Hand Flares A Critical Visual Distress Signal at Sea
In the vast expanse of the ocean, where visibility is key to rescue, a Hand Flare is one of the most immediate and recognizable distress signals available to a mariner. As a pyrotechnic device designed to be held in the hand, it produces a brilliant red flame and, often, smoke, making it an indispensable tool for pinpointing a vessel’s location during an emergency, especially at night. This guide explores the types, regulations, safe usage, and vital maintenance requirements governing these powerful pyrotechnic signals.
What is a Hand Flare?
A hand flare is a handheld pyrotechnic distress signal that burns for approximately 60 seconds with a vivid red flame of high intensity (typically over 15,000 candela). Its primary purposes are
Signaling for Help To alert other vessels or aircraft to your position in an emergency situation, such as man-overboard, impending collision, or when abandoning ship.
Pinpointing Location The bright flame is highly visible against a dark sea and sky, allowing rescuers to precisely locate a life raft, survival craft, or persons in the water, particularly during nighttime or in low-light conditions.
It is a short-range signal, effective for vessels and aircraft within a visible range of several miles. It is always used in conjunction with other signals like rocket parachute flares (long-range) and orange smoke signals (daytime).
Hand Flares and SOLAS/IMO Regulations
The carriage and specifications of pyrotechnic distress signals, including hand flares, are strictly governed by the International Convention for the Safety of Life at Sea (SOLAS), Chapter III, Regulation 6, and must comply with the testing requirements of the IMO’s International Life-Saving Appliance (LSA) Code.
Key regulatory points include
Carriage Requirements The number of pyrotechnics required depends on the type of vessel. For example, all SOLAS vessels must carry a minimum number of rockets and flares in their survival craft. Cargo ships typically must have 12 rocket parachute flares, while passenger ships must have 12 rocket parachute flares and 12 hand flares. The exact requirements are detailed in the SOLAS tables under Chapter III.
Performance Standards The LSA Code specifies rigorous criteria that every certified hand flare must meet
Burn Time Must burn for not less than 60 seconds.
Luminous Intensity Must burn with a bright red colour of at least 15,000 candela.
Burn Characteristics It must not burn violently, splutter, or show any danger of burning through its casing during operation. It must not be extinguished by waves or wind during its specified burn time.
Water Resistance It must continue to burn for at least 10 seconds when immersed 100 mm under water.
Marking Each unit must be clearly marked with its date of manufacture, expiry date, and clear instructions for use.
Types of Hand Flares
While the core function is consistent, hand flares are generally a single type of device. The primary variation lies in their packaging and activation mechanism, which are designed to be intuitive and safe
Pull-Cap Ignition The most common type. A removable cap at the top of the flare protects the ignition striker. To activate, the user removes the cap, revealing a rough striker surface. They then firmly pull a toggle or ring at the base of the flare downwards against this striker to create friction and ignite the flare.
Integrated Striker Some designs have a striker button or pad directly on the body of the flare.
It is crucial that all crew members are familiar with the specific type carried on their vessel through regular drills using expired (dummy) units.
Safe Handling and Usage Procedure
Hand flares are powerful pyrotechnics and must be treated with extreme respect. Incorrect handling can lead to severe burns or fire.
How to Operate a Hand Flare
Remove from Packaging Take the flare out of its waterproof packaging.
Read Instructions Quickly check the printed instructions on the flare itself.
Assume a Safe Posture Hold the flare firmly downwind at arm’s length, ensuring the ignition end is pointing away from your body, face, and other people. Crouch low in a life raft or brace yourself on a stable deck.
Activate Remove the protective cap and expose the ignition striker. Firmly pull the ignition toggle straight downwards in a sharp, swift motion against the striker.
Hold Steady Once ignited, hold the flare steadily over the leeward side (downwind side) of the vessel or life raft. Do not wave it around.
Dispose After burning out (approx. 1 minute), the flare will be extremely hot. Carefully drop the metal casing into the water, ensuring it is fully cooled to avoid damaging an inflatable life raft.
WARNING Never look directly into the burning flare as it can cause temporary or permanent blindness.
The Critical Importance of Inspection, Maintenance, and Certification
Due to their chemical nature, pyrotechnics have a strict shelf life and are highly susceptible to degradation from moisture. A malfunctioning flare can fail to ignite, burn incorrectly, or pose a serious safety hazard.
Shelf Life Hand flares typically have a shelf life of 42 months (3.5 years) from the date of manufacture. This expiration date is stamped on each individual unit and its packaging.
Inspection Flares must be visually inspected regularly (as part of monthly LSA checks) for signs of damage, corrosion, or leaking packaging. Any flare with a compromised seal or visible damage must be isolated and replaced immediately.
Storage They must be stored in a waterproof, durable container clearly marked “DISTRESS FLARES,” which is kept in a readily accessible location on the bridge or in the life raft.
Most importantly, expired or damaged flares must be replaced promptly and disposed of in accordance with local and international regulations for hazardous materials. They cannot be serviced or refurbished.
Frequently Asked Questions (FAQ)
Q1 What is the difference between a hand flare and a rocket parachute flare?
A A hand flare is a short-range signal held in the hand, effective for about 3-5 nautical miles. A rocket parachute flare is launched into the air, reaches a high altitude (300+ meters), and then descends slowly under a parachute, making it visible from up to 30-40 nautical away. It is a long-range signal.
Q2 Can hand flares be used in any weather?
A They are designed to be weather-resistant and should function in rain, wind, and sea spray. However, extremely severe conditions may affect their performance. Always attempt to shield the ignition process from direct waves.
Q3 What should I do if a flare fails to ignite?
A If the first attempt fails, you may try one more sharp, firm pull. If it still fails, assume it is defective. Dispose of it overboard carefully to avoid confusion with an active signal, and use a new flare.
Q4 Who is authorized to use hand flares?
A They should only be used in a genuine emergency situation where there is a grave and imminent danger to life or the vessel. Their use is governed by international law, and false signaling is a serious offense.
Q5 How should expired flares be disposed of?
A Expired flares are classified as hazardous waste. They must not be thrown overboard or in regular trash. Vessel operators must contact a licensed hazardous waste disposal company or port authority for correct and legal disposal procedures.
