insulated platforms and the second point of contact Flashcards
The second point of contact is where current would leave a Qualified Electrical Worker’s body if contact were made with a hot circuit.
true
If an electrical contact is made, current will flow through a Qualified Electrical Worker’s body, even if not in contact with another object at a different potential.
false
There are ? methods that can be used to protect a Qualified Electrical Worker from contacting a second point of contact when working on distribution lines.
3
An ultimate example of depending on the second point of contact being removed is ? work.
barehand
An insulated boom and bucket provide protection from earth as a second point of contact.
true
The primary protection a Qualified Electrical Worker has while doing barehand work from a bucket is in maintaining the ?
intergrity of the equipotential zone
Protection from a second point of contact is not as likely when working on transmission lines because ?
of the greater approach distances available
Working with rubber gloves from an insulated platform is an exception to the minimum approach distance rule.
false
Both rigid and rubber cover-up is available for transmission line work.
false
When in contact with a live conductor, a second point of contact with cover-up installed on it may be approached closer than the minimum approach distances.
true
A pole-mounted insulated platform does not need to be on an electrical retesting schedule.
false
The most common insulated platform in use by Qualified Electrical Workers is a(n) ?
aerial device
If working with rubber gloves, stay at a minimum approach distance from all second points of contact.
true
The part of the bucket on a bucket truck or aerial lift that is electrically tested is the ?
liner
If a bucket truck is unavailable, an insulated pole platform should be mandatory when working with rubber gloves.
