What action should be taken if a non-rechargeable dry chemical fire extinguisher fails inspection?

When a non-rechargeable dry chemical fire extinguisher fails inspection, the appropriate action is to remove and dispose of it. Non-rechargeable extinguishers are designed for single use and are not intended to be recharged or refilled after they have been used or have reached the end of their service life. If these extinguishers fail inspection, it indicates that they may not function correctly in an emergency, posing a significant risk to safety. Proper disposal ensures that these units do not remain in circulation, thereby preventing potential misuse or reliance on equipment that could be ineffective during a fire emergency. This action aligns with safety regulations and best practices for fire safety equipment maintenance.
