(d) the mixture shall not be subjected to a pressure exceeding 1.55 kg|em2- (1550 cm. water column).
(1) declares that acetylene,
(a) When liquid, or
(b) when subject to any pressure, or
used | removed and must stop generating imme- diately the gas delivery is closed, or the gas holder is filled
4. The apparatus shall have an efficiency of at
least 90 per cent.
5. The temperature of any part of the apparatus when working shall not exceed 80 degree C. Suit- able means for ascertaining the temperature of those parts of apparatus where heat is liable to be generated shall be provided :
Provided that if it be shown to the satisfac- tion of the Chief Controller that a higher tem- perature is necessary in any generating apparatus and that such higher temperature may be used without danger, the Chief Controller may allow the use of higher temperature under such condi- tions as he may specify.
6. (a) The apparatus used shall not be made to work at a pressure exceeding 0.15 kg[ cm2 (150 cm water column) :
Provided that if it be shown to the satisfaction of the Chief Controller that a higher pressure is necessary in any generating apparatus and that such higher pressure may be used without danger, the Chief Controller may allow the use of higher pressure upto a. maxi- mum of 1.55 kg|cnr (1550 cm water column) under such conditions as he may specify.
(b) In the use of the apparatus, regard shall be had to the danger of stoppage of pas- sage of the gas and consequent increase of pressure (i.e. even if the gas supply be cut off or any of the pipes become blocked, the pressure in the generator must not exceed its design working pres- sure^.
7. (a) Adequate precautions shall be taken to prevent any escape of gas from the appa- ratus.
(b) Gas holders shall be fitted with blow oil pipes carried upto a suitable point in the open air. The inlet and outlet of gas holder shall be provided with shut-off valves which can be easily closed in an emergency.
8. (a) The carbide shall be completely decom- posed in the apparatus, so that the lime sludge discharge therefrom shall not be capable of generating more gas.

(b) The apparatus shall give no tarry or other heavy condensation products from the decomposition of the carbide.
9. (a) An open tank shall be provided in the open air for the reception of all residue and such residue shall remain for at least ten hours in not less than four times its bulk of water in such tank.
(b) Precautions shall be taken to prevent any lime sludge from being discharged into the drains.
(c) No source of ignition shall be brought within 9 metres from a tank used for reception of lime sludge.
10. An apparatus shall have an efficient arrange- ment capable of effectively preventing a flash back from the acetylene delivery pipe to the generator or to the gas holder, as the case may be.
11. All electrical motors, lights, switches and other fittings inside a shed housing an apparatus for acetylene generation and within 15 metres of such shed shall be of flame proof construction conforming to IS : 2148 and of a type approved by the Chief Controller.
12. (a) Acetylene generating apparatus shall be installed in a lightly constructed shed made of suitable non-flammable mate- rials.
(b) The shed shall be adequately ventilated near the ground level and near the roof.
(c) A concrete floor covered with suitable conductive material and raised at least 60 cms. above the ground level should be provided,
(d) Escape doors must open outwards and give direct exit to the open space. Their position and number must be such as to provide adequate means of exit in the event of an emergency.
13. The shed housing an apparatus shall main- tain distance not less than 30 metres from an Oxygen manufacturing plant building, 90 metres from an air-intake point, 9 metres from sludge tank and 15 meters from) any other protected works :
Provided that dissolved acetylene cylinder fill- ing-cum-storage shed and carbide storage shed may be adjoining the shed housing an apparatus for acetylene generation and in such case the above mentioned distances shall be observed from the entire building.
6 THE GAZETTE OF INDIA : EXTRAORDINARY [PART II—SEC. 3(i)]14. All apparatus, machinery and other equip- ment shall be efficiently earthed at all times. The earthing connections should be tested at least once in a year and record of all such tests maintained.
15. Nothing in conditions 11, 12, 13 and 14 shall apply to an apparatus of a design requiring charge of carbide of calcium not exceeding 2 kgs. at any one time provided the same is kept in a room forming part of building with a suitable exit leading to open spacelroad.
16. No part of an apparatus or connected dis- tribution system shall be opened without bringing it down to the ambient temperature and no repair with flame or heat shall be carried out unless the apparatus and connected distribution system and the surroundings are made free of acetylene gas. All repairs Shall be carried out under the super- vision of an experienced person.
17. Instructions as to the use of the apparatus shall be prominently exhibited on or in close proxi- mity to the apparatus.
