If you have a pool or spa, you must have a CPR (cardiopulmonary resuscitation) sign prominently displayed, ideally in eye-sight of the step area, as this is the most obvious place assistance would take place.
Pool & Spa Fences & Gates
Pool and spa fences and barriers are required by legislation for any swimming pool or spa in excess of 300mm (30cm) in depth and must be maintained for the life of the pool or spa, this includes keeping the area around the safety barrier free from climbable objects or plants that can be used to gain access to the pool area.
