Site Management and Logistical Support

Following an incident, effective site control, scene documentation, and evidence collection and preservation are critical aspects of any investigation. BakerRisk’s team of seasoned investigators excel at managing various considerations to swiftly establish a functional site management plan. Through collaboration with clients, government agencies, and stakeholders, we work to ensure the preservation, thorough documentation, and proper retention of evidence, aligning with industry-accepted practices while accommodating diverse environmental, safety, and regulatory parameters.

site management activities include:

  • Securing the incident scene to preserve scene conditions and protect items of evidentiary value from degradation or alteration by unauthorized personnel
  • Development of protocols to ensure involved parties are able to conduct their investigations in a safe and efficient manner
  • Site activity coordination with facility personnel and involved parties
  • Evidence management including collection, preservation, and examinations.
  • Protocol preparation for coordinating laboratory inspections, testing, and analyses
  • Evidence management throughout the life cycle of the investigation

Scene Documentation and Evidence Collection

Our knowledge of relevant incident investigation guidance documents and extensive real-world experience gained from hundreds of incident investigations have allowed us to provide robust and streamlined scene documentation and evidence collection services. Our investigators assist in identifying evidence and prioritizing the collection of time-sensitive items, and you can trust our team of investigators to execute these activities in strict accordance with industry best practices. We meticulously document the scene, collaborate with relevant parties to establish evidence collection and in-situ testing protocols, and rigorously conduct evidence testing and collection, adhering to both site-specific and industry-wide requirements.

Scene documentation and evidence collection activities include:

  • Site documentation, including multimedia (still image, videography, drone video), debris mapping, and heat mapping
  • Damage indicator documentation and measurement
  • Photo documentation, mapping, tagging, and collection of evidence
  • GPS mapping of site characteristics and items of evidentiary value
  • Protocol development for the identification, removal, preservation, and examination of evidentiary items
  • Evidence custodian support, including evidence logs, chain of custody transfers, visitor logs, sample splitting, etc.
  • Facilitating evidence examination and testing protocols at the scene or in a laboratory

Cause Analysis

From the outset, we have been dedicated to assisting clients in effectively determining incident causes. Whether it involves fires, explosions, or industrial chemical incidents, the core objective remains the same: identifying root causes to develop safeguards against recurrence. Drawing on extensive industry experience spanning residential and commercial building fires, offshore platform incidents, and catastrophic equipment failures, along with the use of advanced analysis software like our proprietary CATree© tool, BakerRisk excels in examining incident scenes, crafting hypotheses for causes, and offering valuable insights for future mitigation strategies.

Cause determination activities include:

  • Conduct witness interviews
  • Review electronic data, such as security camera footage, process information, automatic alarms, etc.
  • Analysis and review of process status and changes using physical or electronic evidence and witness statements
  • Timeline of event development
  • Identification of potential ignition, fuel, and oxidant sources
  • Mapping and analysis of fire patterns
  • Fuel dispersion, ignition, combustion, and other fire dynamics modeling
  • Damage indicator characterization and explosion simulation
  • Structural response modeling
  • Development of logic, event, and other cause analysis diagrams

Incident Reconstruction

We have the capabilities necessary to evaluate specific aspects of a hypothesized scenario, depending on the complexity of the reconstruction effort. With in-house expertise that includes the development and execution of engineering calculations, numerical modeling simulations, and exploratory test implementation, our team leverages both computer and experimental models to reconstruct various aspects of an incident.

Contact us today

Reconstruction tests and computer simulation activities include:

  • Evaluation of gas-fired industrial oven burner systems
  • Analysis of natural gas dispersion and mixing inside of a purpose-built structure
  • Recreation of industrial pneumatic tool failures
  • Modeling air infiltration into inerted storage tanks
  • Scale modeling of coal mine ventilation patterns
  • Replication of runaway chemical reactions
  • Application of computational fluid dynamics (CFD) modeling to simulate flammable releases on offshore platforms
  • Finite element analysis (FEA) modeling of blast wave effects on a storage tank
  • FEA modeling of piping system failure effects on a large furnace

Expert Witness Litigation Support

Our proprietary root cause analysis tool.

CATree© is a state-of-the-art Root Cause Analysis (RCA) tool that requires less training and is more comprehensive than other similar techniques. This user-friendly tool provides a systematic, consistent, repeatable process designed to help users identify potential root causes. What makes CATree© unique is its ability to cover not only the regulated elements of process safety and occupational safety health and environment (SHE) but also the additional elements in risk-based process safety (RBPS), including:

  • Safety culture
  • Tools and equipment
  • The life cycle of engineering projects (both capital and smaller management-of-change)
  • Human factors

Our proprietary CATree© provides a reliable method for understanding the underlying root causes behind incidents, enabling the implementation of corrective actions that directly address these core issues.
