Immediate rule

For an immediate threat, call the local emergency number. For household check-ins, use a short text message and a written meeting plan; never delay evacuation to charge a phone.

Five practical skills

A concise, repeatable field sequence. Read these before an emergency and follow official incident instructions when they differ.

Skill 1 of 5

Create a contact and regrouping plan

Rule: A simple printed plan works when apps and mobile data fail.
  1. Choose one trusted out-of-area contact who can relay status among household members.
  2. Write emergency numbers, medical contacts, building details and two meeting places on waterproof paper.
  3. Agree on a short check-in message format: name, location, condition and intended next step.

Skill 2 of 5

Make battery power last

Rule: Save charge before it reaches a critical level.
  1. Charge a power bank ahead of travel and check it regularly. Carry the correct cables and a small plug-in charger.
  2. Reduce brightness, switch to low-power mode and disable unnecessary background downloads, streaming and location sharing.
  3. Use airplane mode only when you do not need alerts or calls; switch connectivity back on to check warnings and send updates.

Skill 3 of 5

Communicate briefly and precisely

Rule: Short texts often work with less bandwidth than long calls.
  1. Try emergency calling first for an active life-threatening incident. If a call fails, use officially supported emergency text services only where available.
  2. For routine check-ins, send one concise SMS with your last known location and condition; avoid flooding the network with repeated calls.
  3. Share precise location using an address, landmark, road marker or coordinate pair, plus the time the position was measured.

Skill 4 of 5

Use backups for local information

Rule: Radio and paper can outlast a data connection.
  1. Carry a battery- or hand-crank-powered radio tuned to locally available emergency broadcasts.
  2. Save offline maps and learn to read a paper map before leaving; mobile GPS may work without cellular data, but maps may not load.
  3. Use local government alerts and official channels rather than unverified social-media rumors.

Skill 5 of 5

Signal and wait for help safely

Rule: Choose a stable, visible position and keep a reserve for rescue contact.
  1. If lost, avoid random movement once your location can be reported accurately, unless remaining there is dangerous.
  2. If appropriate, use a whistle or bright marker to draw attention, while avoiding fire or smoke signals in hazardous conditions.
  3. Keep your phone accessible with a small reserve of battery and follow rescue service instructions exactly.
