Acts, 1881 and 1892.{1}
[4th August 1906]
PART I

ALKALI, &C. WORKS REGULATION ACT 1906 - SECT 1

1.(1) Every alkali work shall be carried on in such manner as to
secure the condensation, to the satisfaction of the chief inspector,
of the muriatic acid gas evolved in such work, to the extent of
ninety-five per centum, and to such an extent that in each cubic
foot of air, smoke, or chimney gases, escaping from the works into
the atmosphere, there is not contained more than one-fifth part of
a grain of muriatic acid.

[(2) The owner of any alkali work which is carried on in
contravention of this section shall be guilty of an offence.]

ALKALI, &C. WORKS REGULATION ACT 1906 - SECT 2
Prevention of discharge of noxious and offensive gas in alkali
works.

2.(1) In addition to the condensation of muriatic acid gas as
aforesaid, the owner of every alkali work shall use the best
practicable means for preventing the escape of noxious or offensive
gases by the exit flue of any apparatus used in any process
carried on in the work, and for preventing the discharge, whether
directly or indirectly, of such gases into the atmosphere, and for
rendering such gases where discharged harmless and inoffensive,
subject to the qualification that, on the basis of the amount of
acid gas per cubic foot, no objection shall be taken under this
section by an inspector to any muriatic acid gas in the air,
smoke, or gases discharged into the atmosphere by a chimney or
other final outlet where the amount of such acid gas in each cubic
foot of air, smoke, or gases so discharged does not exceed the
amount limited by the last preceding section.

[(2) If the owner of any alkali work fails, in the opinion of the
court having cognizance of the matter, to use such means, he shall

Condensation of acid gases in sulphuric acid and muriatic acid
works.

ALKALI, &C. WORKS REGULATION ACT 1906 - SECT 6

6.(1) Every sulphuric acid work as defined in paragraph (1) of the
First Schedule to this Act shall be carried on in such manner as
to secure the condensation, to the satisfaction of the chief
inspector, of the acid gases of sulphur or of sulphur and nitrogen
which are evolved in the process of the manufacture of sulphuric
acid in that work, to such an extent that the total acidity of
those gases in each cubic foot of residual gases after completion
of the process, and before admixture with air, smoke, or other
gases, does not exceed what is equivalent to four grains of
sulphuric anhydride.

(2) Every muriatic acid work as defined in paragraph (8) of the
First Schedule to this Act shall be carried on in such manner as
to secure the condensation to the satisfaction of the chief
inspector of the muriatic acid gas evolved in such work, to such
extent that in each cubic foot of air, smoke, or chimney gases
escaping from the work into the atmosphere there is not contained
more than one-fifth part of a grain of muriatic acid.

[(3) The owner of any sulphuric acid work or of any muriatic acid
work which is carried on in contravention of this section shall be
guilty of an offence.]

ALKALI, &C. WORKS REGULATION ACT 1906 - SECT 7
Prevention of discharge of noxious or offensive gas in scheduled
works.

7.(1) The owner of any work specified in the First Schedule to
this Act (hereinafter referred to as a scheduled work) shall use
the best practicable means for preventing the escape of noxious or
offensive gases by the exit flue of any apparatus used in any
process carried on in the work, and for preventing the discharge,
whether directly or indirectly, of such gases into the atmosphere,
and for rendering such gases where discharged harmless and
inoffensive, subject to the qualification that, on the basis of the
amount of acid gas per cubic foot, no objection shall be taken
under this section by an inspector

(a)To any muriatic acid gas in the air, smoke, or gases discharged
into the atmosphere by a chimney or other final outlet, where the
amount of such acid gas in each cubic foot of air, smoke, or
gases so discharged does not exceed the amount limited by the last
preceding section:

(b)To any acid gases in the air, smoke, or gases discharged into
the atmosphere by a chimney or other final outlet receiving the
residual gases from any process for the concentration or distillation
of sulphuric acid, where the total acidity of such acid gases
(including those from the combustion of coal) in each cubic foot of
air, smoke, or gases so discharged does not exceed what is
equivalent to one grain and a half of sulphuric anhydride.

[(2) If the owner of any such work fails, in the opinion of the
court having cognizance of the matter, to use such means, he shall
be guilty of an offence.]
