(5) If belting is fitted in way of a hoist position, such belting shall be cut back sufficiently to allow the hoist to be placed as close as is practicable to the ship's side. (Enacted 1995) Cap 369AU s 19 Control of hoists (1) A hoist shall be fitted with an automatic safety device in order to cut off the power supply when the ladder comes against any stop so as to avoid overstressing the falls or any other part of the hoist: Provided that, in the case of a hoist operated by pneumatic power, the safety cut-out device may be omitted if the maximum torque available from the air motor cannot result in overstressing of the falls or other parts of the hoist. (2) All hoist controls shall incorporate an emergency stop to cut off the power supply and an emergency stop switch within easy reach of the person carried by means of which he may cut off the power. (3) The winch controls for a hoist shall- (a) be clearly and durably marked to indicate- (i) in the case of a hoist installed before 1 January 1994, "Hoist", "Stop" and "Lower"; (ii) in the case of a hoist installed on or after 1 January 1994, "Lift", "Stop" and "Lower";(b) correspond to the manner in which the hoist operates; and (c) automatically return to the "Stop" position when released. (Enacted 1995) Cap 369AU s 20 Operation of hoists Expanded Cross Reference: 6, 7, 8, 9, 10, 11 (1) The master shall ensure that rigging and use of the hoist shall be supervised by a responsible officer of the ship. (2) Any person engaged in rigging and operating a hoist shall be instructed in the rigging and operating procedures as contained in the approved manual and the equipment shall be tested prior to the embarkation or disembarkation of any person. (3) The master shall ensure that a pilot ladder complying with sections 6 to 11 is- <* Note - Exp. X-Ref.: Sections 6, 7, 8, 9, 10, 11 *> |
