Knowing the correct way to report an emergency can help the authorities save time and lives.
Most importantly, the person reporting the incident must decide which service is required.
If firefighters are needed, call 997. If you require medical help, call 998, while if it is a matter for the police, call 999.
Capt Saeed Al Nadhani, from Ajman's operations room, said choosing the correct number could be the difference between life and death.
"Calling police instead of civil defence wastes at least two minutes, which are of much value when lives are at stake," he said.
He cited the example of someone reporting a road accident who failed to mention someone was injured. By the time the police patrol arrived, precious time would be wasted while an additional call was made to the ambulance service.
When calling the emergency services, remain calm and confident to give the most accurate account of the situation.
State your full name and phone number, then detail the nature of the accident and give an accurate account of your location.
Tell the emergency services the number of casualties and describe the type and extent of any injuries.
If you know of any hazards that rescuers might encounter on their way, ensure they are aware of them.
If time allows, try to repeat all the information.
