Aerial Lift Quiz

The statement is true because the lift operator is responsible for ensuring the safety of employees working on the ground. If the boom of the lift is over an employee, it poses a significant risk of injury or accident. Therefore, it is the lift operator's duty to ensure that the boom is never positioned over a worker on the ground to prevent any potential harm.

The statement that the type of terrain does not need to be considered when selecting the right type of lift is incorrect. The terrain plays a crucial role in determining the appropriate lift type. Different types of lifts are designed to operate in specific terrains, such as flat surfaces, slopes, or uneven terrain. Factors like slope angle, surface conditions, and obstacles need to be taken into account to ensure the lift's safety and efficiency. Therefore, the type of terrain should be considered when selecting the right lift.

If a worker is 10 feet or more off the ground, additional fall protection equipment is required if someone is in a lift basket. This means that if a worker is working at a height of 10 feet or above, they must have additional safety measures in place to prevent falls. This is especially important if someone is in a lift basket, as there is a higher risk of falling from a raised platform. Therefore, the statement is true.

The number of employees needed affects the type of lift that can be used because different lifts have different weight capacities and sizes. If a project requires a large number of employees to work at heights, a larger lift with a higher weight capacity may be needed to accommodate them safely. Conversely, if only a few employees are needed, a smaller lift may be sufficient. Therefore, the number of employees needed directly impacts the choice of lift to ensure the safety and efficiency of the work.

The statement is false because there are other pre-job inspections that are necessary besides the pre-start inspection of the lift. These inspections may include checking the condition of tools and equipment, inspecting the work area for hazards, and ensuring that all necessary safety protocols are in place. Neglecting these inspections can lead to accidents and injuries, making it important to conduct all necessary pre-job inspections before starting any task.

The statement suggests that lifts should not be used as cranes unless they are specifically designed for lifting loads. This implies that using lifts as cranes without proper design can be dangerous or ineffective. Therefore, the correct answer is True, indicating that lifts should not be used as cranes unless they are designed for it.

A lift cannot be modified as needed if it moves too slowly. Modifying the speed of a lift requires complex adjustments to its mechanical and electrical systems, which may not be feasible or cost-effective. Additionally, altering the speed of a lift without proper expertise and authorization can compromise its safety and functionality. Therefore, the statement is false.

False. If a person moves from a lift platform to a nearby structure, they would require two lanyards. One lanyard would be attached to the lift platform to ensure their safety while on the platform, and another lanyard would be attached to the nearby structure once they reach it to ensure their safety while on the structure.

An aerial lift and a scissor lift are not the same things. While both are types of lifts used for elevated work, they have different designs and functionalities. Aerial lifts are typically larger and have a boom or bucket attached to a hydraulic arm, allowing for vertical and horizontal reach. On the other hand, scissor lifts have a platform that moves vertically using a scissor-like mechanism. Therefore, the statement that they are the same is false.

In the event of an emergency shutdown, it is important to prioritize the safety of individuals. Lowering the lift and ensuring it is securely resting on its supports helps to prevent any potential accidents or injuries. This step ensures that the lift is stable and reduces the risk of it toppling over or causing any harm. Therefore, the statement "the first step is to ensure that the lift is lowered and safely resting on its supports" is true.

According to the given statement, a licensed professional is required to conduct an inspection on a lift every three months or after 150 hours of operation, whichever comes first. This implies that the inspection should be done at regular intervals to ensure the lift's safety and functionality. Therefore, the correct answer is true.

The statement is true because the design of a scissor lift typically includes a platform that is smaller in size compared to the base. This design ensures that the lift remains stable and balanced during operation. By keeping the platform smaller, the weight distribution is evenly spread across the base, reducing the risk of tipping or instability. This is an important safety feature to prevent accidents and ensure the stability of the scissor lift while workers are elevated.

OSHA does not require employees to maintain a 5-foot clearance of all power lines with less than 50 kilovolts. The correct answer is False.

The statement is false because the joint on the boom platform of aerial lifts does not allow the arms to be four times as long. The joint on the boom platform allows the arms to move up and down, but it does not extend the length of the arms. Therefore, the statement is incorrect.
