Ammonia Detection

The different advantageous embodiments provide for identifying gas leakage in a platform. A processor unit identifies a rate of the gas of the substance leaking from a container in a first compartment for a platform. The processor unit also identifies an amount of gas that has leaked from the container at a selected time based on the rate of the gas of the substance leaking from the container and a total time. The processor unit identifies an amount of the gas of the substance present in a number of compartments associated with the first compartment using the amount of gas leaked from the container in the first compartment and a pressure for each compartment in the number of compartments. The processor unit determines whether the amount of gas in at least one of the first compartment and the number of compartments is outside of a desired amount for the gas.
