Flares and strobes

Signals that show up at night and across water, how to use them, and when to save them.

What you need

How

  1. Read the instructions on each flare at home, in daylight, before you ever need it.
  2. Wait until you can see or hear help coming. A flare no one sees is a flare wasted.
  3. Hold a handheld flare out at arm's length, downwind, and pointed away from the boat and from people.
  4. Fire an aerial flare up and slightly downwind, never straight overhead.
  5. Fire a second one a minute or two later so they can fix where you are.
  6. Turn the strobe on and leave it on once you need to be found at night. It runs for hours.

Do and don't

Do
  • Check the expiry date stamped on every flare before each season and replace the old ones.
  • Keep flares where you can reach them in a capsize, not buried in the bottom of a pack.
  • Keep your eyes off a burning handheld flare. It will blind your night vision.
Don't
  • Do not fire a flare as a test or a joke. It sets off a real search.
  • Do not fire flares in dry woods or near fuel.
  • Do not throw away old flares in the garbage. Ask where to return them.

Watch for

Danger
  • A handheld flare drips burning slag hot enough to burn through a boat, a jacket and skin.
  • An aerial flare fired straight up can come back down on you still burning.
  • Expired flares can fail to light or light badly, right when you need them.

Notes

A strobe on your life jacket costs little and is the one signal that keeps working after you are in the water.

Flares go with a whistle, a mirror and a beacon, not instead of them. See Getting found and Radios and beacons.

Canada sets rules for which flares a boat must carry. Check the current rules for your boat before you go.
