CH. 5 Emergency Management/Storm Response Flashcards
24 hours a day, 7 days a week
24-7
A method to determine the severity and likelihood of risk
5X5 matrix
A process whereby a electricity is fed back into downed lines, usually from a home generator that can re-energize the lines; the voltage can be raised if it passes through a transformer.
Back feed
The person at the utility or line clearance company who is in control of sending the line clearance crews to work locations
Dispatcher
Properly providing a path for the flow of electricity to prevent accidental energizing of a power line
Grounded
Line clearance crews that are on standby 24 hours a day, seven days a week and can be called to an emergency at relatively short notice
On call
A person designated as the leader or controller of an emergency situation or operation
Person in charge
Personal safety gear such as hard hat, safety glasses, and hearing protection
Personal protective equipment PPE
Distribution lines that carry voltage ranging from 2400 to 34,500 volts
Primary lines
The process of assessing the risks posed by a job task such that the identified risks can be reduced or eliminated, making the job safer for personnel; process of determining the level of risk posed by a tree or group of trees on a property
Risk assessment
Circuits that carry lower voltages from distribution transformers to the point of use
Secondary lines
Refers to issues, situations, risks, dangers, and other factors that are unique to a particular worksite or emergency situation
Site specific
Refers to the time when crews are released from a call or 24-7 status to return to normal working hours
Stand down
A device used to facilitate communication between two parties such as crews and crew leaders, crew leader and dispatcher, or dispatcher and utility person in charge
Two way radio
Safety standards care operations, approved by the American National Standards Institute. These safety standards are for pruning, trimming, repairing, maintaining, and removing trees and cutting brush
ANSI Z133.1-2000
Major storms or _____ weather events are the usual cause of power outages over large areas.
Catastrophic
Crew mobilization for a storm event is much more rapid from a _______status.
Standby
The _______standards are voluntary safety standards for pruning, trimming, repairing, maintaining and removing trees, and cutting brush.
ANSI Z133
On a storm site, cutting should not begin until all risks have been assessed in the_______approach decided in adopted.
Safest
As clearance work progresses,________between crews and dispatcher is critically important to determine locations of downed or damaged lines.
Communication
One of the highest personal risks and storm work is________.
Fatigue
Always consider that all lines are_______.
Energized
The sound of a running home generator should alert crews to the possibility of________.
Back feed
Crew members should always refer customer questions about the status of power restoration to the_________.
Utility
Customer relations are important during a storm response but are necessarily a low priority than_______and power restoration.
Safety
An electrical backfeed may be caused by:
And operating home generator
When responding to a storm emergency, the highest priority for crews should be to:
A. Remove all trees with past trim refusals
B. Work on circuits with the most tree damage
C. Work on circuits feeding hospitals
Work on circuits feeding hospitals
When arriving at a storm site, the highest priority for the crew foreman is to immediately identify and locate:
A.down the electrical lines.
B. Downed or damage poles and other equipment.
C. Trees and or branches hanging in the lines.
D. An escape route
Downed electrical lines
A basic guideline to follow in storm emergency work is two:
A. consider CATV and telephone lines to be safe
B. keep the customer satisfied
C. consider all wires energized
D. cut first and ask questions later
Consider all wires energized
Which of the following conditions is most likely to fail and causing electrical outage in a moderate storm?
A. An open trunk cavity
B. Code dominant leaders with included bark
C. Overhanging, live branches
D. A D current tree form
Overhanging, live branches
