56A. [ Other safety measures. [Inserted by Notification No. 1950 (LL)/XXXVI-B-2(LL)-54, dated November 2, 1954.]
- In the case of oxygen prepared by electrolytic process for the purpose of compressing, the purity of oxygen shall not fall at any time below 99 per cent by volume.(2)The electrical connexions of the electrolytic cell shall be so arranged as to overrule the possibility of wrong connection of the terminals leading to reversal of polarity.(3)Oxygen and hydrogen pipe shall be painted with distinguishing colours to eliminate the possibility of faulty connections and the connecting of the cells to the right lines shall be carried out by a competent person nominated by the Manager.(4)Samples of oxygen shall be taken and tested for purity at both the ends of the gas-pipes connecting the gas holder and the suction end of the compressor after the supply of oxygen to the gas-holder is cut off completely from the cells by means of a stop-valve. Testing of the gas for purity shall be reported thereafter every hour and records maintained in a register which shall be approved by the Chief Inspector of Factories in this behalf.(5)Each plant shall be provided with at least two gas-holder so that while oxygen of one of them completely isolated from the cells is being compressed, the gas generated at the cells is collected in the other.(6)Testing of purity of oxygen shall be carried out by a competent person nominated by the manager and the person so nominated shall sign the register against each set of readings to certify the correctness of the same.]Excessive Weights[Section 34(2)]
