  • Gas alarm system protects waste treatment staff

    The human nose is particularly sensitive to Hydrogen Sulphide (H2S); a highly offensive odorous gas, reminiscent of rotten eggs. With an odour threshold between 0.005 ppm and 1.5ppm, relatively low levels of Hydrogen Sulphide can result in complaints if industrial plants generate exposure at these levels. A chemical waste treatment plant in the UK has therefore installed a monitoring and alarm ...
