How many individuals are allowed to work off an extension ladder at once?

Only one individual is permitted to work off an extension ladder at any given time for several critical safety reasons. This regulation is primarily to prevent the risk of the ladder becoming unstable due to additional weight or shifting. When only one person is on the ladder, it helps maintain balance and reduces the potential for accidents such as tipping or falling. Additionally, it is easier for a single worker to manage the load and comply with proper positioning and technique, which are essential for safety while working at elevated heights.

Having more than one person on the ladder can compromise its structural integrity and makes it challenging to navigate safely, increasing the likelihood of an incident. Therefore, adherence to this guideline is crucial in ensuring a safe working environment when using extension ladders.
