A

Front focused

25
Q

What area of the hot stick indicates the sensing section of the tool?

A

Red striped area

26
Q

The distance from a potential source at which the tool will begin to alert depends on what factors?

A

Mode setting, magnitude of AC voltage, distance from source, shielding of potential sources, size of the area where the AC voltage appears to be coming from

27
Q

What is the most common electrical problem the department responds to?

A

“Wires down”

28
Q

Apparatus position and responding personnel are to maintain at least how many spans from affected wire or pole?

A

1 span (distance between poles)

29
Q

If a pole is damaged, the distance between what will provide a best margin of safety (do not count damaged pole)?

A

2 undamaged poles

30
Q

Turn the operating switch to the high setting and listen for a series of rapid beeps and LED flash lasting approximately how many seconds indicating the hot stick is ready for use?

31
Q

The hot stick requires no warm up and is ready for use in how many seconds after turning it on?

32
Q

What setting is utilized when looking for AC voltage in the general area?

33
Q

In the high setting, of high voltage detected in the area, the device will begin beeping at what distances from the source and at a faster rate?

A

Greater distances

34
Q

What setting can be utilized when working around other high voltage sources such as high voltage overhead power lines?

35
Q

What setting will help identify energized wires on or closer to the ground without alerting members to overhead power lines?

A

Low setting

36
Q

In the low setting, the what of the beeping will increase as you move closer to the potential source?

A

Rate and intensity

37
Q

What setting is used to pinpoint a source and will only sound when pointed directly at the energized source?

A

Front focused

38
Q

When responding to TAs with potential electrical hazards, what setting should be used to alert the presence of a hazard from a distance?

39
Q

As you move closer to a vehicle what setting on the hot stick should be used to better identify the presence of electricity?

40
Q

If no detection of the presence of electricity from a distance, continue to use the LOW setting in what direction of the vehicle?

A

Above, below and around all sides

41
Q

What can prevent the hotstick from immediately detecting voltage?

A

Shielding of any wire inside a grounded conduit

42
Q

Shielding of voltage is also possible from what?

A

Large wet trees and other natural objects with enough mass

43
Q

Dragging your feet across the ground with cause what which is caused by friction and is not a true reading of AC voltage but could cause the hot stick to alarm?

A

Electrostatic voltage

44
Q

Consider all electrical wires what until determined otherwise by DWP?

A

“Live” or “hot”

45
Q

What works to restore power during power outages which is not way to predict when this will occur?

A

Automated machinery

46
Q

Accidental regeneration of electricity may occur due to what on a downed wire into another energized source?
