What is Hazcalc?

Hazcalc is an online platform or tool for hazardous area classification of flammable liquids and gases (e.g. hydrogen, methane etc.) according to IEC 60079-10-1.

It's an easy to use tool with an extensive help function and user manual available. Assessments of several release scenarios can be made and the results are stored online. A report function is available and the results, including an image, graphs and when applicable, company logo, can be printed.

The tool is very helpful for e.g. HSE/ATEX-consultants, -managers and -inspector and e.g. for process- and I&E engineers. It can be used for hazardous area classification (HAC) for existing installations and for new installations during e.g. engineering phase and/or commissioning phase.

The key benefits of the tool are:

- time-saving due to incorporated substance database, automated calculations and graph drawings;

- time-saving e.g. due to easy copy, duplicating and editing function of assessments;

- reduction of faults in calculations;

- professional report function with own company logo;

- extensive knowledge of the IEC standard not necessary: guidance and help function is incorporated within Hazcalc;

- reduction of the size of hazardous areas due to the calculation of evaporation in dedicated and customized scenario's;

- prevention of unnecessary Ex equipment due to realistic hazardous areas compared to direct example approach.
