BakerRisk uses the most recent version of ISA’s performance-based fire and gas technical report (ISA TR84.00.07-2018) as a starting point for developing optimal coverage.  Our proprietary Fire and Gas Tool software (F&GTool©) leverages our well-established facility siting study (FSS) and quantitative risk assessment (QRA) methodologies to perform the complex calculations required to efficiently determine the optimal placement of fire and gas detectors.

We use a two-step approach to calculate unit coverage at a client site:
  • 1 A high-level qualitative approach is used by experienced professionals to define detector locations based on results from a consequence model.
  • 2 The consequence based detector placement can be optimized using a more detailed, risk-based quantitative approach. This method takes into account the likelihood of failure, ignition environments, occupancy, congestion/confinement, and other risk-based considerations to optimize the number and placement of detectors. A QRA is recommended before performing this analysis.

BakerRisk also performs studies to assess the coverage of existing detector systems and identify potential gaps.  For detector locations within buildings, we perform detailed CFD analyses to help with fire and gas detector placement in closed structures.

Through our comprehensive analysis, BakerRisk offers our clients the confidence that potential releases of hazardous materials will be detected.

Utilizing the extensive industry and operations experience of our staff combined with BakerRisk’s proprietary software tools for calculating hazard consequences (SafeSite3G©), risk (QRATool©), and detector location and coverage (F&GTool©), a defensible approach can be applied for fire, flammable gas, toxic gas, and acoustic detection mapping.

We have the expertise to efficiently assist with the following:
  • Detector placement locations
  • Overall detector coverage (consequence and risk based)
  • Detector placement optimization
  • Unit-specific detector system recommendations
  • Validation of coverage for currently-installed detector systems
  • Risk reduction calculations where F&G systems are credited in LOPA or similar analyses

Changes in Facility Siting Standards: API 752, 753, & 756

September 27, 2023

In industries where the daily risks of potentially catastrophic events, such as vapor cloud explosions, are a constant concern, there’s no room for compromise – inherently safer design principles, effective hazard identifications and analyses, and adherence to up-to-date industry standards aren’t just important, they’re essential. Since its establishment in 1919, the American Petroleum Institute (API)…
