FACTORIES ACT (NORTHERN IRELAND) 1965 - SECT 67

Humid factories.

67.(1) The occupier of every humid factory shall, on or before the first
occasion on which artificial humidity is produced at that factory, give notice
thereof in writing to the chief inspector.

(2) The following provisions of this section shall have effect with respect to
every humid factory with respect to which regulations under this Act
concerning humidity are not for the time being in force.

(3) There shall be provided and maintained in every room in which artificial
humidity is produced two hygrometers conforming to such conditions as regards
construction and maintainance as may be prescribed, and

(a)one of the hygrometers shall be fixed in the centre and the other at the
side of the room, or in such other position as may be directed or sanctioned
by an inspector, so as to be plainly visible to the persons employed;

(b)a copy of the table of humidity set out in Schedule 1, or such other table
as may be substituted therefor by regulations of the Ministry, shall be kept
hung up near each hygrometer;

(c)the occupier or other person authorised for the purpose shall read the
hygrometers between ten and eleven o'clock in the morning on every day on
which any persons are employed in the room in the morning and between three
and four o'clock in the afternoon on every day on which any persons are
employed in the room in the afternoon, and when persons are employed before
six o'clock in the morning or after eight o'clock in the evening, at such
other times as may be directed by the chief inspector, and shall enter the
readings on a record, which shall be provided for each hygrometer in the
prescribed form;

(d)the forms on which the readings of each hygrometer are recorded shall be
kept hung up near the hygrometer, and when filled up shall be preserved at the
factory for reference, and the entries recorded in the form shall be prima
facie evidence of the humidity of the atmosphere and temperature in the
factory.

(4) There shall be no artificial humidification in any room at any time when
the reading of the wet bulb thermometer exceeds seventy-two and a half
degrees, or, in the case of a room in which the spinning of cotton or the
spinning of merino or cashmere by the French or dry process or the spinning or
combing of wool by that process is carried on, eighty degrees.

(5) There shall be no artificial humidification in any room at any time when
the difference between the readings of the dry and wet bulb thermometers is
less than that indicated in the table of humidity.

(6) Any water which is liable to cause injury to the health of the person
employed, or to yield effluvia, shall not be used for artificial
humidification, and for the purposes of this subsection any water which
absorbs from acid solution of permanganate of potash in four hours at sixty
degrees more than half a grain of oxygen per gallon of water shall be deemed
to be liable to cause injury to the health of the persons employed.

(7) The chief inspector may direct in writing, in the case of any factory or
any room in a factory, that only one hygrometer, fixed in such position as may
be directed by an inspector, need be provided instead of two hygrometers fixed
as mentioned in subsection (3)(a).

(8) Where in respect of any room notice has been given in the prescribed
manner to the chief inspector that it is intended that the humidity of the
atmosphere should never be greater than will maintain a difference of at least
four degrees between the readings of the dry and wet bulb thermometers, the
provisions of subsection (3)(c) and (d) shall not apply as respects that room
so long as at least that difference is maintained and a copy of the said
notice is kept posted in the room.
