Q

When placed in the HIGH or LOW setting the device will respond to voltage signals from _____ sides of the Hot Stick.

A

all sides

(The HIGH setting increases the sensitivity and will alert the user sooner of the presence of an electrical hazard. As the voltage levels increase the device will begin alerting sooner as well.)

Q

Traffic accidents involving potential electrical hazards:

Initially, use the _____ setting which will alert the user of presence of a hazard from safe distance.

When moving closer to vehicle, switch to ______ sensitivity to better identify the presence of electricity and potentially identify the source.

A

High and then Low

(Switching to Front Focused setting will allow the user to scan the rest of the vehicle without any interference from any possible overhead power lines.)

17
Q

The Hot Stick has been tested to operate continuously for 300 hours by the manufacturer. It is recommended to change the four (4) AA batteries at least ______ or when discharged.

A

annually

(If the batteries are low, the tool will emit a solid beeping sound along with a solid LED light when turned on.)

(If only one battery is installed incorrectly, the device will sound continuously and the LED light will illuminate as well.)

18
Q

The Hot Stick consists of a high sensitivity AC amplifier for the frequency range of ____ to _____ Hz.

A

20 to 100 Hz

(The special amplifier is capable of receiving AC signals over a wide amplitude range. This includes low voltage such as 120 volts AC up to and including high voltage.)

19
Q

Firefighters responding to emergencies involving electrical hazards must wear full Personal Protective Equipment (PPE). This includes donning firefighting _____ and gloves.

A

Hood
