Osha fixed ladder roof hatch.

D 2 of this section with minimum clearances for intermediate pitches varying between these two limits in proportion to the slope except as provided in subparagraphs 3 and 5 of this paragraph. Section 1910 28 establishes the employer s duty to provide fall protection for employees on fixed ladders and 1910 29 specifies the criteria for fall protection systems for fixed ladders. Section 1910 27 c 7 and figure d 6 attached specify the relationship for a fixed ladder to an acceptable hatch cover but there is no specific requirement for grab bars. Osha standard for roof openings roof hatch protection is addressed by osha standard 26 cfr 1910 23 entitled guarding floor and wall openings and holes full text of this standard is available online at www osha gov.

Figure d 2 slide step fixed ladder sections. Grab bars not required at hatch exits. Note to paragraph d. Osha s general industry standard for fixed ladders is found in 29 cfr 1910 27.

1910 23 open roof hatches should be protected. Figure d 3 example of counterbalanced hatch cover at roof. Per osha 1910 23 b 4 ladder rungs steps and cleats have a minimum clear width of 16 inches measured before installation of ladder safety systems for fixed ladders. The minimum perpendicular clearance between fixed ladder rungs cleats and steps and any obstruction behind the ladder shall be 7 inches 18 cm except in the case of an elevator pit ladder for which a minimum perpendicular clearance of 4 1 2 inches 11 cm is required.

On fixed ladders the perpendicular distance from the centerline of the rungs to the nearest permanent object on the climbing side of the ladder shall be 36 inches for a pitch of 76 degrees and 30 inches for a pitch of 90 degrees fig. As seen in the picture below featuring new ladder system we recommend a wider climbing surface to accommodate a ladder lifeline system and to make the ladder easier to climb. For starters prior to the new ruling the only real guidance on fixed ladders came from the construction standards osha more 1926 1053 a 18 required the use of cages wells ladder safety devices or self retracting lifelines for fixed ladders of 24 feet or more. Osha s new ruling was designed in part to create more uniformity between the general industry and construction standards.
