Here is some information you might want to know about.
It is evident that many people are not aware of the risks that exist with the use of Hydrofluoric Acid and Ammonium Biflouride. This information will help you understand why the risk is real and should not be ignored.
You should be aware of the following facts relative to HF or ABF:
1. HF is one of the strongest inorganic acids available, used primarily for industrial purposes (i.e., etching glass, petroleum refining, and electronics manufacturing under a highly controlled environment)
2. When using HF at any known concentration that will clean, it will corrode most metals including stainless steel, attack concrete, pit glass, and negatively effect most painted surfaces.
3. HF is considered Toxic and therefore a known poison when absorbed through the skin, ingested or inhaled. The effects of the exposure may vary based on exposure time, concentration, surface coverage and the size of the person.
4. HF in a concentration above 0.5% may result in severe ocular damage to the eye. Fume exposure commonly causes eye irritation and can also cause ocular injury. Signs and symptoms may be delayed.
5. OSHA?s maximum permissible respiratory exposure limit is 3 parts per million average exposure in an 8-hour period.
6. Many insurers will not issue policies or increase rates if they are aware that these products are being used, so be sure to check with your carrier for coverage if you are planning to use HF or ABF.
There have been several articles in PCD highlighting industry issues regarding HF. You should be able to find them in their archives. If not, e-mail me and I can send you a few.
