  1. how do customers view the quality of service provided by the utility company
    the reliability of their power
  2. why is there a need to perform live line work
    the dependence by society on the availability of electric power
  3. when referring to rubber cover up equipment what does the class of protective equipment refer to
    maximum phase to phase use voltage
  4. how should rubber blankets be stored
    laid flat or rolled
  5. when working on energized lines with rubber gloves, how does one determine what class of glove to use
    phase to phase voltage
  6. when does OSHA allow rubber sleeves not to be worn
    if exposed energized parts on which work is not being preformed are insulated from the employee, and if such insulation is placed from a position not exposing the employee's upper are to contact with other energized parts
  7. when should rubber gloves be visually inspected and air tested
    before each use
  8. who can rubber glove
    qualified employees who have been trained in the specific procedures and techniques can work on energized lines
  9. when rubber gloving, what does it mean to insulate
    the lineworker shall be insulated from the energized phase by the use of properly rated rubber protective equipment
  10. as a minimum OSHA states that rubber gloves, sleeves and blankets, will be tested when
    • before each issue and
    • every 6 mths for gloves
    • every 12 mths for sleeves and blankets
  11. define second point of contact
    the point at which current leaves the body in the event of accidental contact between energized conductors (or equipment) and an unprotected part of the body
  12. what milestone was reached with A B chance
    in 1948 hot line tool specialists of the A B chance company replaced insulators hot on the 287KV line supplying power to Los Angeles from Hoover Dam
  13. when rubber gloving what does it mean to isolate
    to isolate from any path to ground by the use of an insulated aerial vehicle or insulated platform
  14. electric utilities need to provide the best consumer service possible. striving to minimize costs and maximize value. congruent with these basic core values, consumers regard reliability of service as a distinct indication of ______ of service
    quality
  15. the ability to preform transmission live line work can result in significant ______ for a utility along with improved reliability
    savings
  16. describe the condition that would allow a lineworker to encroach on the minimum approach distance, or in other words the condition or practice that would allow a limeworker to come closer to an energized conductor than the minimum approach distance
    if a conductor is covered with approved protective equipment
  17. virtually all live line tools in use today are made of what materials
    fiberglass reinforced plastic
  18. generally the core of a hot stick is made of what material
    foam
  19. what is the purpose of the core material in a hot stick
    inhibits moisture absorption
  20. live line tools should be used, transported, and stored in a manner to ____ _____ __ _______
    prevent exposure to moisture
  21. how often should live line tools be removed from service, for examination, cleaning, repair, and testing
    every two years
  22. live line tools are available for use on all distribution and transmission voltages. by contrast, the highest rated rubber gloves (class 4) are used on voltages not greater than
    36,000 volts
  23. the prejob procedures for hot sticking are the same as rubber gloving. after setting up a proper work area of protection list the hot stick procedures that should be followed
    non reclose; work location inspection; equipment inspection; consideration of weather; job briefing
  24. what determination should be made regarding weather conditions when scheduling hot sticking operations if water droplets can form along the length of the stick
    weather or not hot sticking operation should proceed
  25. protective cover up equipment is typically made form two materials
    rubber; high grade plastic
  26. what type of rubber protective equipment is ozone resistant
    type two
  27. what type of rubber protective is not ozone resistant
    type one
  28. what does ozone resistant mean
    sunlight resistance
  29. how should rubber blankets be stored
    rolled or flat
  30. what type of plastic cover up id required when setting poles near energized lines
    pole guards
  31. describe the requirements related to testing plastic cover up equipment
    plastic equipment does not require in service testing unless an inspection would raise uncertainty about the condition
  32. under what condition does OSHA allow rubber sleeves not to be used in conjunction with rubber gloves
    if exposed energized parts on which work is not being preformed are insulated from the employee, and if such insulation is placed from a position not exposing the employee's upper arm to contact with other energized parts
  33. how often must rubber sleeves be tested
    before first issue and every 12 mths there after
  34. typically which entity/entities dictate which voltages can and can not be rubber gloved
    state laws and utility companies
  35. what is the first consideration (as stated in the manual) of rubber gloving
    insulate and isolate
  36. what term is described as the point at which current leaves the body in the event of accidental contact between energized conductors or equipment and an unprotected part of the body
    second point of contact
  37. rubber blankets are required to be tested how often
