Risk analysis is a crucial process in the design and safe use of machines and equipment. It allows the identification of potential hazards associated with a machine or equipment and to take measures to minimize the risks to users.

The international standard EN ISO 13849-1 is the standard for machine safety control systems. This standard defines the requirements for the design, installation and commissioning of machine safety control systems. It states that the risk analysis must be performed before the design of the machine or equipment to determine the risks associated with its use.

How to perform it

Risk analysis can be performed by following the following steps:

  1. Definition of the perimeter: determine the activities, products or systems that will be analyzed.

  2. Identification of hazards: list all potential hazards associated with the activities, products or systems considered..

  3. Evaluation of the probability and severity of the hazards: evaluate the probability of each hazard identified and the severity of their potential consequences.

  4. Determination of control measures: implement measures to minimize the probability of hazards occurring and reduce the severity of their consequences.

  5. Evaluation of the effectiveness of control measures: evaluate the effectiveness of the control measures implemented and make changes if necessary.

  6. Documentation: record the results of the risk analysis and the control measures implemented for ease of management and regular updates.

In summary, risk analysis involves characterizing each potential risk using three variables: the severity of the risk, the frequency of risk occurrence, and the detectability of the risk. These variables are evaluated on a defined scale and multiplied together to give a score. This score can help determine the corrective actions needed to minimize the risk.

Even if a risk is not considered serious or frequent, it is important to take it into account in the risk analysis. In this case, measures such as mentioning the risk in the user manual can help protect users against potential injuries and damage.

It is important to take into account the standards applicable to each area during the risk analysis. For example, in the forestry sector, there are standards that define the requirements for the safety of the machines and equipment used..


In conclusion, risk analysis is a crucial process in ensuring the safety of users of machines and equipment. It is important to take into account the applicable standards and to characterize the potential risks in order to take the necessary measures to minimize the risks to users.
