6.1.1 All ground ladders shall be inspected and tested in accordance with the manufacturer's recommendations and to the requirements established by this standard. 

6.1.2 Ground ladders shall be visually inspected at least once every month and after each use. 

6.1.3 A visual inspection shall include, but not be limited to, the following: 

(1)      Heat sensor labels on metal and fiberglass ladders, and on wood ladders if provided, for a change indicating heat exposure 

(2)      All rungs, for snugness and tightness 

(3)      All bolts and rivets, for tightness; bolts on wood ladders, for snugness and tightness without crushing the wood 

(4)      Welds, for any cracks or apparent defects 

(5)      Beams and rungs, for cracks, splintering, breaks, gouges, checks, wavy conditions, or deformation 

(6)      Butt spurs, for excessive wear or other defects 

(7)      Halyards, for fraying or kinking 

(8)      Roof hooks, for sharpness and proper operation 

(9)      Rungs, for punctures, wavy conditions, worn serrations in the foot contact areas, serrations worn down to base metal in any location, or deformation

(10)      Loss of base metal due to corrosion

(11)      Ladder slide areas, for galling or absence of wax, if required by the manufacturer 

(12)      Loss of gloss on fiberglass and wood ladder beams, damage to the varnish finish on wood ground ladders 

(13)      Correct operation of the pawl assemblies 

(14)      Wire rope on 3- and 4-section ladders for snugness when the ladder is in the bedded position, to ensure proper synchronization of upper sections during operation 

(15)*      Labels present and legible 

(16)       Ladders clean with no buildup of grease, dirt, or grime on the beams

(17)        The diagonal brace on the base of a folding ladder for damage

(18)         The hinge assembly and locking pin assemblies on a multi-purpose ladder for the presence of any visual damage and for their proper operation

6.1.31 All conditions found unacceptable during the subject visual inspection shall be corrected prior to the ladder being returned to service          

6.1.4 The ground ladder shall be removed from service if there are any signs of damage beyond gouges or dents or if defective parts or welds are discovered during the visual inspection. 

6.1.4.1* If the ground ladder is removed from service, it shall be obviously marked as “out of service” with the date and a description of the defect requiring the ladder to be removed from service. 

6.1.4.2 The ladder shall be repaired in accordance with the manufacturer's instructions, and service tested in accordance with Section 7.2, Section 7.3, or Section 7.4 as applicable, before it is returned to service, or it shall be destroyed. 

6.1.5 Gouges and Dents. 

6.1.5.1 If gouges and dents are discovered in a beam during the visual inspection, the ladder shall be subjected to the applicable load test as specified in Chapter 7. 

6.1.5.2 Gouges and dents in a beam shall not be cause to fail a ladder if it passes the applicable load test.

6.1.5.3 If gouges or dents are discovered in a rung, the manufacturer shall be consulted regarding the need for repair prior to the ladder being returned to service.  

6.1.6 If a wood ground ladder develops dark streaks in the beams, the ladder shall be removed from service and shall be service tested as specified in Chapter 7 prior to further use.

6.2.4 Ground ladders shall not be painted except for the top and bottom 460 mm (18 in.) of each section for purposes of identification or visibility. 

6.2.5* Pawl assemblies on extension ladders shall be kept clean and lubricated in accordance with the manufacturer's instructions. 

6.2.6 Ladder slide areas on extension ladders shall be kept lubricated in accordance with the manufacturer's instructions.

6.2.9 The surface finish on ground ladders shall be maintained in accordance with the ladder manufacturer's recommendations. 

6.2.10 Heat Sensor Labels. 

6.2.10.1 If the heat sensor label has an expiration date and that date has passed, or there is no date on the label, the heat sensor label shall be replaced. 

6.2.10.2 If the ladder is constructed of metal or fiberglass materials and does not have heat sensor labels, the ladder shall be tested in accordance with Chapter 7. 

6.2.10.2.1 If the ladder passes all the tests, heat sensor labels shall be applied to the ladder. 

6.2.10.2.2 For all ladders except folding ladders and multi-purpose ladders, the heat sensor labels shall be located on the inside of each beam of each section immediately below the second rung from the tip of each section and in the center of that section. 

6.2.10.2.3 For folding ladders, the heat sensor labels shall be permitted to be applied to either the inside or outside of the ladder and shall be located immediately below the second rung from the tip of the ladder and in the center of the ladder.

6.2.10.2.4 For multi-purpose ladders, the heat sensor labels shall be located on the inside of each beam of each telescoping section assembly approximately 150 mm (6 in.) below the hinge assembly and also 150 mm (6 in.) from the bottom of each of the sections forming the telescoping section assemblies.
