While tasteless and odorless, Freon does make a large impact on your air and health. Refrigerant poisoning is a serious condition that can lead to difficulty breathing, headaches, nausea and vomiting, skin and eye irritation, and coughing
If you inhale or ingest refrigerant of any kind, seek immediate emergency medical assistance. The dangers of refrigerant poisoning are serious. Freon, which is often used in refrigerants and coolants, is colorless and smells like freshly cut grass.
i live quite close to the path of the new river, which is a canal that runs from hertfordshire to islington, built in the time of elizabeth (the first) I think. a goldsmith called hugh myddelton gets all the credit, statues of him in islington and holborn viaduct, etc but the original idea was had by a bloke called edmund something or other, edmund is also my first name. the new river fills stoke newington reservoirs and the filtering station is a local landmark.
