Which three are requirements for conductors? - ANSWER-They interconnect all air terminals., They may have only one rising path under 50 feet on a pitched roof., They may have only one rising path at less than 1/4 slope on a gently sloping roof.
What is the maximum length a cross-run conductor can run without connection to the roof conductor? - ANSWER-150 feet
Which lightning protection system component is the initial point of contact for a lightning strike? - ANSWER-Strike termination device
The required striking distance and rolling sphere radius for the zone of protection for an ammunition and explosives facility is - ANSWER-100 feet
What is the maximum distance between the edge of a roof and the perimeter air terminal? - ANSWER-24 inches
- / 3
What is the maximum allowed distance between 24-inch air terminals in an integral system or an ammunition storage facility? - ANSWER-25 feet
How far can conductors be coursed through the air without support? - ANSWER-3 feet
While conducting an LPS inspection, you see down conductors like those illustrated in the image below. Do you write it up as a discrepancy? - ANSWER- Yes, because mast down conductors should be as far apart as possible.
Which two precautions should you take when approaching EMR-vulnerable ordnance with a hand-held radio? - ANSWER-Enclose the ordnance completely in a sealed, all-metal container
Turn off the radio when within 10 feet of ordnance
While conducting an LPS inspection, you discover the scenario illustrated in the image below. Do you write it up as a discrepancy? Why or why not? - ANSWER- Yes, because the air terminal is not attached to a conductor.
How many down conductors are required for a building with a perimeter length of 425 feet? - ANSWER-5
Which material is preferred for ground conductors? - ANSWER-copper
If you were inspecting this mast, would you report a defect? - ANSWER-Yes, the down conductors are supposed to be protected.
- / 3
What is the preferred method of connecting conductors? - ANSWER-Exothermic weld
Which two statements about bonding are true? - ANSWER-Bonding electrically connects a metal object to an LPS., Bonding reduces the risk of side flash.
Which bonding method is the most secure? - ANSWER-Welding
Which condition is most common for AE facilities? - ANSWER-Condition 2a
Which object is always required to be bonded? - ANSWER-A railroad track 4 feet from an LPS conductor
Which condition applies to a 2-foot-long grounded metal object on a 15-foot-tall structure? - ANSWER-Condition 2a
Which four statements are characteristics of lightning? - ANSWER-Lightening heats the air to 50,000F., Most lightening never reaches the ground., Lightening carries about 30,000 amps of current., Lightening is about 1" thick.
Place the steps of lightning formation in the correct order. - ANSWER-1. Change forms in a cloud
- A stepped leader extends down from the cloud.
- An upward stream extends up from the ground.
- The stepped leader and upward streamer connect and current flows from the
