How to make an emergency call

[Lukey-Loki]

True. Emergency services get an approximate location of a cellphone by signal strength triangulation from the nearby transmission masts. In rural areas where only one mast has contact, this triangulation doesn't work (obviously) and location can only be determined to within a few miles from the mast serving the call.

 

I see.

999 goes back to the days of analouge phone exchanges, gave the breakers in the exchanges time to lock in and less chance of a missdialed no. It doesnt matter which no. you use, as a chainsaw operator you should have a note of your exact location on your risk assesment that you "did" for the job, and if your in a remote locatiob, you should have the map ref for your helivac,just in case, just remember minutes matter with a major incident
