If paint, corrosion, or rust is discovered on a sprinkler head, what is the required action?

When paint, corrosion, or rust is found on a sprinkler head, the appropriate action is to replace the sprinkler head. This is crucial because any obstruction or deterioration of the sprinkler head can significantly impair its functionality. Sprinkler heads are designed to operate without interference, and the presence of paint or corrosion can affect their responsiveness, leading to potential failures in fire suppression during an emergency.

Replacement ensures that the sprinkler system remains reliable and compliant with safety standards. Simply cleaning or repainting the sprinkler head may not restore it to an effective operational condition, and documenting the issue, while useful for record-keeping, does not address the immediate risk posed by a compromised sprinkler head. Therefore, replacing the head is the definitive action to maintain the integrity of the fire safety system.
