A ladder shall extend at least how many centimeters from the trench bottom to ground level?

Explanation:
Access to a trench requires a ladder long enough to reach ground level from the trench bottom so a worker can climb out safely. The minimum length of 60 cm provides enough reach for a secure handhold and a stable transition from the trench to the surface. If the ladder were shorter, it might not reach ground, forcing awkward movements or a higher risk of slips and falls. So, 60 cm is the minimum extension needed for safe egress.
