This webinar is on the application of HF acid in the oil & gas industry in order to recognize its commercial importance as well as its less known toxic effects on the worker’s health upon its exposure. I will also present regarding how long this toxic material has been in use in the oil & gas industry globally & and ask: is there any alternative to HF acid? If there is, then why is HF acid still preferred even today? I will also share a real HFacid exposed scenario with the audience to examine how HF acid exposure is lethal & even fatal, while medics are not well trained, specifically, to treat HFacid burns & injuries.
