The attachments of each shaft rope. 4.  The attachments on any shaft conveyance or counterweight. 5.  Any shaft conveyance, counterweight and work platform. 6.  The hoist parts, brakes, clutch, brake-clutch interlocks and depth indicators. 7.  Any hoisting equipment being used for shaft sinking. 8.  Any auxiliary brake operating weights, to assure their freedom of movement and holding capacity. O. Reg. 68/96, s. 8 (3); O. Reg. 236/99, s. 10 (1). (2.2) If the parts listed in subsection (2.1) were not examined during the week before they are to be used, the examination shall be done immediately before they are used. O. Reg. 68/96, s. 8 (3). (2.3) An examination of the clutch and brake-clutch interlocks under subsection (2.1) shall include an operational check to ensure their performance. O. Reg. 236/99, s. 10 (2). (3) At least once every three months, the safety catches and mechanisms of the cage or other shaft conveyance shall be tested and such tests shall consist of releasing the empty conveyance suddenly in some suitable manner from rest, so that the safety catches and mechanisms have the opportunity to grip the guides and, where the safety catches and mechanisms do not act satisfactorily, the cage or other shaft conveyance shall not be used for lowering or raising workers until the safety catches and mechanisms have been repaired and tested and shown to act satisfactorily. O. Reg. 69/23, s. 32 (2). (4) Hoisting ropes in use on a drum hoist shall be cleaned when necessary and shall be dressed with lubricant at least once each month so as to maintain a good coating and a record of the cleaning and dressing shall be entered in the Hoisting Machinery Record Book and the entry shall be dated and signed by the supervisor in charge of the work. R.R.O. 1990, Reg. 854, s. 248 (4). (5) Revoked: O. Reg. 779/94, s. 11. (6) The portion of the hoisting rope and tail rope that is within a wedge attachment of a friction hoist shall be examined at least once after every 18 months of service and shall be cut off when an examination reveals that, (a)  there are one or more broken wires; (b)  there is advanced corrosion; (c)  there is excessive pitting; or (d)  there is excessive deformation of one or more wires. O. Reg. 296/11, s. 19 (2). (6.1) The portion of the hoisting rope and tail rope that is within a socket attachment of a friction hoist shall be cut off, (a)  after 24 months of service, in the case of tail rope within a resin socket attachment; (b)  after 18 months of service, in all other cases. O. Reg. 296/11, s. 19 (2). (7) An examination shall be made using the appropriate non-destructive test or tests to determine that the following parts are in sound condition before the parts are first used and at a regular frequency at least equal to that recommended by a person certified in accordance with section 1.1 or by an engineer: 1.  The mine hoist shafting, brake pins and linkages. 2.  Structural parts, attachment pins and draw bars of a shaft conveyance and counterweight. O. Reg. 187/19, s. 18; O. Reg. 373/22, s. 20. (7.1) Revoked: O. Reg. 187/19, s. 18. (8) Drawings of the parts to be examined under subsection (7) shall be made available, upon request, to the person performing the examination.
