Factories Act, 1948
36. Precautions against dangerous fumes,
gases, etc.
(1) No person shall be required or allowed to enter any chamber,
tank, vat, pit, pipe, flue or other confined space in any factory in which any
gas, fume, vapor or dust is likely to be present to such an extent as to
involve risk to persons being overcome thereby, unless it is provided with a
manhole of adequate size or other effective means of egress.
(2) No person shall be required or allowed to enter any confined
space as is referred to in sub-section (1), until all practicable measures have
been taken to remove any gas, fume, vapor or dust, which may be present so as
to bring its level within the permissible limits and to prevent any ingress of
such gas, fume, vapor or dust and unless-
(a) a certificate in writing has been given by
a competent person, based on a test carried out by himself that the space is
reasonably free from dangerous gas, fume, vapor or dust; or
(b) such person is wearing suitable breathing
apparatus and a belt securely attached to a rope the free end of which is held
by a person outside the confined space.]
