Title of Rule: Longshore, stevedore and related waterfront operations, chapter 296-56 WAC.

Purpose: December of 1998, federal and state-initiated amendments were made to chapter 296-56 WAC, Safety standards for longshore, stevedore and related waterfront operations. These amendments were sent to the Occupational Safety and Health Administration (OSHA) for federal approval on February 17, 1999. We received a letter dated May 13, 1999, from OSHA indicating that there were areas in our standard that did not meet the "at-least-as-effective as" OSHA criteria. These amendments must be made to bring our requirements into compliance with the federal requirements as mandated. In addition, OSHA has made several housekeeping type amendments which are included in this proposal.

     The following are the federal-initiated proposed changes:

     (i) Except for eye splices in the ends of wires and for endless rope slings, each wire rope used in hoisting or lowering, or in bulling cargo, shall consist of one continuous piece without knot or splice.

     (4) Natural fiber rope.

     (a) The employer shall ascertain the manufacturer's ratings for the specific natural fiber rope used and have such ratings available at the terminal.      The manufacturer's ratings shall be adhered to and a minimum design safety factor of five maintained.

C=√.6(Cs2)+.4(Cm2)

Where C= the required circumference of the synthetic rope in inches, Cs= the circumference to the nearest one-quarter inch of a synthetic rope having a breaking strength not less than that of the size manila rope that would be required by subsection (4) of this section, and Cm= the circumference of manila rope in inches which would be required by subsection (4) of this section.

     (c) In making such substitution, it shall be ascertained that the inherent characteristics of the synthetic fiber are suitable for hoisting.

     (6) Removal of natural and synthetic rope from service.      Natural or synthetic rope having any of the following defects shall be removed from service:

     (d) Variations in the size or roundness of strands;

     (e) Discolorations other than stains not associated with rope damage;

     (f) Rotting; or

     (g) Distortion or other damage to attached hardware.

     (7) Thimbles.      Properly fitting thimbles shall be used where any rope is secured permanently to a ring, shackle or attachment, where practical.

     (8) Synthetic web slings.

     (a) Slings and nets or other combinations of more than one piece of synthetic webbing assembled and used as a single unit (synthetic web slings) shall not be used to hoist loads in excess of the sling's rated capacity.

     (b) Synthetic web slings shall be removed from service if they exhibit any of the following defects:

     (vi) Display of visible warning threads or markers designed to indicate excessive wear or damage.

     (c) Defective synthetic web slings removed from service shall not be returned to service unless repaired by a sling manufacturer or similar entity.      Each repaired sling shall be proof tested by the repairer to twice the slings' rated capacity prior to its return to service.      The employer shall retain a certificate of the proof test and make it available for examination.

     (d) Synthetic web slings provided by the employer shall only be used in accordance with the manufacturer's recommendations, which shall be made available upon request.

     (e) Fittings shall have a breaking strength at least equal to that of the sling to which they are attached and shall be free of sharp edges.

     (9) Chains and chain slings used for hoisting.

     (a) The employer shall adhere to the manufacturer's recommended ratings for safe working loads for the sizes of the wrought iron and alloy steel chains and chain slings used and shall have such ratings available.      When the manufacturer is unable to provide such ratings, the employer shall use the tables for chains and chain slings found in American National Safety Standard for Slings, ANSI B30.9-1971.

     (b) Proof coil steel chain, also known as common or hardware chain, and other chain not recommended by the manufacturer for slinging or hoisting shall not be used for slinging or hoisting.

     (c)(i) Sling chains, including end fastenings, shall be inspected for visible defects before each day's use and as often as necessary during use to ensure integrity of the sling.

     (ii) Thorough inspections of chains in use shall be made quarterly to detect wear, defective welds, deformation, increase in length or stretch.      The month of inspection shall be indicated on each chain by color of paint on a link or by other effective means.

     (iii) Chains shall be removed from service when maximum allowable wear, as indicated in Table C-2, is reached at any point of link.

     (iv) Chain slings shall be removed from service when stretch has increased the length of a measured section by more than five percent; when a link is bent, twisted or otherwise damaged; or when a link has a raised scarf or defective weld.

     (ii) Overhead guards shall not obstruct the operator's view, and openings in the top of the guard shall not exceed six inches (((15.2)) 15.24 cm) in one of the two directions, width or length.      Larger openings are permitted if no opening allows the smallest unit of cargo being handled to fall through the guard.

     (iii) Overhead guards shall be built so that failure of the vehicle's mast tilting mechanism will not displace the guard.

     (iv) An overhead guard, otherwise required by this paragraph, may be removed only when it would prevent a truck from entering a work space and if the operator is not exposed to low overhead obstructions in the work space.

     (v) Overhead guards shall be large enough to extend over the operator during all truck operations, including forward tilt.

     (a) Where a seated operator may come into contact with projecting overhead members, crawler-type bulk-cargo-moving vehicles that are rider operated shall be equipped with operator guards.

     (b) Guards and their attachment points shall be so designed as to be able to withstand, without excessive deflection, a load applied horizontally at the operator's shoulder level equal to the drawbar pull of the machine.

     (c) After July 26, 1999, bulk cargo-moving vehicles shall be equipped with rollover protection of such design and construction as to prevent the possibility of the operator being crushed because of a rollover or upset.
