I called to schedule the fire extinguisher inspection at this location. Upon arrival I did a quick site survey then proceeded to physically inspect each fire extinguisher. I checked them for proper placement and to make sure that they had the proper signs. I then checked each fire extinguisher for hose blockage and to make sure the gauge was in the green. I found that they needed an FE36 for a clean room. I sold them one of these fire extinguishers. I concluded the inspections and let the customer know that unless the gauges go into the red or the fire extinguishers are used they are good for another year.
