Process Hazard Analysis (PHA)

Process Hazard Analysis (PHA) is required by federal regulations such as OSHA Process Safety Management (PSM), EPA Risk Management Plan (RMP), and state regulations such as the California Accidental Release Prevention Program (CalARP) and California OSHA Process Safety Management (Cal/OSHA PSM).

How Process Hazard Analysis Helps Chemical Processing Companies

PHA is a vital component of PSM, aiming to identify process hazards, evaluate risks, and enhance safety for both people and the environment while ensuring business profitability.

number 1

Risk Identification and Mitigation

Conducting PHAs helps identify and assess potential risks within a system or process. By systematically examining each step, companies can proactively implement measures to mitigate or eliminate hazards, ensuring a safer working environment.

number 2

Regulatory Compliance

PHAs are often a regulatory requirement in industries dealing with hazardous chemicals. Conducting these analyses helps companies comply with relevant regulations, avoiding legal issues and demonstrating a commitment to safety standards set by authorities.

number 3

Improved Decision-Making

The PHA encourages a deeper understanding of the system, fostering informed decision-making. Companies gain insights into potential vulnerabilities and can make strategic adjustments to enhance operational efficiency, reliability, and overall safety.

PHA Facilitation

Saltegra is experienced in PHA having facilitated studies across a broad range of industries. Our sessions are detailed, engaging but succinct. Our approach follows the typical HAZOP methodology; however, we also utilize the latest available innovative technologies and information from the industry, as well as strategies and techniques borrowed from other industries. This allows us to efficiently facilitate studies while reducing session times by as much as 30%.

With our experience, we have helped clients write PHA standards which include consequence development guidance for consistent studies across different sites.


  • Hazard and Operability (HAZOP) Study
  • What-if? / Checklist Review
  • Failure Mode and Effects Analysis (FMEA)
  • Layer of Protection Analysis (LOPA) / Safeguard Protection Analysis (SPA)
  • SIL Selection/Assignment as per ISA 84 / IEC 61511

PHA Preparation Support

Remove the busy work from your PSM group and let us handle the preparation. Saltegra’s experience over the years of facilitating PHA and LOPA studies has allowed us to developed systems and techniques to efficiently get the deliverables ready for you.

Some companies use multiple facilitators for their PHAs, therefore the value of having us complete the preparation work allows for consistent preparation documentation based on your requirements. We will also work with the facilitator to ensure we capture their specific requirements.


5-Year Revalidation PHA

Compliance with federal and state regulations does not conclude after the initial PHA. PHAs must be revalidated regularly, typically every five years or when a major change occurs within the unit. Saltegra Consulting LLC offers 5-year revalidation, management of change (MOC), and design and implementation PHAs to our clients.

Process Hazard Analysis (PHA)


The aerospace industry makes use of different combustible chemicals that can endanger the lives of people and cause severe environmental damage if mishandled. Chemical process safety is crucial to prevent such incidents. Saltegra Consulting LLC provides consulting services to help you ensure proper safety programs are in place.

Process Hazard Analysis (PHA)


The biogas/biomass industry is concerned with the use of renewable energy sources from organic matter. Companies in this industry typically utilize different chemicals to convert agricultural waste into biofuel. Saltegra Consulting LLC can help these companies keep their workplaces safe through chemical process safety solutions.

Chemical Manufacturing

The chemical manufacturing industry is a broad field that encompasses the research, mass production, and distribution of various substances that other sectors will use. To prevent the accidental release of the toxic, flammable, and explosive compounds utilized in their operations, chemical process safety programs are essential.
