WORKSAFEBC BULLETIN – Tandem LIfts from Barges to Land
19 September 2017

A forklift and a log loader were unloading a bundle of metal culverts off a barge in a tandem lift. The log loader was pulling on a chain that was wrapped around the bundle of culverts when the chain snapped. A piece of the broken chain struck and seriously injured a worker on the ground who was helping with the unloading operation.

Unloading long and heavy loads, such as culvert bundles or modular bridges, from a barge onto land is a frequent activity aong the west coast of British Columbia. Unloading usually involves two pieces of mobile equipment (a tandem lift).

Most of the time there are at least two independent employers involved — the shipping service on the barge and the receiving client on the land. The two companies may be unfamiliar with each other's operational plans or priorities so it's important for the companies to communicate with each other about the lift. A lack of coordination between the companies can increase the risk of an incident occurring.

What are the hazards?

There are a number of things that can go wrong when doing a tandem lift from barge to land:

  • Loss of stability or control of the equipment involved in the lift
  • Rigging failure
  • Loss of the load
  • Workers on the ground getting in the bight of the equipment and the load

Those at risk include equipment operators, workers on the barge, and workers on the landing.

How to prevent similar incidents

Learn more about:
→ determining load weights,
→ communicating with hand signals,
→ inspecting slings and hardware,
→ making basic lift plans and more.

For more details and information, see Rigger Training & Certification.

  • Load — Know the weight and distribrution of the load to be lifted
  • Equipment — Ensure that the equipment used is capable of safely performing the lift.
  • Rigging slings — Determine the working load limit of the rigging sling and ensure it is not exceeded during the lift.
  • Lift plan — Prepare a written lift plan and instruct workers in the plan. The supervisors for each of the employers involved must ensure that all hazards are identified and risks are communicated to everyone involved in the lift. Make sure the plan is available at the worksite during the lift.
  • Communication — Establish and maintain effective communication between everyone involved in the lift.

Regulation requirements

The prevention requirements listed in this bulletin are specified inthe following sections of the Occupation al Health and Safety Regulation:

  • Load — 14.36 and 14.42(3)(e)
  • Equipment — 4.3(1)
  • Rigging slings — 4.3(1) and 15.30
  • Lift plan — 14.42(2) and 14.43
  • Communication — 14.42(5) to (7)

Safety Notice 170012

Two-Blocking Damage Prevention
25 March 2014

We have noticed a dangerous situation occurring amongst folding boom crane owners and operators. Folding booms equipped with winches require a device to prevent two blocking.

Wording of OHS regulations references that the requirement for anti-two block devices was repealed in 2006. This change only applies to the wording.

BC OHS regulations require articulating (folding) boom cranes to adhere to ANSI / ASME B30.22-2005 which states that folding boom cranes equipped with a winch must be equipped with a feature to prevent damage from two-blocking.

This hazard alert from WorkSafe BC June 2012 describes the dangers to workers and equipment from two blocking: Hazard Alert: Worker struck by load after articulating boom crane "two-blocks"
