Safely Disposing of Expired Flares: A Boater’s Guide

By: Safety

Marine flares are crucial for boater safety, used as a tool to signal for help when a vessel is in distress. However, these pyrotechnic devices come with a shelf life, typically expiring 42 months after their manufacture date. However, disposing of expired flares may not be as straightforward as one might hope, and improper disposal can lead to severe consequences, both legally and environmentally.

One recurring question in discussions is whether expired flares are dangerous or simply less reliable. As one forum contributor aptly pointed out, “The way it was put to me in my Yachtmaster training is – if you are letting off flares, you have significant problems. Now, imagine that an out-of-date flare exploded and blew your right hand off – your problems have now significantly escalated!” Another contributor raised concerns about insurers possibly denying claims for injuries caused by expired pyrotechnics, underscoring the importance of their use-by date.

Expired flares are not just less reliable – they can be dangerous and should always be handled with caution as explosive devices. Over time, as previously mentioned, the chemicals in flares can become unstable, increasing the risk of accidental ignition or malfunction. Stories of flares exploding or misfiring due to age are not uncommon, emphasizing the importance of handling these devices with care. Additionally, using expired flares in non-emergency situations can lead to significant penalties. Just ask the two Rhode Island men who were fined $10,000 for discharging flares as part of a wedding celebration, which resulted in an expensive search-and-rescue operation by the U.S. Coast Guard.


· Fire Department Assistance

Many local fire departments may accept expired flares for disposal in their burn units. It is advisable to contact your local fire department’s non-emergency number to inquire if they offer this service.

· Boating Organizations and Training Programs

Some boating education groups and safety organizations use expired flares for training purposes. While this option is becoming less common, it’s worth checking with local boating groups or the U.S. Coast Guard Auxiliary.

· Household Hazardous Waste Facilities

Contact your local household hazardous waste management facility to inquire if they accept marine flares. These facilities are equipped to handle and dispose of hazardous materials safely.

· Contact Your Local American Sailing School

Contacting your local American Sailing School can be another avenue worth exploring for disposing of expired flares. These schools often have connections within the boating community as well as local Yacht Associations and may be aware of local programs or recommendations for flare disposal. They might also have insights into alternative methods or organizations that could assist with proper disposal. While these schools may not directly handle disposal, they could provide valuable guidance or direct you to appropriate resources.


Another method we’ve seen suggested across many online forums and groups is the process of soaking flares in water until they break down. However, marine flares contain perchlorate, a pollutant and possible carcinogen, and their waterproof shells prevent effective breakdown, leaving hazardous chemicals intact. Therefore deeming this solution environmentally unsound and a method we would not recommend.

Alternatives to Pyrotechnic Flares

Given the challenges disposing of expired flares present, another solution may be switching to electronic flares. LED (light-emitting diode) flares boast to be a safer and more environmentally friendly alternative. They never expire, provide brighter and longer-lasting signals, and eliminate the disposal problem associated with traditional pyrotechnic flares.


Efforts are ongoing to create better disposal solutions for expired flares. For example, the Sea Tow Foundation has recently shared the following video and a helpful article HERE with a list of known locations that will accept the submission of expired flares.

Disposing of expired flares responsibly is crucial for safety, legal compliance, and environmental protection. We encourage all boaters explore their local disposal options, consider transitioning to electronic flares, and stay updated on new disposal programs. By taking these steps, boaters can help ensure their own safety and that of the broader maritime community.
