Safety study: HAZOP in combination with LOPA.

Companies with hazardous installations should identify the hazards and asses the risks of their installations and equipment. To this end, a company must periodically inventory and evaluate the risks when working with hazardous installations.

This risk identification (or hazard identification) can be carried out by means of a HAZOP study, whereby the risk assessment can be carried out, for example, using LOPA. Such safety studies should be periodically updated.

Hazard identification

There are several methods of performing a hazard identification. This includes:

  • HAZOP (Hazard and Operability Study)
  • What-If
  • SWIFT (Structured What-If Technique)
  • FMEA (Failure Mode Effect Analysis)

These methods all involve structured and systematic brainstorming techniques in which a multidisciplinary team tries to identify the dangers of a factory or installation.

Risk assesment

Risk assessment, risk analysis, risk management or risk evaluation concerns the quantification of risks, for example originating from a hazard identification (like HAZOP). Usually the potential consequences of a hazard are compared with the probability of occurrence: Risk = Probability x Consequence.

There are several methods for performing a risk assessment, for example:

Nowadays, the LOPA method is often used to assess risks. The combination of HAZOP and LOPA is a powerful tool for identifying the hazards of an installation and then controlling the risks.
