Identify Hazards and Manage Risk With Comprehensive PHA and Risk Assessments

Process Hazard Analyses (PHAs) are central to identifying risks and preventing incidents in industries handling hazardous chemicals. We have facilitated hundreds of PHAs, Layers of Protection Analyses (LOPA), and other risk evaluations across oil & gas, chemical, and manufacturing facilities. Our experts tailor methods to each client’s processes and lifecycle stage - whether design, startup, revalidation, or decommissioning - to ensure meaningful results that drive safer, more reliable operations and strengthen overall Process Safety Management (PSM) programs.

PHA & Risk Assessments FAQs

A PHA is a systematic method for identifying and analyzing potential hazards associated with processes involving hazardous chemicals, required under OSHA’s Process Safety Management (PSM) standard.

PHAs help prevent incidents by identifying hazards, evaluating safeguards, and recommending improvements, supporting safer operations and regulatory compliance.

PHAs are critical for industries handling hazardous chemicals, including oil & gas, petrochemicals, chemicals, and manufacturing.

OSHA requires PHAs to be revalidated at least every five years, or sooner if significant changes occur in processes, equipment, or operations.

We apply methods such as HAZOP, LOPA, FMEA, What-If Studies, and project-specific PHAs, selecting the right approach based on client needs and process complexity
