Fixed Ladders |
||||||
|
Another feature of fixed
ladders is the landing platform
which provides a means of interrupting a free fall and serves as a resting place during
long climbs. When fixed ladders are used to ascend to heights exceeding 20 feet (except on chimneys), landing platforms shall be provided for each 30 feet of height or fraction thereof. When cages are used, except that, where no cage, well, or ladder safety device is provided, landing platforms shall be provided for each 20 feet of height or fraction thereof. Ladder safety devices may be used on tower ladders, water tank ladders, and chimney ladders over 20 feet in unbroken length in lieu of cage protection. No landing platform is required in these cases. |
