0 Some sounds are made on purpose to warn you: sirens, car horns, smoke alarms and bike bells all say «pay attention now». 1 Other warning sounds come from nature and animals: thunder means lightning is near, and a dog's growl means «back off». 2 When you hear a warning sound, stop and work out where it comes from and what it means before you move. 3 Example: a smoke alarm beeping loudly at night means get out at once — not hide, not look for toys, not finish your game. 4 A family in Pennsylvania ignored a chirping smoke alarm with a flat battery for weeks; when a fire started at night the alarm stayed silent, and they woke late to a house full of smoke. 5 A boy in Perth wore noise-cancelling headphones while walking behind a reversing truck; he did not hear its beeping and the driver stopped just in time. 6 A siren means an emergency vehicle, such as an ambulance, a fire engine or a police car, is coming. 7 When you hear a siren near a road, stay on the pavement or sidewalk and wait until the vehicle has passed. 8 Drivers pull over to let emergency vehicles through, so traffic at a crossing can change suddenly. 9 A car horn is a warning that a driver thinks someone may be in danger. 10 A loud, repeating smoke alarm means there may be a fire: get out and stay out. 11 A single short chirp every minute or so from a smoke alarm usually means its battery is low. 12 A carbon monoxide alarm warns of a gas you cannot see or smell; when it sounds, everyone should go outside into fresh air. 13 A dog that growls, shows its teeth or goes stiff is warning you to stay away. 14 If a dog growls at you, stand still like a tree, do not stare into its eyes, and back away slowly once it calms. 15 If you can hear thunder, you are close enough to be struck by lightning, so get out of the water and go inside a building. 16 In parts of the USA, outdoor sirens warn of tornadoes; when they sound, go inside to the lowest floor, away from windows. 17 In a fire, call the emergency number from outside: 911 in the USA and Canada, 999 in the UK and Ireland, 000 in Australia, 111 in New Zealand. 18 A smoke alarm that does not work cannot wake you, and most deadly home fires happen at night while people sleep. 19 Headphones can block the warning sounds of cars, bikes, horns and alarms. ← previous Eyes up: noticing your surroundingsnext → Smells that warn↑ back to Everyday This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/everyday/12-sounds-that-warn/
