Operating large machinery, such as cranes, is dangerous work. There are specific circumstances under which signal persons – or spotters – with special training are required to ensure that operations run smoothly and are as safe as possible. Effective communication between a signal person and a crane operator is required when the point of crane operation is not in full view of the operator, when the operator's view is obstructed in the direction the equipment is traveling, and when either the operator or the person handling the load determines that a signal person is needed for safety concerns. This course will provide you with an understanding of the qualification requirements for signal persons and considerations for communication between signal persons and crane operators. In this course, you will learn when a signal person is required, what hand signals they should use, and how to ensure safe communication between the signal person, the person handling the load, and the crane operator. This will allow the operation of mobile cranes in accordance with the Occupational Safety and Health Administration (OSHA)'s 'Signal Person Qualification' standards at part 29 Code of Federal Regulations (CFR) 1926.1428, and supporting information at 29 CFR parts 1419 through 1422.
