What is one of the critical factors in ensuring safety while working on ladders or lifts?

Maintaining at least two contact points at all times is essential for safety while working on ladders or lifts because it significantly reduces the risk of falls. This principle focuses on ensuring that the worker has a stable grip and footing, thereby enhancing balance and support. By keeping two points of contact, such as one hand and one foot, or both hands and one foot, the individual minimizes the possibility of slipping and losing their grip. This practice allows the worker to maintain stability even if they inadvertently shift their weight or lose balance temporarily.

In contrast, using a metal ladder for stability may not always be the best choice, as it could pose risks in environments with electrical hazards. Scaling without safety gear completely disregards personal protection, exposing the worker to potential injuries. While having co-workers hold the ladder can provide additional support, it relies on the cooperation and awareness of others, which may not always be feasible in every situation. Therefore, prioritizing the maintenance of two contact points is a fundamental and practical method to ensure safety when using ladders or lifts.
