The highest concentration of a vapor or gas that will produce a flash of fire when an ignition source is present. At concentrations higher than the UFL, the mixture is too rich to burn. It is often referred to as the Upper Explosive Limit (UEL). Upper Flammability Limit (UFL) concentrations are considered for endpoint distances 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.

Pharma Company Detecting Natural Gas Leaks in Boiler House A pharmaceutical client determined they needed a natural gas leak detection and isolation system for a utility building based on a PHA recommendation. aeSolutions installed a combustible gas leak detection system to shut off the gas supply to the boiler, bringing the facility into compliance with the safety program requirements. Challenge A global pharmaceutical company’s corporate standards mandated a local manufacturing site install a combustible gas leak detection system in its boiler house to mitigate risk to personnel and equipment. The client needed the ability to detect and isolate gas leaks within a utility building containing multiple large natural gas-fired boilers to lessen the risk to personnel and reduce the potential for extended production disruption due to significant equipment damage. Solution aeSolutions designed and provided an FM approved industrial fire alarm and gas detection system to automatically isolate the main natural gas feed to the building when a leak is detected. aeSolutions also provided detector placement consulting services based on the physical location of potential leak sources. Delivered: • FGS 1300 fire alarm and gas detection/isolation system • Automatic isolation valve installed in natural gas supply line • Eight point gas detectors • Detector placement services Results The client now has an industrial grade system for detecting and isolating a release of natural gas, reducing the risk to personnel and equipment, and complying with their corporate safety program requirements. Learn more about how aeSolutions could help you with a similar gas detection project.

Improve performance with advanced alarming techniques from aeSolutions. Reduce nuisance alarms and enhance control system effectiveness. Advanced Alarming Techniques Service Click Here to Chat With Our Advanced Alarming Techniques Experts Enhancing Alarm Performance Through Context-Aware and Dynamic Strategies aeSolutions provides advanced alarming techniques capabilities to help facilities move beyond basic alarm configuration and implement more intelligent, context-driven alarm strategies. By leveraging advanced methods, facilities can reduce nuisance alarms, improve operator awareness, and ensure alarms are meaningful and actionable under varying process conditions. Traditional alarm approaches often treat alarms as static, regardless of operating mode or process state. This can lead to excessive alarm activity, especially during startups, shutdowns, or abnormal situations. aeSolutions helps clients implement advanced alarming strategies that adapt to real-time conditions, improving signal-to-noise ratio and enabling operators to focus on what matters most. Advanced Alarming Across Leading Control System Platforms Our team implements advanced alarming strategies within the native capabilities of major DCS and SCADA platforms, including Emerson DeltaV, Honeywell Experion, Honeywell TDC, ABB 800xA, Yokogawa CENTUM VP, Rockwell PlantPAx, Siemens PCS 7, and Schneider Electric Foxboro. As an independent consultancy, we help you maximize the value of your existing control system infrastructure without requiring additional software purchases. Where Advanced Alarming Delivers the Most Value Advanced methods are most effective in specific, well-defined situations: units with frequent mode changes (startup, shutdown, batch transitions) where static alarms cause predictable floods; compressor or rotating equipment sequences where alarm states depend on machine status; processes with multiple operating modes where normal alarm limits differ significantly between modes; and areas with chronic alarm flooding that persists after rationalization because the root cause is context, not configuration. Advanced alarming is not appropriate everywhere. We help clients identify where these methods are justified, design the strategies within an approved alarm philosophy, validate behavior before deployment, and train operators on the new alarm behaviors. Advancing Alarm Performance Beyond Traditional Approaches Our published research identifies state-based alarming for startup and shutdown conditions and dynamic alarm suppression during known process transitions as the next phase of advancement for facilities that have completed structured rationalization. These advanced methods build on, rather than replace, the foundational alarm management work that produces measurable results. The result is reduced operator fatigue during process upsets, fewer unnecessary alarm activations during transitions, and operators who trust that every alarm they see requires action. By applying these strategies effectively, facilities can strengthen alarm performance and take a meaningful step toward moving from risk to resilience. Our Advanced Alarming Techniques services include: Implementation of state-based alarming to adjust alarm behavior based on operating conditions Design and configuration of alarm shelving and suppression strategies Application of dynamic setpoints and alarm limits based on defined operating states, approved engineering calculations, or validated process models Identification and reduction of nuisance and chattering alarms Integration of advanced alarming strategies within existing control systems Alignment with ANSI/ISA-18.2, EEMUA 191, or IEC 62682 lifecycle and alarm management best practices Support for testing, validation, and operator training on advanced alarm behaviors Performance monitoring and continuous improvement recommendations aeSolutions works closely with your operations, engineering, and control system teams to implement advanced alarming strategies that are practical, resilient, and tailored to your facility. Whether enhancing an existing alarm management program or addressing persistent alarm challenges, our expertise helps deliver clearer, more effective alarms that support better decision-making and safer operations. — DON'T JUST TAKE OUR WORD FOR IT — Evidence-Backed Results — Trusted By Industry Leaders — Ag Chem Battery Materials & Mineral Processing Chemical Manufacturing Energy & Power Generation Hydrogen Production & Processing Metals & Mining Processing Oil & Gas Production & Processing Petrochemicals & Hydrocarbon Processing Pharmaceutical & Life Sciences Manufacturing Renewable Fuels & Bioenergy Specialty Chemicals & Advanced Materials Utilities & Critical Infrastructure Ag Chem Battery Materials & Mineral Processing Chemical Manufacturing Energy & Power Generation Hydrogen Production & Processing Metals & Mining Processing Oil & Gas Production & Processing Petrochemicals & Hydrocarbon Processing Pharmaceutical & Life Sciences Manufacturing Renewable Fuels & Bioenergy Specialty Chemicals & Advanced Materials Utilities & Critical Infrastructure Ag Chem Battery Materials & Mineral Processing Chemical Manufacturing Energy & Power Generation Hydrogen Production & Processing Metals & Mining Processing Oil & Gas Production & Processing Petrochemicals & Hydrocarbon Processing Pharmaceutical & Life Sciences Manufacturing Renewable Fuels & Bioenergy Specialty Chemicals & Advanced Materials Utilities & Critical Infrastructure Learn More About aeSolutions — Let's Discuss Your Advanced Alarming Techniques Needs —
