Process Hazard Analysis
A PHA is an organized and systematic approach to the management and control of process hazards. It identifies potentially hazardous situations, broadly categorizes the severity of the hazard, and provides the understanding of the hazard scenario needed to allow appropriate actions to be taken. PHAs help manage risks associated with potential unwanted events such as explosions, fires, and toxic releases. Various techniques such as HAZID, What-If Analysis, HAZOP, and LOPA are utilized to perform these analyses, ensuring a comprehensive assessment of potential hazards and the implementation of effective safety measures.
Process Hazard Analysis
with Smith & Burgess
At Smith & Burgess, we maintain a staff of experienced facilitators with diverse industry backgrounds to ensure thorough evaluations of all possible events and develop attainable recommendations for clients to reduce their risk liabilities. Recognizing the importance of justifying key assumptions and applying semi-quantitative methods, we can tailor our approach to address specific client needs.
Our Methodology
Our comprehensive services cover initial design, completed facilities, revalidation of existing studies, and control system reviews. We ensure that every aspect of the process is meticulously analyzed to identify and mitigate potential hazards. Our approach is designed to be flexible and adaptable, catering to the unique requirements of each client and their specific industry needs.
Techniques Used in PHAs
HAZID
(Hazard Identification)
A systematic process to identify hazards in a system, process, or activity, focusing on early detection and prevention. It typically involves a team of experts who brainstorm and document potential hazards based on experience and known risk factors.
What-If Analysis
A brainstorming technique where potential deviations from normal operations are proposed to identify possible hazards and consequences. This method helps uncover unexpected issues by posing "what if" scenarios that promote creative thinking to foresee and mitigate risks.
HAZOP
(Hazard and Operability Study)
A detailed and systematic technique using guide words and nodes to identify potential hazards and operability problems in a process. HAZOP involves a multidisciplinary team reviewing process diagrams to find deviations from the design intent that could lead to hazardous situations.
LOPA
(Layer of Protection Analysis)
LOPA is a semi-quantitative tool that assesses the risk reduction provided by various layers of protection in a process. It quantifies the effectiveness of safety systems and helps in making decisions about additional safeguards needed to reduce risk to acceptable levels.
Why Perform a PHA?
Performing a Process Hazard Analysis (PHA) is essential to identify, assess, and prioritize potential hazards for control within industrial processes. Regulatory compliance standards, such as OSHA 29 CFR 1910.119, mandate that PHAs be conducted to prevent accidents and protect workers. PHAs must be completed and maintained on a five-year revalidation schedule. Good industry practice also shows that applying the PSM/RMP principles to non-PSM/RMP regulated facilities provides a better, safer workplace where potential safety issues are understood and controlled.
