What happens when sodium hydrochlorite and sulfuric acid mix?
Sodium hydrochlorite is a stabilized form of chlorine. For example, the chlorine bleach you use in your home is only about 3 percent to 6 percent sodium hydrochlorite and is mixed with water.
Sulfuric acid is an extremely corrosive oxidizer. Almost every industry uses sulfuric acid to make hundreds of different chemical mixtures. It’s commonly used in metal processing and in cleaning the surface of steel sheet.
When mixed together, the two chemicals create a very toxic chlorine gas.
According to the CDC, it is very unstable and can react with a variety of different chemicals and water when released into the environment.
Chlorine is also broken down by sunlight, which could explain why the gas reportedly dispersed later in the day.
Exposure to the gas could result in nose, throat, and eye irritation. At high levels, it could change your breathing rate, induce coughing, and potentially damage lungs.
AtchisonCounty officials closed and evacuated the county courthouse. Classes at Benedictine College were canceledfor the day.
Massive clouds of gas appeared throughout the city for nearly 90 minutes.
Facebook issued a safety check for those affected by the chemical plume.
Some roads were closed for almost an hour, but traffic has reopened.
Mosaic Life Care in St. Joseph, Missouri and other area hospitals will be on standby if additional medical help is needed.
