Water: make it safe to drink
DRAFT: not yet checked against the sources. When in doubt, ask a doctor or rescuers.
First minutes
- Cloudy water: let it settle, strain through thick clean cloth.
- Boil: rolling boil for 1 minute (above 2000 m / 6500 ft: 3 minutes).
- Cool in a closed clean container. Do not pour into a dirty one.
- No fire: water filter or purification tablets strictly per the package.
- Store closed, in clean containers. Sip, and drink more in heat.
- Water is short: drinking for you and children first, then cooking, then washing hands.
Do NOT
- × Drink seawater or urine: it dehydrates faster.
- × Drink flood or swamp water untreated.
- × Assume boiling removes chemicals or fuel: it does not. Water smelling of chemicals or with a rainbow film is unfit.
- × Drink from a bucket also used to wash hands or dishes.
