Operation Requirements of Cranes and Derricks
Requirements for the operation of cranes and derricks include:
-The employer shall:
a. Follow manufacturer procedures for operation of the equipment including the use of attachments. Where procedures for operation are unavailable, the employer shall comply with 1616.1. (Note: while operating equipment, devices such as cell phones shall not be used for any other activities (texting, talking, etc.) other than signaling).
b. Ensure loads are rigged by a qualified person or by a trainee under the qualified person’s direct visual supervision.
c. Where traveling with a load, the employer shall ensure that a competent person supervises the operation.
d. Ensure operators do not suddenly accelerate or decelerate a moving load. 4999(f).
e. Not allow the load, boom, or other parts of the equipment to contact any obstruction during lifting operations. 1616.1(o).
-Whenever there is a concern as to safety, the operator shall have the authority to stop and refuse to handle loads until a qualified person has determined that safety has been assured
-Employers must control work areas and protect employees in the hazardous areas. Requirements include:
a. Communication among operators and signal persons shall be followed as per 1616.3 and 4993.1.
b. Where any part of a crane or derrick is within the load radius of another crane or derrick, employers must establish a system to coordinate the operations.
c. Prevent employees from entering the hazardous areas by providing employee training, setting up barriers, etc. as per 4993.1.
Before an employee goes to a location in the hazard area that is out of view of the operator, the operator must be informed by the employee. 4993.1(a)(3)(A).
-Operations shall be conducted and the job controlled in a manner that will avoid exposure of employees to the hazard of overhead loads. Wherever loads must be passed directly over workers, occupied work spaces, or occupied passageways, safety type hooks or equivalent means of preventing the loads from becoming disengaged shall be used. All requirements under 1616.4 shall also be met
-Boom free fall is prohibited in each of the circumstances mentioned in 1616.5. Controlled load lowering is required and free fall of the load line hoist is prohibited in each of the circumstances mentioned in 1616.5(d)
-The use of equipment to hoist employees is prohibited except where the employer demonstrates that the erection, use, and dismantling of conventional means of reaching the work area would be more hazardous, or is not possible because of the project’s structural design or worksite conditions.
-Hoisting of personnel using cranes is possible only when all of the requirements of 1616.6 are met (Note: the requirements of 1616.6 are supplemental and apply when one or more employees are hoisted.)
-Supplemental requirements for Multiple-Crane/Derrick Lifts are provided in 1616.7. Before beginning a crane/derrick operation in which multiple crane/derrick will be supporting the load, the operation shall be planned as per 1616.7(a) and directed by a qualified person
