Quantitative Risk Assessment is a risk management tool which analyses the risk by a quantitative evaluation of the consequences and their likelihood in a chemical process industry. QRA is widely used in assessing the risk in Oil & Gas Installations especially refineries, tank farms, cross country pipelines, bottling plants, terminals etc.

• To identify the major worst-case scenarios of high risk in a facility handling flammable and toxic products and to assess the risk for neighbourhood facilities / risk to public.
• To suggest recommendations in order to reduce the risk and bring down to ALARP.

Fire and Explosion Risk Analysis is the process of identifying potential fire / explosion hazards / risks in the process and storage areas of the facility handling highly flammable materials and suggesting appropriate mitigative/preventive measures.

Identification of hazards and potential hazardous events; Carry out Consequence Analysis for the identified scenarios such as Jet Fires, Flash Fires, Pool Fires, Flammable Gas Dispersion, Toxic Gas Dispersion, Vapour Cloud Explosion (VCE), and Smoke and Gas Ingress;

Building Risk Assessment is a process of identifying hazards associated with explosion, fire and toxic release that may affect process plant buildings and managing the associated risks. It also introduces the API recommended practice 752 “Management of Hazards Associated with Location of Process Plant Buildings, its relationship with OSHA 29 CFR 1910.1 19 and the recommended analyses for identifying the above hazards.

      Objective:

The Major Objective of Building Risk Assessment is to identify major hazards to which the Buildings might be exposed, carry out consequence modelling and recommend appropriate prevention and mitigation measures for the building that are subject to unacceptable consequences.

It is a useful tool to assist analysis of process and non-process industries. The main focus of BowTie Study is towards Major Accident Events, in which the personnel need to understand how these may occur and the barriers and degradation controls deployed to prevent them. BowTie studies are carried out based on CCPS guidelines on BowTie Risk Management.

      Objectives:

To provide a systematic analysis of the barriers along threat and consequence pathways that can prevent or mitigate a Major Accident Event and provide a cumulative picture of risk through the visualization of the number and types of barriers and degradation controls and their conditions. To assist in the development and understanding of how unwanted events can occur.

As Low As Reasonably Practicable – It is a term used to describe a target level for reducing risk that would implement Risk Reducing Measures (RRM) unless the costs of risk reduction in time, trouble or money are grossly disproportionate to the benefit.
