Fire Extinguisher should be tested every?

In the US, most state laws and the NFPA (national fire protection agency) require annual testing. Another view: Actually, TESTING is not required by any rules, annually, for portable fire extinguishers. TESTING is required generally at 12 years from date of manufacture. Monthly inspections and Annual INSPECTIONS are requred as well. Barry Cole Preferred Safety 303-477-8414
