Process Hazard Analysis (PHA) studies are vital to understanding and managing hazards at the job site. Effective PHAs enable informed decisions for improving process safety – this preserves lives, assets, and the environment. We provide experienced leadership, considered preparation, and attention to detail, fulfilling the requirements of an effective PHA and allowing you to focus on your operating facility.

Our dedicated service extends to PHAs big and small, across the United States including:

• Initial PHA
• Revalidation PHA
• Clean-Sheet PHA
• Management of Change (MOC) PHA/Request for Change (RFC) PHA
• Capital Project PHA (small, large, greenfield)
• Front-End Loading (FEL) PHA
• Detailed Design PHA
• Pre Startup Safety Review (PSSR) PHA

Protecting both plant assets and personnel are the cornerstones of all safety programs. ISC specializes in evaluating pressure relief systems (PRS) from both an equipment protection perspective and an associate safety perspective.

Equipment Protection

Freeing your process engineers to run your plant is the goal in any project. ISC assists in all aspects of the pressure-relief device validation and sizing process from gathering pertinent process safety information (PSI), developing all credible overpressure scenarios, and utilizing pressure relief software to get the most accurate validation/sizing calculations. We follow the American Petroleum Institute (API) Standards 520, 521 and 2000, as well as the customer’s standards and procedures.

Employee and Community Safety

Dispersion modeling is crucial to analyzing the consequences of potential releases from pressure safety valves (PSVs). Our engineers are experienced in modeling both overpressure and spurious failure scenarios for toxicity, thermal radiation, and vapor cloud explosion hazards. Each pressure relief system has unique discharge points and receptors that must be defined in order to protect both your employees as well as the surrounding community.
