Section 408.42604. Definitions; A to C.

(1) "Anchored bridging" means that the steel joist bridging is connected to a bridging terminus point.

(2)   "Bolted diagonal bridging" means diagonal bridging that is bolted to a steel joist or joists.

(3)   "Bridging clip" means a device that is attached to the steel joist to allow the bolting of the bridging to the steel joist.

(4)    "Bridging terminus point" means a wall, a beam, tandem joists, with all bridging installed and a horizontal truss in the plane of the top chord, or other element at an end or intermediate point or points of a line of bridging that provides an anchor point for the steel joist bridging.

(5)   "Choker" means a wire rope or synthetic fiber rigging assembly that is used to attach a load to a hoisting device.

(6)    "Cold forming" means the process of using press brakes, rolls, or other methods to shape steel into desired cross sections at room temperature.

(7)    "Column" means a load-carrying vertical  member  that   is  part  of the primary skeletal framing system. Columns do not include posts.

(8)    "Competent person" means a person who is experienced and capable of identifying an existing or potential hazard in surroundings,   or  under  working conditions, that are hazardous or dangerous to an employee and who has the authority and knowledge to take prompt corrective   measures  to eliminate the hazards.

(9)   "Connector" means an employee who, working with hoisting equipment, is placing and connecting structural members or components.

(10)   "Constructibility" means the ability to erect structural steel members in accordance with these rules without having to alter the overall structural design.

(11)   "Construction load, for joist erection," means any load other  than the weight of the employee or employees, the joists, and the bridging bundle.

(12)   "Controlled decking zone (CDZ)" means an  area  in   which   certain work, for example, initial installation and placement of metal  decking,  may take place without

the use of guardrail systems,  personal      fall      arrest systems, fall restraint systems, or safety net systems and in which access to the zone is controlled.

(13)    "Controlled load lowering" means lowering a load by means of a mechanical hoist drum device that allows a hoisted load to be  lowered with maximum control using the gear train or hydraulic components  of  the  hoist mechanism. Controlled load lowering requires the use of the hoist drive motor, rather than the load hoist brake, to lower the load.

(14)     "Controlling contractor" means a prime contractor, general contractor, construction manager, or any  other   legal  entity  that  has the  overall responsibility for the construction of  the   project--its planning, quality, and completion.

(15)   "Critical lift" means a lift that exceeds 75% of the rated  capacity of the crane or derrick or that requires the use of more than 1 crane or derrick.
