SCHEDULE 4 SCHEDULE IV [See rule 39(2)] Facilities required for cylinders-testing stations 1. Management : 1.1 GeneraL requirements Personal equipment, inspection procedures, recording and organisation shall be adequate and the test station will be operated to give consignment safe- operating con- ditions. The procedures and testing shall ensure that cylinders which fail to meet the requirements and intent of these rules are not returned into normal service. All personnel shall fully recognise their individual respo- nsibilities and that the minimum inspectional requirement shall not be lowered for any reason whatsoever. NOTE- The area of responsibility shall be divided into three separate functions as indicated below. The numbers of personnel empl- oyed shall, however, berelated to the quantum of work. 1.2 Manager.-The manager responsible for the working of the test station shall be properly qualified ; his qualifications shall include training on the dangers associated with gas cylinders, purpose of inspec- tion, test methods, equipment, test requirements, and recording of test results, and he shall have appropriate technical qualification in Mecha- nical or Chemical Engineering. He shall also be conversant with the Codes, Specifications and/or Regulations applying to the cylinders for which the test station is approved. 1.3 Supervisor.- The Supervisor shall possess the following qualifications, namely: (i) have. at least two years' experience in the examination of gas cylinder; (ii) be at least 21 years of age; (iii) be conversant with these rules,Codes,Specifications and/or Regulations applying to the cylinders for which the test station is approved. 1.4 Operator.- - Personnel conducting inspections and tests shall have qualifications and experience suitable for the work on which they are engaged. They shall be trained to understand the dangers associated with gas cylinders and the purpose and method of inspection. 2. Equipment.-2.1 Type of equipment. The test station shall have adequate equipment to carry out inspec- tion and testing of cylinders as required under these rules. It shall contain- (i) One set of these rules, Codes, Specifications and/or Regu- lations applying to the cylinders which the test station is autho- rized to test. All these rules, Codes, Specifications and/or Regu- lations shall be maintained with all current amendments. (ii) Hydrostatic test apparatus comprising pressurizing equip- ment, pressure gauge and volumetric measuring equipment in accor- dance with IS : 5844-Hydrostatic stretch testing of compressed gas cylinders. The apparatus shall be equipped with at least two fifteen cm diameter (minimum) working pressure gauges. (ill) Dead-weight pressure gauge tester of appropriate pressure range or a calibrated pressure gauge of fifteen cm minimum dia- meter covering the appropriate pressure range. (iv) Extra-low voltage lamps to permit adequate internal vie- wing of cylinders and other lamps necessary for closed examination of external surfaces. (v) Straightedges, templates, miscellaneous tools and gauges for measurement. (vi) Weighing equipment, where applicable. (vii.) One set of standard test weights for the weighing machine stamped by the relevant statutory authority. (viii) Adequate cylinder handling equipment. (ix) Adequate cylinder draining equipment. (x) Facilities for internal drying of cylinders. (xi) Marking and stamping equipment. 2.2 Accuracy.- The accuracy of equipment shall be as follows: (i) Hydrostatic test apparatus in accordance with IS: 5844. Volumetric equipment shall be capable of measuring a permanent change in volume of the cylinder under test of the order of 1/20000 of its total capacity. (ii) Weighing equipment error not greater than 0.1 per cent. (iii) Working pressure gauge error not greater than I per cent. (iv) Calibrated pressure gauge error not greater than 0.25 per cent. of the full scale deflection. 2.3 Calibration.- Calibration of equipment shall be carried out at periods not exceeding the following- (i) Working pressure gauge- 3 weeks. (ii) Calibrated pressure gauge- 6 months. (iii) Weighing equipment- checked by test weight daily when in service. (iv) Test weights- 2 years. 3. Working conditions- - Working conditions for the test station shall be conducive to accurate and safe inspection and testing of gas cyli- nders. The test station shall comply with the following conditions: (i) It shall have good lighting to permit ready external exami- nation of gas cylinders, preferably including natural lighting. (ii) It shall have adequate ventilation to remove residual gases from cylinders. (iii) It shall provide sufficient space to permit safe working. (iv) It shall be maintained in a clean dry condition. 4. Condition of cylinders for test: - Cylinders forwarded to the test station shall have first been emptied of their contents and then labelled as "empty", prespective of this label all cylinders other than Cylinders at the manufacturers works shall be presumed to contain gas under pressure and the following precautions shall accordingly be observed- (i) The cylinder contents shall be released in a safe manner keeping in mind dangers associated with the nature of the gas in the cylinder. Cylinders which contain or may have been contami- natedby poisonous or ob-noxious substances shall be emptied only by test stations properly equipped and experienced to handle the particular gas. Such cylinders shall be clearly labelled that they have been contaminated. (ii) The valve shall be opened and if no gas escapes and the port is not visibly blocked, a charge of low pressure nitrogen or other in- inert gas shall be blown into the valve outlet. Discharge of gas after removal of the nitrogen supply indicated the cylinder is empty. When no gas discharges the valves shall be treated as "obst- ructed". Where a cylinder has contained poisonous or obnoxious substances, and the valve is suspected of being obstructed, the gas shall be released within an approved appliance and the valves shall be removed in such a manner that the gas escapes without danger to the operator. (ill) Should the valve be obstructed the contents of the cyli- nder shall be released in a safe manner as stated in (i) above. Work on cylinders containing combustible gases shall be carried out in the open air. NOTE -A suitable method of dealing with a valve in which the spindle cannot be removed is a drill a l/16th in (1.6 mm) diameter hole with a hand dril through the valve body to the gas passage below the spindle sea- ting. Alternatively, a fine-tooth hacksaw may be used. Drilling or sawing must be stopped immediately upon the first sign of escaping gas. A continuous jet of water must be directed on to the cutting tools and the operator must wear protective clothing. 5. Inspection and test- The test station shall adopt procedure which fully comply with requirements of these rules.
