Looking for some advice on Hf and first aid measures. We have an area using small amounts of Hf and keep gel in the areas in the event of contamination. Additionally we issue employees with gel to keep at home in the event that contact becomes evident once out of the work environment in additon to being instructed to go to the nearest emergency department. it's the first time I've come across gel being issued for operators to take home and would appreciate some information on how you approach this. Thanks

HF would be hydroflouric acid which reacts differently to the more common hydrochloric acid; it tends to self generate and keep munching through flesh. First Aid treatment would be a good flush with water then apply calcium carbonate gel. It sounds like you have the right approach, ensure your staff have training in the self-treatment and peer treatment so they don't have to wait for a first aider

I've worked on a project where the client used this chemical and while we never had to deal directly with it, it did feature along the way. It is highly dangerous. I don't think I've ever seen an MSDS with more warnings. If you look online you can easily find an MSDS to review but what you must do is get one from the supplier of the chemical. The MSDS has all the information you require regarding what you need to do.

Hydrofluoric acid can have delayed effects with the exposed person only noticing a problem a considerable time later. Calcium GLUCONATE gel is supplied for those at risk of exposure to take home and administer if delayed symtoms show. This helps minimise the amount of damage done as the HF 'seeks' (not perhaps the right phrase but you get the idea) the calcium. A couple of pointers to note; - it must not be applied to eyes - gloves should be worn when applying or you risk the chance of two burns for the price of one - your employees should also have information to give to the hospital. It wont be the first time Hydrofluoric has been heard as hydrochloric and the wrong treatment given. The information will also raise your casualties profile and ensure prompt treatment. Finally, calcium gluconate gel only lasts a year John
