TB 169 - Hot Stick USA AC Flashcards
The Hot Stick USA AC (Hot Stick) was specifically designed with first responders in mind to provide:
warning of EXPOSED high voltage alternating current (AC) from a safe distance.
Signals, coming from an UNSHIELDED, voltage carrying surface will be identified by the Hot Stick via a _____ and ______ warning.
audible and visual
The Hot Stick is NEITHER CAPABLE NOR INTENDED to be used as a voltage READER.
The detector is not designed to identify ______ current voltages.
Direct Current (DC)
Detection Distances Chart:
What operational settings does the Hot Stick have?
-Off
-High
-Low
-Front focused.
When placed in the HIGH or LOW setting the device will respond to voltage signals from _____ sides of the Hot Stick.
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.)
While utilizing the Front focused setting, the device narrows the receiving area to the ______ area.
-front focal
(allowing to pinpoint the source.)
The distance from a potential source at which the tool will begin to alert depends on several factors:
-The setting mode of the switch
-The magnitude of the AC voltage
-The distance of the source
-Possible shielding of potential sources
-The size of the area where the AC voltage appears to be coming from
When onscene of “Wires Down”….
Apparatus position and responding personnel are to maintain at least _____ from the affected wire or pole. If the pole is damaged do not count the damaged pole.
Additionally, the distance between ____ undamaged poles will provide the BEST margin of safety.
-1 span (the distance between two poles)
-Two
Turning on the Hot Stick
Turn the operating switch to the HIGH setting. Listen for a series of rapid beeps and LED flash lasting approximately 3 seconds indicating the Hot Stick is ready for use.
The Hot Stick requires no warm up and is ready for use in _____ seconds after turning it on.
5
Which setting is utilized when looking for AC voltage in the general area?
HIGH
Which setting can be utilized when working around other high voltage sources such as high voltage overhead power lines?
LOW
(This will help to better identify energized wires on or closer to the ground without alerting members to overhead power lines.)
Which setting is utilized to pinpoint a source. It will only sound when pointed directly at the energized source?
Front Focused
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.
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.)
Consider all electrical wires to be “LIVE” or “HOT” until their electrical potential is determined by?
Department of Water and Power (DWP).
