Which of the following is a safe operating practice for aerial devices?

Being aware of overhead obstructions is essential for safe operation of aerial devices. Firefighters must maintain situational awareness of their surroundings to avoid hazards that can pose risks during aerial operations. This includes being vigilant about power lines, tree branches, and other structures that might interfere with the movement or extension of the aerial device. Identifying and assessing these obstructions before and during aerial operations helps to prevent accidents, ensuring that responders can operate the equipment safely and effectively.

In contrast, extending the ladder while responders are on it can lead to dangerous situations, as the ladder may become unstable or unsafe during the extension process. Overloading the ladder can result in structural failure, compromising the safety of personnel on board. Retracting the ladder quickly can also introduce risk, as it might not allow for proper clearance from surrounding obstacles, increasing the chances of accidents or injury. Therefore, maintaining awareness of overhead obstructions is recognized as a fundamental safe operating practice for aerial devices.
