The permissible exposure limit of OSHA is 1 ppm.
Chlorine levels above 4 parts per million (ppm) can be dangerous for a pool as it can cause skin and eye irritation. Additionally, high levels of chlorine can be harmful if ingested or inhaled. It is important to regularly test and balance the chlorine levels in a pool to maintain a safe and healthy swimming environment.
Chlorine can become dangerous at levels above the recommended limit of 1.0-3.0 parts per million (ppm) in drinking water. Higher concentrations of chlorine can lead to skin and eye irritation, respiratory problems, and other health risks. It's important to monitor chlorine levels carefully to ensure they remain within safe limits.
To calculate 250 ppm (parts per million) chlorine solution in water, you would need 250 parts of chlorine for every 1 million parts of water. This can be simplified to 1 part of chlorine for every 4000 parts of water (since 1 million divided by 250 is 4000). Therefore, you would mix 1 unit of chlorine with 4000 units of water to achieve a 250 ppm chlorine solution.
You can decrease the chlorine ppm in your pool by adding a chlorine neutralizer or shock treatment to reduce the chlorine levels. Another method is to dilute the pool water by adding fresh water to lower the concentration of chlorine. Regular testing and monitoring of chlorine levels will help you adjust the levels accordingly.
If free chlorine levels are at 9 ppm, it indicates a high chlorine concentration in the water, exceeding the recommended level for safe swimming. You should avoid entering the water and wait for the chlorine levels to naturally decrease with time or consider diluting the pool water with fresh water to lower the chlorine concentration. It's important to regularly test the water and ensure the chlorine levels are within the recommended range of 1-3 ppm for safe swimming.

Chlorine concentration at 500 ppm hazards to health to wash dishes in
The recommended chlorine level for disinfecting private pools can be as high as 2.0 PPM. 2 ppm is now the minimum. Recommended levels are now 1.5 ppm to 5.0 ppm.

It depends on your 'danger' level. Any amount of chlorine can be dangerous. It only takes a few drops in a gallon of water to disinfect it (kill every living thing in there) after only a few minutes. Chlorine is classified as a toxin, yet it is put in our drinking water and in pools and used in spas. For a normal sized spa, I would never pour more than a cup of chlorine into the spa. 10 ppm is considered the max. If your spa is green and you are not going to use it then feel free to pour 2 or more cups in it. You're better off draining it at this point. To prevent chlorine breakdown, it is recommended that you add stabilizer and its level will depend on how big your spa is. Chlorine is dangerous because it can damage liners and upset water balance. I suggest that you use 2 ppm of chlorine or more then shock your water for it will prevent the bad odor.
Chlorine is typically measured in parts per million (ppm) when analyzing its concentration in water or other solutions.
You only need to shock the pool if there is visible algae, or if the ppm of total chlorine is higher than the ppm of free chlorine. Generally, a level of 2-4 ppm chlorine is all you need to keep your pool sanitary. Let the level drop to that on its own, or use sodium thiosulfate to drop it quickly if you notice itchy skin from excessive chlorine.
One Tablespoon of chlorine bleach per gallon of water will give you 200 parts per million PPM. Health Department requires 50 PPM.
The ideal chlorine level in a pool should be between 1-3 parts per million (ppm) to effectively sanitize the water and prevent the growth of bacteria and algae. Testing the chlorine levels regularly and adjusting as needed will help maintain a clean and safe swimming environment.
It is impossible to tell you whether 36 ppm is dangerous if you do not tell us what substance it is you're concerned about.
A few days. You will probably be able to use the pool when the level gets to about 5.0 ppm 1) you should know the difference between residual chlorine and Free chlorine 2) Chlorine lost depend on size of you pool and temperature 3) circulation of water , temperature & size of pool will increase chlorine lost
