A condition during which the alarm rate is greater than the operator can effectively manage. An alarm flood is normally defined to begin when the alarm rate exceeds ten (10) alarms in a ten-minute period and ends when it returns as a reduced alarm rate. aeSolutions can supply expertise at all stages of alarm management including consulting, training, and facilitating rationalization teams, followed by full design and implementation services.

What Are Tomorrow's Leaders Learning From Us Today? A Lesson in Ethical Leadership Leaders face constant pressure to move fast and hit targets.

Whitepaper: The Courage to Intervene | Developing Ethical Leadership in the Next Generation of Process Safety Professionals As the process industries experience the “great shift change,” developing the next generation of leaders requires more than technical competence. It demands ethical courage and the ability to influence others to uphold process safety under pressure. This paper explores how ethical decision-making and leadership behaviors can be intentionally developed through structured case-based learning derived from real engineering failures.

The architecture or voting arrangment used in the field instrument or final control element of a safety instrumented system (SIS) to reach a certain safety integrity level (SIL). Voting logics include one-out-of-one (1oo1), 1oo2, 2oo2, 2oo3, etc. For example, a 2oo2 voting logic indicates there are two protective devices/instruments in a system and both devices (two-out-of-two) are needed to properly shut down the system or mitigate the hazard. 1oo2 indicates that only one of the devices would be required to properly prevent the situation from occurring.

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.

Facility siting studies are used to ascertain location based risks for a plant and ensure that occupied buildings are located at a safe distance from process units. A Facility Siting Analysis is intended to evaluate the potential hazards and consequences of uncontrolled releases of flammable and toxic substances; to assess their potential for injuring the occupants of fixed and temporary structures on or offsite; to identify existing safeguards; and to determine measures to reduce the risk posed by these potential events. aeSolutions has trained facilitators to execute the hazard recognition and risk reduction process and experienced modelers that apply the appropriate methodology in line with API 752/753 and industry best management practices for Facility Siting. We provide results that allow your site leadership team to allocate resources more effectively to minimize facility siting risks.
