And, naturally, salt is the solution to injuries at public and home pools.

The Centers for Disease Control and Prevention (CDC) estimates that up to 100 people every week are treated in U.S. emergency rooms for injuries related to pool chemicals. Half are associated with home pools.

CDC warns against mixing chlorine with other substances and notes that most injuries occur when individuals inhale, attempt to pre-dissolve or improperly handle pool chemicals. CDC suggests operators keep pool chemicals secure, read manufacturers' instructions on using the products and use proper personal protective equipment when working with chemicals.

What CDC could/should have added is that pool operators should eliminate most of the potential problems by switching to saltwater pools.
