Having watched the video in the link there is actually not a lot wrong with it. The guy states you should dial “112” on your mobile as this will work anywhere in the world (it’s part of the GSM standard, as well as a European directive). Good advice.
He then mentions he’s in the UK and gives some examples of dialling “112” in the UK. What he doesn’t say is if you are in the UK, you can also dial “999” and this works in EXACTLY the same way.
I assume this is because the message “dial 112” is a lot more succinct than “dial 112, or if you’d prefer dial an alternative local number if you know it, such as 999 in the UK, although that won’t work on a locked non-UK phone, so in that case you may still have to use 112”
The EU also provides plenty of information about “112”, including things like geolocation of mobile handsets etc. But again the EU does not publicise the option of “999” in the UK.
So the assumption people (incorrectly) jump to when they hear about “112” without any mention of “999” is that it must be something new and/or different to “999”. It’s not – in the UK it is exactly the same. And has been for almost 20 years.
http://en.wikipedia.org/wiki/999_(emergency_telephone_number) is a pretty good summary of the situation. While Wikipedia has it’s faults, it’s usually a better source than a Facebook status that ends with the phrase “make sure you pass this info on to everybody you know!”
“999” remains the official emergency number because it is known by just about everybody (compared to 13% who are aware of “112”) and changing it would introduce confusion. However, I know some fire engines (for example) have both numbers shown on the side, where previously they only showed “999”.
