With ladders installed at an angle greater than 70 degrees, landing platforms are required every how many vertical meters?

Explanation:
When a ladder is set at a very steep angle (greater than 70 degrees), safety rules require a resting and transition point after a specific amount of vertical rise to limit fall exposure and give the user a secure place to reorient. The standard calls for a landing platform every 4.5 meters of vertical height. This interval balances the need for frequent safe points with practicality for climbing. So, after climbing 4.5 meters vertically, a landing platform is required. The other distances are not the mandated interval for this steep angle, which is why 4.5 meters is the correct choice.
