If this photo had been taken after June of 2013 or sometime before June of 2014, there wouldn’t be an issue with this fire extinguisher. However, it was taken recently and is well past time for an inspection.
While the extinguisher may work, as it says on the inspection tag, “Void 1 year from Mo. Punched.” At a minimum, fire extinguishers must be visually inspected monthly, with a maintenance check done annually. Rechargeable fire extinguishers require more in-depth inspections every six years. This involves conducting a hydrostatic test, which requires the fire extinguishers to be emptied, placed under water and subjected to pressures exceeding their ratings.
