Industrial facilities use multiple safeguards to prevent hazardous process conditions from escalating into serious incidents. Where instrumented protection is required, a Safety Instrumented System (SIS) can automatically move the process toward a safe state when predefined conditions are detected. But how reliable does that protection need to be? A SIL
Identify potential hazards early, prioritize significant risks, and support safer engineering and project decisions before risks become more difficult to manage. Aura Safety & Risk Consultants provides Preliminary Hazard Analysis (PHA) for industrial facilities and projects as part of its process safety services. The study provides an early, structured view
Process industries routinely handle hazardous chemicals, pressure, temperature, stored energy and complex operating conditions. A failure in equipment, controls, procedures or human interaction can develop into a serious process safety incident. Process Hazard Analysis (PHA) provides a structured way to identify these hazards, understand credible accident scenarios and evaluate whether
Green hydrogen is becoming an important part of the transition toward lower-carbon industrial and energy systems. It is generally produced by using electricity from renewable sources to split water through electrolysis, creating hydrogen and oxygen. From a sustainability perspective, this creates significant opportunities. From a process safety perspective, however, hydrogen
Liquefied Natural Gas (LNG) facilities involve cryogenic conditions, flammable hydrocarbons, complex process equipment, storage systems and transfer operations. A deviation in pressure, temperature, flow, level or operating sequence can create conditions that require careful evaluation before they develop into a significant process safety event. A Hazard and Operability Study (HAZOP)
A HAZOP study captures the hazards and operability concerns identified using the process information and operating assumptions available at the time of the study. But an operating plant rarely remains unchanged for years. Equipment is replaced. Production rates change. Control systems are modified. New chemicals may be introduced. Operating procedures
A HAZOP study guide does not normally examine an entire process plant as one large system. The process is divided into smaller, manageable sections called HAZOP nodes, and each node is systematically reviewed for deviations from its intended operation. Selecting those nodes correctly is an important part of preparing an
A Hazard and Operability Study (HAZOP) is a structured method used to examine how a process can deviate from its intended design or operating conditions. One of the most important parts of this methodology is the systematic use of HAZOP guidewords and process parameters. Guidewords such as No, More, Less,
A Hazard and Operability Study (HAZOP) is intended to systematically examine a process or operation, identify credible deviations from design intent, evaluate their potential causes and consequences, and review the safeguards available to control the associated risks. But completing a HAZOP does not automatically mean every important hazard has been
Industrial facilities depend on two closely connected systems: the process that produces, handles, stores, or transfers materials and the electrical infrastructure that keeps equipment and critical systems operating. Hazards can develop in either area. A process deviation may result in abnormal pressure, temperature, flow, or level. An electrical deviation can
A substation failure rarely affects only one piece of electrical equipment. A fault, incorrect protection setting, switching error, equipment malfunction, or failure of a critical safeguard can propagate through the electrical network—potentially causing equipment trips, loss of power, production interruption, or dangerous conditions for personnel. This is why electrical safety
Safeguard High-Hazard Energy Projects with Specialist QRA Studies As LNG, hydrogen, and green energy infrastructure continues to expand, facilities face unique process safety challenges that conventional hydrocarbon risk models cannot fully address. Cryogenic temperatures, high-pressure systems, hydrogen flammability, and emerging energy technologies require specialized risk assessment methodologies. Aura Safety provides
