Pool chemicals that lack attention and care can be hazardous to swimmers and those who are nearby. Over 4,800 people had to visit the emergency department for chemical related injuries in 2012 alone, according to the U.S. Centers for Disease Control and Prevention. Nearly half of those patients were under the age of 18. These accidents can manifest a number of ways. Here's how you can avoid chemical injuries.

Examine the water
For starters, be vigilant of the color of your swimming pool. If it's murky, green or just seems off in any other way – don't get in. It could be a sign that your chemicals aren't properly balanced and it might be dangerous to take a swim. 

Regular maintenance is key
Enlist the services of a reputable company. San Diego pool service professionals can balance the chemicals in your swimming pool on a regular schedule so you won't have to think twice about it. A primary cause of injury and recreational waterborne illness is swimming in water that isn't properly balanced.

The chlorine level should stay between 1.0 and 3.0 parts per million. It needs to be adjusted because the human body alters this level, as does a number of outside sources, like objects that fall into the water. On the flip side, too much chlorine is also bad because it can burn your skin. Don't add it in yourself because this could happen to you.

Less chlorine 
Finally, if you're looking into upgrades, consider doing away with your chlorine generator altogether. A salt system produces a significantly less amount of the chemical and can be good for your skin and hair. Say goodbye to itchy eyes and let San Diego pool service professional install a salt system in your pool. Regular clients are eligible to receive one for free.

In general, it's better to be safe than sorry. Whenever you're on the fence about your pool's chemicals – call a professional. It can save you from an injury.
