You want to be sure that your Northern California business stays fully protected from fires. That includes regular check-ups of your fire protection gear, including fire extinguishers. Nearly everything in life has an expiration date, and fire extinguishers are no different! They may reach the end of their useful life, begin losing efficacy or have been partially discharged, but can you safely dispose of them at your local waste control facility? Generally, the answer is no — but you can safely dispose of these used fire protection devices.
