Safety signs are a part of life. Wherever you go you will encounter at least one. The other day at the dentist I looked up and a sign informed me to switch off my mobile phone. Next to it was a sign saying no smoking! When paying a vist to the toilet I was reminded to 'Please wash your hands'. On leaving the practise it advised me to 'mind the step'.
Watching the news on TV and the reporter was standing in front of a back door with the fire door signs on it.
Pass a constructions site and you will be swamped with signs whether it is directing you somewhere or safeguarding us. Signs are our silent beacons.
Next time you are out and about see how many safety signs you can see - you will be amazed!
