[header] How to dive into a pool [title] Find a deep diving pool. [step] Since diving means entering a pool headfirst, the water has to be deep enough so that you don't hit the bottom too quickly and risk getting a head or spine injury. 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. [substeps] If you're unsure how deep a pool is, it's best to avoid diving there.
