See if insurance sales, lead seals are in place and, if not, are invalid
3. Looking at the pressure table (with the exception of carbon dioxide extinguishers, the rest of the fire extinguishers have a pressure table), the pressure table pointer indicates a valid qualification in the green zone, the yellow zone indicates too much pressure and the red means that the pressure is insufficient or ineffective。
4. Newly acquired, refilled after five years and once used or filled every two years
