I have written many articles on “scrubbing NH3” in preparation for line breaks/equipment openings or emergency removal from a compromised container and with NH3 the scrubbing media is simply water (H2O). I learned these “scrubbing” methods while working one summer in an internship and the safety pro who hired me was also an MSU graduate and he called these simple, yet highly effective, set-ups a “KY Scrubber”. With chlorine, we can have some simple set-ups, but our scrubbing media is a bit more tricky – but still fairly simple. Chlorine is readily absorbed in and reacted with an alkaline solution, but know this… When absorbing chlorine in alkaline solutions, the heat of the reaction is substantial, so be SURE your KY Scrubber is not made with a “redneck bucket”!
