Question 1

Which of the following BEST describes the location of an escalator's manual stop switch?

Accepted Answer

The manual stop switch for an escalator is typically located on a nearby wall or handrail at the top or bottom of the unit. This allows for easy and quick access in case of an emergency or the need to perform maintenance.

Question 2

What type of technical rescue requires the use of lock out/tag out devices to secure power switches?

Accepted Answer

Machinery rescue often involves situations where individuals are trapped in or by machinery, and securing power switches through lock out/tag out devices is crucial to prevent the machinery from being energized during the rescue operation, ensuring the safety of both the victim and the rescuers.

Question 3

When responding to electrical rescue operations, always assume that electrical lines or equipment are:

Accepted Answer

In electrical rescue operations, it's crucial to always assume that electrical lines or equipment are energized to ensure the safety of the responders and the victim. This approach minimizes the risk of electrocution.

Question 4

What type of device BEST fits the following characteristics: small, accelerates quickly, and may have automatic controls?

Accepted Answer

Passenger elevators are designed to be small and efficient, often featuring automatic controls for user convenience and quick acceleration to move people between floors efficiently.

Question 5

When an energized wire is in contact with the ground, the current:

Accepted Answer

Current flows in all directions from the point of contact when an energized wire touches the ground, dispersing through the ground away from the contact point.

Question 6

During an elevator rescue, extrication should begin immediately if occupants:

Accepted Answer

Extrication should begin immediately if occupants require medical attention to ensure they receive the necessary care as quickly as possible.

Question 7

Large banks of fixed lights have a capacity of ________per light.

Accepted Answer

Large banks of fixed lights typically have a capacity of 500 to 1,500 watts per light. This range allows for significant illumination while managing energy consumption and heat production.

Question 8

Which of the following emergency scene lighting equipment has the disadvantage of contaminating the scene with exhaust fumes if the vehicle is not positioned downwind?

Accepted Answer

Vehicle-mounted generators can contaminate the scene with exhaust fumes if not positioned downwind, as they produce exhaust while generating power for lighting.

Question 9

The telescoping stand on a portable light:

Accepted Answer

The telescoping stand on a portable light allows it to be raised and directed more effectively, enhancing the illumination of specific areas as needed.

Question 10

Hydraulic elevator operating systems are used in structures less than _________stories high.

Accepted Answer

Hydraulic elevator systems are typically used in buildings that are less than six stories high due to their limitations in speed and height capabilities.

Question 11

If an elevator is equipped with a ______it will return to the ground floor by inserting a key into the control panel.

Accepted Answer

A recall system in elevators is designed to automatically bring the elevator to the ground floor in case of emergencies, such as fires, by using a key in the control panel. This feature is crucial for ensuring that the elevator does not stop at the floor where the hazard is present and is part of the building's fire safety protocols.

Question 12

Which of the following emergency scene lighting equipment is typically light enough to be carried by two people?

Accepted Answer

Portable electric generators are designed to be relatively lightweight and mobile, making them capable of being carried by two people to provide power for lighting and other equipment at emergency scenes.

Question 13

Which of the following BEST describes the cause of the majority of escalator rescues?

Accepted Answer

The answer of Which of the following BEST describes the...

Question 14

Which of the following BEST describes the result of using equipment that exceeds extension cord capacity?

Accepted Answer

Using equipment that exceeds the capacity of an extension cord can lead to overheating, which poses an electrical hazard due to the risk of fires or electrical shocks.
