Free LA questions: Risks & Damage

These questions are in the practice set above. Answer them there to see the correct option and the explanation for each.

  • What is the main injury risk when a live electricity cable is struck, and what extra risk does this create for a nearby plastic gas pipe in the same trench?
  • Why is a leak of liquefied petroleum gas (LPG) treated as more dangerous underground than a leak of natural gas, and why is gas collecting in cable ducts and chambers also a risk?
  • Scenario: an undertaker is planning street works likely to affect another person's apparatus already in the street. What must it do for its own workforce, and what must it allow the apparatus owner to do?
  • Scenario: an excavator bucket strikes a cable, and the smell of gas is also noticed further along the trench. What should happen with the excavator, and what should be done about the gas?
