Candidates need a working grasp of relative density, calorific value, Wobbe index, flame speed, and the difference between natural gas and LPG. Relative density determines where a leak accumulates: natural gas (lighter than air) rises and collects at high points, while LPG (heavier than air) sinks into low points, pits, and drains.
