tional purposes. Acetylene and hand lanterns and Acetylene torch lights, shall be exempted from the provisions of this section, provided any portable Acetylene generating or holding apparatus which does not conform to the provisions of this section, so far as they apply shall not be permitted for lighting any building.

(A) No acetylene generating or holding apparatus shall be installed, or repaired after it has once confined this gas without the assistance of an experienced person holding a license from the Inspector of Buildings therefor.

(B) All apparatus to be used for generating or holding Acetylene shall be so constructed, located and used, as to secure the greatest measure of safety, according to the herein given rules and as may be prescibed by the Inspector of Buildings.

1. Such apparatus shall be made of sufficiently strong material and sufficiently good workmanship to insure stability and durability.

2. No unalloyed copper and no fragile or unstable material shall be used in constructing or connecting such apparatus.

3. The air space in any generating chamber of such apparatus shall be reduced to such dimensions, that the proportions of air in the Acetylene stored therefrom shall not constitute a dangerous mixture while the apparatus is in operation.

4.- Excessive pressure within and escape of gas from the apparatus must be guarded against by approved means.

5. Provision must be made to guard against dangerous development of heat and for the complete submersion in water of the Carbide residuum in any generating chamber before its removal therefrom.

6.-No Acetylene generator shall be fitted with continuous drain connections leading to sewer without means to prevent any undissolved Carbide from passing to said sewer.

7.-Reliefs or safety blow-offs of approved form shall be provided and connected with an escape pipe affording free vent to the outer air, and terminating in an approved hood located at least twelve (12) feet above the ground and remote from windows.

8. A stop cock shall be provided on the service pipe which shall control the outflow of gas from the apparatus; no cock or valve adapted to allow gas or air under pressure to escape into the atmospehre surrounding the apparatus shall be permitted.

(C) All Acetylene generating or holding apparatus, except as herein provided, shall be installed in rooms provided with day light, with approved means for guarding against the freezing of the liquids li contained therein and with suitable ventilation. The apparatus shall be so placed that its working parts shall be easy of access and have free and full play; that no artificial light will be required for adjusting, charging or cleaning same, and that it will not be subject to interference of children or careless persons. To this latter effect a further enclosure permitting free circulation of air shall be provided, if necessary.

(D) No person shall take charge of an Acetylene generating or holding apparatus until he or she has been properly instructed in its operation and in the following rules, which shall be conspicuously posted in the apparatus room in the English and French languages:

1. Calcium Carbide shall be kept in water tight metal receptacles, stored in a dry place inaccessible to water, children or careless persons. Every receptacle in use shall be carefully closed immediately after the required Carbide has been taken out of it. Calcium Carbide shall not be handled near water nor be placed over or under tanks or other vessels containing water, except in proper position on or in the generating apparatus.

2. In case of an escape of Acetylene or of a leak, windows and doors must be opened immediately and free ventilation maintained until the trouble has been fully remedied.

3.-Smoking, carrying a light or fire of any kind near an Acetylene generating or holding apparatus, testing the apparatus or pipe for leaks with a flame, and lighting Acetylene issuing from an outlet not provided with a burner, are prohibited.

4.-In case of accidental freezing of the water in any part of the apparatus only hot water shall be used for thawing same.

5.-All the liquids shall be removed from an Acetylene apparatus intended to remain idle before same shall be exposed to

frost.

6.-All Acetylene generating or holding apparatus, or parts thereof in contact with the gas, shall be removed outside and completely filled with water several times in such a way that all the air therein shall be expelled each time before any repair requiring the use of a hot tool shall be made.

7. No pressure guage shall be allowed to remain connected to any part of the system, unless so arranged, in an approved manner, that gas cannot escape in the event of evaporation of the liquid seal or of derangement of such appliance.

8.-No stove, lamp or other similar gas appliance connected to a combustible gas system by a tube made of rubber, or of other perishable material, shall be allowed to have a cock or valve permitting the gas to remain under pressure in such tube while the gas is not burning.

(E) The manufacture, transportation, storage, sale or use of liquified Acetylene is absolutely prohibited within the limits of the City.

(F) The manufacture, transportation, storage and sale of acetylene compressed in steel cylinders of approved design and construction, up to pressures not exceeding three hundred pounds (300 lbs.) to the square inch, may be allowed to competent persons duly licensed within the limits of the City under a special permit.

(G) The storage and installation for use of the tanks containing acetylene, as specified in sub-section (f), shall be in places approved of by the Inspector of Buidlings.

(H) All Calcium Carbide in transit through the City and in storage must be enclosed in hermetically closed iron receptacles, and plainly marked: "CALCIUM CARBIDE. DANGEROUS IF NOT KEPT DRY, and CARBURE DE CALCIUM.-DANGEREUX A MOINS D'ETRE TENU SEC."
