Understanding the Latest SOLAS Requirements for Maritime Radio Communications
The maritime industry operates under some of the world's most stringent safety regulations, and communication equipment plays a critical role in protecting both vessels and crew members during emergencies.
The International Maritime Organization (IMO), through its Maritime Safety Committee, introduced amendments to the Safety of Life at Sea (SOLAS) Convention that affect onboard two-way radio requirements.
For many vessel operators, these changes introduced new obligations regarding the type and quantity of portable radios carried onboard, particularly for emergency response and firefighting teams.
What Are the Updated SOLAS Requirements?
The SOLAS amendment requires ships to carry a minimum number of intrinsically safe portable two-way radios specifically intended for use by onboard fire parties.
The regulation states:
"For ships constructed on or after 1 July 2014, a minimum of two two-way portable radiotelephone apparatus for each fire party for fire-fighter communication shall be carried on board."
The radios must be either:
- Explosion-proof, or
- Intrinsically safe (ATEX certified)
For vessels constructed before 1 July 2014, compliance was required by the first survey following 1 July 2018.
Why Were These Changes Introduced?
During emergency situations such as onboard fires, effective communication between firefighters, officers and emergency response teams is essential.
Traditional communication methods can become unreliable or impractical in hazardous conditions. Portable two-way radios provide a dependable means of communication, allowing fire parties to coordinate activities, report conditions and receive instructions quickly.
However, not all radios are suitable for use in potentially explosive environments.
This is why SOLAS specifically requires intrinsically safe or explosion-proof equipment.
What Is an Intrinsically Safe (ATEX) Radio?
An intrinsically safe radio, often referred to as an ATEX radio, is specially designed for use in hazardous environments where flammable gases, vapours, dust or combustible materials may be present.
Standard electronic devices can potentially create:
- Electrical sparks
- Excessive heat
- Static discharge
Any of these could become a source of ignition in a dangerous atmosphere.
ATEX-certified radios are engineered to eliminate or significantly reduce these risks through strict design, manufacturing and testing standards.
This makes them suitable for use in:
- Marine vessels
- Oil and gas facilities
- Petrochemical plants
- Fuel storage facilities
- Chemical processing sites
- Industrial environments with explosive atmospheres
How Many Radios Does Your Vessel Need?
One area that occasionally causes confusion is the relationship between firefighter outfits and fire party requirements.
The SOLAS guidance makes it clear that the radios are allocated to fire parties rather than individual firefighter outfits.
This means the total number of radios required depends upon:
- The number of fire parties detailed on the vessel's Muster List
- The vessel's emergency response procedures
- Crew organisation during emergency operations
Ship operators should therefore review their emergency plans carefully to ensure sufficient compliant radios are available.
Benefits Beyond Regulatory Compliance
While compliance is essential, intrinsically safe radios also provide several operational advantages.
These include:
- Improved crew safety
- Reliable emergency communications
- Enhanced coordination during incidents
- Durable construction for harsh marine environments
- Resistance to moisture, dust and impact
- Greater confidence during emergency response situations
Many modern ATEX radios also include advanced digital features such as:
- Emergency alert buttons
- Lone Worker monitoring
- GPS location services
- Noise-cancelling audio
- Text messaging capability
Recommended ATEX Radio Solutions
Professional maritime operators often select purpose-built digital radios designed specifically for hazardous environments.
Popular options include ATEX-certified Motorola radios, which combine rugged construction, advanced communication features and compliance with international safety standards.
Choosing the correct model depends on:
- Vessel type
- Operating environment
- Crew size
- Emergency response requirements
- Existing communication infrastructure
