And you call the 999 service in M'sia, what is the 1st thing you gonna say? What happen? How many people involved? Dr. Chew has posted a useful mnemonics in his blog. When you call next time, just remember use the mnemonic ETHANE.
What' does ETHANE stand for?

T = Type - The nature of the incident (trauma, non-trauma, heart atack, motor-vehicle accident), including how many vehicles, buildings etc. are involved

H = Hazards - Both present and potential (e.g., explosion, spillage of combustible materials, highly volatile hydrocarbons, chemicals, etc)

A = Access - Best route for emergency services to access the site, or obstructions and bottlenecks to avoid

N = Numbers - Numbers of Casualties, Dead and Uninjured on scene

E = Existing Emergency Services - Which services are already on scene, and which others are required - s0 as not to duplicate services, and for better utilization of services in other concurrently emergency happenings.
