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.

This paper Scoping Your Industrial Project: Best Practices for Success Scoping your industrial project is more than a kickoff step—it’s the foundation for budget, schedule, and long-term success. From aligning stakeholders to pressure-testing assumptions, a dynamic scoping strategy helps prevent costly missteps, manage risks, and keep your project on track from concept to completion. Control System Migrations | Part 7 | Best Practices for Installation, Testing, & Commissioning The cutover phase is the defining moment of a control system migration, where planning meets execution. From thorough backups and pre-shutdown prep to mechanical completion and commissioning, every step must be precise. Skipping even small details can lead to costly setbacks, while disciplined execution ensures a smooth, successful transition.

Basic Process Control Systems (BPCS) are used to monitor and control processes to make certain that they continue in a safe state while giving the operator continuous process information. Both during the design and operating phases, it also informs operators to any irregularities in the process that demand their attention.

The PHA Recommendation Playbook | Part 2 | Untangling Technical Complexity Technical complexity is one of the most underestimated challenges in resolving PHA recommendations. What seems simple on paper often reveals layers of engineering coordination, system interdependencies, and feasibility hurdles, turning compliance into a multifaceted effort that requires planning, collaboration, and the right support. The PHA Recommendation Playbook | Part 1 | Managing Resource Constraints Resource constraints are a common challenge in resolving PHA recommendations. Part 1 of this blog series explores how limited teams and tight funds impact compliance and safety and offers practical strategies to help facilities plan ahead, prioritize effectively, and stay on track.

The concentration of a combustible material in air below which ignition will not occur. Mixtures below this limit are said to be "too lean". It is often referred to as the Lower Explosive Limit (LEL). Lower Flammability Limit (LFL) 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.
