AMENDATORY SECTION (Amending Order 94-16, filed 9/30/94, effective
WAC 296-24-07801 General. (1) The employer shall ensure that each
affected employee ((
shall)) uses appropriate eye or face protection when
exposed to eye or face hazards from flying particles, molten metal,
liquid chemicals, acids or caustic liquids, chemical gases or vapors, or
potentially injurious light radiation.
(2) The employer shall ensure that each affected employee ((
uses eye protection that provides side protection when there is a hazard
from flying objects. Detachable side protectors (e.g., clip-on or
slide-on side shields) meeting the pertinent requirements of this section
(3) The employer shall ensure that each affected employee who wears
prescription lenses while engaged in operations that involve eye hazards
shall)) wears eye protection that incorporates the prescription in its
design, or (( shall)) wears eye protection that can be worn over the
prescription lenses without disturbing the proper position of the
prescription lenses or the protective lenses.
(4) Eye and face PPE shall be distinctly marked to facilitate identification of the manufacturer.
(5) The employer shall ensure that each affected employee ((
uses equipment with filter lenses that have a shade number appropriate
for the work being performed for protection from injurious light
radiation. The following is a listing of appropriate shade numbers for
Size 1/32 Protective
Operations (inches) Arc Current Shade
arc welding Less than 3 Less than 60 7
3-5 60-160 8
5-8 160-250 10
More than 8 250-550 11
Gas metal arc welding
and flux cored arc Less than 60 7

Gas Tungsten arc Less than 50 8
welding 50-150 8
Air carbon (Light) Less than 500 10
Arc cutting (Heavy) 500-1000 11
Plasma arc welding Less than 20 6
Plasma arc cutting (Light) Less than 300 8
(Medium)** 300-400 9
(Heavy)** 400-800 10
Torch brazing 3
Torch soldering 2
Carbon arc welding 14
Plate Plate Minimum*
thickness thickness Protective
Operations (inches) (mm) Shade
Light Under 1/8 Under 3.2 4
Medium 1/8 to 1/2 3.2 to 12.7 5
Heavy Over 1/2 Over 12.7 6
Light Under 1 Under 25 3
Medium 1 to 6 25 to 150 4
Heavy Over 6 Over 150 5
* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs the yellow or sodium line in the visible light of the (spectrum) operation.
** These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the workpiece.
(6) Criteria for protective eye and face devices.

AMENDATORY SECTION (Amending WSR 95-17-036, filed 8/9/95, effective
WAC 296-155-527 Appendix A to WAC 296-155-525. Due to crane design configuration to maintain mobility, sheave diameters and rope, design factors are limited. Because of these limited design parameters, inspection to detect deterioration in accordance with subsections below and timely replacement are essential.
(1) Frequent inspection.
(a) All running ropes in service should be visually inspected once each working day. A visual inspection shall consist of observation of all rope which can reasonably be expected to be in use during the day's operations. These visual observations should be concerned with discovering gross damage, such as listed below, which may be an immediate hazard:
(i) Distortion of the rope such as kinking, crushing, unstranding, birdcaging, main strand displacement, or core protrusion. Loss of rope diameter in a short rope length or unevenness of outer strands should provide evidence that the rope or ropes must be replaced.
(ii) General corrosion.
(iii) Broken or cut strands.
(iv) Number, distribution and type of visible broken wires. (See subsection below for further guidance.)
(v) Core failure in rotation resistant ropes. When such damage is discovered the rope shall be either removed from service or given an inspection as detailed in periodic inspection.
(b) Care shall be taken when inspecting sections of rapid deterioration such as flange points, crossover points and repetitive pickup points on drums.
(c) Care shall be taken when inspecting certain ropes such as the following:
(i) Rotation resistant ropes, because of their higher susceptibility to damage and increased deterioration when working on equipment with limited design parameters. The internal deterioration of rotation resistant ropes may not be readily observable.
(ii) Boom hoist ropes, because of the difficulties of inspection and the important nature of these ropes.
(2) Periodic inspection.
(a) The inspection frequency shall be determined by a qualified person and shall be based on such factors as expected rope life as determined by experience on the particular installation or similar installations, severity of environment, percentage of capacity lifts, frequency rates of operation, and exposure to shock loads. Inspections need not be at equal calendar intervals and should be more frequent as the rope approaches the end of its useful life. This inspection shall be performed at least annually.
(b) Periodic inspections shall be performed by a qualified person. This inspection shall cover the entire length of rope. Only the surface wires of the rope need be inspected. No attempt should be made to open the rope. Any deterioration resulting in an appreciable loss of original strength, such as described below, shall be noted and determination made as to whether further use of the rope would constitute a hazard:
(i) Points listed in subsection (1) of this section (Frequent inspection).
(ii) Reduction of rope diameter below nominal diameter due to loss of core support, internal or external corrosion, or wear of outside wires.
(iii) Severely corroded or broken wires at end connections.
(c) Care shall be taken when inspecting sections of rapid deterioration, such as the following:
(i) Sections in contact with saddles, equalizer sheaves, or other sheaves where rope travel is limited;
(ii) Sections of the rope at or near terminal ends where corroded or broken wires may protrude.
(3) Rope replacement.
(a) No precise rules can be given for determination of the exact time for replacement of rope, since many variable factors are involved. Continued use in this respect depends largely upon good judgment by an appointed or authorized person in evaluating remaining strength in a used rope after allowance for deterioration disclosed by inspection. Continued rope operations depends upon this remaining strength.
(b) Conditions such as the following shall be sufficient reason for questioning continued use of the rope or increasing the frequency of inspection:
(i) In running ropes, six randomly distributed broken wires in one lay or three broken wires in one strand in one lay (for special conditions relating to rotation resistant rope refer to paragraph 5-22.214.171.124 (d)(1)(b) ANSI\ASME B30.5 1989).
(ii) One outer wire broken at the point of contact with the core of the rope which has worked its way out of the rope structure and protrudes or loops out from the rope structure. Additional inspection of this section is required.
(iii) Wear of one-third the original diameter of outside individual wires.
(iv) Kinking, crushing, birdcaging, or any other damage resulting in distortion of the rope structure.
(v) Evidence of any heat damage from any cause.
(vi) Reductions from nominal diameter of more than:
(A) 1/64 in. (0.4 mm) for diameters up to and including 5/16 in. (8.0 mm);
(B) 1/32 in. (0.8 mm) for diameters 3/8 in. (9.5 mm) to and including 1/2 in. (13.0 mm);
(C) 3/64 in. (1.2 mm) for diameters 9/16 in. (14.5 mm) to and including 3/4 in. (19.0 mm);
1/6 in. (1.6 mm) for diameters 7/8 in. (22.0 mm) to and
including 1 1/8 in. (38.0 mm).)) 1/16 in. (1.6 mm) for diameters 7/8 in.
(22.0 mm) to and including 1 1/8 in. (29.0 mm);
(E) 3/32 in. (2.4 mm) for diameters 1 1/4 in. (32.0 mm) to and including 1 1/2 in. (38.0 mm).
(vii) In standing ropes, more than two broken wires in one lay in sections beyond end connections or more than one broken wire at an end connection.
(c) Replacement rope shall have a strength rating at least as great as the original rope furnished or recommended by the crane manufacturer. Any deviation from the original size, grade, or construction shall be specified by a rope manufacturer, the crane manufacturer or a qualified person.
(d) Rope not in regular use. All rope which has been idle for a period of a month or more due to shutdown or storage of a crane on which it is installed shall be given an inspection before it is placed in service. This inspection shall be for all types of deterioration and shall be performed by an appointed or authorized person.
(e) Inspection records:
(i) Frequent inspection; no records required.
(ii) Periodic inspection: In order to establish data as a basis for judging the proper time for replacement, a dated report of rope condition at each periodic inspection shall be kept on file. This report shall cover points of deterioration. If the rope is replaced only that part need be recorded.
(f) A long-range inspection program should be established and should include records on the examination of ropes removed from service so that a relationship can be established between visual observation and actual condition of the internal structure.
(4) Rope maintenance.
(a) Rope should be stored to prevent damage or deterioration.
(b) Unreeling or uncoiling of rope shall be done as recommended by the rope manufacturer and with care to avoid kinking or inducing a twist.
(c) Before cutting a rope, seizings shall be placed on each side of the place where the rope is to be cut to prevent unlaying of the strands. On preformed rope, one seizing on each side of the cut is required. On nonpreformed ropes of 7/8 in. (22 mm) diameter or smaller, two seizings on each side of the cut are required, and for nonpreformed rope of 1 in. (26 mm) diameter or larger, three seizings on each side of the cut are required.
(d) During installation, care should be exercised to avoid dragging of the rope in dirt or around objects which will scrape, nick, crush, or induce sharp bends in it.
(e) Rope should be maintained in a well lubricated condition. It is important that lubricant applied as part of a maintenance program shall be compatible with the original lubricant, and to this end, the rope manufacturer should be consulted; lubricant applied shall be of the type which does not hinder visual inspection. Those sections of rope which are located over sheaves or otherwise hidden during inspection and maintenance procedures require special attention when lubricating rope. The object of rope lubrication is to reduce internal friction and to prevent corrosion.
(f) When an operating rope shows greater wear at well-defined localized areas than on the remainder of the rope, rope life can be extended (in cases where a reduced rope length is adequate) by cutting off a section at the worn end, and thus shifting the wear to different areas of the rope.
(5) Operating near electric power lines:
(a) Cranes shall be operated so that no part of the crane or load
enters into the danger zone.
Exceptions: The danger zone may be entered if the electrical distribution and transmission lines have been de-energized and visibly grounded at the point of work; or the danger
zone may be entered if insulating barriers (not a part of nor an attachment to the crane) have been erected to prevent physical contact with the lines.
(i) For lines rated 50 kV. or below, minimum clearance between the lines and any part of the crane or load (including handling appendages) shall be 10 feet (3 m).
(ii) Caution shall be exercised when working near overhead lines because they can move horizontally or vertically due to wind, moving the danger zone to new positions.
(iii) While in transit with no load and boom lowered, the clearance shall be as specified in WAC 296-155-525 (3)(e).
(iv) A qualified signal person shall be assigned to observe the clearance when the crane moves to within a boom's length of the limits specified in WAC 296-155-525 (3)(e). The operator is not in the best position to judge distance between the power line and the crane or its protuberances.
(b) If cage-type boom guards, insulating links, or proximity warning devices are used on cranes, such devices shall not be a substitute for the requirements of WAC 296-155-525 (3)(e), even if such devices are required by law or regulation. In view of the complex, invisible, and lethal nature of the electrical hazard involved, and to lessen the potential of false security, limitations of such devices, if used, shall be understood by operating personnel and tested in the manner and intervals prescribed by the manufacturer of the device. Compliance with WAC 296-155-525 (3)(e) is the recommended practice of this regulation in determining permissible proximity of the crane and its protuberances, including load, to electrical power lines.
(c) Before the commencement of operations near electrical lines, the person responsible for the job shall notify the owners of the lines or their authorized representatives, provide them with all pertinent information, and request their cooperation.
(d) Any overhead wire shall be considered to be an energized line unless and until the person owning such line or the electrical utility authorities verify that it is not an energized line.
(e) Exceptions to this procedure, if approved by the owner of the electrical lines, may be granted by the administrative or regulatory authority if the alternate procedure provides protection and is set forth in writing.
(f) Durable signs shall be installed at the operator's station and on the outside of the crane warning that electrocution or serious bodily injury may occur unless a minimum clearance of 10 feet (3 m) is maintained between the crane or the load being handled and energized power lines. Greater clearances are required because of higher voltage as stated in WAC 296-155-525 (3)(e). These signs shall be revised when local jurisdiction requires greater clearances.
(6) Site preparation and erection.
(a) All load bearing foundations, supports, and rail tracks shall be constructed or installed to support the crane loads and to transmit them to the soil or other support medium. In addition to supporting vertical load, foundations and supports, rail supports excepted, should be designed to provide a moment resisting overturning equal to a minimum of 150% of the maximum crane overturning moment.
(b) Rails should be level and straight, unless specifically designed for curves or grades, and properly spaced for the crane trucks in accordance with the manufacturer's specifications. The track and support system should have sufficient rigidity to limit dynamic oscillations and deviations from plumb.
(c) Rails shall be securely attached to the supporting surface in a manner capable of resisting the horizontal and vertical loads specified by the manufacturer. When applicable, provisions should be made for thermal expansion and contraction.
(d) Splices in rail tracks (bolted or welded) shall have smooth joints.
(e) When required, a designated portion of the track should be arranged and constructed as an out-of-service parking area complete with means needed for supporting the crane against storm wind effects and anchoring it against unwanted movement along the track; the parking track should be in place before erection commences.
(f) Rails shall be electrically grounded when they carry cranes electrically powered from an outside source.
(g) Both ends of all tracks shall be provided with stops or buffers adjusted for simultaneous contact with both sides of the travel base.
(h) When more than one crane will be operating on a run of track, particular consideration should be given to the number and disposition of parking areas.
(i) The hazard of earthquake effects appropriated to the site or zone should be considered.
(j) The crane manufacturer shall provide maximum resulting loads at the base of the crane, or wheel loads, for use in design of the supports.
(7) General erection requirements.
(a) When cranes are erected, the manufacturer's or a qualified person's written erection instructions and a list of the weights of each component to be erected shall be at the site.
(b) Cranes shall be erected in accordance with the crane manufacturer's or a qualified person's recommendations. Erection shall be performed under the supervision of a qualified person.
(c) Procedures shall be established before erection work commences to implement the erection instructions and to adapt them to the particular needs of the site. The need for temporary guying and bracing during erection shall be established.
(d) Before crane components are erected, they shall be visually inspected for damage. Damaged members shall not be erected until repaired in accordance with the manufacturer's or qualified person's instructions, or replaced.
(e) Slings and lifting accessories shall be selected and arranged to avoid damaging or marring crane members during erection.
(f) Wind velocity at the site at the time of erection should be considered as a limiting factor that could require suspending the erection operation.
(g) Crane towers shall be erected plumb to a tolerance that is specified by the manufacturer.
(h) Cranes required to weathervane when out-of-service shall be
installed with clearance for the boom and superstructure to swing a full
360 arc without striking a fixed object or other crane.
