According to ASME B30.27-2014, here are the responsibilities of each of the players:

Pump Owner: The pump owner must ensure that the equipment meets all of the requirements. He or she must provide technical information, operating instructions, maintenance information, warning labels, and other pertinent documentation. The standard also spells out necessary communication between the owner and the site supervisor, pour supervisor, and others.

Pump or Belt Operator: Operators are assigned a specific list of responsibilities but are not responsible for conditions outside their direct control. The standard emphasizes the importance of communicating with pour supervisors regarding potential jobsite hazards.

Material Placement System Users: When those in this role are not the pump owner, there are rules pertaining to training, personnel qualifications, and placement preparation/procedures.

Site Supervisors and Pour Supervisors: The supervisor must review site-specific regulations and ensure that those who will be performing the work are qualified. Key supervisory responsibilities include coordinating material placement system operations with other jobsite activities and taking steps, as outlined in the standard, to prepare the construction area and address site conditions and potential hazards.

Concrete Supplier: Both the ready-mixed concrete producer and drivers are responsible for delivering material according to the specifications and for providing training in all safety regulations.

Placing Crew: The crew must follow all safety regulations and carry out their assigned duties according to the standard.

Many personnel will be present on the jobsite near a concrete pour who are not specifically included in the new standard. These workers must be given due consideration when making real-time, on-the-ground safety decisions.
