That moment I realized I was drilling into a live gas line
I was installing a wireless alarm panel in a basement remodel in Chicago last month. The homeowner said the wall was clear. I used my stud finder to check for wires and pipes but it didn't pick up anything. I drilled right into a 1/2 inch black iron gas pipe. The hissing sound was immediate. Now I always use a high quality pipe detector before I drill into any wall, even if the customer says it's safe. Has anyone else had a close call like this?
