A fire that spreads by means of a flame front rapidly through a diffuse fuel, such as a dust, gas, or the vapors of an ignitable liquid, without the production of damaging pressure. Flash fires produce relatively short term thermal hazards with negligible overpressure (blast wave) and burn through a pre-mixed vapor cloud largely horizontally as a vertical ""wall of flame"". Flash fires are considered during facility siting studies or consequence modeling conducted by aeSolutions' experienced modelers. Modeling helps companies identify the flammable and/or toxic consequences and impacts to receptors due to a chemical release.

A Strategic Integration of SIS, BMS, and PSM in a Boiler Fuel Conversion Project Implementing Safety Instrumented Systems (SIS) and Burner Management Systems (BMS) within tight deadlines and supply chain disruptions is challenging. A recent project converting boiler fuel from coal to natural gas with a Safety Instrumented BMS met strict safety standards despite these hurdles. Challenge The objective was to implement an SI-BMS using a Siemens PCS 7 Platform within a compressed schedule, meeting all Safety Lifecycle requirements. Traditionally, projects follow a sequential process, but due to time constraints, a concurrent development strategy was necessary. This included early procurement of long-lead items and expedited planning to ensure the BMS was built and commissioned during the scheduled plant outage. Solution • Concurrent development of PHA/LOPA and SIS deliverables • Early identification and procurement of long-lead items • Integrated planning with client and boiler equipment supplier • Close collaboration between SMEs in SIS and BMS • Rapid approval processes for drawings and system fabrication Results The project developed an integrated schedule to manage activities effectively, significantly reducing the risk of late changes. Collaboration between the client, the boiler equipment supplier, and SMEs in SIS and BMS maintained the fast-tracked schedule while meeting all Safety Lifecycle requirements. Effective planning and cooperation among stakeholders were key to achieving project objectives, offering valuable insights for future projects.

Periodic test performed to detect dangerous hidden failures in a system so that, if necessary, a repair can restore the system to an ""as good as new condition"", or as close as practical to this condition. The goal of a proof test of a SIF is to reveal previously undiagnosed dangerous hardware failures (those failures that would prevent the SIF from reacting to a hazard). Proof test coverage (the fraction of these failures a given proof can reveal) and the interval at which proof tests are conducted are important inputs into determining if a SIF meets its required SIL. Developing a proof test philosophy can provide for consistency in proof test procedures and how they are conducted. aeSolutions' experts have the field experience to discuss the testing requirements, site practices and available technologies to determine and document a comprehensive testing philosophy. We also have a library of proven proof test procedures to choose from when assembling a testing package, and we have the expertise to work with clients to implement effective testing, failure classification, and feedback mechanisms to validate reliability data claimed in Risk Analysis and SIL Verification.
