Occupational risk prevention system auditor


Occupational risk audits assess the effectiveness of occupational risk prevention systems applied by companies. The regulations on occupational risk prevention and auditing thereof are set forth in Law 31/1995, of 8 November, on occupational risk prevention, and Royal Decree 39/1997, of 31 January, which sets out the Regulations for prevention services. Similarly, the Regulations for prevention services provide that auditors cannot have any commercial or financial link, or any type of relationship other than that of an auditor, with the companies they audit, nor can they perform the role of an occupational risk prevention technician for these companies.


Occupational risk prevention system auditors assess the effectiveness of prevention systems, with a particular emphasis on whether the system complies with the current regulations on occupational risk prevention.

Auditors' primary tasks are defined in the Regulations on Prevention Services.
  • They check the methods used in the initial and subsequent periodic occupational risk assessments, analysing the results and verifying them where necessary.
    The occupational risk prevention regulations state the obligation to perform an initial assessment of occupational risks at companies. If this initial assessment identifies existing occupational risks, an occupational risk prevention plan must be implemented in order to reduce or eliminate them. For this reason, auditors check that an initial assessment has been performed and whether the results reflect the reality. Where there are any doubts, they analyse the risk assessment results. Where occupational risks have been identified, auditors check whether periodic assessments are being/have been carried out when there are changes at the company, in personnel/positions and in working conditions.
  • They check whether the type and planning of the preventive measures adhere to the general regulations.
    Auditors verify that the preventive measures have been organised in accordance with the company and the risks identified in the initial assessment, bearing in mind that the regulations specify how companies should organise their occupational risk prevention system. Where risks have been identified, the company is obliged to define and plan preventive measures to reduce or eliminate them. Auditors verify that the planning of the preventive measures suits the risks that have been identified and the characteristics of the company. They also verify that the preventive measures comply with the occupational risk prevention regulations that have been applied at the company.
  • Analyse the suitability of the procedures and means necessary to implement the preventive measures.
    Having completed the risk assessment and established the relevant preventive measures, auditors check whether the procedures determined to apply them (e.g. the procedure for investigating occupational accidents) are correct and comply with the regulations. They also determine whether the business has allocated suitable resources for the preventive measures, whether a specific and appropriate budget has been set aside for training the workers and whether the company's machinery complies with the regulations, etc.
  • They analyse the resources that the company has allocated to preventive action.
    They verify whether the human and material resources allocated by the company are suitable for applying the preventive action agreed upon on the basis of the results of the occupational risk assessment. For example, if a risk associated with exposure to a chemical product is identified, preventive action must be planned in order to reduce this risk and resources must be assigned to achieve this.
