WebIncreasing population and urbanization have direct consequences on the sewer functioning. In order to identify and quantify gases and VOCs likely to be present in the sewers, methodological studies of sampling in sewer using airbags, canisters and adsorbent tubes were assessed, and methods of analysis by GC-MS were developed. WebHigh pressure fans present a risk of phosphine combustion and hence fire. 9.The current recommended dosage rate for phosphine is 2g of gas/ton or 1.5g of gas/m3(3g of aluminum phosphide = 1g of phosphine gas). However, recommendations do change and it is important to check them from time to time.
