to save money by mitigating the likelihood of accidents and illness. A thorough and individualized approach to DSE risk assessment therefore serves the interests of both the employer and the workforce.
