It is important that workers involved with hoisting and rigging activities, and trailer safety chain requirements know both safety and operation procedures, including incorrect chain usage. Hoisting equipment should be operated only by trained personnel.
The cause of rigging accidents can often be traced to a lack of knowledge on the part of a rigger. Training programs such as the Basic Safety Training for Hoisting and Rigging and others that we offer, can provide workers with a basic knowledge of principles relating to safe hoisting and rigging practices in the construction industry.
A safe rigging operation requires the rigger to know
- the weight of the load and rigging hardware
- the capacity of the hoisting device
- the working load limit of the hoisting rope, slings, and hardware.
When the weights and capacities are known, the rigger must then determine how to lift the load so that it is stable. Training and experience enable riggers to recognize hazards that can have an impact on a hoisting operation and avoiding incorrect chain useage.
Riggers must be aware of elements that can affect hoisting safety, factors that reduce capacity, and safe practices in rigging, lifting, and landing loads. Riggers must also be familiar with the proper inspection and use of slings and other rigging hardware.
Most crane and rigging accidents can be prevented by field personnel following basic safe hoisting and rigging practices. When a crane operator is working with a rigger or a rigging crew, it is vital that the operator is aware of the all aspects of the lift and that a means of communication has been agreed upon, including what signals will be used.
The diagram below shows the many potential ways that chain can be used incorrectly and have the potential to cause a serious accident.
