103.1 (1) In this section, “move” includes raise and lower; (“déplacer”) “multi-tiered load” means two or three individually rigged structural steel pieces that are, (a) suspended so that they remain horizontal, (b) aligned vertically, and (c) moved simultaneously by a crane; (“charge superposée”) “multi-tiered load hoisting operation” means the moving of one or more multi-tiered loads by one crane at a project; (“opération de levage d’une charge superposée”) “procedures” means the procedures prepared under subsection (7). (“procédures”) O. Reg. 627/05, s. 3. (2) A multi-tiered load, (a) shall not contain structural steel pieces that are bundled together; (b) shall not contain more than three structural steel pieces; (c) shall not use one structural steel piece to support another; (d) shall have each structural steel piece independently slung back to the main load hook or master link; (e) shall be lowered only by a crane using power-controlled lowering. O. Reg. 627/05, s. 3. (3) A crane shall be used to move only one multi-tiered load at a time. O. Reg. 627/05, s. 3. (4) A crane shall not be used for a multi-tiered load if it is contrary to the crane manufacturer’s specifications or limitations to do so. O. Reg. 627/05, s. 3. (5) No worker shall be in an area where a multi-tiered load hoisting operation is taking place unless he or she is directly engaged in the operation. O. Reg. 627/05, s. 3. (6) Before a multi-tiered load hoisting operation is begun at a project, written procedures to ensure the safety of workers engaged in the operation shall be developed and implemented. O. Reg. 627/05, s. 3. (7) The procedures shall be prepared by an engineer in accordance with good engineering practice and shall, (a) include design drawings that illustrate the arrangement and dimensions of the structural steel pieces, the assembly of rigging components and devices, and all attachment points; (b) identify the crane and its rated load-carrying capacity, and identify and specify its limitations and restrictions, if any; (c) describe the method of determining the weight of the structural steel pieces; (d) specify the maximum load per lift and the maximum reach of the crane per lift; (e) identify all factors that could affect the safety of the multi-tiered load hoisting operation, such as wind speed, weather conditions, potential overlapping of cranes and other restrictions; (f) state the measures to be taken to control and secure multi-tiered loads while they are being moved; (g) specify any circumstances that would require additional work, including inspections, to be performed by an engineer to ensure the safety of any worker engaged in the multi-tiered load hoisting operation; and (h) identify all critical parts of the rigging and of the rigged structural steel pieces that are to be inspected before each lift, and set out the inspection criteria to be followed. O. Reg. 627/05, s. 3; O. Reg. 142/17, s. 14; O. Reg. 375/22, s. 5. (8) The employer responsible for a multi-tiered load hoisting operation shall, (a) create a document that identifies the workers engaged in the multi-tiered load hoisting operation by name and job title and states their respective duties; (b) ensure that, before the multi-tiered load hoisting operation is begun, a copy of the procedures is provided to and reviewed with each worker engaged in the operation; (c) ensure that the procedures are implemented, and are followed throughout the multi-tiered load hoisting operation; (d) ensure that any deviations from the procedures are approved by an engineer, in writing, before any multi-tiered load is moved; and (e) unless the engineer who prepared the procedures specifies otherwise, appoint a competent worker to ensure that the procedures, including the inspections described in clause (7) (h), are followed before any multi-tiered load is moved. O. Reg. 627/05, s. 3; O. Reg. 375/22, s. 5. (9) The employer responsible for a multi-tiered load hoisting operation shall keep a copy of the following available for inspection at the project until the operation is completed: 1. The procedures. 2. The document described in clause (8) (a). 3. Any approvals given under clause (8) (d). O. Reg. 627/05, s. 3. (10) Before the first multi-tiered load hoisting operation is started at a project, the constructor shall give notice to the Ministry office located nearest the project, in person, by telephone, by fax or by electronic means. O. Reg. 627/05, s. 3.
