Hi All
Question related to calculating the extent of zones in a HAC study. IEC60079.10.1:2022 states that the chart (Figure D1) for estimating hazardous area distances only applies for high dilution situations. What are common available tools for determining the extent in medium or low dilution situations. Or is it better to use just professional judgement? Note that the IEC standard provides no tools for medium and low dilution situations.
Thanks in Advance for any suggestions!
