Buyers smell heating oil under a finished basement during a Saturday showing. What first?
Stop the tour. Move people upstairs and outside as needed. If a buyer feels woozy, the air smells heavy, or nobody can name the liquid, dial emergency services. Do not ask a realtor's handyman to mop toward the laundry drain. From a safe stair landing, note the tank's fill dates and which way any sheen is moving. Give the oil tickets and SDS to responders. The listing agent should cancel the showing, not grab a mop.
