1
Chapter One of NFPA® 70E® provides the blueprint for creating an electrical safety program and is the genesis of the safety rules and procedures you must follow while performing electrical-related work.
2
The two main hazards of electricity are ________________________.
3
There are two approach boundaries for electric shock protection: the Limited Approach Boundary and the Restricted Approach Boundary.
4
Arc Flash PPE Category Four requires a tested and verified system of arc-rated clothing of at least 40 calories per square centimeter.
5
Workers may not cross the Arc Flash Boundary unless they are briefed on the hazards and are wearing appropriate arc-rated clothing and protective equipment.
6
You must treat all electrical conductors and circuit parts as energized until the existence of an electrically safe work condition has been properly verified.
7
The Arc Flash Boundary must be placed at an approach limit distance where the amount of thermal energy could result in the onset of a ____________ burn.
8
Section 130.5(H) requires that the owner of electrical equipment install field-labels on equipment that will display the nominal system voltage and the Arc Flash Boundary.
9
Energized work is permitted when the electrical conductors and circuit parts operate at less than _______, and it is determined that there will be no increased exposure to electric burns or to explosion due to electric arcs.
10
The amount of thermal energy at a certain distance from an arc source is known as____________ .
