Critical Lift Procedure
A critical lift procedure is a documented, preplanned method for executing a lift that meets jurisdictional criteria, such as WorkSafeBC's OHS Regulation Part 14. It includes a written lift plan or code of practice, specifying load weight, rigging, equipment configuration, travel path, communication, and stop/hold points. The plan must be available at the worksite and communicated in a pre-job meeting before the lift begins.
On a manufacturing or shop floor, the critical lift procedure controls non-routine or high-consequence lifts by defining load, rigging, equipment configuration, travel path, communication method, signaller position, wind or travel limits, and stop/hold points. For Canadian compliance, WorkSafeBC requires a written lift plan for every critical lift and a documented pre-job meeting, repeated if people or equipment change. WorkSafeNB's code-of-practice model similarly requires rigging details, wind speed limitations, maximum hoist and travel speeds, load distribution, signalling, and an effective communication system. The lift is classified first; if it meets a critical-lift trigger, normal lifting rules are insufficient, and a written plan is mandatory. The competent supervisor reviews load weight, center of gravity, crane/hoist configuration, sling angles, radius, obstructions, and communications before the lift. The team holds a pre-job meeting immediately before hoisting, confirms roles, and documents that briefing. The lift is executed only under the plan, with signallers and communication controls in place, and the job stopped if conditions change.
What makes a lift 'critical' under WorkSafeBC?
It includes mobile-crane lifts above 90% of rated capacity at a load radius greater than 50% of maximum permitted radius, tandem lifts above 75% on any one unit, lifts involving more than two powered units, personnel lifts, changing-center-of-gravity loads, changing sling-leg length, lifts over energized high-voltage conductors, and submerged loads.
Is a critical lift procedure the same as a lift plan?
In Canadian practice, the procedure is the lift plan/code of practice required to control the critical lift; WorkSafeBC expressly requires a written lift plan, and WorkSafeNB describes a code of practice containing the same operational controls.
Who needs to know the procedure?
Everyone involved in the critical lift must be briefed before the lift, and communication must be effective and maintained throughout the operation.
