Distress Flares: Choosing Marine Safety Supplies in the UK

When you're responsible for a vessel, safety equipment is not something you want to think about only when an emergency happens. The right equipment needs to be selected, stored, checked and understood well before you leave the harbour.

Among the most important items are distress flares. These pyrotechnic signals can help attract attention over distance and indicate the location of a vessel in distress. However, choosing the right flares is not simply a matter of buying a standard pack and keeping it onboard. Your vessel type, operating area, intended use and applicable requirements all need to be considered.

For commercial vessel operators, fishing vessel owners, yacht owners and leisure boat users across the UK, understanding these differences can make marine safety planning much easier.

This guide explains what to consider when choosing distress flares, how different types work, and what other marine safety supplies should form part of your emergency-preparedness plan.

What Are Distress Flares and Why Do They Matter?

Distress flares are emergency signalling devices designed to attract attention and communicate that a vessel needs assistance. Traditional pyrotechnic distress signals are internationally recognised under the Collision Regulations and include rocket parachute flares, red hand flares and orange smoke signals.

They generally have two key purposes:

1. Attract attention over a distance

2. Help rescuers identify the vessel's location

That distinction is important. A long-range signal may help alert rescuers that something is wrong, while a shorter-range signal can help pinpoint your position once assistance is nearby.

This is why distress flares should be considered as part of a wider collection of marine safety supplies, rather than as a standalone emergency solution.

Types of Distress Flares Used in the UK

Not every flare performs the same function. Understanding the differences can help you determine what is appropriate for your vessel and operating conditions.

Red Parachute Rocket Flares

Red parachute rockets are designed for long-range distress signalling. They launch a bright red signal to a considerable height, making them more visible over distance during both daytime and nighttime conditions.

They can be particularly relevant to vessels operating further from shore or safe haven.

ADEC Marine's red parachute rocket, for example, is designed for day and night long-range distress signalling and reaches approximately 300 metres.

However, these signals must be handled carefully. They should not be fired when a helicopter is nearby because of the potential hazard created by the rocket.

Red Hand Flares

Red hand flares are intended for shorter-range distress signalling and can help pinpoint a vessel's position when rescuers are closer.

They are suitable for day or night use and are commonly included in appropriate marine safety equipment packages.

Because hand flares produce intense heat, crew members should understand how to handle them safely before an emergency occurs. ADEC Marine specifically advises keeping suitable gloves near the flare pack because red hand flares burn at extremely high temperatures.

Orange Smoke Signals

Orange smoke signals are primarily intended for daytime distress situations and location marking.

They can be particularly useful during rescue operations because the smoke creates a visible marker and can help indicate wind direction to rescue aircraft.

ADEC Marine's buoyant orange smoke signal is designed for daytime distress signalling on ships, lifeboats and liferafts and produces dense orange smoke for a minimum of three minutes.

How to Choose the Right Distress Flares for Your Vessel

There is no universal flare pack that is automatically suitable for every vessel.

When selecting distress flares, start with the circumstances in which your vessel operates.

1. Consider Your Operating Area

Distance from shore or a safe haven is an important consideration.

ADEC Marine categorises its flare packs around inshore, coastal and offshore operating areas. Its inshore pack contains red hand flares and orange hand smoke signals, while its coastal and offshore packs include additional long-range red parachute rockets and other signalling equipment.

The further your vessel operates from assistance, the more carefully your emergency signalling arrangements need to be considered.

2. Consider Day and Night Operations

Your operating schedule can also influence the type of equipment you need.

A vessel travelling at night may require signalling equipment suitable for low-light conditions. Fog and poor visibility can also change the way you approach emergency signalling.

The objective is to ensure that your distress flares can perform their intended function when visibility is limited and assistance needs to locate you.

3. Consider Your Vessel Type

Requirements can differ significantly between:

• Commercial vessels

• Fishing vessels

• Yachts

• Pleasure craft

• Charter boats

• Offshore vessels

The equipment carried by a small recreational vessel should not automatically be assumed to meet the requirements of a commercial or professionally operated vessel.

For that reason, operators should always establish the requirements applicable to their specific vessel and operation before purchasing marine safety supplies.

Distress Flares and UK Safety Requirements

Choosing distress flares is also a compliance consideration.

UK marine safety requirements can vary according to vessel type, size, operation and operating area. Commercial operators and fishing vessel owners may have requirements that differ from those applicable to recreational users.

The safest approach is to check the regulations and codes applicable to your vessel rather than relying on a generic online checklist.

You should consider:

• What type of vessel you operate

• Where the vessel operates

• Whether it is commercial or recreational

• What distance it normally travels from shore

• Whether it operates during the day, at night or both

• What signalling equipment is required

• Whether the equipment meets applicable approval standards

ADEC Marine supplies pyrotechnic equipment approved to relevant UK MCA, MED and SOLAS requirements, depending on the product and application.

Electronic signalling products can also be useful as part of a broader emergency strategy, but operators should not assume they automatically replace required pyrotechnic equipment. The applicable requirements for the vessel should always be checked first.

What Other Marine Safety Supplies Should You Carry?

Distress flares are only one part of an effective emergency plan.

The right marine safety supplies will depend on your vessel and operating conditions, but an emergency equipment review may include:

• Lifejackets

• Liferafts

• Lifebuoys

• EPIRBs and PLBs

• VHF communication equipment

• SARTs

• Emergency lighting

• Firefighting equipment

• First-aid supplies

• Safety harnesses and lines

• Man-overboard equipment

• Radar reflectors

• Emergency grab bags

ADEC Marine's marine safety range includes categories such as liferafts, lifejackets, marine electronics, medical stores, emergency lighting, firefighting equipment, safety lines, harnesses and pyrotechnics.

Rather than simply ticking boxes, think about the emergencies your crew could realistically face.

For example:

• Man overboard: flotation equipment, recovery equipment and communication.

• Fire: firefighting equipment, communication and evacuation equipment.

• Vessel distress: distress flares, radio communication and location equipment.

• Abandon ship: liferafts, lifejackets and emergency signalling equipment.

This approach makes your marine safety supplies strategy much more practical.

How Should Distress Flares Be Stored?

Correct storage is just as important as choosing the right distress flares.

Pyrotechnics should be kept somewhere that is:

• Dry

• Protected

• Easily accessible

• Away from unnecessary heat

• Known to the crew

ADEC Marine recommends appropriate watertight storage for pyrotechnic sets and offers dedicated watertight polybottles for this purpose.

Most importantly, don't store emergency equipment somewhere that becomes inaccessible during an emergency.

Crew members should know where the flares are kept and understand the basic instructions for their safe use.

What Should You Do With Expired Distress Flares?

This is an area where vessel owners need to be particularly careful.

Expired or damaged distress flares should not be used. They should also never be placed in household rubbish, garden waste or recycling bins.

UK government guidance states that anyone possessing marine flares remains responsible for them until they have been used or properly disposed of. HM Coastguard no longer provides the previous public-facing disposal service for private individuals, so an appropriate third-party disposal route should be arranged.

Never:

• Fire an expired flare as a test

• Throw flares into the sea

• Put them in household waste

• Put them in recycling

• Abandon them at a marina or harbour

• Transport them casually without checking the applicable requirements

Plan disposal when you review your marine safety supplies, rather than waiting until an old flare has already expired.

A Simple Distress Flare Checklist

Before heading out, vessel owners and operators can use this basic checklist:

• Identify your vessel's operating category

• Check the applicable safety requirements

• Confirm the appropriate types of distress flares

• Check the required quantities

• Check approval and certification

• Inspect expiry dates

• Look for signs of damage

• Confirm suitable storage

• Make sure the crew knows where flares are kept

• Review your wider marine safety supplies

• Arrange safe disposal for expired flares

• Review emergency procedures with the crew

This checklist is a practical starting point, but it should not replace the specific requirements applicable to your vessel.

Common Mistakes to Avoid When Choosing Marine Safety Supplies

Even experienced boat owners can overlook basic details when reviewing marine safety supplies.

Buying Based Only on Price

The cheapest option may not be the right option for your vessel, operating area or requirements.

Assuming One Pack Fits Every Vessel

Inshore, coastal and offshore operations can require different approaches to signalling equipment.

Ignoring Expiry Dates

Create a regular schedule for checking distress flares and other time-sensitive safety equipment.

Storing Equipment Incorrectly

Moisture, heat, damage and inaccessible storage can undermine the usefulness of emergency equipment.

Forgetting Crew Training

Equipment is only useful if the people onboard know where it is and understand the relevant emergency procedures.
