Hazard Analysis (PHA/DHA)

With comprehensive PHA and DHA process safety services, software, and training, ioMosaic makes compliance easy. Our experts are knowledgeable in recognized and generally accepted good engineering practices (RAGAGEP). Each member of our team is a trained and experienced PHA Leader. Our professionals also have extensive experience using various industry-recognized methodologies such as HAZard & OPerability (HAZOP) study, “What-If” Checklist, fault tree analysis, layer of protection analysis, Failure Mode and Effects Analysis (FMEA), and Inherently Safer Technology (IST) analysis. We also provide detailed reporting to document the PHA/DHA identifying any compliance gaps with associated recommendations.

Process Hazard Analysis

A Process Hazard Analysis (PHA) is required by OSHA’s Process Safety Management (PSM) regulation for PSM-covered processes, NFPA 652, NFPA 654 and other NFPA regulations for combustible dust processes. It is critical to pinpoint weaknesses in the design of facilities and processes that could lead to chemical releases, fires or explosions. OSHA’s inspection results from the National Emphasis Programs launched for refineries in 2007, and the chemical industry in 2009, demonstrate that the quality of PHAs continues to be a weak link in the management of process safety issues. Our engineers have completed hundreds of PHAs for oil fields and pipelines, refineries, pulp mills, solar power plants, coal-fired power plants, pharmaceutical facilities, LNG plants, sterilization facilities, explosive manufacturers, specialty chemical plants, and many more businesses.

Dust Hazards Analysis

A Dust Hazard Analysis (DHA) is required by NFPA per their 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 is applicable to any facility that handles combustible dust or particulate solids. For more than a decade, our engineers have performed these types of analyses at a wide range of facilities, including specialty chemical, food, pharmaceutical, and plastic.

Construction Hazard Analysis

A Construction Hazard Analysis (CHA) is a best practice process to successfully identify and manage process safety type risks associated with construction, high risk maintenance and non routine activities on or near process safety or other high risk assets. This type of process has been recommended by the Chemical Safety Board (CSB) after a number of high profile process safety incidents with inadequate or no construction risk management resulted in catastrophic consequences including loss of life. A CHA can help the asset owner and operator understand the risk that internal resources and contractors may take at their facilities and make decisions to manage it before the work is started so that they can stay within their company’s risk profile and minimize the potential for a process safety incident. ioMosaic is very experienced in this technique and can lead your team to the safe completion of your project.

Hazard Analysis Tools

Our software Process Safety Office® PHAGlobal® is the most useful and cost-effective PHA/DHA tool on the market. The process hazard assessment documentation software simplifies the recording of findings and tracking follow-up from PHAs. It also eliminates the need for any special application software when working with the results. PHAGlobal® delivers professional, branded reports and make it easier to comply with codes and standards, such as OSHA PSM, EPA RMP and NFPA, that require PHAs.
