The third option is a pool fence. Pool fencing is traditionally made using galvanised steel, with alternatives now made from fabric, wood, plastic and glass – all of which need be erected to a minimum height of 1.2 m, with no means for a child to climb over or under the fence. It should be a smooth vertical surface, secured into the ground, and the gate must be lockable and self-closing. Pool fencing provides a means to secure the area that a pool is in rather than the pool itself. Many people feel that a fence provides a higher degree of safety than a net, but many drownings still happen in pools that are fenced. The main benefit of a pool fence is that there is no fitting or removal required to access the pool.
