Gas leak near appliance — San Francisco, California
SAFETY FIRST: if you smell the distinctive rotten-egg odor of natural gas (mercaptan) near a stove, furnace, water heater, or gas line, evacuate everyone from the building immediately. Do not flip light switches, use phones indoors, or start vehicles in the garage — any spark can ignite the gas. Once outside, call your gas utility's emergency line, then 911 if the odor is strong. A gas leak is typically caused by a loose or corroded fitting, a cracked flexible connector (appliance line), a failed gas valve, or a pilot light that blew out and is releasing unburned gas. After the utility confirms the area is safe, a licensed plumber or gas-line technician pressure-tests the supply lines, tightens or replaces fittings, and checks every appliance connection. Even a small leak that you barely smell can accumulate in enclosed spaces to explosive levels, so never ignore the odor or attempt DIY repair.

San Francisco's Victorian and Edwardian housing stock hides original galvanized and cast-iron pipes long past their service life, prone to corrosion and low pressure. Hilly terrain complicates drainage, and seismic shifting periodically cracks pipe joints and sewer laterals.
