What defaults templates are available in PHAWorks Lite?

Default templates are provided to use in creating projects for a variety of study methods. A short description is provided of the study method for each template.

Projects can be created by selecting a study method and clicking the Create New Project button which opens the Project tab allowing data for the project to be entered. You can also create a new project by selecting a default template from File / New Project.

Projects created using default templates use the program’s default settings for the template, such as field and column names, column widths, etc. Settings can be changed and are saved with the project file when it is saved.

Included templates:

  • HAZOP (Parameter-Based, Traditional) - Hazard and Operability (HAZOP) studies are used to identify hazard scenarios with impacts on people and the environment as well as operability scenarios where the concern is the ability of the process to function. The method focuses on investigating deviations from the design intent of the process by applying guide words to process parameters to generate deviations.

  • HAZOP (Procedural) - Procedural Hazard and Operability (HAZOP) studies apply the HAZOP method explicitly to procedures to identify ways in which deviations from the procedures may occur.

  • What-If - What-If studies involve posing questions relating to initiating events to identify hazard scenarios for a process. The PHA team brainstorms the questions.

  • What-If / Checklist - What-If / Checklist studies involve posing questions relating to initiating events to identify hazard scenarios for a process. The PHA team starts with a prepared list of questions, although almost always additional questions are added as a study proceeds.

  • MHA - Major Hazard Analysis (MHA) is used to identify hazard scenarios involving fires, explosions, toxic releases and reactivity excursions. MHA employs a structured brainstorming approach to identify loss of containment scenarios. A checklist provides guidance to the team and helps to assure completeness.

  • FMEA - Failure Modes and Effects Analysis (FMEA) is a hazard evaluation procedure in which failure modes of system components, typically, process equipment items, are considered to determine whether existing safeguards are adequate. A FMEA becomes a FMECA (Failure Modes and Effects and Criticality Analysis) when a criticality or risk ranking is included for each failure mode and effect.

  • PrHA - Preliminary Hazard Analysis (PrHA) is used to identify the hazards of a process and the hazardous situations they may produce. Possible causes, consequences and recommendations for protective measures are addressed. A criticality ranking may be assigned and used to prioritize protective measures. Typically, PrHA is used to evaluate and prioritize hazards early in the life of a process as a precursor to more detailed hazard analysis studies.

  • HAZID - Hazard identification (HAZID) studies are used to identify the hazards present in a process. Usually, possible means of eliminating the hazard or controlling the risk also are identified.

  • DHA - Dust hazard analysis (DHA) studies are used to identify combustible dust hazards, such as fires, deflagrations, and explosions, and their possible impacts on people, facilities, and the environment.

  • Checklist - A checklist used as a hazard evaluation procedure employs lists of questions relating to process safety to identify concerns and help to determine whether existing safeguards are adequate. Checklists are used to identify common hazards and ensure compliance with procedures, codes of practice, regulations, etc. Checklist questions are based on experience and knowledge of safety issues for the process and applicable codes, standards and regulations.

  • Job Safety / Hazard Analysis - Job Safety Analysis (JSA), or Job Hazard Analysis (JHA), is used to help to reduce injuries and illnesses in the workplace. Hazards associated with each task / step involved in performing a job are identified and controls are prescribed for each hazard.
