Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-155 - Safety standards for construction work › Part P - STEEL ERECTION › Section 296-155-704 - Hoisting and rigging

Current through Register Vol. 24-14, July 15, 2024
(1) All the
				applicable provisions of Part L of this chapter apply to hoisting and rigging
				while using a crane/derrick. All applicable provisions of Part F-1 of this
				chapter apply to material handling hoisting equipment when a crane/derrick is
				not being used.
(2) In addition,
				subsections (3) through (5) of this section apply regarding the hazards
				associated with hoisting and rigging.
(3)
General.
(a) Crane preshift visual inspection.
(i) Cranes being used in steel erection
				activities must be visually inspected prior to each shift by a competent
				person. The inspection must include observation for deficiencies during
				operation and, as a minimum, must include:
* All control mechanisms for maladjustments;
* Control and drive mechanism for excessive wear of
				  components and contamination by lubricants, water or other foreign
				  matter;
* Safety devices, including boom angle indicators, boom
				  stops, boom kick out devices, anti-two block devices, and load moment
				  indicators where required;
* Air, hydraulic, and other pressurized lines for
				  deterioration or leakage, particularly those which flex in normal
				  operation;
* Hooks and latches for deformation, chemical damage, cracks,
				  or wear;
* Wire rope reeving for compliance with hoisting equipment
				  manufacturer's specifications;
* Electrical apparatus for malfunctioning, signs of excessive
				  deterioration, dirt, or moisture accumulation;
* Hydraulic system for proper fluid level;
* Tires for proper inflation and condition;
* Ground conditions around the hoisting equipment for proper
				  support, including ground settling under and around outriggers, ground water
				  accumulation, or similar conditions;
* The hoisting equipment for level position; and
* The hoisting equipment for level position after each move
				  and setup.
(ii) If any
				deficiency is identified, an immediate determination must be made by the
				competent person if the deficiency constitutes a hazard.
(iii) If the deficiency constitutes a hazard,
				you must remove the hoisting equipment from service until the deficiency has
				been corrected.
(iv) The operator
				is responsible for those operations under their direct control. Whenever there
				is any doubt as to safety, the operator must have the authority to stop and
				refuse to handle loads until safety has been assured.
Washington Administrative Code › Title 296 - Labor and Industries, Department of › Chapter 296-155 - Safety standards for construction work › Part P - STEEL ERECTION › Section 296-155-706 - Structural steel assembly

Current through Register Vol. 24-14, July 15, 2024
(1) You
				must maintain structural stability at all times during the erection process.
Note:
Federal Highway Administration (FHWA) regulations
						  incorporate by reference a number of standards, policies, and standard
						  specifications published by the American Association of State Highway and
						  Transportation Officials (AASHTO) and other organizations. (See
						  23 C.F.R.
						  625.4.) Many of these incorporated provisions
						  may be relevant to maintaining structural stability during the erection
						  process. For instance, as of May 17, 2010, in many cases FHWA requires a
						  registered engineer to prepare and seal working drawings for falsework used in
						  highway bridge construction. (See
AASHTO Specifications for Highway
						  Bridges, Div. II, Sec. 3.2.1, 15th edition, 1992,
which FHWA
						  incorporates by reference in
						  23 C.F.R.
						  625.4.) FHWA also encourages compliance with
						  AASHTO Specifications that the FHWA regulations do not currently incorporate by
						  reference. (See
http://www.fhwa.dot.gov/bridge/lrfd/index.htm
.)
* Make sure that multistory structures have the
				  following:
- Permanent floors installed as the erection of structural
				  members progress;
- No more than 8 stories between the erection floor and the
				  upper-most permanent floor; and
- No more than 4 floors or 48 feet (14.6 m), whichever is
				  less, of unfinished bolting or welding above the foundation or uppermost
				  permanent secured floor.
Exception:
The above applies except where the structural integrity
						  is maintained as a result of design.
(2)
Walking/working surfaces.
(a)
				Shear connectors and other similar devices.
(i) Shear connectors, reinforcing bars,
				deformed anchors or threaded studs must not be attached to the top flanges of
				beams, joists or beam attachments so they project vertically from or
				horizontally across the top flange of the member until after the metal decking,
				or other walking/working surface has been installed. This becomes a tripping
				hazard. Examples of shear connectors are headed steel studs, steel bars or
				steel lugs.
(ii) Installation of
				shear connectors on composite floors. When shear connectors are used in
				construction of composite floors, roofs and bridge decks, employees must lay
				out and install the shear connectors after the metal decking has been
				installed, using the metal decking as a working platform.

Current through Register Vol. 24-14, July 15, 2024
(1)
General requirements for erection stability.
(a) You must anchor all columns by a minimum
				of 4 anchor rods (anchor bolts).
(b) Each column anchor rod (anchor bolt)
				assembly, including the column-to-base plate weld and the column foundation,
				must be designed to resist a minimum eccentric gravity load of 300 pounds
				(136.2 kg) located 18 inches (.46 m) from the extreme outer face of the column
				in each direction at the top of the column shaft.
(c) You must set columns on level finished
				floors, pregrouted leveling plates, leveling nuts, or shim packs which are
				adequate to transfer the construction loads.
(d) All columns must be evaluated by a
				competent person to determine whether guying or bracing is needed; if guying or
				bracing is needed, you must install it.

(1)
General.
(a) During the final
				placing of solid web structural members, you must not release the load from the
				hoisting line until the members are secured with at least two bolts per
				connection. These bolts must be of the same size and strength as shown in the
				erection drawings, drawn up wrench-tight or the equivalent as specified by the
				project structural engineer of record.
Exception:
See subsection (2) of this section.
(b)
				A competent person must determine if more than two bolts are necessary to
				ensure the stability of cantilevered members; if additional bolts are needed,
				you must install them.

				any structural steel framework unless such framework is safely bolted, welded
				or otherwise adequately secured.
(5) In girt and eave strut-to-frame
				connections, when girts or eave struts share common connection holes, at least
				one bolt with its wrench-tight nut must remain connected to the first member
				unless a manufacturer-supplied, field-attached seat or similar connection
				device is present to secure the first member so that the girt or eave strut is
				always secured against displacement.
(6) Both ends of all steel joists or
				cold-formed joists must be fully bolted and/or welded to the support structure
				before:
(a) Releasing the hoisting
				cables;
(b) Allowing an employee on
				the joists; or
(c) Allowing any
				construction loads on the joists.
