232. (1) A cage, being used to transport persons, shall, (a)  where it is supported by only a single rope or attachment point have the safety catches and mechanisms prescribed in subsection (6); (b)  except on any side which has a door, be enclosed by sheet steel at least three millimetres thick; (c)  have ventilation, adequate for the persons being transported; (d)  have a hood of steel plate, at least five millimetres thick; (e)  have a door or doors as prescribed in subsection (2); (f)  have an internal height greater than 2.1 metres; (g)  have a clearance at the door that is greater than 1.8 metres; and (h)  have where practical, an exit for the persons in the roof which can be opened from inside or outside the cage.  R.R.O. 1990, Reg. 854, s. 232 (1). (2) The door or doors on a cage shall, (a)  be at least 1.5 metres high; (b)  be mounted and arranged so they cannot be opened outward from the cage; (c)  have devices for positive latching in the closed position; (d)  be of solid materials, except for a viewing window; (e)  be so arranged that they may be closed at all times that persons or materials, except rolling stock, are being transported in the cage; (f)  be mounted so as to provide only enough clearance at the floor to permit free closing or opening; and (g)  be of adequate strength to withstand normal shock loads.  R.R.O. 1990, Reg. 854, s. 232 (2). (3) A skip used to transport workers in a shaft shall meet the following requirements unless it is being used to transport workers for shaft inspection or shaft maintenance or unless it is being used in an emergency: 1.  The skip must have the safety catches and mechanisms required by subsection (6) if the skip is supported by only a single rope or attachment point. 2.  The skip must provide an enclosure at least 1.07 metres high for the persons being transported. 3.  The skip must have ventilation that is adequate for the persons being transported. 4.  The skip must have a suitable floor that is adequately fastened. 5.  The skip must have a means for safe entry and exit.  O. Reg. 571/92, s. 19. (3.1) For the purposes of subsection (3), a skip is considered to be being used in an emergency if it is being used to hoist injured people, to evacuate people, to fight fire or to enable people to perform emergency repair work necessary to maintain the mine or the mine dewatering system, electrical system or ventilation system.  O. Reg. 571/92, s. 19. (4) The openings between a shaft and a skip box over which persons must pass to enter or leave a skip shall be closed off sufficiently to prevent a person from falling through the opening.  R.R.O. 1990, Reg. 854, s. 232 (4). (5) The shaft signal pull cord shall be located in a convenient place for the skip tender.  R.R.O. 1990, Reg. 854, s. 232 (5). (6) Safety catches and mechanisms on a cage or skip shall, (a)  be of a type and design that meets good engineering practice; (b)  stop and hold a cage or skip transporting persons should the supporting rope or attachment break; and (c)  be subjected to the tests prescribed in subsection (7) and successfully pass the free fall test prescribed in subsection (8), (i)  prior to the cage or skip first being used to transport persons, and (ii)  prior to the cage or skip first being used after repairs to correct distortion of the safety catches and mechanisms.  R.R.O. 1990, Reg. 854, s. 232 (6); O. Reg. 272/97, s. 42 (1). (7) Free fall tests shall be performed under the following conditions: 1.  The cage or skip must carry a weight equal to its maximum permitted load of persons and any material permitted to be carried at the same time. 2.  The cage or skip must travel at a speed equal to, i.  the normal hoisting speed when transporting persons, or ii.  the speed attained by a free fall of 1.5 metres. 3.  The guides on which the test is made must be of the same specifications as those in the shaft in which the conveyance will operate.  O. Reg. 68/96, s. 6 (1). (7.1) A free fall test shall not be performed at the speed attained by a free fall of 1.5 metres unless the design and configuration of the safety catches and mechanisms and the loading on the cage or skip have been tested at normal hoisting speed before the free fall. O. Reg. 69/23, s. 31 (1). (7.2) If a free fall test is to be performed at the speed attained by a free fall of 1.5 metres, the person performing the test shall record the rate of deceleration and the rate of change in deceleration of the cage or skip on a chart suitable for determining the deceleration of the conveyance.  O. Reg. 68/96, s. 6 (1). (8) A free fall test shall be successfully passed if, (a)  the skip or cage decelerates to a stop at an average rate that is not less than nine or greater than 20 metres per second per second. (b)  there is no damage to the safety catches and mechanisms; (c)  the safety catches and mechanisms engage the guides continuously during deceleration; and (d)  a calculation shows that the safety catches and mechanisms will stop the cage or skip when it is carrying its maximum material load. R.R.O. 1990, Reg. 854, s. 232 (8); O. Reg. 68/96, s. 6 (2); O. Reg. 69/23, s. 31 (2-4). (9) A report of a free fall test shall be made in the Hoisting Machinery Record Book for the hoist.  O. Reg. 272/97, s. 42 (2).
