What is the recommended practice when using a mobile ladder with handrails?

The recommended practice when using a mobile ladder with handrails is to keep at least two points of contact. This practice is crucial for maintaining stability and ensuring safety while ascending or descending the ladder. By keeping two points of contact—such as both hands on the handrails or one hand and one foot—individuals can maintain their balance and reduce the risk of falls.

Using a mobile ladder often involves maneuvering and reaching, which can shift a person's center of gravity. Two points of contact provide a secure grip, allowing the user to focus on their work without worrying about losing their balance. This method also aligns with general ladder safety principles, which emphasize the importance of having a secure hold while climbing to prevent accidents.

The other options do not align with safe practices. Keeping at least one point of contact may provide some safety, but it does not offer the stability needed for safer climbing. Keeping both hands free is not advisable, as it prevents the user from maintaining a solid grip and increases the risk of falling. Climbing without utilizing handrails eliminates an essential safety feature designed to help users maintain their balance and stability, thus significantly increasing the chances of accidents.
