Pool rules are important because: Prevent Accidents and Injuries: Ensuring pool safety by using Pool Rule Signs displaying information like pool depth, absence of lifeguard, diving restrictions, running or playing restriction, and other rules is important. When pool users are more aware of safety, there are fewer chances of drowning, drain entrapment, slipping, back pain, spinal and other injuries. Required By Law: Pool safety is not just important, it is also a legal requirement for public pools. Strict laws are framed by each state’s government for public pool owners and impose penalties from hundreds to thousands of dollars on those not in compliance.
