A Practical Guide to Calling 1669, Reporting an Emergency and Helping a Casualty Until the Ambulance Arrives
When an accident happens, knowing how to call Emergency Medical Services (EMS) can make a critical difference. Whether you witness a road traffic collision, a workplace accident, a drowning, a severe fall or a sudden medical emergency, your ability to communicate clearly with emergency dispatchers can help responders understand the situation and identify the assistance required.
In Thailand, the main emergency medical number is 1669. It connects callers with the emergency medical services system for assistance with serious injuries and medical emergencies. In Bangkok, 1646 is also listed as the number for the Erawan Emergency Medical Center.
Remember: 1669 — Emergency Medical Services in Thailand.
But knowing the number is only the first step. You must also be able to explain where the emergency is happening, what has happened, how many people are injured, what dangers remain and how responders can reach the casualty.
This guide explains how to recognise a medical emergency, make an effective emergency call in Thailand, follow the dispatcher’s instructions and provide appropriate first aid while professional help is on the way.
1. When Should You Call Emergency Medical Services?
You should contact EMS when a person has a potentially life-threatening condition, a serious injury or symptoms that require urgent medical assessment.
Do not delay calling for help because you are unsure how serious the situation is. If the person appears critically ill or injured, call 1669 and explain what you observe.
Call 1669 immediately if a person:
-
Is unconscious or unresponsive and does not respond normally to voice or touch.
-
Is not breathing normally, is gasping or has severe difficulty breathing.
-
Has severe chest pain or other symptoms that could indicate a heart attack.
-
Shows possible signs of a stroke, such as sudden facial drooping, arm weakness or speech difficulties.
-
Has severe bleeding that cannot be controlled quickly.
-
Has sustained a major injury following a road traffic collision, a fall from height or a serious workplace accident.
-
Has suffered a severe burn, major crush injury or suspected serious spinal injury.
-
Is experiencing a prolonged or repeated seizure, has difficulty breathing during a seizure, or remains unresponsive afterward.
-
Has experienced an electric shock with concerning symptoms or a serious electrical injury.
-
May have been poisoned or experienced a serious allergic reaction.
-
Has been rescued from drowning and has breathing difficulties, reduced consciousness or other concerning symptoms.
These examples are not exhaustive. If you suspect a life-threatening emergency, call for professional assistance rather than waiting for symptoms to worsen.
What if the person says they are fine?
A person involved in an accident may initially feel relatively well despite having a serious injury. Shock, adrenaline and the circumstances of the incident can make it difficult to assess the severity of an injury.
Be particularly cautious after a high-impact collision, a fall from height, a head injury or an incident involving crushing forces.
Do not rely solely on whether the casualty says they feel fine. If there are concerning signs or a potentially serious mechanism of injury, seek appropriate medical assistance.
2. Who Should Make the Emergency Call?
The emergency call should be made as soon as possible when urgent medical assistance is required. The person who calls does not necessarily have to be the person providing first aid.
If several people are present, assign specific tasks rather than asking everyone to help at once.
For example:
-
Person 1: Calls 1669 and communicates with the dispatcher.
-
Person 2: Assesses the casualty and provides first aid within their training.
-
Person 3: Retrieves the first aid kit and AED, if available.
-
Person 4: Meets the ambulance and guides responders to the casualty, if it is safe to do so.
In a workplace, a designated first aider or safety officer may coordinate the response. At a road traffic collision, bystanders can help by calling emergency services, warning approaching traffic from a safe position and identifying the exact location.
What if you are alone?
If you are alone with a casualty, use your mobile phone to call 1669 and activate the speakerphone function when possible. This allows you to communicate with the dispatcher while keeping your hands available for first aid.
Follow the dispatcher’s instructions. If the casualty is unresponsive and not breathing normally, immediate CPR and early AED use are critical.
Do not delay calling simply because you are not a medical professional. Your role is to report what you observe and follow the instructions provided.
3. How to Call 1669 in Thailand: Step by Step
Step 1 — Call 1669
Dial 1669 from your phone as soon as you recognise a serious medical emergency.
Tell the operator that you need emergency medical assistance. Explain whether the incident involves an accident, an illness, an unconscious person, a breathing problem or another urgent condition.
Stay calm and speak as clearly as possible.
Step 2 — Give the exact location
Your location is one of the most important pieces of information. Emergency responders cannot reach a casualty if they cannot identify where the incident occurred.
Provide as much useful information as possible:
-
Province, district and street or road name.
-
Building name, hotel, office, factory or construction project.
-
House number, building entrance, floor or room number.
-
Nearby landmarks, junctions or recognisable signs.
-
Highway number, kilometre marker, direction of travel or nearest exit.
-
GPS coordinates or a map location, if available and useful.
If you are inside a large building, give the entrance and floor where the casualty is located. At a construction site, identify the correct gate and explain whether responders need to reach a particular building, floor or work area.
Never assume the dispatcher automatically knows your location. State it clearly.
Step 3 — Explain what happened
Give a short, factual description of the incident.
Examples:
-
“A motorcycle has collided with a car. One person is unconscious.”
-
“A worker has fallen from scaffolding and is not responding.”
-
“An adult has collapsed and is not breathing normally.”
-
“A person has severe bleeding following an industrial accident.”
-
“A swimmer has been pulled from the water and is not breathing normally.”
Avoid guessing at a diagnosis. Report what you saw and what the casualty is doing now.
Step 4 — Report the casualty’s condition
Tell the dispatcher whether the person is conscious, breathing normally and bleeding heavily. Mention any other serious signs you can observe.
If there are multiple casualties, state the approximate number and identify whether anyone appears to be in immediate danger.
Do not delay the call to perform a detailed examination. Report what you know, then answer the dispatcher’s questions.
Step 5 — Identify hazards and access problems
Inform the dispatcher about hazards that could endanger the casualty, bystanders or rescuers.
These may include:
-
Fire, smoke or an explosion risk.
-
Fuel spills or hazardous chemicals.
-
Electrical cables or exposed live equipment.
-
Unstable structures or falling debris.
-
Heavy traffic or dangerous road conditions.
-
Floodwater, strong currents or difficult terrain.
-
Locked gates, security barriers or restricted site access.
Explain the safest available route to the casualty and any special access requirements.
Step 6 — Follow the dispatcher’s instructions
The dispatcher may ask additional questions or provide instructions for immediate care, including CPR.
Listen carefully, follow the instructions and do not hang up until the dispatcher tells you to do so, unless the connection is lost or another urgent circumstance prevents it.
If you do not understand an instruction, ask the dispatcher to repeat or clarify it.
4. The E.T.H.A.N.E. Method: A Simple Way to Report an Emergency
When people are frightened or under pressure, it is easy to forget important details. A structured reporting method can help organise information.
One method used in incident reporting is E.T.H.A.N.E. It can help remind trained responders and communicators of key information, although it is not a substitute for answering the emergency dispatcher’s questions.
E — Exact location
Where is the casualty?
Give the address, building, floor, road, landmark or GPS coordinates. Include the best entrance and any access restrictions.
T — Type of incident
What happened?
For example, a road traffic collision, fall from height, drowning, electrical injury, fire or sudden medical emergency.
H — Hazards
Are there any immediate or potential dangers?
Report fire, smoke, electricity, unstable structures, chemicals, traffic or other hazards. Do not enter an unsafe area to obtain more information.
A — Access
How can responders reach the casualty?
Explain the safest route, the correct entrance and whether someone can guide the ambulance to the scene.
N — Number of casualties
How many people need help?
Give your best estimate. If the number is uncertain, say so. Report anyone who appears to have a life-threatening condition.
E — Equipment and resources
What assistance may be required or is already available?
For example, there may be several casualties, difficult access, a suspected cardiac arrest or a need for specialised rescue. Report relevant facts and follow the dispatcher’s questions rather than trying to decide independently what resources should be sent.
The most important rule is to communicate clearly and honestly. You do not need to memorise a special reporting system to call 1669 effectively.
5. What Should You Say When Calling 1669?
Here is a practical example of an emergency call.
Illustrative scenario — not a recorded real emergency call
Scenario: A construction worker falls from a ladder at a commercial building in Bangkok. The worker is conscious but confused and complains of severe pain. A colleague calls 1669 for an ambulance.
CALLER:
“Hello, my name is "Your name", I need an ambulance. A male worker has fallen from a ladder at a commercial building in Bangkok.”
EMS DISPATCHER:
“Where exactly did the accident happen?”
CALLER:
“The address is [full address], near [recognisable landmark]. We are at the [specific entrance]. I can send someone to guide the ambulance to the injured worker.”
EMS DISPATCHER:
“How many people are injured? Is the worker conscious and breathing normally?”
CALLER:
“One person is injured. He is conscious and appears to be breathing, but he is confused and has severe pain after the fall.”
EMS DISPATCHER:
“Is the area safe? Are there any electrical hazards, falling objects or other dangers?”
CALLER:
“The immediate area appears safe. We are keeping people away from the ladder and will follow your instructions.”
EMS DISPATCHER:
“Tell the patient stop moving. Stay on the line and follow my instructions. Tell me immediately if the worker’s condition changes.”
The caller continues answering the dispatcher’s questions and follows the instructions provided until emergency responders arrive.
This is an illustrative conversation for educational purposes, not a recording or transcript of an actual emergency call. Real dispatcher questions may vary.
What makes this call effective?
The caller provides the location, type of incident, number of casualties, current condition and access information. The caller also avoids making a definitive diagnosis and does not move the casualty unnecessarily.
In a real emergency, the exact questions and sequence will depend on the dispatcher and circumstances.
6. What Should You Do While Waiting for the Ambulance?
Calling EMS is only the beginning. While waiting for responders, take appropriate action without putting yourself or others in danger.
Make the scene safe
Check for traffic, electricity, fire, unstable structures, chemicals or other hazards.
At a road traffic collision, remain alert to approaching vehicles. At a workplace accident, stop nearby machinery or isolate hazards only if this can be done safely and within your authority.
Never become a second casualty by entering an unsafe scene.
Check responsiveness and breathing
If it is safe to approach, check whether the person responds to voice or gentle stimulation.
If the person is unresponsive, assess whether they are breathing normally. Gasping or occasional irregular breaths are not normal breathing.
If the person is unresponsive and not breathing normally, call 1669, begin CPR and use an AED as soon as available. Follow dispatcher instructions and the AED’s prompts.
If someone else is present, ask them to bring the AED and first aid kit while you provide care.
Control severe bleeding
For life-threatening external bleeding, apply firm, direct pressure to the wound with an appropriate dressing or clean material.
If bleeding is severe and a tourniquet or haemostatic dressing is indicated, use it if you are trained and the equipment is available. Follow the dispatcher’s instructions.
Do not repeatedly lift the dressing to check the wound, as this may disrupt clot formation.
Avoid unnecessary movement
After a fall, collision or other major trauma, suspect possible head, neck or spinal injuries.
Encourage the casualty to remain still and avoid unnecessary movement. Do not move them unless an immediate danger requires it or movement is necessary to provide essential lifesaving care.
Protect the casualty and monitor their condition
Reassure the person, protect them from excessive heat or cold when appropriate, and monitor their responsiveness and breathing.
If their condition changes, inform the dispatcher. Do not give food, drink or medication unless directed by an appropriate medical professional or dispatcher.
Prepare for the ambulance’s arrival
If safe, send someone to the entrance or roadside to guide the ambulance. Clear access routes and ask bystanders to make space.
Gather relevant information about the incident, known medical conditions or medications if readily available, without delaying essential care.
When the emergency team arrives, explain what happened, what you observed and what first aid was provided.
7. Common Mistakes to Avoid When Calling EMS
Even well-intentioned people can make mistakes when they are stressed. The following actions can make an emergency response more difficult.
Mistake 1: Giving an unclear location.
Saying “near the shopping centre” or “somewhere on the main road” may not be enough. Give the exact address, entrance, floor or a recognisable landmark.
Mistake 2: Describing a suspected diagnosis instead of the signs.
Rather than saying “he has a stroke” when you are unsure, describe the observed symptoms: sudden weakness, facial drooping or difficulty speaking.
Mistake 3: Hanging up too early.
The dispatcher may need additional information or may guide you through lifesaving actions. Stay on the line and follow instructions until told otherwise.
Mistake 4: Moving an injured person unnecessarily.
Moving a casualty after a fall or collision may worsen certain injuries. Avoid unnecessary movement unless an immediate danger or lifesaving intervention makes it necessary.
Mistake 5: Waiting for symptoms to become severe.
Unconsciousness, abnormal breathing, severe bleeding and other major warning signs require urgent attention. Do not wait to see whether the person improves.
Mistake 6: Assuming another person has called.
In a crowded scene, everyone may assume somebody else has contacted emergency services. Assign one person clearly to make the call and confirm that it has been done.
Mistake 7: Forgetting to guide the ambulance.
Large buildings, factories, hotels and construction sites can be difficult to navigate. If safe, arrange for someone to meet the ambulance and lead responders to the casualty.
Mistake 8: Putting yourself in danger.
Do not enter burning buildings, approach live electrical equipment or walk into moving traffic to reach a casualty. Tell the dispatcher about the hazard and wait for appropriate assistance.
8. What If You Do Not Speak Thai?
Thailand receives international visitors and has workplaces with employees from many countries. A medical emergency may involve someone who does not speak Thai confidently.
If you need to call 1669 and are not fluent in Thai:
-
Start by stating that you need an ambulance and identify your location as clearly as possible.
-
Provide the street, building and nearby landmark names slowly.
-
Use a map pin or GPS coordinates if available and useful.
-
Ask a Thai-speaking colleague, security officer or bystander to assist with communication if they are immediately available.
-
Give short, factual descriptions of the casualty’s condition.
-
Keep the phone available for questions and instructions.
Do not delay an emergency call while searching for a translator. Call first, communicate the essential information and seek language assistance as soon as possible.
For workplaces, hotels, schools and construction sites, it is helpful to prepare an emergency location card with the address in Thai and English, GPS coordinates, access instructions and the relevant contact numbers.
9. How Businesses and Workplaces Can Prepare for an EMS Call
Organisations should not wait for an accident before deciding how to contact emergency services.
A workplace emergency plan should identify who calls 1669, who provides first aid, who retrieves emergency equipment and who guides responders to the casualty.
The plan should be adapted to the workplace. A hotel may need to identify the correct guest-room floor and service entrance. A school may need to specify the building and gate. A factory may need to explain access restrictions and chemical hazards. A construction site may need to identify the project entrance, work area and safest route to the injured worker.
Recommended workplace preparations
-
Display 1669 prominently in relevant emergency information.
-
Train employees to recognise serious medical emergencies.
-
Identify designated first aiders and clarify their roles.
-
Make first aid kits and AEDs accessible, where provided.
-
Keep the exact workplace address and GPS coordinates available.
-
Prepare clear directions for emergency vehicle access.
-
Establish procedures for calling, guiding and briefing responders.
-
Practise realistic emergency scenarios and review performance.
-
Ensure multilingual staff can communicate essential location and incident details when necessary.
Emergency planning should be tested in practice, not just documented on paper.
10. Why First Aid, CPR and AED Training Matters
Calling an ambulance is essential, but professional responders may need time to reach the casualty. Appropriate care during this interval can be critical.
First Aid CPR AED training teaches participants to recognise emergencies, activate emergency medical services, perform CPR, use an AED and provide appropriate immediate care within their training.
For businesses and organisations, practical training can also improve communication, teamwork and confidence during an emergency.
Bangkok First Aid provides First Aid CPR AED training for individuals and organisations in Bangkok and throughout Thailand. Training can help employees prepare for medical emergencies at work, at school and in other environments.
Training should be selected according to the organisation’s risk assessment, workforce needs and applicable requirements. It does not replace emergency medical services, but it can help people respond more effectively while professional help is on the way.
Conclusion: Know the Number, Give Clear Information and Act Safely
When a serious accident or medical emergency happens, a clear emergency call can help connect the casualty with the assistance they need.
Remember the essentials:
-
Call 1669 for emergency medical assistance in Thailand.
-
Give the exact location and explain how responders can reach the casualty.
-
Describe what happened, the number of casualties and their current condition.
-
