Accidental freon release inside ISS
While doing maintenance to the air-conditioning system on the Russian portion of ISS two Russian astronauts accidently vented freon into the station’s atmosphere.
“Cosmonauts Samokutyaev and Serova performed steps to release pressure in the Russian segment’s air conditioner system by venting khladon gas (Freon 218) overboard. However, several of the quick disconnects that were actuated during the procedure exhibited leaks. As a result, the Khladon was vented into the cabin instead. The quantity released was approximately 100 g, which results in a density of 117 mg/m3 over the volume of ISS, which was below the stated ISS zero risk flight rule limit of 150 mg/m3. As part of nominal air scrubbing process, the Russian Air Purification System and the USOS Trace Contaminant Control System (TCCS) will remove residual Khladon from the atmosphere,” the NASA blog said.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

So a little under 4 ounces, I don’t know how this refrigerant reacts to atmosphere, but if its anything like common transport refrigerants, I think it’s a non issue, I imagine it would be scrubbed by the ventilation system, and made inert.
