Health experts warn of the dangers of excessive exposure to chlorine, which can cause sickness and injuries. Instructions for safely chlorinating a pool usually call for a maximum of four parts per million of chlorine in the water.
“Chlorine is the most common disinfectant used in swimming pools, but it’s not the only one,” said Dr. William Schaffner, director of the Center for Environmental Health at the University of California, San Francisco.

What chlorine level is safe to swim in?
Most germs can be killed in a few minutes with the proper use of free chlorine. The CDC recommends a free chlorine concentration of at least 1 ppm in pools, spas, and hot tub. *Free chlorine is a byproduct of chlorine disinfection. It is not a disinfectant.
Is it safe to swim in pool with chlorine?
It is recommended to wait at least 4 hours before swimming after adding chlorine to a pool. The best way to tell if a pool is ready to swim in is to test the chlorine level. It’s a good idea to go swimming in the pool once the chlorine level drops to less than 50 parts per million.
Chlorine levels can also be tested by using a water test kit. These kits can be purchased from your local hardware store or online. The kits are designed to measure the amount of chlorine in a sample of water. If the level is above 5 ppm, then the sample is contaminated with chlorine and should not be used for swimming purposes.
Can high chlorine hurt you?
Too much chlorine in the pool water can be dangerous. Asthma, lung irritation, and potentially skin and eye irritation can be caused by exposure to over-chlorination. Excess chlorine can be toxic to fish and other aquatic life, as well as being potentially bad for you.
Well, there are a number of things you can do to reduce the amount of chlorine you’re exposed to in your pool.
Should I shock pool if chlorine is high?
If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. To hit what is known as the break point, you will need to raise free chlorine to 10 times your combined chlorine. It’s a good idea to deal with combined chlorine levels as high as you can.
“Break point is the point at which the chlorine in the water will begin to break down and release chlorine gas into the air. It is important to know that the break point of chlorine is not the same as the level of chloramine in your water. Chlorine breaks down in water at a rate of about 0.1 mg/L per hour, while chloramines are broken down at about 1.5 mg per L per day.
This means that if you have a water system that has a chlorine break of 10 mg, and you add 1,000 L of water to the system, your chlorine breakdown rate will be about 2,500 mg / hour. However, if your system does not have enough chlorine, then you may have to add more chlorine.
Can you swim with chlorine at 10 ppm?
It depends on who you ask, but the range is between 1 to 5 parts per million. 10 parts per million chlorine is not safe for swimming.
If you’re swimming in a pool that has been treated with chlorine, you should not be swimming more than 1.5 to 2.0 ppm of chlorine in your pool water.
If the chlorine levels in the water are higher than this level, it’s time to call your local water treatment plant to see if you need to change your water source.
How long does it take for chlorine to evaporate from a pool?
The chlorine will evaporate more quickly because of the warmer air. If you put the water in a jug that’s left open in the refrigerator, the chlorine should evaporate in 24 hours. Before you use the water, leave it at room temperature for a day or two. Chlorine is a colorless, tasteless, and odorless gas.
It is soluble in water, but not in organic solvents such as alcohol, ether, or methanol. In the presence of oxygen, chlorine reacts with water to form hydrochloric acid, which dissolves organic matter. The acidity of the solution is proportional to the amount of chlorine in it, so the more chlorine you have in your solution the less acidic it will be.
When the pH of a solution drops below 7.0, it is said to be neutralized. Neutralization is the process of removing chlorine from an acidic solution by the addition of an alkali. This is done by adding sodium hydroxide or sodium bicarbonate, both of which are available at most hardware stores.
How long should you wait to swim after shocking pool?
After shocking your pool, it is safe to swim once your chlorine levels are under 5 parts per million. It’s a good idea to check your pool daily to make sure the chlorine level isn’t too high or too low.
