The technology sector is known for being one of the safest work environments. There are no jobs involving obvious physical risk, no dangerous machinery, and no exposure to chemicals. And yet, computer-related fatigue is now an emerging occupational hazard recognized under Spanish law, with documented consequences for workers« physical and mental health. Ignoring it because »you can’t see it” is one of the most costly mistakes a company in the sector can make.
Occupational safety and health in the IT sector isn't just red tape—it's a direct driver of productivity, talent retention, and legal compliance. This article explains what those risks are, what the regulations say, and how to address them.
What is considered an occupational hazard in the field of computer science?
An occupational hazard is any working condition that may cause harm to a worker’s health, either immediately or in the long term. In the IT environment, these risks aren’t explosions or falls from heights—they’re prolonged exposure to computer screens, maintaining poor posture for hours on end, cognitive overload, or accumulated technostress.
Scientific evidence shows that prolonged exposure to computer screens can lead to eye strain, musculoskeletal disorders, a sedentary lifestyle, and mental overload, especially when the ergonomic conditions of the workstation are inadequate. These issues develop gradually, leading many workers to dismiss them as normal until they become a serious problem.
Occupational Safety and Health Regulations Applicable to the IT Sector
The primary legal reference is Royal Decree 488/1997, which establishes the minimum health and safety requirements for workers using equipment that includes display screens. This regulation requires companies to assess the risks associated with each workstation, ensure appropriate ergonomic conditions, and provide workers with the necessary information and training.
Why Does the Technology Sector Also Need Occupational Safety and Health (PRL)?
There is a widespread perception that occupational safety and health is only relevant to construction sites, factories, or warehouses. Nothing could be further from the truth. The digitization has increased mental load, defined as the interaction between the cognitive demands of work and the worker’s ability to respond to them. Factors such as hyperconnectivity, multitasking, time pressure, and information overload can lead to mental fatigue, stress, and a decreased ability to concentrate.
| Topic | ❌ The Myth | ✔ The Reality |
|---|---|---|
| IT Risk | «In computer science, there are no real occupational hazards.» | Eye strain, musculoskeletal disorders, and technostress are legally recognized risks in Spain. |
| Telework | «Workplace safety regulations don't apply at home.» | Law 10/2021 requires companies to ensure the same safety conditions for remote work as for in-office work. |
| Mental load | «Stress is a personal matter, not the company's responsibility» | Cognitive overload and work-related anxiety are psychosocial risks that the company is required to assess and prevent. |
| Screens | «Staring at a screen all day doesn't hurt you» | Prolonged exposure to PVD causes clinically documented computer vision syndrome, headaches, and eye strain. |
| Posture | «A standard office chair is enough.» | Royal Decree 488/1997 requires an adjustable chair with lumbar support, armrests, and five legs. Each workstation must be evaluated individually. |
| Medical Examination | «It is only mandatory for high-risk jobs.» | Users of computer monitors are entitled to specific medical examinations of their eyes and musculoskeletal system. |
Major Occupational Hazards in the IT Field
Eye Strain
One of the most common effects of working with computer screens is eye strain, also known as computer vision syndrome. It includes dry eyes, itching, blurred vision, headaches, and a feeling of heaviness in the eyes. It can be prevented by adjusting the distance from the screen (between 45 and 55 cm), adjusting the brightness, and taking breaks every hour.
Muscle fatigue
Maintaining the same posture for hours on end causes tension in the neck, shoulders, wrists, and lower back. The key is an ergonomically configured workstation: an adjustable chair with lumbar support, a keyboard and mouse at elbow height, and a monitor positioned slightly below eye level.
Falls from a height or collisions with objects
Although less common, tech office environments also experience accidents caused by poorly managed cables, wet floors, or poorly arranged furniture. These are preventable risks that can be addressed with basic spatial organization.
Electrical contact
The intensive use of electrical equipment, especially in environments with servers or technical facilities, poses a risk of electrical shock. Periodic inspections of installations and compliance with electrical safety standards are mandatory.
Mental load
Symptoms include eye strain, headaches, difficulty concentrating, apathy, and the feeling of never being able to disconnect, and many people dismiss these as normal because they associate them with periods of heavy workloads. When left untreated, this can lead to operational errors, incidents, and sick leave due to anxiety or depression.
Factors within the organization
The organizational design of work is a risk factor in and of itself. Telework can lead to the emergence of psychosocial risks such as technostress, mental and computer-related fatigue, the risk of social isolation, the inability to disconnect from work, or a tendency toward self-exploitation. A policy of genuine digital disconnection and a reasonable workload are preventive measures just as important as physical ergonomics.
Frequently Asked Questions About Occupational Hazards in the IT Field
What are the most common occupational hazards in the IT field?
The most common are eye strain, musculoskeletal disorders caused by poor posture, mental overload, and technostress. In remote work environments, social isolation and difficulty disconnecting are added to the list.
Does remote work also require occupational safety and health measures?
Yes. Law 10/2021 on remote work requires companies to ensure the same health and safety conditions for remote workers as for on-site workers, including an ergonomic assessment of the workstation at home.
What does the law say about computer monitors?
Royal Decree 488/1997 stipulates that software must be tailored to the task at hand, be user-friendly, and display information in a format and at a pace suited to the operators. It also requires that workstations be evaluated and that specific medical examinations be provided to workers who use computer monitors.
Is work-related anxiety considered an occupational hazard?
Yes. Mental strain, anxiety, and depression stemming from the work environment are recognized as occupational hazards under Spanish law, and companies are required to assess them and include them in their prevention plan.
