A grinder spark met propane that had been leaking for hours inside a Cape St. Claire home last week. The homeowner never smelled the gas. Fire investigators ruled the blast accidental after an HVAC crew cut a buried propane line during routine work. The explosion killed one person and leveled the house. That missed cue exposes a belief many service techs still carry onto every job: if gas is leaking, you will smell it in time.
