Aerial lift operators must:
Correct Answer(s)
A. Make a thorough daily visual inspection.
B. Have defective parts impairing safe operations fixed.
C. Fill out an aerial lift inspection form.
D. Have completed the designated operator training and have a current card on their possession.
Explanation
Aerial lift operators must perform a thorough daily visual inspection to ensure that the lift is in proper working condition. They are also responsible for getting any defective parts that may hinder safe operations fixed. Additionally, they need to fill out an aerial lift inspection form to document the inspection process. Lastly, they must have completed the designated operator training and carry a current card as proof of their qualification.
2.
Man lift occupants may position themselves outside of the guardrails if they are tied off.
Correct Answer
B. False
Explanation
Occupants of a man lift should never position themselves outside of the guardrails, even if they are tied off. This is because the guardrails are designed to provide a barrier of protection and prevent falls. Tying off alone is not sufficient to ensure safety, as it does not eliminate the risk of falling. Therefore, the statement is false.
3.
An aerial lift operator must:
Correct Answer(s)
A. Read and understand the Operation and Maintenance Manuals supplied with (and considered part of) the machine.
B. The operator must be skilled and experienced in the operation of aerial lifts and must be thoroughly familiar with the controls, power system and capability of the specific model.
D. Verify maintenance is being performed on the equipment.
Explanation
The correct answer is a combination of three statements:
1. The operator must read and understand the Operation and Maintenance Manuals supplied with the machine. This is important to ensure the operator has the necessary knowledge and information about the machine's operation and maintenance procedures.
2. The operator must be skilled and experienced in the operation of aerial lifts and must be thoroughly familiar with the controls, power system, and capability of the specific model. This is crucial for safe and efficient operation of the aerial lift.
3. The operator must verify that maintenance is being performed on the equipment. This is necessary to ensure that the aerial lift is in proper working condition and to prevent any potential malfunctions or accidents.
4.
Select the true statement(s):
Correct Answer(s)
A. An operator must wear a full body harness while operating a manlift with a telescoping boom.
B. An operator can work in a scissor lift without a full body harness if he follows all of the rules in the district manlift policy.
C. An operator of a manlift with a telescoping boom must fully retract the boom whenever traveling on a grade.
D. An operator of a scissor lift may not drive the lift with the platform raised unless for minor slow adjustments.
Explanation
The correct answer is that an operator must wear a full body harness while operating a manlift with a telescoping boom. This is because working at heights poses a significant risk, and wearing a full body harness can prevent falls and protect the operator in case of an accident. Additionally, an operator can work in a scissor lift without a full body harness if he follows all of the rules in the district manlift policy, as these rules are designed to ensure safety while working in a scissor lift. An operator of a manlift with a telescoping boom must fully retract the boom whenever traveling on a grade to prevent any potential hazards. Finally, an operator of a scissor lift may not drive the lift with the platform raised unless for minor slow adjustments, as this can lead to instability and accidents.
5.
It is safe to position the basket on a building ledge, roof, or any other object and boom down to increase the stability of the basket.
Correct Answer
B. False
Explanation
Positioning the basket on a building ledge, roof, or any other object and booming down does not increase the stability of the basket. In fact, it can be dangerous and increase the risk of tipping or falling. The correct practice is to ensure the basket is properly secured on stable ground or a level surface to maintain stability and prevent accidents.
6.
When moving the machine, the user should visually verify that other people are clear and that potholes or objects that would affect the stability of the lift are avoided.
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that when moving a machine, it is important for the user to visually verify that other people are clear and that any potholes or objects that could potentially affect the stability of the lift are avoided. This is crucial for ensuring the safety of both the user and others around the machine. By visually checking the surroundings and making sure there are no obstacles or people in the way, the user can prevent accidents and maintain the stability of the lift during movement.
7.
Common aerial lift accidents include:
Correct Answer(s)
A. Ejections
C. Smashed Hands
Explanation
The correct answer is "All of the above." Common aerial lift accidents include ejections, cuts, and smashed hands. This means that all of these accidents can occur in aerial lift situations. Ejections can happen if the operator is not properly secured or if the lift is not stable. Smashed hands can occur if the operator's hands get caught between moving parts or if they are not cautious when operating the lift. Cuts can happen due to sharp edges or objects in the lift area. Therefore, all of these accidents are possible in aerial lift situations.
8.
Aerial lift accidents can cause what kinds of injuries?
Correct Answer
D. All of the above.
Explanation
Aerial lift accidents can cause a variety of injuries, including fall injuries, blunt trauma, and electrocution. Fall injuries can occur when workers fall from the lift or when the lift itself falls. Blunt trauma can result from being struck by objects or equipment during an accident. Electrocution can happen if the lift comes into contact with live electrical wires. Therefore, all of the mentioned injuries can be caused by aerial lift accidents.
9.
What must you check before using a scissor lift?
Correct Answer
C. Both A and B
Explanation
Before using a scissor lift, it is important to check both the surface for levelness and stability, as well as ensure that there are no overhead obstructions. These checks are necessary to ensure the safety and stability of the scissor lift during operation.
10.
Load limit stands for what?
Correct Answer
A. Total weight, including body weight, tools and materials, that an aerial lift can safely hold.
Explanation
The load limit refers to the total weight that an aerial lift can safely hold, including the body weight of the operator, as well as any tools and materials that are being carried. It is important to adhere to the load limit to ensure the safety and stability of the aerial lift during operation.
