Gas Hazardous Areas – Kauri

Fonterra Kauri Natural Gas Hazardous Area Classification

Natural Gas represents a significant risk across some industrial sites because mains gas is piped extensively and used for raising process steam and hot water in packaged boilers. Simple methods of classification can over-assess or under-assess the risks, leading to underestimation of where the real risks are, or unnecessary over-expenditure where there are less risks. Our approach for these areas is to use the latest empirically based methods in hazardous area classification, including calculation tools, and to analyse the ventilation in the key areas. This approach enabled us to produce more accurate zone drawings and identify ventilation parameters and controls for the Kauri site.
