1 Prohibits head first diving in water depths less than 8 feet. 2  Restricts use of starting blocks to competitive swimmers or swimmer training activities.  Requires new installation (effective October 7, 1992) of starting blocks to be in the deep end in at least 6 feet of water.
The Red Cross considers nine feet to be a good depth for diving if you want to be especially cautious, but the diving area in many pools is eight feet deep. Never dive into a pool that's less than eight feet deep. If you're unsure how deep a pool is, it's best to avoid diving there. It can be hard to gauge a pool's depth just by looking. Find a pool where the depth of the water is clearly marked. In many cases there will also be a sign posted that specifies diving is permitted there.
