Questions
What is the difference between Deep water and Danger deep water?
Both warn about deep water. 'Deep water' uses the yellow warning triangle; 'Danger deep water' is a text sign in white on red for places where the risk is higher.
Does a sign make a pond safe?
No. A sign warns people; it does not remove the risk. Landowners and venues have wider duties.
Is the No swimming sign suitable for open water?
Yes as a notice.
Can I use Deep end and Shallow end signs without a pool?
They are written for pool depth markers. For open water use the Deep water signs.
