NFPA 70E Questions and Verified
Solutions 100% Correct Already Graded
A+
Arc Flash Hazard - Answer: A dangerous condition, possible release of energy caused by an electric arc
Arc Rating - Answer: The arc rating is expressed in cal per cm squared ^2
Informational Note No. 1: Arc-rated clothing or equipment indicates that it has been tested for exposure
to an electric arc
Informational Note No. 2: ATPV=Standard Test Method for Determining the Arc Rating of Materials for
Clothing
balaclava - Answer: Sock hood that protects the neck and head except for a small portion of the face
Boundary, Arc Flash - Answer: Calculated distance which one would receive a 2nd degree burn when an
arc flash hazard is present , an approach limit from an arc source 1.2 cal/ cm^2
Boundary, Limited Approach - Answer: An approach limit at a distance from an exposed energized
electrical conductor or circuit part within which a shock hazard exists. If unqualified person is needed
must be escorted by qualified person
Boundary, Restricted Approach - Answer: there is an increased likelihood of electric shock. Qualified
person only wearing PPE
Electrical Safety Program - Answer: A documented program that identifies policies, procedures,
principles and safe work practices to protect workers exposed to electrical energy.
Electrically Safe Work Condition - Answer: A state in which an electrical conductor or circuit part has
been deenergized, loto, tested for no V, and grounded if determined necessary.
, Maintenance, Condition of - Answer: The state of the electrical equipment
Qualified person - Answer: One who has demonstrated competency and knowledge related to
construction and operation of electrical equipment has received safety training to identify hazards and
reduce risk
Risk - Answer: Combo likelihood of occurrence of injury or damage to health and the severity of injury or
damage to health that results from a hazard.
risk assessment - Answer: Process- identifies hazards,
estimates the likelihood of occurrence of injury or damage to health, estimates severity of injury or
damage to health, determines if protective measures are required
working distance - Answer: The distance between a person's face and chest area and an arc source.
Informational Note: Incident energy increases as the distance from the arc source decreases.
Working on - Answer: Hazard, Same as if we were touching it
Employers responsibility and employee - Answer: The employer shall have the following responsibilities:
(1)
Establish, document, and implement the safety-related work practices and procedures
(2)
Provide employees with training.
(B)
Employee Responsibility. The employee shall comply with
the safety-related work practices and procedures provided by the employer.
Priority 110.1 - Answer: Hazard elimination shall be the first priority of safety-related work practices.
