Pit hound perhaps you are unaware that Ammonium Fluoride is Hydrofluoric Acid buffered with Ammonia.
So yes - ZEN is using Hydrofluoric Acid. They have just buffered it with another dangerous chemical
HF (Hydrofluoric Acid) + NH3 (Ammonia) = NH4F (Ammonium Fluoride)
Let's see if ZEN can convince the CLFN that Ammonium Fluoride is GREEN or BENIGN or qualifies for the CleanTech Sector.
Lets see if the CLFN believes that ZEN can GUARANTEE safe transport, storage, processing and disposal of the Ammonium Fluoride.
AMMONIUM FLUORIDE solvay.us
Ammonium fluoride is a corrosive chemical and contact can severely irritate and burn the skin and eyes causing possible permanent eye damage. Breathing ammonium fluoride can severely irritate and burn the nose, throat, and lungs, causing nosebleeds, cough, wheezing and shortness of breath. Contact of ammonium fluoride with water or moist skin can release hydrofluoric acid, a very dangerous acid. (that would include the ground water on the CLFN lands). Ammonium fluoride crystals are hydroscopic (absorb moisture from the air). They also sublime (vaporize without going into a liquid state).
Inhalation or ingestion of large amounts of ammonium fluoride can cause nausea, vomiting and loss of appetite. Exposure to high concentrations or long term exposure to lower concentrations can cause fluoride poisoning with stomach pain, weakness, convulsions, collapse and death. It can also cause deposits of fluorides in bones and teeth, a condition called fluorosis. Symptoms of fluorosis may include pain, disability and discoloration of teeth.
Following good industrial hygiene practices will minimize the likelihood of exposure; however, persons involved in higher risk activities should always wear proper personal protective equipment such as rubber gloves and boots, an acid or slicker suit, respiratory protection, goggles and a hard hat. In instances where the potential for splashes is high, a face shield should also be worn. |
