Water emergencies create hazards that go beyond the water itself, and a few are serious enough to override any urge to start cleaning up. Electricity is the first: water in contact with outlets, a panel, or wiring can be deadly, and power should be shut off at the breaker only if you can reach it from a dry spot without standing in or touching water. If you cannot do that safely, the safe move is to stay clear and wait for help rather than risk it. A burning or gas odor, or any doubt about whether power can be cut safely, is a reason to leave the area and call from somewhere safe.
Contaminated water is the next concern. Sewage, drain backups, and floodwater can carry harmful contaminants, so keep people and pets away, avoid contact, and do not try to wade through it. Structure is the third: a ceiling that is sagging, bulging, or dripping is holding water and can come down without warning, so do not stand beneath it, and treat soaked floors and stairs as potentially slippery or weakened. When hazards like these are present, getting people to safety comes before anything else, and the cleanup waits until the area can be made safe.
