Can cleaning chemicals be applied to fusible links and detection devices if they are heavily caked with grease?

Cleaning chemicals should not be applied to fusible links and detection devices, even if they are heavily caked with grease. The materials used in these safety devices are specifically designed to function under extreme conditions, and the introduction of cleaning chemicals can compromise their integrity and operational effectiveness.

Fusible links are designed to melt at a specific temperature to activate the fire suppression system, while detection devices rely on sensitive mechanisms to detect smoke or heat. Applying chemical cleaners can leave residues that interfere with their function or cause deterioration over time.

It's essential to maintain these devices in their original state and ensure they are cleaned in accordance with manufacturer guidelines, which generally do not include the use of chemical cleaners. Regular maintenance should focus on ensuring these components are free from obstructions and in proper working condition without risking their functionality through chemical exposure.
