    Servicing extinguishers, according to code, helps ensure they will operate properly when needed. Proper recordkeeping allows building owners, insurers, and AHJs to check that the periodic servicing was recorded properly. Making sure that the service work was done correctly and the records are accurate satisfies all parties that the extinguishers are up to code and ready for a fire emergency.
