During November and December of last year I visited all the
Underground Bakehouses in company with the Sanitary Inspector, and
on the 9th December I laid before the Sanitary Committee a full
Report thereon, with the following model recommendations for making
them absolutely sanitary :—
Capacity.—The bakehouse must have a capacity of not less than 1,000 cubic feet.
Floor Space.—The floor space must not be less than 125 square feet.
Height.—The bakehouse should be in every part thereof 8 feet high, measured
from the floor to the ceiling.
Ceilings. —All ceilings, beams, and joists to be thoroughly scraped and cleansed,
and to be match-boarded with tongued and grooved match-boarding, or lathed and
rendered in Portland cement or similar damp-proof and impervious material, worked
to an even and polished surface and limewashed.
Walls.—All walls to be damp-proof, and to be maintained in such condition.
All projections and irregularities in existing walls to be removed, and all hollows and
crevices to be filled up with suitable material. The joints of all walls (except external
walls) to be raked out, and the walls hacked over and rendered with Portland cement
and sand, mixed in the proportions of one part Portland cement to three parts of
clean, sharp sand, and such rendering to be left¾ inch thick at all points and finished
to a smooth and polished surface.
Note.—White glazed bricks, tiles, or opalite are preferred.
Floors.—The whole of the existing floors to be taken up and re-formed and
re-laid, where necessary, 6 inches thick over the entire surface with Portland cement
concrete, mixed in proportions one part Portland cement to five parts of broken stone
or bricks and one part clean sharp sand. The surface to be finished with a ½-inch
layer of Portland cement and granite chippings to pass a ¼-inch mesh, mixed in equal
proportions, or of good flags 3 inches thick with cement joints. The floor should be
laid to proper falls, and be drained by means of a suitable channel to a gully, over
which, if practicable, a draw-off tap should be fixed, the gully being properly dished
and placed outside the bakehouse.
Yards.—Any yard or passage-way adjoining the entrance of the bakehouse to be
paved with cement or other hard, durable, and impervious material at least 3 inches
thick, and formed to fall towards a properly trapped drain inlet outside.
Lighting.—All areas provided for the purpose of admitting light to be, if
necessary, lined with white glazed tiles, bricks, or opalite, with splayed bottom for
the purpose of cleansing, and fitted with pavement lights over the lighting area.
To provide and fix hopper lights of an approved pattern above the pavement lights
in the lighting area, and to make all the requisite alterations to the ceiling to permit
of the proper working of the hopper lights. Permission to construct hopper lights in
the street or passage must be obtained from the Council.
All artificial lights are to be arranged in such a manner as will assist the ventilation
of the bakehouse, as well as to enable any products of combustion to be drawn away.
Ventilation.—Fresh air is to be provided by means of three air inlets on the
"Tobin" tube system, each of a sectional area as will be sufficient, and which size
will be decided on the cubic contents of the bakehouse, the number of hands
