Guide to Flare Usage and Safety

Orion 12-Gauge LauncherAs boaters, we all understand the necessity of having marine flares on board – but understanding how to use them in an emergency just may save your life. Below we answer some basic questions on USCG requirements and the safe usage and disposal of flares.

What are the USCG Requirements?

By law, a visual distress signal must be carried “on all boats that are operated on the high seas, coastal waters (including the Great Lakes), the territorial seas, and all waters directly connected to the Great Lakes or the territorial seas up to a point where the waters are less than two miles wide.” The following vessels are not required to carry day signals, but must carry night signals when operating from sunset to sunrise:

If required, you must have a minimum of three signals for both day and night usage and they must be approved by the U.S. Coast Guard. Since some signals meet both day and night use requirements (see below), having three of this type would mean you are legal. That said, most experts recommend that you have a minimum of six to make sure you have enough to handle a real emergency.

What Kind of Flare Should I Use?

As you can imagine – which flare you choose should be dictated by what you are trying to do (attract attention or pinpoint your location), and with how far away help may be located.

  1. First off – always stay with your boat if it is safe to do so. A boat is much easier to spot than a swimmer, so don't jump ship unless you are in immediate danger.
  2. Conserve your aerial signals until you are reasonably sure of being sighted. Wait until you see or hear a vessel or aircraft before using "one-time" signals.
  3. Once you've sighted help, the U.S. Coast Guard recommends that you fire two aerial flares – one immediately after the other – so rescuers can confirm the sighting and the direction of the signal. If using a parachute flare, one is fine as it has an adequate burn time to confirm sighting and position.
  4. Once you aerial flare has been seen, you must make sure your rescuer can pinpoint your location by using hand-held flares. The surface-to-surface sighting range on water is approximately 3 to 5 miles, depending on boat elevation. If a rescuer is 5 miles away and running at 20 miles per hour, it will take 15 minutes to reach you. Therefore, you should have a minimum of 12 minutes of signal burn time for a strong homing signal. Hand-held flares last approximately 3 minutes – so we recommend you have 6 to be on the safe side as not all boats travel that fast.
  5. Make sure to familiarize yourself with your signals before you leave shore. Time is important in any emergency and it shouldn't be spent reading instructions.

How Do I Store My Flares?

While flares are classified as flammable, they are generally safe and stable if stored correctly. There is no threat of mass explosion, nor is there any threat of an individual flare exploding. They should be stored in a cool, dry place away from excessive heat (above 167 degrees F), and away from sparks or flames. The normal recommended storage temperatures are 40 degrees to 90 degrees F. Do not expose flares to water for periods of longer than 10 minutes.

What Do I Do With My Expired Flares?

Marine flares expire 42 months after the manufacture date in accordance with the Coast Guard requirements, so check the expiration dates on your flares and signals as shown below. If they have expired or will expire during the boating season, you must replace's the law!

Orion Flare Expiration Date Locations

To dispose of expired flares, Orion recommends the following methods:

For disposal in the Seattle area

King County residents may dispose of their expired flares at four recycling locations – found here. They will accept 10 ordinances per person. Kitsap County Sherriff will accept all flares which are individual (non-business). Other local counties have policies which vary by the situation, so please contact local law enforcement for further information.

We hope you've found this Navigator on flare usage and safety helpful, but if you have any additional questions, please don't hesitate to contact our safety experts at (800) 426-6930. Fisheries Supply carries a wide range of marine flares - so if your flares have expired, replace them right away!
