13-1.6.2 Construction of Platforms
(a) Platforms shall be designed to sustain a distributed load of at least 50 lb/sq ft (2.4 kPa).
Ui) Platforms shall have a slip-resistant walking surface.
(C) Handrails for platforms shall be 36 in. (15 mm) to 42 in. (1067 mm) high with an intermediate rail and a 4 in. (102 mm) to 6 in. (152 mm) toeboard.
(d) L.adder access openings in the platform floor should be approximately 24 in. (610 mm) x 27 in. (685 mm) protected with a hinged hatch cover.
13-1.6.3 Fixed Ladders
Fixed ladders, if provided, shall meet the following requirements:
(a) the minimum design live load shall be a single concentrated load of 250 lb (113 kg), concentrated at such a point which will cause maximum stress in the structural member being considered.
(b) rungs shall have a minimum diameter of in. (19 mm), a maximum distance between rungs of 12 in. (305 mm), and a minimum clear width of 16 in. (406 mm).
(c) a minimum climbing space of 15 in. (381 mm) each way from the centerline of the ladder and 30 in. (762 mm) on the climbing side of the ladder shall be provided except when inside cages or hatchways are used.
(d) the distance from the centerline of the rungs to the nearest permanent object in back of the ladder shall be not less than 7 in. (178 mm).
(e) on ladders over 20 ft (6 m) in height, cages shall be provided from a point not more than 8 ft (2.4 m) above the fkir, to a point not less than 3 ft 6 in. (1.1 m) above the landing platform unless safety devices as per para. 13-1.6.3(0 are provided. Such cages shall be at least 27 in. (685 mm) clear inside diameter.
(ft ladder safety devices may be used on ladders over 20 ft (6 m) in unbroken height in lieu of cage protection. All ladder safety devices such as those that incorporate life belts, friction brakes, and sliding attachments shall meet the design requirements of the ladders that they serve.
(g) when exiting at the top of the ladder, handrails of at least 3 ft 6 in. (1.1 m) shall extend vertically from the top level of the ladder; otherwise, the ladder will extend an additional similar distance above the point of exit.
13-1.6.4 Access to Cab or Service Platform
Access to the cab or service platform shall be by means requiring no step over any gap exceeding 12 in. (305 mm).
13-1.6.5 Personnel Access to Machine Aisles and Runways
Machine aisles and runways shall be clearly designated to be used by authorized personnel only.
