Process Hazard Analysis

PHA a systematic effort designed to identify and analyse hazards associated with the processing or handling of highly hazardous materials; and a method to provide information that will help workers and employers make decisions that will improve safety. PHA is a proactive and structured approach by your process operations to understanding what can go wrong, how likely it is to go wrong, and what steps are necessary to prevent or mitigate undesired consequences. Arvika PHA team specialists can help you select the PHA method best suited to your specific processes and operations. We are well-versed in the complexities of hazards analysis due to our many years of process safety experience. We can assist you in accumulating the necessary process safety information, including hazardous material properties such as combustibility, flammability, explosively, reactivity, self-heating, toxicity, and electrostatic properties, etc, as well as assembling and leading the PHA team, drawing up reports, and documenting outcomes.


  • Identification of error sources and estimation of probabilities of occurrence
  • Process safety specialists with a strong industry background
  • Internal workshops to train employees to manage risk and be effective PHA leaders

Arvika RMS are specialists in the  field of process hazard analysis methods, including hazards and operability studies (HAZOP), failure mode and effect analysis (FMEA), fault tree analysis (FTA), layers of protection analysis (LOPA), and more.

Qualitative & Quantitative Risk Analysis

A Quantitative Risk Assessment (QRA) is a formal and systematic risk analysis approach to quantifying the risks associated with the operation of an engineering process. A QRA is an essential tool to support the understanding of the exposure of risk to employees, the environment, company assets, and its reputation.

What is the importance of quantitative risk assessment?

Quantitative risk analysis provides more objective information and accurate data than qualitative analysis because quantitative risk assessment is based on realistic and measurable data used to calculate the impact values that the risk will create with the probability of occurrence.

What are the methods for quantitative risk assessment

There are four classes of quantitative sensitivity analysis tools. These are scenarios, mathematical, statistical, and graphical analysis


Steps for quantitative analysis
Steps of Data Analysis

  • Determining the objective.
  • Gathering the data.
  • Cleaning the data.
  • Interpreting the data.
  • Sharing the results.

Benefits of Performing a Quantitative Schedule Risk Analysis

  • As with any analysis, the output is only as good as the input. ...
  • Defining the Probability of Success
  • Identify High-Risk areas.
  • Mitigation.
  • Ongoing Risk Management.
  • Improve Client Confidence.
