My health collapsed eight years ago. Coating sprays at work, the kind which are used on the outside of glass bottles to prevent scratching when they rub against each other, had been burning my airways and throat whenever I adjusted them. For a long time the only significant effect of this which I noticed was that it became impossible to breathe when there was any pressure on my chest, such as when in water. Management refused me PPE and the union complained that there was nothing they could do. When my health finally gave out it was sudden. A period of panic attacks and confusion, as I am now aware because of hypoxemia, before I experienced heat stroke. It took me years to learn that the polyethylene which the sprays were supposed to be were actually a manufactured mixture of nano-silica particles called silanols. These are the same particles which cause silicosis when people are exposed to silica dust. These silanols are sprayed on a wide range of things now; clothing, glass, plastics. Pretty much anything which they consider worth the effort. They are used as preservatives in food and as the coatings on medications. They are used as dental fillings. They are looking for further commercial uses all of the time. One of these silanols burned holes in my gastrointestinal tract. They induced the respiratory issues. I have read about people drinking alcohol and having the alcohol blamed for the damage, by physicians, when it was probably caused by the coating spray which had been returned to a liquid state. I keep reading and hearing experts claiming that these nano-silica particles will be the next huge toxic scandal which comes to light so there have to be others who have experienced similar stories to my own. I have read an Australian government report explaining that contents of sprays like these join with environmental dust around the workplace; inhaled throughout the day. Far too often I have heard people complaining that they have no idea why their health has collapsed so if you just have a similar story I would like to hear it because I may have answers which you have been looking for.
