The Fire and Gas philosophy drives the design basis of the entire gas detection system. The philosophy should provide general direction, intent, specific performance goals, and effective strategies on how to implement the gas detection system. It clearly specifies the chemicals of concern and the intended purposes, i.e., detection of toxic or combustible levels, voting requirements, alarm rationalization, and control actions. aeSolutions' Fire and Gas team can support gas detection systems from conceptual design through field installation. This includes developing a Fire and Gas philosophy, technology selection, ensuring an appropriately sized system, and fire and gas mapping using the Geographic coverage approach and/or Computational Fluid Dynamics (CFD) scenario-based modeling to determine gas detector placement.

Intrinsic Safety is an equipment design approach that reduces the available energy to a level where it is too low to cause ignition. This is done for equipment that will be placed in particularly hazardous areas for the purpose to keep all temperatures low and to prevent sparks that could cause fires or explosions.

A Quantitative Risk Assessment is a systematic approach to determining the likelihood and consequences of hazardous events and expressing the results quantitatively as risk to personnel, the site being studied, the overall environment, and/or a company. Risk is a function of consequence and likelihood and aeSolutions has the experience and tools to evaluate both for a QRA. A QRA is a specialized approach to assess high consequence LOPA scenarios with large risk gaps to close. Further "pencil-sharpening" in the QRA will verify the severity of the scenario through consequence modeling, as well as the frequency of the scenario through fault tree modelling. Often conservative assumptions made in LOPA are revealed in QRA, which makes the solution to gap closure more practical. QRA will handle conditional dependence among IPL(s) and the initiating cause(s). aeSolutions utilizes commercially available software tools, along with in-house expertise, to facilitate QRAs. For example we can use the PHAST and SAFETI software to model chemical releases in evaluating consequences of an incident. QRA can be a valuable decision support tool when evaluating complex hazard scenarios.

Specialty Chemical Site’s Increasingly Complicated Cutover When a project that began with standard safety system upgrades quickly expanded to a much broader scope of engineering with tight deadlines, aeSolutions responded with an experienced engineering workforce to deliver above-quality expectations while meeting key deadlines. Challenge The initial project scope included providing the client with instrumentation specifications and wiring and cutover plans to facilitate the cutover to a new system. Due to incomplete and outdated instrument lists, a significant and unexpected change in scope became required to include instrument specification services, which nearly doubled the time and manpower needed to reach the goal by the client’s deadline. Solution aeSolutions efficiently identified and conveyed the necessary adjustments to the project with clear and concise communication, enabling the client to swiftly make informed decisions, modify the scope, and adjust staffing accordingly. Our team quickly deployed resources to provide the following deliverables within the original schedule: • Instrument Specifications • Instrument Field Wiring • Cutover Mapping • Cutover Wiring In addition, aeSolutions designed custom cabinets for the cutover at the request of the client once it became apparent that the field loops would be doubled. During construction, aeSolutions assisted the client with locating and providing quality drawings for cutover installation and commissioning. Results Upon completion, the clients informed aeSolutions that the provided support was indispensable for a smooth start-up, and the subcontractors confirmed that aeSolutions specifically contributed to one of the most efficient cutovers they’ve ever commissioned. The client had large projects going on, and aeSolutions was able to save them costs by hitting their shutdown dates and not requiring additional shutdown time.

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.
