Process Hazard Analysis (PHA)

Gexcon’s consultants have years of experience in performing Process Hazard Analysis and can assist you at all stages of your engineering and management control process from concept design, process development, facility safe operation, and initial hazard evaluation to continued safe operability of your facility.

Identify, evaluate and mitigate potential hazards by using process hazard analysis techniques within your facility.

Process Hazard Analysis is a systematic approach adopted within process industries. Its primary purpose is to identify, evaluate, and effectively mitigate potential hazards intrinsic to operational activities. This approach, commonly referred to as PHA, is typically executed during the initial phases of facility design, construction, or modifications. Its overarching goal is to ensure both the security and robustness of the process.

Process Hazard Analysis can significantly reduce risks linked to human health, process downtimes, property damage, and issues pertaining to product quality originating from equipment malfunctions, human errors, and even external events.

Upon identification of hazards, a thorough risk assessment is conducted to evaluate the magnitude, probability, and plausible consequences of each identified risk.

Guiding you through the process to find the optimum solution for your safety needs

Process Hazard Analysis (PHA) methods are fundamentally qualitative in their approach.  The choice of the PHA method depends on the nature of the process, the industry, and the specific objectives of the analysis. Often, a combination of methods may be used to ensure a thorough and comprehensive assessment of process hazards. In navigating these considerations, selecting the most fitting PHA method ensures a thorough evaluation tailored to the specific characteristics and history of the process in question.


Process Hazard Analysis (PHA) is typically conducted by a multidisciplinary team of professionals with diverse expertise. The composition of the team ensures a comprehensive and thorough examination of the process and its potential hazards. 


Team members will include Process Engineers, Safety Engineers, Chemical Engineers, Instrumentation and Control Engineers, Operations Personnel, Maintenance Personnel, Environmental Experts, Health and Safety Professionals, Management Representatives and a PHA Facilitator or Lead.
