Our engineers have completed hundreds of PHAs, DHAs, and CHAs for oil fields and pipelines, refineries, pharmaceutical facilities, LNG plants, sterilization facilities, explosive manufacturers, specialty chemical plants, pulp mills, solar power plants, coal-fired power plants, and many more businesses. We can help you comply with internal company standards and global industry standards.
A PHA is required by OSHA’s Process Safety Management (PSM) regulation for PSM-covered processes and NFPA regulations. It is critical to pinpoint weaknesses in the design of facilities and processes that could lead to chemical releases, fires, or explosions. ioMosaic delivers practical, locally compliant solutions to our clients' safety and risk concerns. Protect your most important resources ― your people, your plant, your stakeholder value, and our planet.
A DHA is required by the NFPA 660 Standard for Combustible Dusts, applicable to any facility that handles combustible dust or particulate solids. A catastrophic incident can easily occur without risk management. With a quality DHA from ioMosaic, you can ensure that any design flaws are surfaced and that recommendations are made to address unacceptable risks identified during a DHA.
A 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. A CHA from ioMosaic can help you understand the risks and make decisions to manage it before the work is started to minimize the potential for an incident.

In accordance with OSHA PSM regulations, a global manufacturer of industrial gas needed to revalidate their Process Hazard Analysis (PHA) using an on-site and remote approach. This PHA study focused on identifying any significant safety and environmental impacts associated with the facility's liquid nitrogen / gaseous nitrogen system, and the gas, monitoring, and ventilation system. Read the case study to learn the advantages of working with ioMosaic.
An international personal products manufacturer needed to complete process hazard analyses of their alcohol processes to meet regulatory and company requirements. The process hazard analyses could not be completed until all necessary process safety information was compiled.
It is critical to identify flaws in the design of facilities and processes that may result in chemical releases, fires, or explosions. Watch a demo of PSMPro and see how this powerful suite of time-saving tools can help you conduct a quality risk analysis. You'll love this software's many features, including a variety of pre-populated compliance templates.
Despite investment of considerable resources to conduct process hazard analyses (PHAs), many companies are still experiencing a high rate of incidents and find that the causes of these incidents have not been identified and/or addressed in their PHAs. Read this white paper to learn why quality issues can have a serious impact on the effectiveness of PHAs.
