Another kind of rocket flare is fired from a specially designed flare gun or Very pistol. These flares are aluminum tubes about 3cm (just over an inch) in diameter and 30cm (12inches) or so long. When they're fired, they shoot rapidly to a height of about 300m (1000ft).
The oxidizer is the oxygen in the surrounding atmosphere. These two ingredients can sustain a candle flame. The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch.
A flare gun is just a device that delivers a flare with ease. Using one for self defense is generally not a good idea. Especially in a car. Flares are made to burn for a long time, and in extreme situations.
Specifically, it states, “The expiration date must be not more than 42 months from the date of manufacture.” This rule exists to make it harder for you to have bad flares aboard — not because they can't last more than 42 months, but because the Coast Guard knows many boaters can't be trusted to inspect them regularly.

Leaving them in a bag can actually help drive moisture into the flares 'cause of the humidity and the sealed environment. I'd suggest taking them out so they air out after each use, and only putting them in bags when you're on the water. do most inexpensive marine flares work at all.
Sure, Glocks, grenades, and M80s all work while submerged, but what about a good ol' 12 gauge flare gun? The bad news is (spoiler alert) they can't make it happen unless the frame is above water, and then the aerial flare, which needs oxygen, doesn't really do anything.
Some emergency flares are rated waterproof and can be ignited in the rain, or in rough seas, and even underwater. All flares, however, are considered water-resistant. Flares are an essential survival tool and a required one for boats more than 50 miles from shore.
Red hand flare. 5 to 10 nautical miles. Are red in colour and can be used during the day.
Pyrotechnic devices come with an expiration date, which is 42 months from the date of manufacture. To meet carriage requirements, you must have at least three un-expired flares aboard. You may carry expired flares as back up, but they will not count towards the legal requirement.
Flares produce their light through the combustion of a pyrotechnic composition. The ingredients are varied, but often based on strontium nitrate, potassium nitrate, or potassium perchlorate and mixed with a fuel such as charcoal, sulfur, sawdust, aluminium, magnesium, or a suitable polymeric resin.
A hand flare is a small cylindrical stick which when activated, produces an intense red smoke or light without an explosion. Should be held out leeward when activated. Can be used by the day as well as night.
Throwing flares in your household trash can cause a dangerous situation and setting off old flares can result in false distress reports.

The number and type of distress flares required on board a pleasure boat depends on the length of the vessel, the type of vessel, and the area of operation.
There is nothing wrong with shooting a flare if you are in distress or in need of assistance. Often a Good Samaritan will come to assist when a flare is fired. Other boaters may have seen the flare and called the Coast Guard, so it is important you let the Coast Guard know via VHF radio or phone that you fired a flare.
A high intensity white light flashed at regular intervals of 50 to 70 times per minute; A signal consisting of a square flag with a ball or anything resembling a ball.
A distress signal, also known as a distress call, is an internationally recognized means for obtaining help. Distress signals are communicated by transmitting radio signals, displaying a visually observable item or illumination, or making a sound audible from a distance.
An other common feature of distress flares is that they are valid four years from the date of manufacture, which is stamped on every flare. Ask the manufacturer how to dispose of your outdated flares. Visual signals are not required for boats up to 6m and for human-powered boats.
If the vessel in distress is taking on water, request that the passengers don PFD's, and then transfer them to your boat. See if there's something you can do to keep the vessel afloat. If you can, radio the Coast Guard or local marine patrol and tell them what you're up to.
Even high flying SOLAS parachute flares of the 1,000 feet variety with burn times of approximately 40 seconds have limits. Without getting into things like “apparent horizon” and “refraction” – at their peak they can be seen 36-37 miles away at the most, and then only for a brief moment.
Red Meteor (day and night) Orange Smoke Signal (hand-held/day only) Floating Orange Smoke Signal (day only) Orange Signal Flag (day only) Electric Distress Light (night only)
For boats under 16' in length: Distress signals are only required when operating between sunset and sunrise. If operating at night, one electric distress light or three combination day/night red flares are required.
Whilst distress flares are red in colour, white flares are also available and can be effectively used to mark a position or illuminate a large area at night. Flares should always be taken with you to a liferaft but most importantly, make sure you know how to use your flares before you go to sea.
Flares Pyrotechnics fall into three classifications: floating, handheld and aerial (meteor and parachute). Floating and handheld red-smoke flares are approved for daytime use only. Red flares, whether handheld or aerial, are for daytime and nighttime uses.
One hand-held orange smoke signal (day), two floating orange smoke signals (day) and one electric light (night only).

You can dispose of out-of-date flares at temporary collection points located at boat ramps along the NSW coast. The collection program begins on Wednesday 4 January 2017. Most flares have a use-by date of 3 years and must be replaced before their expiry date, or penalties apply.
