shall be started and continuously run to their usual running-
capacity for not less than two hours before any person enters

PRECAUTIONS AGAINST COALDUST.
Regulation 155 of the principal regulations is hereby
amended by deleting paragraph (3), and substituting the fol-
lowing paragraphs:—
(3.) The incombustible dust used for the purpose of the
preceding regulation shall contain not less than 50 per cent.
by weight of fine material capable, when dry, of passing a
sieve with 200 meshes to the linear inch (40,000 to the
square inch); provided that if a larger proportion of
incombustible dust is used than is required under the fore-
going regulation, the percentage of fine material aforesaid
contained in the incombustible dust may be reduced propor-
tionately, but shall not fall below 25.°
(4.) For the purposes of testing the composition of the dust
mixture in any part of a road, the following procedure shall
be adopted :—
(a.) Representative samples of the dust shall be collected
from the floor, roof, and sides over an area of road
not less than fifty yards in length.
(b.) The samples collected shall be well mixed, and a portion
of the mixture shall be sieved through a piece of
metallic gauze having a mesh of 28 to the linear inch.
(c.) A weighed quantity of the dust which has passed
through the sieve shall be dried at 212° F., and the
weight lost shall be reckoned as moisture. The
sample shall then be brought to a red heat in an
open vessel until it no longer loses weight. The
weight so lost by incineration shall be reckoned as
combustible matter for the purposes of the test :
Provided that in the case of dusts to which the
foregoing test would not be applicable, the test shall
be such as may be approved by the Minister of Mines.
If any dispute arises as to the test which should
be applied, it shall be determined by the Chief In-
spector.
Representative tests shall be made by the manage-
ment at intervals of not less than six months, and
the results shall be posted at the mine-mouth or
pit-head.
(5.) No dust shall be used for the purpose of complying
with these regulations of a kind which may be prohibited
by the Minister of Mines on the ground that it would be injurious
to the health of persons working in the mine ; provided that
if any dispute arises as to whether the dust is injurious it
shall be determined by the Chief Inspector.
(6.) This part of the regulations shall not come into force
until the 30th September, 1921 ; provided that if it is shown
to the satisfaction of the Inspector of Mines of the district, in
regard to any mine, that it has not been practicable by that
date to obtain the necessary plant for carrying out the regu-
lations, the Inspector may, subject to such conditions as he
thinks fit, allow such extension of time as shall appear to
him to be reasonably required.

PRECAUTIONS AGAINST SPONTANEOUS COMBUSTION OF COAL.
179. The following provisions shall apply to any mine or
part of a mine in which safety-lamps are required by section 40,
paragraph (46), of the Coal-mines Act, as amended, to be
used, and to any other mine where the Minister of Mines
directs that they shall apply in view of the conditions exist-
ing in that mine.
(1.) On the appearance in any part of the mine of smoke
or other sign indicating that a fire has or may have broken out
below ground, every workman other than those necessarily
engaged in dealing with the emergency shall be withdrawn
from the ventilating district or districts affected, and before
any workman is readmitted into the district or districts
affected the manager or underviewer, accompanied by the
fireman-deputy, shall xamine the district or districts, and
shall make a full and accurate report of the condition of the
district or districts, and no workman shall be readmitted
unless the manager or underviewer making the examination
report the mine to be safe. Every such report shall be signed
by the persons making the examination, and shall indicate, if
possible, by means of a plan, the situation of the fire. The
report shall be kept at the office of the mine. The reports
made by the responsible official appointed to supervise the
affected area shall be posted up at the mine-mouth or pit-head
at the end of each shift for the information of the workmen.
(2.) When the existence of a fire has been definitely ascer-
tained, every workman, except those engaged in combating
the fire, shall be withdrawn from the seam in which the fire
exists and from every other seam communicating with the
shaft on the same level, and shall not be readmitted until
an examination has been made and the seam or seams re-
ported to be safe in the manner indicated above :
Provided that—
(a.) It shall not be necessary to withdraw the workmen on
the intake side of the fire if the seam or, in cases to
which proviso (b) applies, the ventilating district in
which the fire exists is naturally wet throughout,
