Pyrotechnics & Distress Signals
Supply and replacement of SOLAS rocket parachute flares, hand flares, smoke signals and line-throwing rockets, with expiry tracking and landing of expired pyrotechnics.
Overview
Marine pyrotechnics and distress signals
Marine pyrotechnics and distress signals are the visual means by which a ship or survival craft attracts attention in an emergency. SOLAS ships carry rocket parachute flares on the bridge, hand flares and buoyant smoke signals in lifeboats and liferafts, self-activating smoke signals on lifebuoys, and a line-throwing appliance. Every one of these items has a limited service life, and expired signals must be replaced and landed for safe disposal.
Because pyrotechnics are explosives, supply and disposal are more complicated than for other safety equipment. Delivery must respect dangerous goods rules, port regulations and customs, and expired items cannot simply be thrown away. vslSafety coordinates the supply of approved replacements and the landing of time-expired pyrotechnics through providers at the vessel’s port.
Regulatory requirements and standards
Carriage requirements are set by SOLAS chapter III. Regulation III/6 requires not less than 12 rocket parachute flares, stowed on or near the navigating bridge. Regulation III/7 requires lifebuoy self-activating smoke signals, and regulation III/18 requires a line-throwing appliance. The International Life-Saving Appliance (LSA) Code sets the performance standards in chapter III for rocket parachute flares, hand flares and buoyant smoke signals, and in section 7.1 for line-throwing appliances.
The LSA Code sets clear minimum performance. A rocket parachute flare must reach at least 300 m and burn bright red for not less than 40 seconds. A hand flare must burn for at least one minute. A buoyant smoke signal must emit smoke for at least three minutes in calm water, and a lifebuoy self-activating smoke signal for at least 15 minutes. A line-throwing appliance must include at least four projectiles, each capable of carrying the line at least 230 m in calm weather.
Liferafts and lifeboats equipped to the full SOLAS standard carry four rocket parachute flares, six hand flares and two buoyant smoke signals. Liferafts with a SOLAS B pack, permitted by the Administration for some passenger ships on short international voyages, carry half of these quantities. The LSA Code requires the Administration to determine the period of acceptability of appliances that deteriorate with age, and requires them to be marked with a means of determining their age or replacement date. In practice, pyrotechnics carry an expiry date set by the maker, commonly three or four years from manufacture. Replacements must be of a type approved by or on behalf of the flag Administration, for example with MED wheel mark or USCG approval.

What the service includes
- Review of the pyrotechnics inventory, expiry dates and planned replacements
- Supply of approved rocket parachute flares, hand flares and buoyant smoke signals
- Supply of lifebuoy self-activating light and smoke signals and line-throwing appliances
- Replacement of pyrotechnics in lifeboat equipment, coordinated with lifeboat servicing
- Delivery under dangerous goods rules, with port and customs formalities handled by the provider
- Collection and landing of time-expired pyrotechnics for disposal through licensed channels, where available at the port
- Updated inventory and delivery documents for the ship’s records
Equipment types covered
The service covers SOLAS-approved rocket parachute flares, red hand flares, orange buoyant smoke signals, combined lifebuoy light and smoke signals, pistol-fired and self-contained line-throwing appliances, and replacement rockets and lines. Common makes seen on ships include Pains Wessex, Hansson Pyrotech, Ikaros, Comet and Nanjing Ningqiao, among others. Replacement should match the approved type expected by the flag or be accepted as equivalent.
Common defects and PSC deficiencies
- Rocket parachute flares on the bridge past their expiry date, or fewer than 12 on board
- Lifeboat pyrotechnics expired or missing from the equipment list
- Lifebuoy self-activating smoke signals expired, damaged or not properly attached
- Line-throwing appliance rockets expired, or lines missing
- Expired pyrotechnics mixed with valid stock instead of being segregated and marked
- Pyrotechnics without evidence of approval, or with damaged casings or moisture ingress
Certificates and documents you receive
- Delivery note listing each item, quantity, lot number and expiry date
- Type approval or certificate of conformity for the supplied signals
- Dangerous goods documentation for delivery
- Receipt or disposal note for landed expired pyrotechnics, where provided by the disposal route
How to prepare the vessel
Count pyrotechnics on the bridge, in each lifeboat and at the lifebuoys, and record expiry dates. Keep expired items segregated in a marked container away from electrical sources and ready for landing. Confirm with the agent whether the port permits delivery of explosives at the berth or only at anchorage, and whether a permit is needed. Liferaft pyrotechnics are normally renewed during liferaft servicing, and lifeboat pyrotechnics can be replaced during lifeboat inspection and servicing.
Information needed for a quotation
- Vessel name, IMO number, flag and class
- Port, berth or anchorage, ETA and ETD, and the ship’s agent
- Item types and quantities needed, with required approval (for example MED, USCG)
- Preferred maker, if any, to match existing stock
- Quantity and type of expired pyrotechnics to be landed
- Whether pyrotechnics must be fitted in lifeboats or only delivered to the bridge
vslSafety then coordinates a suitable provider at the vessel’s port and confirms availability, lead time and delivery arrangements.
Frequently asked questions
How long are marine distress flares valid?
SOLAS pyrotechnics carry an expiry date set by the maker and accepted by the approving Administration, commonly three or four years from the date of manufacture. The LSA Code requires appliances that deteriorate with age to be marked with a means of determining their age or replacement date. Flares must be replaced before that date.
How many rocket parachute flares must a SOLAS ship carry?
SOLAS regulation III/6 requires not less than 12 rocket parachute flares, stowed on or near the navigating bridge. This is separate from the four rocket parachute flares carried in each lifeboat and SOLAS A pack liferaft. They must comply with the LSA Code, reaching at least 300 m and burning red for at least 40 seconds.
How do ships dispose of expired flares?
Expired pyrotechnics should be kept segregated and landed ashore for disposal through a licensed route. Arrangements depend entirely on national law: some countries operate collection points or licensed contractors, while in others disposal options are limited and only a supplier can take back time-expired stock. Firing expired flares at sea is not an acceptable disposal method and can trigger false distress alerts. Ask for disposal to be quoted with the replacement supply.
Can pyrotechnics be delivered at any port?
Not always. Pyrotechnics are dangerous goods, and ports and terminals may restrict their delivery, require permits, or allow delivery only at anchorage. Lead times can be longer than for other safety equipment because of transport restrictions. Early notice of the vessel’s schedule and required quantities gives the provider time to arrange stock and permits.
Are liferaft flares replaced at the annual liferaft service?
Yes, in most cases. The approved liferaft service station checks the equipment pack and replaces pyrotechnics and other items that have expired or will expire before the next service. The replacement is recorded on the service certificate. Lifeboat pyrotechnics are the ship’s responsibility and are checked during routine inspections.
