What should be ensured when working on a roof using a ladder?

When working on a roof using a ladder, it is crucial that the ladder extends at least three feet above the edge of the roof. This extension provides extra stability and support, allowing the person using the ladder to safely step on and off the roof without losing balance. The added height helps to ensure that the individual maintains a secure grip while transitioning from the ladder to the roof or vice versa.

Having the ladder extend beyond the roof edge also reduces the risk of slipping or falling, as it allows for a more secure handhold when getting on and off the ladder. This is an essential safety measure in ladder safety training, as it directly addresses the risks associated with working at heights. For safety compliance and to minimize the chance of accidents, adhering to this guideline is key when using a ladder on roofs.
