Leave the building if you smell gas, see smoke or fire, hear a carbon-monoxide alarm, or anyone has symptoms such as dizziness, confusion, nausea, or unusual weakness.
Turn the system off if there is severe electrical smell, sparking, smoke, major water leakage near electrical equipment, violent vibration, or a new loud mechanical noise. Do not touch wet electrical equipment.
Loss of heat during extreme cold can threaten people, pets, plumbing, and the building. Prioritize safe shelter and protect vulnerable occupants while arranging help.
Repeatedly resetting breakers, safety switches, or equipment can worsen damage or conceal a serious fault. One simple thermostat and power check is enough.
Not always, but it becomes urgent during severe cold, when vulnerable occupants are present, or when there is risk to plumbing or the building.
No. A breaker that trips again may indicate an electrical fault. Leave it off and arrange qualified assessment.
Leave the building, avoid switches or ignition sources, and contact emergency services or the gas utility from a safe location.
