Emergency Signals and Distress Communication Course
This course gives you the essential skills to act effectively when a situation turns critical. You will learn to recognize and use visual and sound emergency signals, to transmit a distress message correctly by radio and DSC, to apply standard IMO phraseology and alternative communication methods, to use and maintain flares, portable radios and alerting devices, and to respond quickly and accurately so that you protect your own safety and that of others.

What is the Emergency Signals and Distress Communication Course?
This short course prepares you to interpret and use every alerting and communication resource available in an emergency. You will study visual and sound signals, lights and hand signals, the priority of distress, urgency and safety messages, DSC alerts and radiotelephony, satellite alerting devices, the use and upkeep of pyrotechnics and portable radios, structured decision-making with the OODA loop, and the regulations that govern emergency signaling and communication in your sector.
What sets this course apart: a practical approach built around simulated emergency scenarios that sharpen your response time and decision-making; constant use of standard phraseology so that your messages are understood by crew, authorities and rescue services; attention to the human, technical and environmental factors that make communication fail; up-to-date guides and checklists you can apply straight away; and a final project in which you design and evaluate an emergency signaling and communication plan.
Program highlights
- Visual and sound signals: lights, flares, smoke, whistles, horns, mirrors and hand signals.
- Distress, urgency and safety messages with clear priorities and standard IMO phraseology.
- DSC alerts and radiotelephony: what to transmit, on which channel and in what order.
- Alerting equipment: flares, portable radios and satellite devices, with their use and maintenance.
- Decision-making under pressure with the OODA loop adapted to emergencies.
- Final project: an emergency signaling and communication plan tested in a drill.
Syllabus of the Emergency Signals and Distress Communication Course
5 modules. Select a module to see its content.
Fundamentals of emergency signaling: visual, sound and hand signals in critical situations
- 1.1. Why signals matter: detection, identification and confirmation of intentions in an emergency
- 1.2. Visual signals: lights, flares, orange smoke, signal mirrors, dye markers and arm signals
- 1.3. Sound signals: whistles, horns, bells and general alarm patterns on board and ashore
- 1.4. Hand and non-verbal signals for evacuation and team coordination when voice fails
- 1.5. Interpreting signals from others: recognizing a call for help and avoiding misunderstandings
Emergency communication protocols: radiotelephony, DSC, standard phraseology and priorities
- 2.1. Order of priority: distress, urgency and safety messages and when each one applies
- 2.2. Structure of a distress message: identity, position, nature of the emergency and assistance required
- 2.3. DSC alerts and follow-up by radiotelephony on the designated channels
- 2.4. Standard IMO phraseology and clear, concise language adapted to crew, authorities and rescue services
- 2.5. Alternative communication methods: satellite systems, mobile phones and visual relays when radio is unavailable
Signaling and communication equipment: use, inspection and maintenance
- 3.1. Pyrotechnics: hand flares, parachute rockets and smoke signals, safe handling and storage
- 3.2. Portable and fixed radios: operation, batteries, range and basic troubleshooting
- 3.3. Satellite alerting and locating devices: activation, registration and false-alert prevention
- 3.4. Inspection routines, expiry dates, records and renewal of signaling equipment
- 3.5. Choosing the right equipment for each environment: sea, coast, industry and outdoor activities
Decision-making, human factors and the regulatory framework for emergency communication
- 4.1. The OODA loop (observe, orient, decide, act) applied to emergency situations
- 4.2. Human factors: stress, fatigue, noise and language barriers that degrade communication
- 4.3. Technological and environmental factors: coverage, weather, visibility and equipment failure
- 4.4. Current regulations and standards on emergency signals and communication in each sector
- 4.5. Roles and responsibilities: who signals, who communicates and who coordinates the response
Realistic drills and final project: an emergency signaling and communication plan
- 5.1. Design of emergency scenarios: man overboard, fire, evacuation, people lost or adrift
- 5.2. Running drills: signals, distress messages, coordination and response times
- 5.3. Evaluating performance: what worked, communication failures and their causes
- 5.4. Improvement proposals covering procedures, equipment, training and the human factor
- 5.5. Final project: drafting, testing and reviewing an integrated signaling and communication plan
Duration and format of the Emergency Signals and Distress Communication Course
It is 300 hours. Tell us how many you can study each week and we will tell you when you will really finish.
This is the pace at which most students finish. It fits well with the installment plan.

Questions about the Emergency Signals and Distress Communication Course
SOS is the best-known distress signal, but there are others: the spoken word "Mayday", a DSC distress alert, red flares, orange smoke and slowly raising and lowering outstretched arms. The course explains when and how to use each one.
Visual and sound signals such as flares, smoke, a signal mirror, a whistle or horn and arm signals, as well as satellite alerting devices where available. Module 1 and module 3 cover them in detail.
No. The course introduces standard IMO phraseology and clear-language techniques step by step, with support materials and practice exercises.
No. Navalis teaches the content and procedures; official radio operator certificates are issued by the competent authority after its own examination. The course is a solid preparation for understanding those procedures.
Yes. It is designed for anyone responsible for safety or emergency response, at sea, in ports, in industry or in outdoor activities; the admission interview confirms that it suits your profile.
Through practical exercises in each module, simulated emergency scenarios with feedback and a final project consisting of an emergency signaling and communication plan.
Fully online, through a virtual campus available 24/7, with live sessions that are recorded, downloadable materials, discussion forums and tutorials with the teaching staff.
The course comprises 300 hours of study across 5 modules of about 60 hours each and ends with an applied project. You can progress at your own pace within the schedule set when you enroll.
