What should be done with a corroded non-rechargeable shell?

A corroded non-rechargeable shell should be discarded because corrosion compromises the integrity and reliability of the fire extinguisher. Non-rechargeable extinguishers are designed for single use, and once the outer shell has corroded, it is no longer safe to use. Corrosion can lead to leaks, reduced performance, and potential failure to function when needed in an emergency situation.

Fire extinguishers must be trustworthy and effective; therefore, any that show signs of significant wear, damage, or corrosion should be removed from service immediately. Proper safety protocols dictate that rather than attempting to repair, repaint, or store a compromised extinguisher, it is essential to ensure that only fully functional and intact equipment is available for use in emergencies. Discarding the unit helps maintain safety standards and protects individuals from using an unreliable fire protection device.
