How often should sprinkler heads in commercial cooking equipment and ventilation systems be replaced?

Sprinkler heads in commercial cooking equipment and ventilation systems should be replaced annually to ensure optimal performance and safety. This frequency is crucial because these systems are subject to grease build-up, heat exposure, and other contaminants that can hinder their effectiveness in an emergency. Over time, the operational reliability of the sprinkler heads can diminish due to wear and tear, making regular inspections and replacements necessary to conform to safety regulations and maintain fire safety standards. Regular annual replacement helps safeguard against potential failures during critical moments when fire suppression is needed most, thus protecting both life and property.
