What does discoloration or degradation of the extinguishing agent indicate?

Discoloration or degradation of the extinguishing agent in a fire extinguisher can be a significant indicator that the extinguisher is no longer effective. Fire extinguishing agents are designed to remain stable and functional over time, and any visible changes, such as discoloration, can signify chemical breakdown or contamination. This deterioration can impair the ability of the extinguisher to discharge effectively when needed, potentially compromising safety during a fire emergency. Therefore, it is crucial to regularly inspect extinguishers for any signs of degradation and take necessary actions, such as recharging or replacing the unit, to ensure readiness.
