What can be a consequence of not fully extending an extension ladder before use?

Not fully extending an extension ladder before use can significantly increase the risk of injury. This is primarily because a ladder that is not fully extended may not provide adequate support or stability while in use. When a ladder is extended improperly, it can lead to a loss of balance or slippage, which may cause the firefighter to fall. Additionally, an improperly extended ladder may not reach the desired height, forcing the user to overreach or reposition themselves in unsafe ways, elevating the likelihood of accidental falls or injuries during firefighting operations.

In contrast, fully extending the ladder ensures that it is properly secured and stable, allowing for safer climbing and more effective access to the location needed for firefighting activities. This highlights the importance of following proper procedures when deploying firefighting equipment.
