How it's used
Distinguishing between the electrical and environmental meanings relies entirely on context. When discussing electrical work, it is often referred to as 活線 to avoid ambiguity with wildfires. In electrical settings, it is standard to contrast it with 中線 and 地線.

Common mistake
Do not confuse this with the military term for front line, which is 前線. Using 火線 to describe a battle front will sound like you are referring to a literal fire line.
