Consequence and Risk Analysis

Facility Siting Studies

BakerRisk has performed a multitude of facility siting studies on over a thousand process units worldwide for over 20 years. Our experience gained through incident investigations, research and blast testing programs results in continuous improvements to techniques and software tools used in our project activities throughout the world.

BakerRisk participated in the development of API 752 and 753 and uses these recommended practices to assist with facility siting studies and QRA’s to meet client corporate guidelines. If a company does not have internal guidelines, BakerRisk can assist with the development of robust methodologies that can be applied consistently across their assets to meet the intent of industry and company guidelines for facility siting and QRA’s.


SafeSite3G® allows you to predict the consequences throughout your entire facility from explosions, fire, and toxic releases, whether accidental or from a terrorist threat.

Determining potential consequences posed by facility operations is a necessary step in the process of developing a comprehensive safety plan. A facility siting study assesses potential explosion, flammable, and toxic consequences. Facility siting study results identify hazard vulnerabilities to aid with identification of potential mitigation strategies.

Hazards can lead to severe consequences if not managed properly

Examples of mitigation strategies to be considered include occupancy reduction, upgrading a building’s blast resistance, building relocation to areas less susceptible to damage, installing flammable or toxic gas detection with automatic or manual ventilation shutdown, providing personnel protective equipment, etc.

BakerRisk engineers have performed facility siting studies at a wide range of facilities around the world, including refineries, terminals, gas plants, LNG and LPG operations, pipeline systems, offshore platforms, floating production storage and offloading (FPSO) facilities, oil and gas wells, and chemical, petrochemical, and pharmaceutical plants.

BakerRisk can assist with building structural upgrades as a means of
mitigating blast vulnerabilities identified in facility siting studies

BakerRisk documents each facility siting study in a report that defines inputs, explains calculation methods, provides interim calculation results to allow verification and validation of the methods employed, and summarizes results in a range of meaningful forms. Composite contour plots of overpressure, flammability, and toxicity define key endpoints and provide an overview of areas vulnerable to impacts from assessed hazards.

Example overpressure contour plot

BakerRisk typically summarizes facility siting study results in an extensive spreadsheet table showing the maximum impact for each release size category for each building assessed. Blast impacts are presented in terms of building damage level (BDL), and flammable and/or toxic impacts are shown in terms of concentration categories predicted to reach each building.


Hazardous Release Consequence and Building Damage Assessment Tool

SafeSite3G® allows for the prediction of consequences throughout a facility from explosions, fires, and toxic releases.

The facility data and information can be easily managed through a self-contained database and be quickly accessible so as to query the consequences at a given building from a postulated hazard.

Using the state-of-the-art Baker-Strehlow-Tang methodology, SafeSite3G® allows you to quickly perform screening studies using pre-defined building types, predicting the blast produced by a vapor cloud passing through multiple zones of congestion.
