Hazard Study

The Hazard Study process has been developed by industry to review the hazards and risks of major projects in order to enhance their implementation. The use of the Hazard Study process ensures that hazards and identified and managed at an early stage of the project design. The value of the hazard study process, such as the established HAZOP study technique, is well recognized in the process industry.

Our consultants have experience in leading these studies for major projects including for new industrial sites. They also have experience in developing hazard study processes as part of corporate project risk management processes.


HAZID (HAZard Identification) study is a general concept studies aiming at identifying hazards. These studies follow a very similar format to HAZOPs, although a different set of guidewords are used.

HAZIDs are often conducted prior to the start of detailed design of a process, for example as input to a risk assessment required from a regulatory approvals point of view, and are typically used to identify major hazards likely to impinge on the process under review. Typical HAZID guidewords or phrases can include fire, explosion, release of toxics, environmental pollution etc.
