Hazard Analysis (PHA / DHA)

ioKinetic's specialists and  process safety experts have facilitated hundreds of PHA’s and DHA’s worldwide, in virtually all sectors of the process and processing industries. Our process safety leaders (and facilitators) are chemical or process engineers with a high level of process safety expertise and knowledge, with many years of experience leading PHAs and DHAs in industry. We can facilitate PHAs and DHAs, in a number of languages. Our worldwide presence and project work helps ensure our knowledge of local codes, standards, and intimate knowledge of cultures.


Process Hazard Analysis (PHA) is a key requirement of OSHA’s Process Safety Management (PSM) standard, 29 CFR 1910.119 and EPA’s Risk Management Program (RMP) rule, 40 CFR Part 68. These regulations require that PHAs address toxic, fire, and explosion hazards resulting from specific chemicals and their possible impacts on employees, the public and the environment. Therefore the process hazard analysis methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process.


Dust hazards analysis (DHA) is required by NFPA in their recent standard, NFPA 652, Standard on the Fundamentals of Combustible Dust, thus making it RAGAGEP (recognized and generally acceptable good engineering practice) for the regulatory community. This NFPA standard applies to any facility handling combustible dust or combustible particulate solids. Although a relatively new term, DHA, application of hazard analysis to dust processing facilities is not new. A pioneer in DHA, ioKinetic engineers have been performing these types of analyses for almost 10 years at a wide variety of facilities, including specialty chemical, food, pharmaceutical, and plastic. We have developed a unique checklist-based approach that ensures that processes are evaluated against current codes and standards in a timely and efficient manner.


A key differentiator and value add to being able to streamline and conduct PHAs / DHAs timely and reliably is our exclusive use of the Process Safety Office™ PHAGlobal® software component, allowing any PHA / DHA to be readily documented.
