Process Safety Analysis

HazOp, HAZID, PHA, FERA, QRA, LOPA analysis
Request a consultancy to identify risks in the use of complex systems or in entire production processes.

Discover the most suitable qualitative-quantitative analysis methods for process risks

The risks associated with complex systems or entire production processes are identified, estimated and analyzed based on the accidental or non-accidental changes of fundamental parameters of the main physical properties that characterize the process in question.

These are some of the process risk analysis methodologies that we can carry out to support your security area:

  • HazOp (Hazard and Operability), group analysis that takes place on the guideline of the IEC 61882 standard with the aim of identifying process changes that can cause safety problems
  • HAZID (Hazard Identification), study carried out starting from the design phases and related modifications, with the aim of identifying all the foreseeable risks associated with the process in use
  • PHA (Preliminary Hazard Analysis), analysis aimed at identifying, classifying and describing faults, their origin, possible consequences and related mitigation measures
  • FERA (Fire and Explosion Risk Analysis), an assessment of the risk of fire and explosion that provides for the calculation of the probability of fire and accidental explosion as well as the consequences
  • QRA (Quantitative Risk Assessment), analysis based on the estimation of the probability of occurrence and consequences of dangerous situations for people, the environment and the asset
  • LOPA (Layer of Protection Analysis), quantitative risk analysis according to the IEC 61511-2 standard for one or more accidental scenarios classified according to the severity of the consequences and the frequency of occurrence.

Through our consultancy you will be able to identify the risks by accessing tailor-made solutions using the most suitable technique for the type of process and security systems in question.


HazOp, or Hazard and Operability Analysis, is a risk analysis technique defined by the international IEC 61882 standard to assess workplaces and identify the dangers to which workers are exposed. In particular, the HazOp technique is conducted through a group analysis to identify how the production process can be diverted, which could generate accidents and compromise safety.

PHA, or Preliminary Hazard Analysis, is a system risk analysis technique based on analyzing the safety and reliability of the systems themselves and how they can be improved using appropriate measures for mitigation.

LOPA, or Layer of Protection Analysis, is an advanced technique for process safety analysis based on quantitative risk analysis according to the IEC 61511-2 standard, which classifies several causes of risk that are independent of each other based on the severity and frequency of the possible occurrences.
