Pool safety works in layers, on the assumption any single one can fail. Most residential pools have exactly one layer, which is the barrier.
The barrier
Codes generally require a barrier of specified height with self-closing, self-latching gates opening outward, with the latch high enough to be out of a child’s reach.
Metro has specific requirements and they are worth confirming rather than assuming, particularly on an older pool installed under different rules.
Layers beyond it
Door alarms on any house door giving direct pool access. Surface or immersion alarms in the water. A safety cover that supports weight rather than a floating one.
And the layer that matters most: designated adult supervision with no other task, rather than everyone assuming someone is watching.
- Compliant barrier with self-closing, self-latching gates
- Alarms on house doors leading to the pool
- A safety cover, not a floating cover
- Designated supervision with no competing task
- Rescue equipment within reach, and CPR knowledge
The gap in most setups
Direct access from the house. Where a door opens onto the pool area inside the barrier, the barrier does nothing against a child who lets themselves out.
Door alarms and self-closing devices on those doors are what close it, and they are frequently missing.
Covers
A floating solar cover is a hazard rather than a safety device — a child on one is under it, not on top. Safety covers anchor to the deck and support weight.
The distinction matters and the two get confused because both are called covers.
