The National Poisons Information Service (NPIS) advise that for responsive patients, immediate decontamination is the priority for individuals exposed to hydrofluoric acid.Even relatively low strength hydrofluoric acid is toxic and has the potential to cause serious tissue damage and death when contaminated individuals are not treated swiftly. C-Gel is a high performance calcium gluconate gel. C-Gel combines with and neutralises the fluoride ion present in HF acid. This helps to prevent pain and tissue damage caused by HF acid whilst a patient is in transit to hospital.C-Gel is an easy to use cream, which can be self-administered or applied by a suitable first aider, available as a 40g tubeSome examples where Hydrofluoric acids may be encountered are industrial chemistry, mining, refining, glass finishing, silicon chip manufacturing, and sanitation.
