A certified rigger is a person who has been trained and certified to handle and move loads. The level of certification depends upon the individual’s training, knowledge, skill base, and ability to perform functions related to the selection, inspection, and proper use of rigging equipment.
This person may be qualified in a craft or trade and carry an occupational title such as iron worker, electrician, carpenter, millwright, mechanic, laborer, mason, longshoreman, lineman, pipe fitter, boilermaker, and the like. (The persons described in the categories above will be referred to as rigger even though they carry another occupational title.)
CERTIFIED RIGGER LEVEL I
ARAMCO identified the following job duties for Rigger Level I certification. A Certified Rigger Level I can perform simple, repetitive rigging tasks when the load weight, center of gravity, the rigging, and rigging configuration are provided or known by the rigger through experience or on-the-job training prior to the rigging activities. Specifically, Level I Riggers should be able to demonstrate or have knowledge of how to:
· Inspect rigging before use
· Identify and attach rigging with basic knowledge of hitch configurations, capacities, and basic knots
· Recognize associated hazards
· Signal operations
· Use various types of rigging equipment and basic hitches and their applications
CERTIFIED RIGGER LEVEL II
In addition to knowing and demonstrating Rigger Level I knowledge and skills, a Certified Rigger Level II can select rigging components and procedures based on rigging capacity. A Level II Rigger can perform the following rigging tasks unsupervised:
· Estimate load weight and center of gravity
· Identify lift points
· Determine and select rigging based on loading
· Perform pre-use inspection of rigging and lift points
· Identify and attach rigging with knowledge of hitch configurations and load angle factors, rigging capacities, and load integrity
· Understand load dynamics and associated hazards
As applicable, Level II Riggers will also have a working knowledge of hoisting equipment, winches, jacks, industrial rollers, and similar equipment.
