Why this matters
Official warning channels differ by location and hazard. Identify the agencies responsible for weather, public health, water, fire, policing and civil protection. Save their websites, alert services and radio frequencies before an incident.
Networks may be overloaded, damaged or deliberately manipulated. Use short messages, scheduled check-ins and an out-of-area contact. Separate confirmed facts from reports and record source, time and expiry for information that may change.
Before disruption
Prepare now
- Enable official alerts and learn the sounds, languages and actions used in your area.
- Write down household contacts, key services and one out-of-area contact.
- Keep a battery or hand-powered radio if it is useful in your country, and test reception.
- Agree a brief message format covering safety, location, needs and next contact time.
- Download essential information and maps for offline use without relying on one device.
When it is happening
Protect the next decision
- Check the issuing authority, location, timestamp and expiry before acting on or forwarding an alert.
- Prefer text messages or low-data methods when voice networks are congested.
- Correct important misinformation calmly with the verified source, not a screenshot without context.
- Set times for updates so people can conserve power and avoid constant distressing news.
Plan for real people
Access, care and inclusion
- Use captions, text, audio, visual signals and plain language according to people’s needs.
- Plan how people without smartphones, data, literacy or the local language will receive updates.
- Keep communication boards, hearing-device supplies and printed instructions accessible.
- Choose a trusted person to help interpret official information without taking away the individual’s choices.
Mental readiness
Protect morale and clear thinking
- Reliable contact reduces isolation, even when there is no new information.
- Limit repeated exposure to graphic footage and speculation while maintaining scheduled official checks.
- Record small confirmed improvements, such as a route opening or a neighbour found safe.
Common mistakes
What to avoid
- Forwarding unverified warnings, casualty figures, locations or requests for money.
- Sharing live locations or personal details more widely than safety requires.
- Relying on one social platform, one phone or one person for every update.
