Can someone advise me over this? In our pathology labs, we have conventional AFFF Fire extinguishers. I have been advised to replace these with AR - AFFF extinguishers, and replace existing water extinguishers with AFFF. The interim fire adviser has suggested this, along with the maintenance company. These existing extinguishers have been here since the year dot..... The labs do use a lot of alcohol solvents when testing. Thanks for any advice. Cheers Ed

Hi Ed, I'd agree with Ed,follow the advice you've been given and make sure you're all trained on which extinguishers to use in which situation and how to use them properly. Here's a quote from a web site explaining the benefits of AR-AFFF extinguishers: Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) concentrates, when proportioned at the appropriate rate, form a vapor-suppressing seal for rapid control of both hydrocarbon fuel fires (diesel, gasoline, kerosene, etc.) and polar solvent fuel fires (alcohol, ketones, methanol, and MTBE products).
