If there is a gas leak in a car where does the fire apparatus position itself?

Explanation:
Gasoline vapors behave as a heavier-than-air hazard, tending to hug the ground and flow downhill with terrain and wind. Positioning the fire apparatus uphill keeps the equipment above the layer where vapors accumulate, reducing the chance that vapors will reach pump panels, hoses, or the vehicle itself and potentially ignite. If there’s wind, staying upwind helps as well, but the uphill placement provides the strongest protection against vapors rolling downhill into your operating area.
