There are three main types of water safety signs you will find when you are around water. Each one has its own meaning, but all of them work to the same system. If you go to the seaside, then there are sometimes special flags to also look out for.
Signs that warn you of danger, are always:
1. Triangle shaped
2. Yellow background,
3. With black symbols
They are placed to help you spot a hazard that is not always obvious
