This customer called and wanted to get their facility trained on using fire extinguishers correctly. We made the appointment and I showed up with a lot of fire extinguishers to try. I brought CO2, ABC and water fire extinguishers. I let those that wanted to try each to put a fire out in our fire pan that I brought. Everyone that tries gets added to a sheet showing they are trained in the basics of fire extinguishers. Once this was all done I loaded up and let them know if they needed another class to let me know. I also asked if they wanted to do this annually. I then let them know when their annual fire extinguishers were due and I would see them for that inspection.
