                      (NOTE)
                      1. Where the discolouration is over the scale, non-reacted Hydrogen sulphide remains in the pump. This residual
                      Hydrogen sulphide is not exhausted even if the pump handle is pushed back, and it still remains in the pump.
                      When the handle is pulled next, it is exhausted toward the operator from the stopper side of the pump.
                      Accordingly, air purging of the pump inside by pulling/pushing the handle several times should be done in
                      fresh air where there is not Hydrogen sulphide, because Hydrogen sulphide is very toxic. During the air
                      purging, protection apparatus such as a gas mask should be worn.
                      2. Maximum sampling volume of the gas shall be approximay 70mr.
