     in the derrick, the buildings connected therewith, and in all
     working-places.

244. All buildings in the precincts of any well or oil-tank
     shall be covered with fireproof material, and spark-arresters,
     not constructed of wire gauze, shall be placed on all smithy
     chimneys.

245. Within the precincts of any well no person shall sleep
     in any other than a recognized dwelling-house.

246. No person shall be admitted to any building used in
     connection with well operations, except on business.

247. There shall be submitted to the Inspector for his
     approval, not less than one month previous to the commence-
     ment of the installation of any gas or electrical motor or
     dynamo, unless required for lighting purposes only, complete
     working drawings and specifications of such installations.

248. All parts of electric installations shall be covered or
     otherwise protected from accidental injury.

249. Electric installations, when not specially provided for
     in these regulations, shall be subject to the Regulations for
     the Installation of Electricity, under the Mining Act, 1908.

250. There shall be attached to every gas-engine an auto-
     matic starting-device.

251. All moving and rotating parts of engines and other
     machinery, also all steam-pipes and electric-current conduc-

     which may be seen or heard by the workmen employed
     thereon.

Oil and Gas Tanks.

258. Every oil-tank at well operations shall be efficiently
     protected and closed. Wooden tanks, if not sunk into the
     ground, shall be completely embanked with earth; the roofs
     of every tank shall be fireproof, and shall contain a strong
     fireproof and hinged door provided with a lock.

259. Iron tanks shall be encircled by a high and strong
     embankment, constructed at an adequate distance from such
     tank. The open space between embankment and tank shall
     be kept clean and free from obstruction.

260. The roof of each tank from which gases are not led
     away through pipes shall contain a ventilator, which shall be
     covered with a copper gauze having at least 784 apertures per
     square inch. The cocks and valves of the oil-outlets of every
     tank exceeding 3,000 gallons in capacity shall be enclosed
     in masonry boxes with hinged lids; every tank of such
     capacity shall be provided with an arrangement by which
     the outlet-pipe may be closed from the inside of the tank.

261. To all tanks exceeding 16 ft. in depth there shall be
     attached a strong iron ladder. If the roof of the tank is con-
     cave, access to the manhole shall be secured by means of iron
     railing.

262. Every iron tank exceeding 3,000 gallons in capacity
     shall be provided with a lightning-conductor, which shall be

263. Oil which has consolidated shall be heated with steam
     only; fire on no account shall be used.

264. A burning tank shall not be extinguished with water,
     but oil within the tank shall be withdrawn through the outlet-
     pipes to other tanks or pits. Smaller tanks or barrels, if
     burning, shall be covered with sand, wet sacking, or other
     suitable material.

265. No oil-tanks exceeding 3,000 gallons in capacity shall
     be constructed or placed within 40 yards of any building
     containing a fire, or any public road. For any smaller tank
     the distance shall be at least 20 yards. This regulation shall
     not apply to any tank in position on the 3rd August, 1915.

266. The cleaning of all tanks shall be carried out in the
     following manner: Wooden oil-tanks and oil-pits shall, after
     the extraction of the oil, be partially uncovered and venti-
     lated for at least twenty-four hours, and if a steam boiler is
     available the tank shall be blown out with steam. The
     cleaning may be proceeded with afterwards, from the outside
     if possible. If cleaning is indispensable and cannot be done
     from the outside, unless self-contained breathing-apparatus
     is worn, only one workman shall be employed in any tank at

one time, in which case the workman shall be secured by a
rope, and shall be attended by a supervisor and another
workman.

267. Outlets of adequate dimensions for ventilation shall
     be placed in the roof and near the bottom of every iron tank.
     The ventilation and blowing-out of every larger tank shall
     be continued until it is safe for the workmen to enter.

268. Every well in which boring has been suspended, and
     which produces a considerable volume of gas, shall have its
     outlets so constructed that gas may be conducted therefrom
     through pipes to prepared gasometers. No gasometers shall
     be constructed within 33 yards of any operative well, building
     containing fireplace or stove, or any public road.

269. A separate gasometer shall not be compulsory if oil
     and gas is conducted from a well to a separator which is
     more than 33 yards from any operative well, building having
     a fireplace or stove, or a public road.

270. If a pipe-line connects with a gas-main of equal
     diameter, conveying gas from another gasometer, a separate
     gasometer is not compulsory.

271. The above regulations do not apply to gasometers
     which are in existence on the 3rd August, 1915. Gasometers
     and gas-separators shall be of adequate capacity and strength,
     and shall be provided with two approved safety-valves.

272. Gas-pipes from any gasometer to a boiler shall be free
     from oil.

273. Every pipe-line connecting any well with a gaso-
     meter or separator shall be provided near such gasometer
     or separator with a valve, which shall be closed in the event
     of the pipe-line becoming disconnected.

Heating of Steam Boilers.

274. All gas used for boiler-heating shall be dry or free
     from oil.

275. Gas-pipes shall be maintained in good repair and
     provided with valves or cocks, placed both within and without
     the boiler-house, in proximity to the gasometer.

276. There shall be placed in each pipe-line from the gaso-
     eters two safety wire gauzes having at least 784 apertures
     to 1 square inch, at each side of which there shall be valves
     for shutting off the supply of gas. All gauzes shall be cleaned
     periodically.

277. The conveyance of gas direct from any well to a
     boiler is prohibited.

278. After every stoppage, previous to turning on gas
     for steam-production in a boiler-house, a fire shall be made
     in the firebox to prevent the forming of an inflammable
     mixture of gas and air. The cock of the gas-pipe line shall
     be opened gradually.

279. The spraying system only shall be permitted when
     oil is used for heating boilers.

280. For storing fuel oil there shall be erected, at least
     11 yards from the boiler-house, two tanks, one above the
     other, together not exceeding in capacity 7,000 gallons. In
     the construction of these tanks the following specification
     shall be observed:—

(a.) The upper tank, from which oil flows by gravitation
to the sprayer, shall be completely airtight, and
provided in the top with an opening for the escape
of gas, which shall be protected with wire gauze.
This tank shall be filled only through the pipe-line.

(b.) The upper tank shall be connected to the lower tank
by an overflow-pipe.

(c.) There shall be attached to the bottom of the upper
tank a sludge-pipe, which may be opened for clean-
ing purposes.

(d.) The tanks shall be so arranged that the ground in the
vicinity shall be kept free of oil, and that the sprayer
will receive nothing but pure oil.

(e.) The pipe through which the oil flows to the sprayer
from the tank shall be kept at a suitable height
above the bottom of the tank, and shall have its
inlet, in the interior of the tank, protected with a
wire gauze. Outside of the tank, but in proximity
to it, this pipe shall be provided with a valve.

(f.) The pipes which convey the oil and steam to the
sprayer shall both be placed on the same side of
the boiler. For regulating the flow of oil and
steam such pipes shall be provided with valves
which may be safely manipulated.

(g.) The arrangements and connections of all oil-pipes shall
permit them to be blown out with steam.

(h.) All pipes and fittings shall be tightly joined.

(i.) All openings in the firebox and its door, with the
exception of the door of the ashbox, shall be pro-
vided with gauze safety protectors containing at
least 784 apertures per square inch.

(j.) Unless the wall of the boiler-house opposite the door
of the firebox is made of fireproof material it shall
be covered with sheet iron.

(k.) For covering spilled or burning oil there shall be kept
in the boiler-house, or in proximity thereto, an
adequate supply of dry sand.
