What are the potential hazards of chlorine?

Exposure to low levels of chlorine can result in nose, throat, and eye irritation. At higher levels, breathing chlorine gas may result in changes in breathing rate and coughing, and damage to the lungs. Additional symptoms of exposure to chlorine can be severe. Workers may be harmed from exposure to chlorine.

Is chlorine solution Dangerous?

The concentration of chlorine in public drinking water is extremely low and not harmful to human health. Mixing products that contain chlorine with other chemicals can also result in the release of dangerous chlorine gases.

Is liquid chlorine hazardous?

Blurred vision. Burning pain, redness, and blisters on the skin if exposed to gas. Skin injuries similar to frostbite can occur if it is exposed to liquid chlorine. Burning sensation in the nose, throat, and eyes.

What level of chlorine is too high?

When free chlorine is over 5.0 ppm, swimmers may experience itchy skin, irritated eyes, and/or dry hair. Pools will naturally gas-off chlorine from the surface, and very high levels can irritate airways and lungs. This is especially true for indoor pools. At chlorine levels over 10 ppm, swimsuits can begin to fade.

How do you handle chlorine safely?

Eye/Face Protection: Wear chemical safety goggles. A face shield (with safety goggles) may also be necessary. Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots. Coveralls or long sleeve shirts and pants in some operations.

Can chlorine damage your lungs?

Chlorine gas is a toxic respiratory irritant that is considered a chemical threat agent because of the potential for release in industrial accidents or terrorist attacks. Chlorine inhalation damages the respiratory tract, including the airways and distal lung, and can result in acute lung injury.

Chronic (long-term) exposure to chlorine gas in workers has resulted in respiratory effects, including eye and throat irritation and airflow obstruction.

How to increase the safety of chlorine dioxide solution?

To increase the safety of chlorine dioxide solution, eliminating or reducing the impurities and increasing the gas chlorine dioxide concentration in a solution is a reasonable approach. Herein, a clean and concentrated process for chlorine dioxide gas production was designed and implemented.
