Today we will talk about occupational risk assessment and try to explain in simple terms what it is, what methodology is followed to carry it out, and what benefits it brings.
Occupational risk assessment (ORA) is a key process for ensuring the safety and health of workers in any organization, ranging from ergonomic risks to safety in work at height. This process, regulated in Spain by Law 31/1995 on Occupational Risk Prevention (LPRL), establishes employers’ obligation to protect their workers against any risk arising from work activity, including the proper application of business activity coordination (CAE) for work at height when several companies share the same workplace.
Below, we explore what an occupational risk assessment is, how it is carried out, and how important it is for detecting risks and preventing accidents.
What Is an Occupational Risk Assessment?
Occupational risk assessment is the procedure by which the risks present in the work environment are identified and evaluated. According to the LPRL, an occupational risk is defined as the possibility that a worker will suffer harm arising from work. This harm can include illnesses, pathologies, or injuries related to work activity, ranging from exposure to chemical agents to situations of particular danger such as the work-at-height procedure.
The ORA process is not only about identifying risks, but also about analyzing their magnitude and determining the preventive measures needed to control or eliminate them. This procedure is essential so that employers can make well-founded decisions that help improve working conditions and ensure employee safety.
How Is an Occupational Risk Assessment Carried Out?
The ORA is a systematic process divided into several stages, each of which plays a crucial role in identifying and managing occupational risks. According to the guidelines of the National Institute for Safety and Health at Work (INSST), the assessment process consists of the following phases:
1. Determining the Risks Associated with Job Positions
At this stage, all the risks present in the different job positions within the organization are identified. This includes physical, chemical, biological, ergonomic, and psychosocial risks. Identification is based on direct observation of the work environment, consultation with workers, and review of past incidents.
2. Priority Analysis of Regulations, Standards, and Reference Documents
Once the risks have been identified, the regulations and standards applicable to each type of risk are analyzed. This ensures that the assessment is carried out in line with current legal and technical standards. Reference documents that may provide additional guidance on how to handle the identified risks are also reviewed.
3. Risk Characterization
In this phase, a detailed evaluation of each identified risk is performed. There are two main methods for risk characterization:
- Direct professional judgment (DPJ): Uses the experience and judgment of accredited professionals to evaluate risks.
- Methods requiring measurement, analysis, or testing (MAT): Involve more precise, quantitative techniques, such as environmental measurements or laboratory analysis.
4. Risk Evaluation
Here, the magnitude of each risk is estimated and preventive actions are prioritized according to their severity and likelihood of occurrence. This step is crucial for deciding which risks require immediate attention and which can be managed over the long term.
5. Planning, Implementing, and Verifying Preventive Measures
Finally, the preventive measures needed to control the identified risks are planned, implemented, and verified. This includes allocating resources, training workers, and installing protective equipment. In addition, ongoing monitoring must be carried out to ensure the effectiveness of the measures adopted and to make adjustments when necessary.

Why Is Occupational Risk Assessment So Important?
Occupational risk assessment is essential for several reasons:
- Accident and Illness Prevention
The main goal of the ORA is to keep workers from being harmed. By identifying and controlling risks, the chances of workplace accidents and illnesses are reduced, creating a safer work environment.
- Legal Compliance
Carrying out the ORA is a legal requirement in many countries, including Spain. Meeting this obligation not only avoids penalties but also demonstrates the organization’s commitment to the safety and health of its employees.
- Improved Productivity
A safe, healthy work environment improves employee morale and productivity. Workers who feel safe are more likely to be engaged and productive.
- Cost Reduction
Preventing workplace accidents and illnesses reduces the costs associated with sick leave, compensation, and staff replacement. Investing in the ORA is an effective way to minimize these expenses over the long term.
- Promoting a Safety Culture
Carrying out the ORA regularly fosters a safety culture within the organization. Workers become more aware of the risks and of the importance of following preventive measures, which contributes to a safer work environment.
Conclusion
Occupational risk assessment is an essential component of occupational health and safety management. This process is not only a legal obligation but also a vital tool for protecting employees, improving working conditions, and ensuring the sustainability and success of organizations.
By carrying out an ORA effectively, companies can detect and mitigate risks, prevent accidents and illnesses, and promote a safety culture that benefits everyone.
